2021 TESLA MODEL Y Complaints

Computer will suddenly error out and cruise control, AEB, forward collision warnings, and lane keep assist are not available. A warning "cruise control unavailable" shows if you attempt to engage autopilot or FSD. No forward collision warnings, no auto slowing down. Not docked for close following. No visualizations made. Not resolved with soft or hard reboot. Sometimes will randomly will allow to re-engage, other times I have to park the car and let it go to sleep without charging or sentry mode for things to reset. I've driven many, multiple times including for 1.5-2hour segments with a frozen visualization and no AEB or cruise control or FSD. Speed independent, weather independent. Time of day independent.

On 7/18/2023 - my car reported the following: Replace Occupant Classification System (OCS) of Front Passenger Seat. In essence the seat sensor on the car malfunctioned and needed to be replaced. Tesla charged me $466.29 to replace this and said that this was not under warranty, even though this was a safety issue on their part.

On, June 24th and July 15th my vehicle experienced multiple errors while driving. Indicator lights stated the following: stability control disabled, dash cam disabled, traction control disabled, regenerative braking disabled, emergency braking disabled. On July 15th the front motor was disabled, causing the vehicle to not have enough power to continue up the mountain. The vehicle stopped in the middle of the highway, and started rolling backwards. After I was able to turn the vehicle around, the brakes were grinding, and did not stop the vehicle. There as a smell of burnt rubber, and the brake pedal started “ popping” and moving back and forth on its’ own. The engine failure has occurred twice, and all of other errors have occurred 4 times since June 2023. I made an appointment with the Tesla service center and they cancelled my appointment, for no reason. After the July 15th incident, I took the vehicle into the service center myself. These issues are intermittent, which is very dangerous. The car will experience these errors, and then operate as normal. Tesla told me that they thought this entire thing was “ strange” and that they have never heard of this issue. All logs on the vehicle show these errors, and I have a witness. Tesla has not updated me with the status of my repair, or even a diagnosis. I am terrified to drive this vehicle.

My family and I were driving from San Diego to Arizona on Interstate 8. I was utilizing autopilot (adaptive cruise control with lane keeping assistance) and 4 different times the car slammed on the brakes from approximately 75 mph to 60 mph. We were driving on a bright, sunny, extremely hot day (116 degrees). Luckily there were no cars behind us or we could have been rear-ended. It's also noteworthy, there were no cars/vehicles in front of us or objects in the road when the phantom braking occurred. I now no longer feel safe using autopilot on our Model Y. No warning messages appeared and no additional information was provided by the car. We have used autopilot on several other road trips and never experienced this issue.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 65 MPH, the vehicle independently accelerated at high speed. There was no warning light illuminated. The contact desperately depressed the brake pedal, and the vehicle came to a to stop. The dealer was contact, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, and a case was filed. The failure mileage was approximately 42,000.

Yesterday morning I opened the car and put my dogs in the back seat. I closed the door. I then tried to open the driver’s door but the car became unresponsive. I tried to release the charging cable connected to my home charger. The car did not respond via bluetooth or mobile or access card key. The car was completely dead with my dogs inside. I live in Palm Springs. It was 90 degrees and sunny outside. I called Tesla roadside. Towing was dispatched. Eventually the passenger doors opened and I got the dogs out. My car was towed away. Dead. Nobody at Tesla seems to see how dangerous this situation was. It could have been a baby locked inside the car. Tesla has no culture or attitude of taking this seriously or seeing this as a potentially life threatening issue. It’s shocking to me how everyone I spoke with at Tesla saw this as just another glitch or customer trouble ticket. The severity of this issue was completely lost on every Tesla employee I encountered. Tesla must be held accountable. According to the tow truck driver this happens frequently. People are often stranded in extreme heat due to this 12v battery failure. This issue MUST be investigated and Tesla should be forced to respond.

When driving at highway speeds (55 MPH and above), the driver's side rearview mirror vibrates, making it difficult to see and identify back automobiles. This is a safety hazard when exiting the highway or merging the lines when the outside weather is raining/dark/snowing.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? After closing the passenger side door, The 12v battery that controls the Tesla cabin died without any prior warning or car notification that it needed to be replaced, as a result the car instantly powered down , disabling the a/c, windows and door locks and we were unable to open the doors to access the car. 2. How was your safety or the safety of others put at risk? At the time of the event no, just our personal belongings were trapped inside the car but as a parent of a small child I usually put my child in her car seat first and close the door then get in my seat, if this had occurred with my child being in the car , my only option would be to smash in the window to get her out as the car has no back up system to open the car doors if the 12v battery dies. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes , the tesla had to be towed to the service center we’re they had to run system test and replace the 12v battery. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes by Tesla , they ran test and determined that the 12v battery was the issue. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings or notifications were given prior , teslas are suppose to receive a notification to alert the owner the battery needs to be replaced as their cars have a lot of 12v battery drain.

I was driving the speed limit with the adaptive cruise control engaged on I-95 in Maine with no one in front of to the sides of me. All of a sudden without warning my car brakes on the middle of the highway. I regained control right after and did not use the adaptive cruise control for the rest of the drive.

Phantom braking in autopilot. Traveling at 75mph with traffic behind, fortunately the car behind was not following closely. No warning message beforehand, just happened very suddenly with no obstructions in sight. Weather was clear and sunny, no traffic in front. Two minutes later, the car completely ignored a deer standing on the hard shoulder!
