Hello, We have 46224 miles on the car currently. A couple of weeks back the whole battery died. Tesla replaced the battery and we picked up the car this past Friday, the XXX. After picking up the car the driver's seat does not slide. I looked it up online on the Tesla website as well as on the app and at both the places it was strongly recommended to bring the car back to Tesla as the problem was very very likely secondary to the battery replacement. the seat does not move at all. When I spoke to customer service at out local Tesla dealership in [XXX], the earliest date they could provide us was in the first week of August! This is an urgent issue. We happen to be away on vacation that week. So we were told to review the cost estimate and then find a date on the app to bring the car in. When I questioned the estimate price, I was told that this was the worst case scenario. But the invoice clearly states Calibration, and 3 prices for a switch package all amounting to $364.45 with tax!!! Again I questioned this huge charge, considering the battery replacement and I was told almost rudely, "That does not seem to be the issue." Just not right!!

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.

The rear passenger door was stuck in the closed position and would not open. We brought this to Tesla to fix 5 separate times. My kids sit in the back seat and were not able to get out of the car. We were very worried about their safety because if there was an accident or emergency and they had to get out, they would be stuck inside the car. Each time we brought it to Tesla for repair they "fixed it," only to have the problem occur again weeks to months later. This is a HUGE safety issue. We will attach invoices to this but the dates this occured were 10.3.22, 5.2.23, 6.5.23, 6.21.23, and 4.25.25,

On August 20th, 2025 at 2:50pm, my eight-month-old infant was trapped inside my Tesla Model Y for approximately 30 minutes due to a critical systems failure. The vehicle experienced an error with the 12V battery that rendered the doors, windows, and trunk completely inoperable, preventing any means of access or escape. My infant was flushed, diaphoretic, and crying while stuck in his car seat with an indoor temperature exceeding 104 degrees fahrenheit. Despite all attempts to override the system, the car remained locked, and the battery dead, and emergency services had to be contacted. Officers from the Santa Barbara Sheriff’s Department, California Highway Patrol, and Montecito Fire Department arrived on scene and, in order to rescue my baby, were forced to smash a window to gain entry. The police officer was advised by a Tesla representative to do so, as he confirmed there would be no way to override the system to open the doors. My baby was found screaming in a pool full of sweat and was carried to an ambulance, where the paramedic warned me of concerning vital signs and advised me to go to the Santa Barbara Cottage Hospital to have his condition assessed and treated, if necessary. I have obtained a copy of the police report (Case No. XXX) and will provide it upon request. Tesla confirmed that this problem with the 12V battery is common, nonetheless we were made to pay for a new window and a battery replacement. There were no warning signs leading up to the shutdown and not notifying us of this system failure and the risk involved is complete negligence on behalf of Tesla.

On July 5, 2025, I entered my vehicle parked in my home garage and the door latched shut. Upon putting my foot on the brake. Center screen was blank (did not power on). I attempted to press the unlock button on the door and there was no sound from the motor to open the door. The door was still locked from the inside of the vehicle and I was locked inside. I waited around 5 minutes (after attempting to call my wife to try to let me out of car and tried the open the drivers door again by pressing the exit button. The door unlatched by normally the window rolls down partially to exit. This time the window did not move and I have to force the door open by pressing my shoulder hard against the interior door panel. I hear a popping sound from inside the door and the window would not roll up. I did not drive the vehicle fearing that the car would not start and my family could be trapped inside the car. I created an appointment for Tesla service for July 7, 2025 for the door locks and the driver's window that would not roll up completely and also would roll down but return to a 70% rolled up position automatically. I did received an error warning on the late evening of July 6, 2025 that the 12 volt battery voltage was low on the main center screen of my vehicle. I took the vehicle to Tesla service on July 7, 2025 and it was determined that the 12 volt auxiliary battery that was faulty and my window was repaired and recalibrated. I never saw an alert for the 12 volt auxiliary battery low voltage prior to when I was locked inside the car.

In December 2023 I strapped my [XXX] son into his carseat in our Model Y and walked around to the front to get into the car as well. In those few seconds the 12v car battery died (I did not get any notification in my app) and I was unable to open any doors, so my infant son was trapped. We live in Florida and this was an 80 degree day. With no other recourse I was forced to call 911 to have my son removed from the vehicle.

[XXX] , my [XXX] son, was strapped in his car seat, wide-eyed and confused, as we sat trapped in our Tesla for thirty agonizing minutes. The battery had died without warning, leaving us locked inside our own garage. No power, no way to open the doors. I tried to keep [XXX] calm, singing his favorite songs, but my heart raced as I called for help. A tow truck finally arrived and jumped the car—not enough juice to start the engine, but just enough to unlock the doors. Freedom at last. Tesla’s response? No roadside service; they insisted the car be towed to their service center. Easier said than done—the tow truck couldn’t maneuver it out of the garage. Frustration mounted as I realized I’d have to miss work. Days later, I drove to the service center, where they replaced the battery. But the ordeal wasn’t over. The trim was damaged during the chaos, and now every drive is accompanied by relentless wind noise, a constant reminder of that day. [XXX] still talks about being “stuck in the car,” and I can’t help but feel let down by a system that left us stranded.

“Front passenger Safety restraint system fault, service required” RCM2_a636 message keeps appearing on the screen. It happened right after I bought the car, so I took it to Tesla to fix. It went away for a few months and now it’s back again. According to Tesla, this fault, “ Based on the airbag system's self-diagnostic checks, a persistent fault has been detected in one or more safety restraint components. This could involve seat belts, impact sensors, occupant sensors, or related safety components. • If the airbag warning indicator stays on, the vehicle should not be driven until inspected. • Recurring faults require immediate Tesla service attention. • Pre-tensioner or sensor damage can compromise proper seat belt functionality.” This is a serious safety issue that should be addressed in a recall as it could jeopardize occupant safety of the seat belts or air bags do not work. It also appears to be somewhat widespread and persistent. Tesla also does not appear to have a permanent fix as the first time I took it in they made a comment about one repair already having been done on this before I got the car as a certified used one from Tesla.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The 12V battery failed unexpectedly, causing a complete shutdown of the vehicle. The car became fully inoperable—doors, windows, touchscreen, and manual override systems were unresponsive. Yes, the vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? My young child was inside the car at the time of the failure. Due to the system lockout, I was unable to open the doors or remove them from the vehicle. Emergency responders were called and had to break windows to safely extract my child. This situation posed a serious risk of heat exposure, panic, and injury. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The failure has been documented and attributed to a dead 12V battery, though Tesla has not formally inspected the vehicle as of this writing. I am working to have it evaluated by a qualified technician to confirm the cause. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was not inspected by Tesla at the time of the incident. Emergency responders did assess the situation on site. I plan to notify my insurance provider, and will make the vehicle available for inspection. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No. There were no alerts, notifications, or warning lights indicating the 12V battery was low or nearing failure. The malfunction occurred without warning.

I have a notice that a sensor went out in my passenger seat. I took it into Tesla to get a quote to repay rid and was quoted $2,000 to fix it. When I asked why it is so expensive I was told it is be cause Tesla has to retrofit my car to fit the new sensors because they stopped making my years sensors, my car is only a 2021. This is safety issue that should be a recall, I have several other friends that own teslas that have had the same issue. The sensor that is not working properly is the sensor that registers if a passenger is in the seat or not determining if the airbag needs to deploy when in an accident. so without a working sensor it puts the passenger at risk. This is something I believe Tesla should covering as it is a safety issue & as a consumer I shouldn't have to pay over the fact they discontinued the proper sensor for my vehicle putting anyone that sits in my passenger seat at risk for the airbag to not deploy in the case of an accident.

On [XXX] my husband was taking our [XXX] son to the grocery store and put him in his car seat. He then shut the door and went to open the driver door and the car had locked and would not unlock leaving our [XXX] trapped in the car. We called Tesla immediately and they said the 12 volt battery had died and we needed to call 911. Luckily while I was on the phone with 911, one of the windows was slightly cracked and my husband was able to get the window down further so we could get our son out. You are suppose to receive 3 warning messages from Tesla saying the 12 volt battery needs to be replaced or is dying we did not receive a single one. This is life threatening and extremely dangerous. Our friends who had heard our story just sent us a news story that this happened to a grandmother and her grandchild recently in Arizona too.
