2022 Tesla Model Y Complaint Log

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (MCU) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known MCU system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.

Car was on FSD Software version 2026.8.6 Car had trouble centering itself in the lane (so it does a “ping pong effect”) which I believe caused the car to lose control No others cars involved no injuries Lo and behold, 2 days later a software update (2026.8.6.1) to correct this issue is issued by Tesla I have dashcam and footage of the accident which shows car was on FSD and also shows the “ping pong effect”

My 2022 Model Y Performance developed severe front-left inner shoulder tire wear caused by a suspension alignment defect. On 4/7/2026 at 57,974 miles, Les Schwab diagnosed excessive shoulder wear due to alignment issue, deemed the tires unsafe, and required a liability waiver before I could leave (WO #XXX). I drove to Tesla Portland. Tesla’s own ExpressAlign check confirmed the front toe was out of spec, with multiple values flagged red on their equipment. The left front toe was the most severe, matching the wear pattern Les Schwab diagnosed that morning. Tesla charged me $1,874 for four new tires but did NOT perform a corrective alignment. Their own post-install report shows front toe STILL flagged red (left front toe slightly worse than before). They released the car on new tires with alignment still out of tolerance. I had paid Tesla for an alignment in Feb 2025 at 33,261 miles to prevent uneven wear. It failed within 24,713 miles with no suspension impacts or damage. The specific inner shoulder wear pattern, validated independently by both Les Schwab and Tesla on the same day, is consistent with the documented suspension geometry defect in 2020-2024 Model Y vehicles. I request NHTSA consider expanding the scope of recall 21V-835 (Tesla SB-21-31-003), which addressed front suspension lateral link issues on 2019-2021 Model 3/Y, to include 2022+ Model Y vehicles exhibiting the same alignment geometry failure. This is a safety hazard. Les Schwab required a liability waiver. I replaced all four tires as a safety necessity to transport my children. The underlying defect appears to be a factory design or manufacturing issue that Tesla’s alignment service does not resolve. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Following a 25-day repair at a certified collision center due to an earlier accident, the vehicle's Full Self-Driving (FSD) and Active Safety Systems began failing. The vehicle repeatedly failed to keep speed and failed to stay centered in the lane. On March 25, 2026, while traveling at low speed on a public roadway with FSD actively engaged, the system failed to maintain a stable path and incorrectly steered the vehicle into a curb, causing property damage to the wheel. This failure put my safety and the safety of surrounding traffic at risk by executing an unpredictable steering maneuver that the active safety systems failed to prevent. The vehicle was taken to the manufacturer's service center twice with this specific complaint prior to the curb strike. The service center investigated and officially concluded that this was not a software issue, stating that they could do nothing else. They deferred the resolution back to the collision shop, citing likely camera/sensor physical misalignment from the 25-day body repair. The collision shop is now refusing to review the vehicle or inspect the hardware, claiming lack of visible exterior damage despite the internal service team stating this is a latent hardware alignment defect. The vehicle is currently in the same failing condition and available for inspection upon request. No warning lamps or error messages appeared on the screen prior to the failure or the curb strike. The symptom of unpredictable lane tracking first appeared immediately upon receiving the vehicle back from the collision repair earlier this year. Note: I have a formal data privacy request pending with Tesla to pull the exact chat logs showing their refusal to service this hardware defect. I will provide these to the investigator upon follow-up.

Tesla Model Y Performance with 47,000 miles. Driver's side, rear passanger door would not open. No accident or damage to the car or car door. Door could not be opened from the inside nor the outside with the handle. ISSUE: The Emergency Door release in the pocket of the door failed to release and open the door.

My driver side headlight assembly stopped working. The headlight assembly includes the driving lights, high beams, and turn signals. I am open to having this product inspected upon request. This impacts the safety of me and others due to decreased visibility and the inability to appropriately indicate when I am turning. The dealer has not reviewed this yet, but I have a scheduled appointment on Friday, April 24. Vehicle has not been inspected by any third-party, improving manufacturer, police, insurance, or other representatives. There were no warning, lamps, messages, other symptoms of the problem prior to failure. The failure first appeared at around 55,000 miles, which was 5000 miles beyond my warranty. I believe that Tesla is pushing out updates that intentionally cause light assemblies and other high priced items to stop working after the warranty. there are multiple instances people replacing the same fixture after their warranty period has expired. Tesla charges $2000 to replace one light fixture. I believe this is fraudulent and corrupt business practices by Tesla.

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (GPS/FSD/Navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'EXTREMELY POOR BRAKE FEEL' and 'EXTREME RUST BUILD UP' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of GPS and FSD features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

The contact owns a 2022 Tesla Model Y. The contact stated that the steering wheel material had been unraveling. The contact received notification of TSB Number: SB2332003. A Tesla Service Center was contacted via the Mobile App Chat feature, and informed the contact that the vehicle would be repaired at the owner's expense because the warranty had expired. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 70,000.

HV failure failed on 2/12/26 @ 62k miles. Multiple errors (BMS_d265 Replacebatterypack, BMS_a079_Max_charge_limit_exceeded, and BMS_a029_dSOC_limiting. Frequent errors while driving, especially during acceleration on highway which were confusing/distracting. The errors seem to indicate danger with the vehicle and to not charge the vehicle/limit the charge to prevent further damage to the vehicle/surroundings. Took into service center on 2/13/26. Confirmed need a replacement HV Pack.

Around 02/10/2026, all of ADAS functions of my 2022 Tesla Model Y has suddenly stopped working, and the rearview was just black. On 02/27/2026, Tesla service diagnosed the car and tole me that the car computer should be replaced and its total repair cost would be about $3,200. My car's mileage was 51,000 at the onset of the problem, so just passed the standard 50K warranty. My car has total loss of rearview camera (FMVSS 111 violation) and loss of Active Safety Systems (AEB/FCW), but Tesla refused to repair a federally mandated safety defect if I don't pay the full repair cost.

Front driver side lower control arm bolts came off without external forces. Both bolts fell off with no damage to the threads. Tesla service stated that upon inspection of their technician it is determined that the front left lower link bolt was either not properly seated or missing which caused a defective front lower link bushing. (I included a screenshot of their finding). The damage was caused by this defective part leading to the car not being unsafe and inoperable due to no steering and no drive as well as wheel literally coming off the car while in motion. Luckily I was simply backing into my driveway when this failure happened narrowly avoiding a potential life threatening accident. I have researched that this was a known issue for my exact make and model just months before my car was purchased in march 2022. I have attached the document "Part 573 Safety Recall Report 21V-835. Unfortunately, Tesla refuses to admit the defect when it was time to pay for the repairs despite clearly admitting it on their initial inspection, leaving me with the repair bill.

Front driver side lower control arm bolts came off without external forces. Both bolts fell off with no damage to the threads. Tesla service stated that they were possible not seated or missing per their inspection. Further er damage was caused by this defective part leading to the car not being operable due to no steering and no drive as well as wheel literally coming off the car.

While driving, the front left brake caliper detached, causing immediate damage to the wheel and a tire blowout. There was no recent brake, wheel, or suspension service (over two years). Tesla is repairing the vehicle for an estimated $2,336.41 but did not clearly identify root cause. This was a sudden brake system failure that could have resulted in loss of control. I am reporting this as a potential safety defect.

HVAC system failure in sub-freezing weather causing loss of windshield defrost and cabin heat. Tesla has acknowledged this as a known hardware design limitation of the heat pump/octovalve system but is refusing repair coverage outside of warranty. This condition affects driver visibility and winter driving safety.

The contact owns a 2022 Tesla Model Y. The contact stated that while driving at an undisclosed speed and attempting to make a left turn, the Forward Collision Avoidance system activated while the accelerator pedal was depressed; however, no object or persons were in front of the vehicle. The vehicle was taken to a service center to be diagnosed; however, the service center stated that the obstacle-aware acceleration system was activated, and that the vehicle performed as designed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 35,000.

We live on a road with a steep embankment. My wife backed across our driveway and when she put the car from reverse to drive it accelerated uncontrollably. She hit our mailbox, then a power pole across the street, a driveway across the street then over the embankment where she hit a retainer wall another wooden railing and finally came to rest against our neighbors house. If she wouldn’t have caught the edge of the house she would have went down approximately 150 foot embankment. Not only the car accelerated on its own it is supposed to automatically brake, it didn’t and the airbags never deployed. This all this happened right after it went through an automatic update. The car was totaled, with my wife getting a concussion and a lot of muscle injuries. There was no warning lights prior to event and we reported it to Tesla and all they did was send camera images which we had. The car is now in possession of Wawanesa Insurance because it was a total loss

On January 12, 2026, I was involved in a multi-vehicle collision on I-4 West near US-27 Off Ramp in Polk County, Florida. My vehicle was struck on the left rear quarter panel causing me to lose control, hit a second vehicle, and travel off the road to the hazard lane. The vehicle was declared a total loss by the insurance company. Despite the severity of the impact, none of the airbags deployed. The Florida state crash report confirms airbags were marked as Not Deployed. The vehicle is currently at a salvage yard and is available for inspection. No warning lamps related to the airbag system were present prior to the crash. The failure of the airbag system to deploy in a total loss collision put the driver at significant risk of serious injury.”

The contact owns a 2022 Tesla Model Y. The contact stated that while charging the vehicle or using the onboard navigation system to search for a charging station, the entire infotainment central processing unit shut down unintendedly. The contact stated that there was an abnormally low humming sound, and approximately 30-seconds later the infotainment screen shut down unintendedly. The contact had taken the vehicle to a local dealer where the battery and the coolant system were checked. The contact was advised by the dealer that they were not able to isolate the failure and needed to run additional diagnostic testing. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 22V296000 (Back Over Prevention, Equipment); however, when the dealer was contacted about the recall, the contact was advised there was no recall associated with the VIN. The manufacturer was not informed of the failure. The failure mileage was approximately 70,000.

The contact stated that they rented a 2022 Tesla Model Y. The contact stated that the vehicle was supervised in autonomous mode when it suddenly turned left while driving at approximately 45 MPH, causing it to hit an electrical box nearby. The vehicle then steered itself back onto the road and shortly after, turned off the road towards the right and crashed into a tree, where it came to a stop. There were no warnings or notifications that were displayed during the incident. The air bags did deploy. The vehicle did not allow the driver to correct the direction of the vehicle or disable the autonomous mode setting. The vehicle had caught on fire. The contact and the other passenger, sitting in the front passenger seat of the vehicle at the time, were able to exit the vehicle. The fire department was called and extinguished the fire. The police department was contacted, and a police report was filed. The vehicle was towed and totaled. The contact received a broken left wrist, a sprained right foot, and seat belt bruising to their lower stomach and chest area. The passenger in the vehicle received seat belt bruising. Medical attention was needed. The contact rented the vehicle through Turo and informed the person they had rented from. The contact was not sure if the incident was reported to the dealer or manufacturer by the owner. The contact stated their attorney contacted the manufacturer and informed them of the incident in an attempt to retrieve data information from the vehicle at the time of the incident. The failure mileage was unknown.

On January 9th my wife got into an accident in our 2022 Tesla Model Y vehicle. She reported that as she was backing out of a prking spot in a strip mall, the vrhicle suddenly accelerated backward involuntarely which resulted in colliding with a vehicle which was approaching from the rear side. My wife reported the speed was so violent that she felt dizziness. When she took the car bto the Tesla shop for repair by the insurance, the Tesla repair people discounted her reporting and did not do any follow-up to investigate the issue. Note the onboard camera recorded the swift movement of the vehicle and I will try to upload it. We have read that such problem was looked into by the NTHSA in the past and that it is being revisited again. Note that that Tesla has determined the vehicle as being totalled and has kept it at their shop. Please let us know your thoughts on this matter so if this is a serious problem that it can be addressed so it won't happen to others. My wif was lucky she didn't get hurt and also she didn''t heart others. Please note I am currently traveling out of the country and will be be back in the US on March 12, 2026. You can contact me via my email or I will be available for phone conversation on the indicated date. Also please note I could not upload the recording of the on board camera because of the format incompatibility. THe phone number included is my wife's and please feel free to contact her.

The contact owned a 2022 Tesla Model Y. The contact stated that while the contact’s daughter was driving at approximately 70 MPH under significant rainy weather conditions, with autopilot mode engaged, the auto pilot became inoperable. The contact stated that the driver attempted to steer the steering wheel; however, the steering could not be steered, causing the driver to lose control of the vehicle. The vehicle subsequently collided with a concrete wall and might have collided with another vehicle. There was no warning light illuminated. The contact stated that all the air bags of the vehicle deployed during the crash. As a result of the incident, the driver sustained a nose injury and facial lacerations. The driver was transported to a local Emergency Room for medical treatment. A police report was filed. The vehicle was towed and deemed a total loss. A Tesla service center was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, but no assistance had been provided. The failure mileage was approximately 55,000.

I got into my car two days ago and the computer screen was black. I have tried everything to reset it, holding down both scroll wheels with the brake pressed for up to 2 minutes, unplugging the low voltage battery overnight and plugging it back in, and even doing the hard reset at the disconnect under the rear passenger seats and my computer will not turn on. I can't see any information about my speed or how much charge I have, I can't turn on climate controls and it's the middle of winter and I live in the mountains of Colorado. I can't even open my glove box without the screen. From everything I read, it sounds like an MCU failure, my vehicle has the newer MCU2. Tesla quoted about $800 for a tow and it sounds like the replacement costs could be $2500+

I am reporting a repeated safety defect that happens only in rainy conditions. My 2022 Tesla Model Y repeatedly shows critical safety warnings including “Automatic Emergency Braking unavailable”, traction and stability control disabled, and “Vehicle Hold unavailable”. This has occurred during normal driving in rain every rainy season for 3 years, despite 4 service visits and parts replacement including the inverter. It started when I was pregnant and is now ongoing with my newborn in the car. The system failures happen while driving in normal wet/slippery conditions and greatly increase the risk of a crash. This appears to be a systemic safety defect, not driver error, and Tesla has not fixed it after multiple service attempts. Events & Dates: •First occurrence: Feb/2024 •Service visits: 02/01/2024 1. Verified customer's concern via vehicle log data. Technician reviewed the vehicle's logs and found that the vehicles communication system was faulted. Technician was not able to duplicate the concern at this time. Performed diagnosis and found no issues present at this time. Verified vehicle's communication system is operating as designed at this time. No further repairs are recommended at this time. Recommending customer to continue to monitor situation at this time. 2. Updated vehicle to latest available firmware version per service bulletin. •Most recent occurrence: 01/01/2026 fyi today is the 4th time I’ve indicated this issue , and this is during my pregnancy again, I feel extremely stressed and helpless

The headlights turned off while driving. Not being able to see where you're going is risky. The problem has occurred twice under the same conditions - light snow covering on the car. It has not been reproduced at dealer or service center. Components have not been inspected. The headlights operate properly when the snow is removed. No warning, messages or symptoms. Tesla Assist states that if there if driving in snow or low viz conditions, the headlights should be turned on manually, which is not intuitive or appropriate given the advanced nature of the car

On December 30th, 2025, my wife experienced a serious and unexpected safety event while using Autosteer in one of our Tesla Model Y cars (we own two of them). The version of the vehicle software in use was v12 (2025.26.8) and the Full Self Driving (Supervised) Software was v12.6.4. The vehicle came to a complete stop at a red traffic light on northbound San Gabriel Blvd in Pasadena at the intersection that controls entry to the I-210 West. After waiting for approximately 55 seconds, Autosteer initiated forward movement into the intersection while the traffic light was still red. The vehicle’s movement was not caused by driver input. My wife’s feet were away from the pedals at the time. There was no visible lead vehicle movement or other obvious external trigger. Fortunately, my wife was attentive and immediately disengaged Autosteer, brought the vehicle to a stop, and carefully reversed back into a safe position. Moments later, multiple fast-moving vehicles crossed the intersection in front of her path. Had she not intervened promptly, there was a realistic risk of a serious side-impact collision. This serious incident was reported to Tesla on 12/30/2025 including a video of the incident. In my correspondence, I requested that all relevant vehicle telemetry, Autosteer/FSD logs, and any uploaded video associated with this time and location be preserved and reviewed. As of today (7 weeks later) they have not followed up with me. The 18-second video was recorded by an independently installed Viofo dashcam, which clearly shows: . the vehicle stopped at a red light, . the light remaining red, . and the vehicle beginning to move forward unexpectedly.

1. Incident Description (FSD Failure) "While operating the vehicle using FSD (Supervised) on December 30, 2025, at approximately [Time], the vehicle failed to detect and completely ran through a red light/stop light at the intersection of [Street Name] and [Cross Street]. I had to take over the vehicle to avoid a potential collision. The system did not provide a warning or attempt to brake for the traffic signal." 2. Control Failure (Sliding/Steering) "Under low-speed conditions (approximately 13 mph), the vehicle suffered an uncontrolled loss of traction and directional stability. The Traction Control System (TCS) failed to intervene or stabilize the car. I was forced to perform a manual steering intervention to correct the slide and maintain my lane. This occurred at [Location/Address]." 3. Hardware/Exit Concern (Door) "The vehicle has a mechanical defect in the [Front/Rear] door. It requires excessive physical force (hard slamming) to latch properly. I am concerned that in an emergency, the door may fail to open or close correctly, posing a safety risk to passengers." 4. Summary of Risk "I no longer feel safe operating this vehicle. The combination of an autonomous driving system that ignores traffic signals and a stability system that fails at school-zone speeds makes this vehicle a life-threatening hazard to myself and others on the road."

A tire experienced a sudden bead-area blowout while the vehicle was traveling at freeway speed. There was no pothole, curb, debris, or roadway impact. The failure occurred approximately ten days after installation. Inspection shows failure at the tire bead adjacent to a wheel defect. The wheel was represented as new at installation but shows evidence of prior material removal and cosmetic reconditioning, including rounded aluminum exposure and surface striations inconsistent with fresh impact. The compromised wheel-tire interface caused sudden bead unseating and rapid air loss.

The lateral lower front right suspension link and its securing bolts failed, causing the control arm to drop and the vehicle to become uncontrollable. (The bolts actually fell out on the ground) This was the second repair involving the same suspension area, with prior work performed on March 27, 2025. The replaced components should be available for inspection upon request. The failure caused the vehicle to become uncontrollable while backing into a parking spot. Had this occurred at road speed, it could have resulted in a complete loss of control, posing a risk to the driver, passengers, pedestrians, and surrounding traffic. Tesla service confirmed the failure during the January 5, 2026 repair and replaced the affected suspension components under Invoice #[XXX]. Tesla service technicians inspected the vehicle during both repair visits (March 27, 2025 and January 5, 2026). There is no record of inspection by police or insurance representatives. No warning lamps, messages, or prior symptoms were present. The failure occurred suddenly while backing into a parking spot with no advance indication. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Full Self Driving caused my Tesla to enter an intersection while the light was red. The FSD stopped at the red light on Monday Dec. 22. 2025 at 9:37 am. After a few moments is began to drive from the correct stop and enter the intersection while the traffic light was red. I had to manually take control to prevent it from continuing thru.

Incident Summary: Car Computer (HW3) suffered internal hardware failure on 12/17/25 following software update 2025.44.3. While the media screen and rearview camera functioned, the Autopilot Board (APB) was "MIA." Tesla Randolph (Invoice #3000S0015357298) confirmed the internal failure and replaced the unit. Safety Risk: Failure disabled safety-critical ADAS: Automatic Emergency Braking (AEB) and Forward Collision Warning. Driving visualizations were severely compromised; the vehicle failed to detect pedestrians or lane markings while in motion, creating an immediate collision risk. The car’s active safety "intelligence" was essentially blind despite the camera feed being visible on the screen. Inspection & Contradictions: Tesla Service confirmed the "internal failure" (12/19-12/23). Note: The Service Manager verbally claimed "no codes," but the official invoice explicitly states technicians "found multiple alerts present." Part was retained by Tesla. Warning Symptoms: Failure followed a software reboot loop. Symptoms (MIA board/power cycle failure) match Recall 25V-002. Vehicle had only 36,289 miles. Reporting as potential HW3 defect expansion.

While slowly backing out of a parking space at a Whole Foods in San Jose, CA, the driver's-side front wheel suddenly collapsed without warning. The front tire completely locked up, preventing further movement. Upon inspection, I found two bolts lying on the ground and the lower control arm detached and hanging loosely. The sudden jolt from the tire impacting the vehicle's body also caused minor damage to the plastic underbody cover. I had the car towed to the Tesla Service Center at 2801 Northwestern Parkway, Santa Clara, CA 95051, and it is now in their possession. Fortunately, this occurred at very low speed in a parking lot—if it had happened on the freeway, the outcome could have been catastrophic. I've since discovered similar incidents reported by other Tesla owners in this forum thread: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car stopped in a busy freeway saying electric issue and doesn’t give sufficient time to drive to shoulder. This is the 2nd time this happened within 2 weeks. First time, tesla said high voltage controller had an internal issue with voltage sensing. the hv controller was replaced along with pyrotechnic fuse. Tesla assured this shouldn’t repeat and it repeated again. This has kept us in a catastrophic situation. I request immediate attention to this error and matter.

During a snowstorm, the headlights caused blinding visibility issues due to the reflected light from the snow flakes. Normally, using low beams fixes this problem. I tried all combinations of headlights during the drive- auto high, high, auto low, manual low, just parking lights. All resulted in horrible visibility conditions that limited speed to around 20 MPH. The vehicle was inspected by Tesla service. Tesla reported the headlights operate as designed. There is a light bar above the headlight that remains on when driving and this illuminates the snow. This lightbar should turn off at night or at least have an option to turn off by the driver.

The contact owns a 2022 Tesla Model Y. The contact stated while his wife was driving 40-50 MPH in the evening with Self-Driving mode activated, the vehicle failed to decelerate while driving onto the exit lane and crashed into the rear of another vehicle. The contact was occupying the front passenger's seat during the incident. The front driver's side and passenger's side air bags deployed. There was no reported injury. The vehicle was towed to the residence. The vehicle was later towed to a Tesla autobody repair shop to be repaired. The vehicle was then towed to the autobody repair shop recommended by the insurance company. The vehicle was later totaled by the insurance company due to the cost of the air bags replacement. A police report was filed. The manufacturer was notified of the failure. The failure mileage was approximately 30,000.

To the National Highway Traffic Safety Administration, I am filing a formal complaint regarding a dangerous safety defect in the 2021 Tesla Model Y. On December 2, 2025 at approximately 4:25 PM, my vehicle suffered a sudden, complete electrical shutdown while I was driving, with no warning and no opportunity to reach safety. Critical details: The vehicle displayed an electrical system message, then instantly powered down. I lost all ability to steer or move the vehicle, which remained immobilized in active traffic. Hazard lights did not function, leaving the vehicle unmarked and invisible to oncoming vehicles. Electronic systems failed, requiring manual release of the driver door. The incident occurred at dusk and blocked the roadway, placing myself and others at significant risk. This failure presented an immediate threat to life and safety. I have since discovered that other Tesla owners have reported similar abrupt electrical or drive-unit shutdowns, suggesting this may represent a broader systemic defect. I am formally requesting that NHTSA investigate whether this issue meets the threshold for a safety recall and whether Tesla’s systems contain a defect capable of causing sudden, uncommanded shutdown while driving. Thank you for your prompt attention to this matter. I am prepared to provide all supporting documentation, including incident details, screenshots, timestamps, and service correspondence.

I have repeatedly had electrical failure in the vehicle in the form of a "Reduced Power Alert" which renders the vehicle with significant limitation to drivability. This places the vehicle in "limp mode" and this frequently occurs on the highway. Once this Alert appears the vehicle has limited propulsion, limitations to steering and braking as well as other electrical systems. It has been to the dealership for repair on 4 occasions without remedy. It is leaving us on the highway in a dangerous situation repeatedly. It's not a one time event. There were 20 Alerts showing on the screen when I limped it into the dealership once again on [XXX] having nearly wrecked on [XXX] just before the [XXX] exit. The reason this is so dangerous is the failures occur at higher speeds such as highway driving. Leaving one with an immediate loss of forward motion as if you've hit the brakes but vehicles behind you have no warning. This is going to end up with someone getting rear ended or worse. Social media indicates it is a prevalent and not well understood recurring problem. Tesla has been quietly repurchasing vehicles from angry owners. Dreadful. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My high voltage drive inverter experienced a failure resulting in loss of all power as well as regenerative braking. Mechanical braking and steering remained available. There were no warnings or indications before the failure. After the failure there were warnings that the propulsion system had failed and to pull over immediately.

My 2022 Model Y, 213k miles, battery health 77%, no issues until Beginning of November 2025. After Tesla’s update, BMS_a079 popped up, capped charge at 22%. No dead cells, no imbalance—pure software bug remotely triggered by Tesla. Service refused written diagnosis, only said ‘nine thousand dollars for new battery. Risk of stranding.

Driver side rear outer camber bolt lost the nut holding the bolt for the camber arm. Rear tire cambered in greatly. Upon disassembly saw that bolt has backed out about 75% because of the absence of nut. If bolt had completely backed out the camber of the rear wheel would have collapsed completely and very possibly caused an accident.

Two days ago, replaced two rear tires at the American Tire Depot and ask them to alignment service. After tire replacement, mechanic showed me the front two control leg arms were cracked and seemed it need to be replaced. That looks pretty bad and never had any issue from other vehicle. Contact to Tesla and was told that out of warrant (50k, current mileage 54k) - i found out there are many accident because this .

On October 13th 2025, while driving, I began to hear a clunking and rattling sound from the front left wheel area when braking. Concerned for my safety, I brought the vehicle to a local independent brake specialist for inspection. Their technician found that one of the two bolts securing the brake caliper was completely missing, and the remaining bolt was approximately halfway backed out. The shop explained that this condition presented an immediate risk of caliper detachment and total brake failure, potentially leading to serious injury or death. After both bolts were replaced and properly torqued, the brake noise that Tesla had previously attributed to “pad burnishing” disappeared entirely. This indicates that the squeaking and vibration symptoms Tesla dismissed were, in fact, caused by an improperly secured caliper—a direct safety issue, not a normal wear condition. I notified Tesla legal of this problem (via certified mail) on October 13 2025 and requested a response within 14 days. I have received no such response, nor have I been contacted for further investigation into this dangerous situation with my vehicle.

The Tesla model Y Performance has a tire wear problem that causes uneven wear and creates cupping that occurs within 7500 miles of tire wear. There is also a weird sound even when you have new tires on the vehicle. The noise grows as your speed goes up it is almost painful at 70mph. It is a known issue and Tesla refuses to address the problem even though they are aware of it. This cupping issue creates a loud noise within the vehicle and reduces the tire mileage to under have of the rated mileage. I have taken my model Y in three times and while they state they are unable to work on the noise unless I replace my tires. I believe there is other problems with the suspension because of the noise the model y make regardless of the cupping.

On [XXX], while using Full Self-Driving (FSD) to drive to a hospital in Oak Park, Illinois, the vehicle experienced sudden unintended acceleration during the disengagement of FSD. As the vehicle approached the hospital area, I initiated disengagement of FSD to manually enter the parking area. During—or immediately after—the disengagement, the vehicle suddenly accelerated at full power without warning, causing an immediate loss of control and a collision with a nearby fixed structure. No system warnings or alerts were issued prior to the event, and the acceleration was so abrupt that manual intervention was not possible. This occurred in a low-speed, street-level environment where no acceleration was intended or expected and does not correspond to any normal driver input. Based on review of preliminary incident data provided by Tesla, there appear to be irregularities during the FSD-to-manual control transition, including missing or invalid input values, gaps in accelerator/brake/steering signals, and speed readings inconsistent with the crash severity. These indicators suggest potential instability in the real-time control system during disengagement. This report is submitted due to concern that sudden unintended acceleration during FSD disengagement may represent a safety defect with potential risk to drivers and the public.

Tesla Dashcam fails to record the accident. I have requested data from Tesla; however, all the related data (call, messages) I obtained on the date is missing.

Stress crack appeared starting at edge after no apparent exterior damage or external factors.

One day I was exiting the vehicle, and as I swung my leg out to get out of the car the outboard panel broke. Nothing caught on it, it just broke as my weight shifted. As the technician came out to inspect it for repair, it was claimed that this was a common repair. The seat controls are on this panel, so when this happens, this means wires are loose, while the seat automatically moves for use. This changes how the seat positions itself, and the panel interferes with the door closing properly, the seat position.

I keep getting alerts that there is a front right safety restraint system issue and service is required. Repair note Nov. 14 2024 stated: Safety Restraint alert has been intermittent over at least the past year. Customer has had previous Service Visits for same alert (RCM2_a136_sideAB1stRowROpen). Issue seems to be somewhere within the harness affecting the passenger side airbag. Replaced the Front Right (passenger) seat harness.Alerts are currently cleared. Feb 15, 2024 Repair Notes: Technician verified customer concern. Tech found the alert was for the 1st row passenger side airbag. Tech checked the connector in the seat and it was softset. Tech plugged it back in and made sure it was secure. Tech test drove and verified no alerts present.

Vehicle 2022 Tesla Model Y AWD with Long Range Battery (Steel Grey) VIN: [XXX] License Plate: [XXX] State: CA Production Date: 03/2022 Incident Date/Time: September 20, 2025 ~7:30 AM Location: [City, CA] Description: While using Tesla’s Full Self-Driving (FSD), the vehicle approached a construction zone with a red light. The car slowed as if preparing to stop, then suddenly veered toward the side of the road and struck a construction barrier/pole. The maneuver was unexpected and occurred too quickly to prevent impact. This raises concerns about FSD’s ability to handle construction zones, traffic signals, and obstacles. Injury/Property Damage: Vehicle declared a total loss. Driver sustained neck and back injuries. Request: I am reporting this as a potential safety defect and request NHTSA investigate whether Tesla’s FSD has deficiencies in detecting/handling construction zones and signals in these conditions.

2022 Tesla Model Y Long Range AWD VIN: [XXX] Current mileage: 71,967 SAFETY DEFECT: Power Conversion System (PCS) internal hardware failure causes sudden, complete loss of Supercharging capability and extreme vampire drain. Tesla technician’s own words – invoice #[XXX] dated 11/04/2025: “The problem was caused by an internal hardware condition in the Power Conversion System.” This is a manufacturing defect – NOT wear/tear. Safety risk: • Stranding hazard – vehicle stalls at 99%/95% on V3 Superchargers. • One documented trip (Indiana → Las Vegas) required 27 Supercharger stops and 14+ hours of charging instead of the normal 10–12 stops. • Vampire drain: 95% → 70% in 4 days parked (all features off) – July 2025. • Battery degradation: 16.4% loss at 72k miles (83.5% health, 268 mi range) – far above fleet average. Tesla knew since 49k miles: • Nov 20, 2024 – full HV circuit integrity check – goodwill $0 • Feb 19, 2025 – Service Manager [XXX] ran diagnostics and wrote “everything checks out great” • 15 service visits, 3 charge-port doors replaced – same root symptom Tesla now demands $2,503.17 out-of-pocket and refuses to release the vehicle until paid – despite admitting the defect in writing. Cybertruck loaner (provided by Tesla) exhibits identical 99% stall 5 times – proving systemic issue. Attachments (will upload): 1. Invoice #[XXX] – “internal hardware condition” 2.

In 9/2025 I noticed that the vehicle software was defaulting to a speed limit of 55 mph. I noticed that when in any form of autopilot and FSD it would accelerate to that speed. This happens in any situation before the car encounters a sign or an area that it's internal map corrects it, which is not common outside of major routes in Idaho. This includes paved marked roads, graded roads, single track dirt roads, my driveway and garage. Sometimes the car controls it's speed consistent with conditions, sometimes not. It can happen unexpectedly, and that's the issue. Where I have learned this is a problem, I of course turn off the AP or FSD and drive myself, however, if I am in driver assist mode and things are going well and the speed limit in the vehicle changes suddenly to the default 55 mph, it can take a moment for me to react. In October 2025 I reported this to my Tesla Service center as well as Tesla's over the air and on line email reporting options (from which I got no response). The service center entered a ticket directly with Tesla, and told me that that Tesla was aware. The explanation that came back was that it was due to a mapping update for the internal map of the car. They said it was the result of Google Maps setting the default speed limit in Idaho, which is where I live, to 55 and that this was due to a September 2025 update. They said it might be corrected with the next update, which has not occurred at this point (January 2026). This speeding behavior can happen suddenly and unexpectedly and seemingly randomly, and has the potential to injure pedestrians, the driver, and property, not to mention that it is also exceeding by far the legal speed limit. Drivers from other areas that may not be aware of the issue are likely to be caught unaware. There is absolutely no reason for the default speed to be 55, ever. It's unsafe, and unnecessary. It is rare to see a speed limit of 55 at all in Idaho. Most of the roads are above or below that speed limit.
