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.

On [XXX], the car was parked at my regular parking garage. The valet entered to the car to bring it down for pick up. After he entered, the power on the vehicle went out and the door would not open. He did not know about the manual door release. I walked up to see what the delay was and found him locked inside. The car was parked on an upper floor and the it was over 100 degrees in the car. We contacted 911 but eventually found the door release. Tesla was notified and towed the car several hours later. They jumped the car to get it open. It seems that the 12V battery had died without warning.

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.
