2022 Tesla Model Y Electrical System Problems

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+

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.

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.

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.

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.

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.

Hello. I brought my Tesla Y to Tesla service local at 7077 W. Sahara Av., Las Vegas, NV. To fix noise in the breaks on Aug 28, 2025, After that on the same day i went to drive Tesla and I started feeling severe ear pressure, heart pressures, severe body pain from high EMF exposure, also severe electric shocks from the floor, seats, back of the seat, wheel, it has been constantly ongoing for already 6 six month since Aug 28, 2025. It’s when ever I am getting inside my car, driving, or just when it’s parked, I feel all that severe pain in the body, severe ear pressure, severe heart pressure, pain in hands, legs from high EMF exposure inside Tesla, also electric shocks from the floor, back of the seat, seat, wheel. My Tesla Y caused severe damaged t my health. I have all those symptoms and pain only when I am inside the car, when I am not in the car, I don’t feel any pain, and I don’t feel all of those severe symptoms and pain in my body. I have this car from 2024, it was perfectly fine, except that during hot season in Vegas, when the temperature is above 80 F, the glass roof got extremely hot, and it burned my head severely despite I cover with sun protector glass roof. But besides that I didn’t have any issues with my Tesla Y. Only after I brought my car to Tesla service on Aug 28. 2025, same day Tesla started causing me severe pain from High EMF and high Voltage causing electric shocks. I contacted local Tesla service many times and tried to address this issues. They didn’t help. I got response from Tesla manager at W. Sahara “ hope it will resolve by itself”:(( no one addressed this issue seriously. I noticed, every time I broght my Tesla Y to local Tesla services here in Las Vegas, the EMF exposure and electric shocks became even more extreme, worst like a 100 times more:(( I honestly after these horrific experience with Local Tesla services I DONT TRUST THOSE TESLA TECHS anymore. PLEASE HELP AND CONDUCT HIGH EMF AND HIGH VOLTAGE INSPECTIONS FOR MY CAR!

On July 22, 2025, at about 6:30 PM in a western suburb of Illinois, on a hot, humid, sunny evening after my car had sat in direct sun all day, my 2022 Tesla Model Y Long Range (Dual Motor AWD) suffered a total electrical failure. As I walked up, the car unlocked automatically with my phone key as usual. I placed my dog in the back seat, closed that door, and immediately tried to open the driver’s/front door—but it would not open. The phone key failed, and the backup key card at the B-pillar also failed to unlock the car. I then tried resetting and reconnecting my phone key through the Tesla app, but nothing worked. There were no 12-V or low-voltage warnings on the display or app. I could not find a phone number or live help in the Tesla app; my son and I searched YouTube for guidance but could not fix it. My dog was trapped inside in dangerous heat, so I called 911. Police first tried a slim-jim tool without success and then broke the driver’s window to reach in and open the front door, but the rear doors and windows remained inoperative. The dog was in the car for 30 to 45 minutes before the window was broken. Once inside, I found that the front seats would not move forward or backward, none of the windows would not roll down, and the rear doors would not open from inside. It took another 30 to clear enough glass to evacuate my 75-lb dog through the front seats; we both sustained cuts, and I sprained my ankle. The event was traumatic and posed a serious heat-injury risk (~85 °F ambient, interior >110 °F within minutes). Police documented the incident. Tesla Service Center (Naperville IL) later confirmed a 12-V failure as the cause, replaced the 12-V battery with an upgraded model under warranty, and repaired the driver’s window and door trim. Tesla Insurance was notified the next morning but closed the claim and covered repairs under warranty. No warnings appeared until the following morning, when a low-voltage alert appeared in my Tesla app when being serviced.

on July 19, 2025 my 10-year old daughter entered the back seat and shut the door. When I (her mother) went to get into the drivers door the electricity in the car completely shut down locking my daughter in the vehicle. There were no visible icons or labels showing where the emergency/manual latch was. She was hystercial and heating up quickly. We called Tesla roadside assistance and the agent spent 10-15 minutes explaining how to get out of a Model 3 (we had a model Y). He then proceeded to tell us that he did not know how to advise her how to get out. He told us not to break the window and to search it on Google. when we asked for his name he would not provide it and he displayed hesitation and resistance to connect us with his superior. We explained that he was dealing with a potentially fatal situation and he displayed ZERO sense of urgency or compassion for the situation. We were able get her out of the vehicle after researching it online. But Tesla did not provide any guidance to help. Our car was at 80% charge and we did not get any low voltage notification or warning that the auxiliary battery was dead or low. My daughter was dehydrated and is forever traumatized by this situation and could have been seriously harmed. Tesla does not provide a standard vehicle delivery process when you purchase or lease a vehicle from them. They do not provide any tutorial or notification on what to do in the case you lose electrical power. The manual emergency latch is not labelled at all. You would never know it was there unless you search online. We sent an email to Tesla notifying them of the situation and they never responded. We even shared this with the service manager who replaced the battery and he said it is a common occurrence and brushed it off.

I saw that the US National Highway Traffic Safety Administration is investigating the Tesla Model Y (2021 and over) due to the electronic door handles becoming inoperative. I am happy and relieved to see this is being looked into since this recently happened to my vehicle a couple of months ago. The rear passenger side door unlocked initially for me to put by [XXX] old into the car seat but when I went to open the driver's side door, the handles would not open. I tried all other door handles and all were locked. Luckily, I had not shut the door next to my child's car seat yet, otherwise it would've locked my child inside the vehicle. I opened a ticket with Tesla and they sent a technician out. He said the low voltage battery needed to be replaced and when this happens all electric door handles will be unresponsive and locked. However, the vehicle never showed any warning or notification leading up to this. He said when the 12V battery fails, the only way to unlock the unresponsive doors is to use the manual release inside the car or jump the 12V battery under the frunk (assuming you have the right jumping cables outside of the car). The Tesla technician said it is a flaw in the Model Y design and he said I would've had to break a window to get my child out if they are not old enough to locate and release the manual door release inside the vehicle. This poses a huge safety risk to parents with young children. I really hope Tesla implements another emergency way to release the doors from outside the vehicle to avoid young children from being locked inside.

The low voltage battery went out after rear right door was opened to put children in car seats. Drove 45 minutes to a train museum with the kids. Everything was working fine on the way down. Once done with the museum and back at the car, opened right rear door to put my younger child in the car seat. My older child decided to enter the car through same door as she didn't want to wait for me to finish to take her to the other side. Once my younger child was buckled up, I closed the door to come over to the other side the buckle in my older child into car seat. The door would not open. The phone application would not get the car to unlock the doors. I could not open any of the doors. Children were trapped inside. My oldest child was not yet buckled and I was able to instruct her to crawl to the front and try opening both doors with the electronic button, which did not work. I then instructed her to use the mechanical door latch vs the electronic and she got the door open. Had it not been for the fact that she was still unbuckled she would not have been able to get to the front to open the doors. I would have needed to call 911 for help getting the kids out as the car was unresponsive.

Our 2022 Tesla Model Y Performance backed out of a driveway into the street and parked in the middle of the street with nobody inside the car, creating a traffic hazard. This happened after around an hour parked. The Smart Summon feature was enabled in the car. Possible cause was that Summon was accidentally activated by phone jostling in pants pocket. Car was looked at by Tesla and found to be in good working order and was considered safe to drive. No explanation of cause of the event was offered by Tesla. We turned off the smart summon feature in the car. Suggest adding an additional step in the Tesla app such as requiring a numerical code input to eliminate the possibility of accidentally summoning the car by random inputs to Tesla app when phone is in a pocket. We have time stamped surveillance video of the event. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
