2021 Tesla Model Y Complaint Log

while traveling at approximately 80 mph with Full Self-Driving (Supervised) engaged, my vehicle experienced a simultaneous failure of the Full Self-Driving computer and the Media Control Unit (MCU) touchscreen. Without any prior warning, the touchscreen went completely black, and the vehicle immediately executed an uncommanded, sharp steering maneuver into the right lane. It was very apparent that if I didn’t take over it was going to continue crossing highway lanes and go off road. I have around 45k miles specifically on FSD and never has it failed in such an extreme manner. This sudden steering input put myself and other motorists at extreme risk of a high-speed collision or roadway departure. I was forced to physically overpower the steering wheel to maintain lane integrity and prevent a crash at highway speeds. The failure appeared to be a total loss of the vehicle’s primary visualization and automated steering systems, leaving me with no digital feedback regarding speed or surrounding traffic while the car was still in motion. Prior to this event, there were no warning lamps or symptoms such as GPS drifting or screen lag. I have since attempted a hard reset and a full power cycle, but the critical nature of this uncommanded steering at 80 mph suggests a systemic defect in how FSD manages hardware or software failures. The vehicle and its internal data logs are available for inspection upon request. This incident has been documented in the Tesla App under a service request for a full log review.

The paint on my Tesla Model Y is peeling and delaminating along both sides of the rear trunk/hatch seam, adjacent to the rear glass. The issue appears in the same location on both sides in a symmetrical pattern. There has been no accident, impact, or external damage to these areas. The peeling began gradually and has continued to worsen over time. The symmetry and location suggest this is not normal wear or environmental damage, but a potential defect in paint adhesion or manufacturing at the trunk seam. This condition exposes underlying material and may lead to further deterioration, including corrosion over time. I am reporting this as a potential manufacturing defect affecting durability of the vehicle exterior

Incident Date: April 11, 2026 Approximate Time: 6:30 PM Component(s): Unknown (Suspected: Electronic Stability Control, Steering, ADAS) Description of Incident: On April 11, 2026, at approximately 6:30 PM, I was operating my Tesla Model Y on a highway with a self-driving mode engaged. I experienced what appeared to be a sudden, unintended acceleration combined with an erratic "zig-zag" steering pattern across multiple lanes. I am not certain of the technical cause, but the vehicle’s behavior felt like a loss of system control that was not initiated by me or the road conditions. I had to intervene immediately to prevent an accident. Post-Incident Actions and Manufacturer Contact: I have since contacted Tesla Service, and while they confirmed that data for that date exists, my formal "Privacy Data" requests for those specific logs have come back empty or missing the relevant timeframe. Summary of Concern: I am reporting this because I suspect a serious software or hardware malfunction occurred, though I do not have the technical diagnostic to confirm which system failed. The combination of the vehicle’s erratic movement and the subsequent difficulty in obtaining the data logs for this specific window of time leads me to believe there is a potential safety defect that requires investigation.

Squeaking (lubrication failure) of the front suspension components, prematurely, are a common and widespread issue with Tesla vehicles. I have approximately 60k miles on my model Y and the front control arms are making noises. Tesla wants to replace a significant amount of suspension components at a high cost, instead of a recall (or creating serviceable lubrication points on these components). The NHTSA needs to hold Tesla accountable for faulty suspension design and lack of maintainability leading to premature failure.

The back drivers side seatbelt belt does not latch. The manufacturer refuses to fix without a fee.

The rear camera has failed posing a safety issue when reversing the vehicle.

**What component or system failed or malfunctioned, and is it available for inspection upon request?** The vehicle experienced a critical failure immediately on the same day of purchase, rendering it not functioning or inoperable. It was deemed to be preexisting from the dealership I bought it from. The battery is malfunctioning affecting the driving capacity and range. --- **How was your safety or the safety of others put at risk?** The failure created a significant safety concern, as the vehicle was not operating reliably immediately after purchase. This placed me at risk of being stranded and potentially exposed to hazardous conditions, including loss of transportation in unsafe or uncontrolled environments. Or stopping while driving. --- **Has the problem been reproduced or confirmed by a dealer or independent service center?** The issue was immediately reported to the dealership, and they acknowledged the problem by agreeing to an exchange of the vehicle due to its defective condition. It was confirmed by a service center of the car's manufacturer. --- **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?** At this time, the vehicle has inspected by the manufacturer. --- **Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?** Yes, although the manufacturer can't pinpoint when they started but said they had been on since ATLEAST March 10. My purchase was made April 1, undisclosed to me of this huge issue.

I was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [XXX] and [XXX] . We were completely trapped in the vehicle with no power. My [XXX] old remembered to use the manual latch to get out. I opened my door manually and It broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [XXX] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

While on my way to run an errand, I opened up the back door to strap my 2 year old in, when i closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

I own a 2021 Tesla Model Y with approximately 46,500 miles. The vehicle is currently displaying battery error code BMS_a079, and the battery will only charge to approximately 30%, which severely limits the driving range and makes the vehicle unreliable for normal use. I reported this issue to Tesla on March 6, but the earliest service appointment available to me is March 17 at the Tesla service center in Fayetteville, Georgia. Because Tesla service centers are not widely available, I must travel to another city to have the vehicle inspected. The limited battery charge creates a difficult situation because I must determine how to get the vehicle safely to the service center with very restricted range. I may have to arrange towing or attempt to drive a vehicle that cannot fully charge. This issue has also created a hardship for my household. I have a toddler and normal daily responsibilities, including errands and transportation needs, but the vehicle cannot reliably be used due to the charging limitation. Being without dependable transportation for an extended period of time places families like mine in a very difficult position. This problem appears to be related to the vehicle’s battery management system and is not the result of driver misuse. Consumers should not be placed in situations where a major battery fault leaves them with limited transportation options while waiting extended periods for service, especially when service centers are not easily accessible.

Vehicle will suddenly apply brakes while using standard cruise control for no apparent reason. This is extremely dangerous as it has almost caused several accidents on the highway. I have almost been rear-ended several times. This is a very common problem and well documented problem referred to as "phantom braking" on Teslas and something needs to be done immediately.

Both torn bushing and broken links at 29k miles.

The upper control arm bolt came loose on its own.

Vehicle experienced front suspension lateral link failure. The links separated from the sub-frame due to improperly secured fasteners. This is the exact defect described in existing recall SB-21-31-003 / NHTSA Campaign 21V835000. The existing recall states 'front suspension lateral link fasteners may loosen, allowing the lateral link to separate from the sub-frame.' This vehicle has this identical manufacturing defect but was not included in the recall database. Tesla Service confirmed the links 'fell out' and separated from the sub-frame at approximately 65,000 miles. Technician notes indicate a 'speed mismatch between wheel and motor' caused by the link separation - this is the symptom of the underlying fastener defect. The failure resulted in loss of steering control and made the vehicle undriveable (VOR - Vehicle Off Road). This is a safety-critical manufacturing defect affecting front suspension, creating crash risk due to sudden loss of vehicle stability and control. Owner is being charged for repair of a known manufacturing defect that should have been covered under the existing recall. This suggests the recall scope was too narrow and did not capture all affected vehicles with this defect. Request investigation into whether recall should be expanded to include additional affected vehicles.

The car suddenly reduced lane assistance and steering assistance functionality. After calling Tesla they said it is not a software issue. I checked the service mode and it indicated a malfunction in the steering assist motor, which apparently costs $3500 to replace. Online, I have found many complaints about this problem that are not resolved by software updates. In addition, there was a large number used steering assist motors for sale online which indicates a more wide spread problem. This is not normal for cars to have this failure prematurely and is a serious safety hazard. I read online that some had their steering EPAS get locked while driving on the highway and nearly destroyed their Teslas

Lower front control arms are bad. Was told by tire company they need replaced. Quote about 2k

When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.

There is a rip in the lower control bushing making steering difficult to control. I see that this is a common issue but no recall yet. My car has only 28k miles.

My heat pump and ac unit went out and Tesla wants me to pay $4000 for a faulty part that broke in less then 3 years

Picked up car from tesla service on 12/30/2025. On [XXX] at around [XXX] I had pressed the car break and suddenly accelerated and lead to crashing into the pole. I am concerned about the safety and if it is drivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Monday 12/29/2025, while driving my 2021 Tesla Model Y on the highway at approximately 70 mph returning from DTW Airport to my home with my children in the vehicle, the steering suddenly locked / the steering wheel would not turn. I was able to pull over to the shoulder. There were no warning lamps or warning messages displayed before or during the failure. After pulling over, I powered the vehicle off and back on. The steering partially worked again, and I was able to drive home. Later the same day at my friend’s house/driveway, the steering locked out again and this time it was completely locked, making the vehicle not safely drivable. Again, there were no warning messages or symptoms prior to the lockout. Tesla Service provided a written estimate documenting the complaint “steering locked out / cannot drive” and proposed replacing the steering gear/steering rack (“Steering Gear LHD,” part number 1188832-00-B) plus alignment, total about $3,127.70, at 96,042 miles. The vehicle and component are available for inspection upon request (Tesla can retain the replaced part). This is a safety defect concern because sudden loss of steering control on a highway without warning could lead to a crash, especially with passengers/children in the vehicle.

Frunk (Hood) has been randomly opening at times when the car is parked. Today it opened after being parked at my office parking lot for 3 hours. I am concerned that this can occur while driving, especially on the highway, potentially causing a deadly accident.

Tesla's Full Self Driving (FSD) stopped my car on trolley tracks today, and would have stayed on the tracks for a minute if I hadn't taken control and driven off the tracks. This occurred in downtown San Diego, where the trolley (light rail) has many level street crossings. They are well marked. You are not supposed to enter the zone around the tracks until the vehicle ahead of you has moved far enough for you to be able to cross the tracks and get safely past them. I was using FSD. It drove my Tesla onto the tracks before the car ahead of me had given me room to get off the tracks. The line of traffic was stopped for a red light. I would not have been able to drive forward until the light changed, perhaps over a minute. So, I took over and manually drove the car into the adjacent lane, which luckily was empty, and off the tracks. If a train had come while FSD was still in control, this would have killed me, and perhaps other nearby people. There was no warning message or other indicator.

Received a notice that steering assist may be reduced. Other model year Ys have been recalled due to the same issue. It doesn’t make sense that this should fail in a vehicle that is 5 years old with no accidents and low mileage. This is a safety issue due to manufacturing defect and should be covered under warranty.

I parked my Tesla vehicle in a friend’s driveway. When I returned and opened the driver’s door, I entered the vehicle and attempted to put it into Drive. At that point, the vehicle display went completely blank and the vehicle became inoperable. I then attempted to open the door from inside the vehicle, but the door would not open and I was unable to exit the car. I was effectively locked inside the vehicle. I contacted Tesla customer support and remained on the call for approximately 1.5 hours before receiving assistance. Tesla customer support confirmed that the issue was caused by failure of the 12-volt battery. At the time of the incident, the outside temperature was below 0 degrees centigrade. The incident occurred in Cedar Rapids, Iowa. There was no prior warning or notification from the vehicle or the Tesla mobile app indicating that the 12-volt battery was at risk of failure. The failure resulted in loss of vehicle function and inability to exit the vehicle, creating a serious safety concern.

After charging the vehicle threw error code “BMS_a079 Unable to charge - Maximum charge level reached Reduced maximum charge level - Schedule service”. The car would no longer charge and had to be taken in for service. Tesla advised the High Voltage battery needed to be replaced. Replacing the High Voltage battery resolved the issue.

Left rear passenger seatbelt stopped working. There are no visible issues with the belt, metal plug or receptacle, but for some reason the seatbelt will not engage nor click in to secure the belt onto the passenger. This is a safety issue as my daughter typically sits in this seat and she cannot safely sit there now without a functioning seat belt.

The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

The front suspension on my 2021 Tesla Model Y developed progressive creaking and groaning noises during low-speed turning, especially in parking lots or when maneuvering. The noise began intermittently around 45,000 miles and became much louder by around 86,000 miles, which made me concerned about a potential safety issue before a long family trip. The sound comes from the front lower suspension area and indicates that something may be loose or failing. I am worried about the possibility of losing steering control if the suspension components separate or shift while driving, especially with my children in the car. The Tesla Service Center in Lisle, Illinois inspected the vehicle and informed me that both front lower lateral links and both front lower compliance links must be replaced (all four front suspension links). The repair estimate is about $1,600. This problem appears identical to the condition described in Tesla’s campaign/recall SB-21-31-003 / NHTSA 21V835, which involves improperly torqued front lower lateral link fasteners on 2020–2021 Model Y vehicles. My vehicle shows identical symptoms and identical components, but my VIN does not appear in the recall. I contacted Tesla corporate support by email requesting a safety/goodwill review, but I have not received any response. I believe this issue is safety-related and may indicate that more vehicles should be included in the existing recall. I am attaching the Tesla service diagnosis confirming the required replacement of all four front suspension links.

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12V battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “VCFRONT offline/unable to contact VCFRONT” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12V failure and says the overheating was due to an air pocket in the cooling system, but the VCFRONT messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of VCFRONT/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.

Detailed Description of the Defect: Friday Incident: While picking up my son from school, the vehicle abruptly disabled multiple safety and driver-assist features. The car rolled backward on a slight incline, failed to display any surrounding vehicles on the FSD visualization, and retained accelerator input even after I removed my foot from the pedal. The vehicle continued to speed up slightly in Drive and Reverse without my input. Soft resets did not resolve the issue. Monday Incident (Collision Caused by Malfunction): On Monday morning, the same malfunction occurred. As I reversed into my garage with the door opening, the car again held the accelerator input after I lifted my foot, causing the vehicle to continue moving backward unexpectedly. The vehicle struck my garage door, causing property damage and a dent to the trunk. This was not driver error. It was unexpected propulsion after pedal release — an extremely dangerous condition.

I dropped my kids to school and started reversing the car without seatbelts. Thinking that I will get out of the parking lot and then put the seatbelt on. Car will stop and goes into park mode. Somehow I came out of the parking lot and about to put and drive again same thing. Car will go into park mode. Somehow I started coming out of the parking lot and took a pause. Same thing again car stops and goes into park mode. It was almost the car behind me about to hit. I guess this is a bug of the “Hold” mode.

I am filing this complaint regarding a high-voltage battery defect in my 2021 Tesla Model Y. The vehicle has been diagnosed by Tesla Service, and both the technician and service advisor confirmed that the high-voltage battery has an internal short. This is a critical failure involving the primary energy/storage system of the vehicle. Despite acknowledging the internal failure, Tesla is denying warranty coverage for the battery replacement. They have stated that failure is internal, and is not caused by anything external The failure was not caused by an accident, environmental exposure, or improper use. This appears to be a component-level defect within the 2021 Tesla Model Y battery packs Considering Tesla has issued prior service bulletins for Model Y high-voltage battery quality issues in adjacent model years, this may indicate a broader pattern of battery defects. They are trying to charge people over $12,000 for battery replacements that should be covered by tesla due to poor workmanship and materials used. Many have had to have multiple battery packs replaced.

My 2021 Model Y at 49,865 miles had a safety-critical failure of the "front lower compliance and lateral links." The Tesla technician confirmed it was a "safety issue."

Both rear seat belt buckles (driver-side rear and center) fail to latch securely. The metal tongue inserts fully into the buckle but does not lock with an audible click and releases immediately upon light tension. This prevents the seat belts from restraining passengers in a crash. - No visible debris, damage, or contamination in either buckle. - Issue occurs consistently on multiple attempts and with different seat belt tongues. - Vehicle is 2021 Model Y Long Range with 83,610 miles. - **Problem first noticed yesterday (November 2, 2025)**. - Tesla Service has refused repair under warranty, stating the vehicle is out of warranty, despite this being a critical safety component governed by FMVSS 209. This is a **safety defect**, not normal wear. The rear seat belts are **inoperable**, rendering the rear seating positions **unsafe and non-compliant with federal safety standards**. Similar failures are widely reported by other Model Y owners on NHTSA and Tesla forums. REQUEST: Please investigate this recurring seat belt buckle latching failure in Tesla Model Y vehicles. A recall or safety improvement campaign may be warranted.

On October 2, my Model Y battery was replaced with a defective cell. Tesla service center replaced the battery. The vehicle could not charge or operate, making it unable to be driven. Today, November 2, while driving my car, my Tesla ABS system and other battery components experienced total failure while driving. For a brief period of time, I was unable to brake completely and my vehicle felt like it was skidding. At the time this occurred, my 1 year old daughter and pregnant wife were in the vehicle. This could have been much worse.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at an undisclosed speed, there was a loud clunking sound coming from the rear driver’s side of the vehicle. There was no warning light illuminated. After the failure had occurred, the mechanic who towed the vehicle informed the contact that the failure could be related to a detached axle. The vehicle was towed to the dealer, where it was diagnosed and determined that the front suspension lateral link had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. After researching, the contact discovered NHTSA Campaign Number: 21V835000 (Suspension). The contact expressed concerns that the vehicle should be included in the recall due to the similarities between the reported failure and the recall summary. The approximate failure mileage was 45,483.

The driver rear left side door is unclear electrical control and broke so I cannot open the door from the outside. I have a child inside. This is an extreme safety hazard were an accident to occur.

The contact owns a 2021 Tesla Model Y. The contact stated that while coasting into the garage, the vehicle independently accelerated. No warning light was illuminated. An independent mechanic or dealer was not contacted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. However, the contact was in the process of repairing the vehicle. The manufacturer was not notified of the failure. The approximate failure mileage was 38,727.

I am reporting a safety issue involving my 2021 Tesla Model Y. The vehicle recently displayed a “Parking brake function degraded” warning. The car has only 91,000 miles and is approximately four years old, which is far too soon for a failure of a critical safety component such as the electronic parking brake. Please investigate whether this issue is part of a wider defect affecting Tesla Model Y vehicles. This should not occur on a relatively new car with moderate mileage.

Getting message on screen since october 2025. That time total milage on my car was less then 30,000 STEERING ASSIST REDUCED and LANE DEPARTURE AVOIDANCE FEATURE UNAVAILABLE. I did reset / restart the vehicle / soft / hard reset, software update. and This both message got disappear and then again after sometimes its keep coming back. So i did appointment to rocklin tesla center and they gave me cost estimate $5770. Thats way too much so i decline but they said those message might keep popping up because of LOW VOLTAGE DISTRIBUTION AND CONTROLLERS. So i accepted that service and paid $359.68. But i am still getting same both messages on my tesla screen. Sometimes it does comes and sometimes it does not. I did online research and people with same problem stating that because of TESLA's poor manufacturing steering wheel and some kind of faulty circuit board causing this issue. My car never been to any accident and its very low on milage. Please look for other tesla owner who has same problem and tesla has to fix this problem without charging this much amount. Thanks

The contact owns a 2021 Tesla Model Y. The contact stated that while the vehicle was parked, the contact observed the code BMSA079 on the computer, and messages "Vehicle Unable to Charge to Maximum Charge Level" and “Maximum Charge Level Reached - Reduced Maximum Charge Levels" were displayed. The vehicle was taken to a dealer, and it was determined that one coil in the battery was inoperative, and the dealer reduced the charge and refused to increase the battery charging level. The manufacturer was notified of the failure. The failure mileage was 155,000.

🚨 Immediate Escalation: Safety-Related HV Drive-System Concern / Diagnostic Fee Dispute / No Loaner – Urgent Review Needed VIN [XXX] I am requesting immediate escalation of a safety-related concern involving my 2021 Model Y (approx. 90,000 miles) currently assigned to the Tesla Wilmington Service Center. The advisors (Shelly & Amanda) has stated the diagnostic fee will not be covered until after inspection, but the earliest inspection is October 22, and I’m being asked to drop off the vehicle now with no loaner or transportation support. This is a High-Voltage Drive-System concern that may fall under the Drive Unit Limited Warranty (valid through Feb 2029). The local team refuses to classify the case under warranty review or confirm transportation support, leaving me without safe mobility for weeks. Please escalate this to a Corporate Service Manager or HV Warranty Specialist today and confirm: 1. That the diagnostic will be covered pending warranty review, and 2. That loaner or transportation support will be provided. I’ve been going back and forth with the Wilmington team for a week, and this matter has not been resolved. Despite this being a SAFETY concern and issue . I was told that that O would have to wait weeks to get this issue resolved.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving uphill at an undisclosed speed, there was an abnormally loud pop coming from the vehicle. No warning light was illuminated. In addition, the contact stated that the vehicle lost automotive power and rolled away in reverse downhill towards oncoming traffic. The contact was able to avoid oncoming traffic and reverse onto the shoulder of the road; however, the driver’s side rear driver’s door failed to unlatch or open as intended while using the interior door handles. A local tow truck arrived on scene, and the passenger’s side door failed to open as intended with the exterior door handle. The vehicle was towed to a local dealer, where it was diagnosed, and determined that the 12-Volt battery needed to be replaced. The vehicle was repaired but remained at the local dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.

Rear cameras and side cameras suddenly failed resulting in low visibility and severe blind spots increasing the chances of collision with other vehicles, people, etc. It is reproducible at the dealer and they are trying to fix the problem by replacing the computer. It can be inspected until dealer repairs the issue. The vehicle has only been inspected by the dealer. There was a warning on the screen starting that cameras are temporarily unavailable but camera function did not return after a week and brought to the dealer for repair.

I was driving along one of the main highways in Orlando, Florida called [XXX], on Wednesday [XXX], in my Model Y Tesla. I was between the exits of [XXX], and [XXX]. I was in the middle lane. There was a software update issued the previous Sunday. The warning came on the display that the lane changing was not valid. At that point the car took over and accelerated. The brakes would not work, until I slammed on it after 3 times, and the car began to decelerate. The air conditioner went off, along with the electrical turn signals. I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a concrete barrier, and a tree infront of the barrier. The car would not respond to park, neutral or the emergency brake. I tried re-booting the car 3 times and nothing. I had to call a tow truck to tow to the Tesla Service Center in Clermont, Florida. They could not get it in park either and had to drag the Tesla onto the flatbed. After 5 days of not responding to my text, I walked into another Tesla service center to plead my problem. Long story short, there is an unexplained anomaly that is in the CANBUS and cannot duplicate the error. More $ to have to tested for another week. They gave me a loaner to use, a Model S. After a few days driving it the loaner screen went blank and I was stranded. I had their loaner towed back to the service center. They will not 100% address the problem. They know it is in the CANBUS system, but now I definitely am scared to drive the car or get it back. How do I know if they will really tell me it is fixed? I fear if I get back in the car.

This incident appears to relate to NHTSA ongoing investigation at Tesla's low voltage battery system failure causing door handle malfunction. (September 26, 2025) 2021 Model Y front and rear doors (all four) was locked down with a seven years old child inside the car at home garage driveway. Mom unable to open up doors from exterior. A few hours later, left driver door was able to open but other passengers door remained locked down. (October 2, 2025) Sent Model Y to Tesla service center and identified low voltage battery and vehicle controller failure. Tesla technician replaced those electrical components with service fee charged.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the front end of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that the front suspension lateral link fasteners were loosened. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V835000 (Suspension), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 22,000.

Front suspension upper control arm makes loud creaking/squeaking noises when turning at low speeds. This is a known and widespread issue affecting Tesla Model Y and Model 3 vehicles, caused by premature ball joint wear. This poses a safety risk, as the upper control arm is a critical suspension component and could fail while driving, potentially leading to loss of steering control. Tesla has acknowledged the issue through service bulletins, but they do not cover the repair outside the 4yr/50k mile warranty, leaving many owners with the same premature failure. Some repairs may be offered under goodwill, but this is inconsistent and not guaranteed.

Tesla’s Full Self-Driving (FSD) system has repeatedly demonstrated unsafe behavior in my 2021 Model Y (VIN [XXX] , ~60,184 miles). The issues involve Adaptive Cruise Control, Lane Keeping Assistance, and Forward Collision Warning. FSD frequently follows vehicles too closely, leaving insufficient distance. When I disengage, I am left with no safe option: braking hard risks being rear-ended and triggers a hard-braking event, while lifting off the accelerator leaves me dangerously close, still flagged as unsafe following. FSD often waits until less than a mile before highway exits to attempt lane changes, causing last-second darting, missed exits, or unsafe maneuvers. It also performs excessive and unnecessary lane changes that add risk without improving efficiency. Merges are frequently unsafe, forcing me to brake hard to let others pass or accelerate aggressively to avoid being cut off. On several occasions, FSD has jerked or swerved into adjacent lanes without signaling, seemingly triggered by shadows or changes in the road surface. These phantom maneuvers are unpredictable and hazardous. On [XXX] at about [XXX], at a T-shaped intersection, FSD failed to yield to a vehicle traveling straight with the right of way while I was making a left turn. I had to slam on the brakes to disengage, narrowly avoiding a collision. This was the second such incident in the same intersection in one week. These repeated failures—unsafe following, late exit attempts, failed merges, phantom swerves, and failure to yield—create significant risks for me, my passengers, and surrounding drivers. The problem has been reported to Tesla multiple times via in-car voice reports and a written service request, and logs from my vehicle should confirm these events. No warning lamps or system alerts appeared before or during the failures. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
