2021 TESLA MODEL Y Complaints

High voltage battery systems are failing at an extreme rate on 2021 tesla model 3 and Y. I am a used car dealer and have had 6 battery failures in the last 30 days. When addressing this with the local service center, they said they've reported this to Tesla engineers as they're prematurely failing at "an alarming rate". There is no advanced warnings. The vehicle just leaves you stranded.

I was driving into a parking lot and heard a loud bang. I get out of my car and see that the metal that connects the tire to the car came down and screws came out. It is not drivable. I know this is not something normal and shouldn't happen. This is very dangerous and I am grateful I wasn't on the freeway when it happened. I was not involved in any collision and i did not hit anything. This simply happened on its own

Seat belt does not buckle and stay attached. Tesla is saying that this is not a warranty issue.

Twice, while in full self-driving mode on I-395, my Tesla has made the potentially fatal mistake of trying to turn the vehicle directly into the closed gates of the so-called "hot lanes" (which separate the north and sound bound lanes) and into on-coming highway traffic on those lanes. This is a serious safety issue that must be fixed IMMEDIATELY. This happened most recently on Sunday October 20, 2024, when I was driving south-bound on I-395 with my wife and son in the car. I was in the far left lane with "full self driving" activated. The hot lanes were to our left with all traffic on those lanes driving northbound. The gates to the hot lanes were closed to southbound traffic to prevent someone from driving directly into oncoming traffic. Shortly before we were about to pass those closed gates, the Tesla left indicator light came on and the car began to turn. The map showed the car was trying to turn us directly into the closed gates and oncoming traffic. Fortunately, I was paying close attention to this potential problem because the identical thing had happened previously, during the prior 30 day period when full self-driving was made available for free to all Tesla owners in April 2024. On that weekday evening, I was my driving my son northbound on I-395 after his basketball practice. The hot lanes were running southbound. Once again, as I approached the closed hot lane gates, the left indicator light came on as the car prepared to drive us through the closed gates and into the on-coming hot lane traffic. I am not a Tesla critic. I really like the car, but please address this issue ASAP before somebody gets killed.

This morning when operating on FSD trail version, at tye stop sign I had to make left. This is at intersection of Rueslane and Old bridge Turnpike of East Brunswick, NJ. My car started to make a left when there was an incoming car from the left, and they do.not have to stop. Thank fully the car on the left applied instant brakes and avoided tye accident. FsD failed to make right judgement if left turn was possible or not. Fsd version is v12.3.6

The bushing spontaneously separated from the axle/wheel making the car unsafe and undriveable. I cannot believe I am the only one. This needs to be investigated and the car needs to be recalled

My Tesla still has the phantom braking problem. It is repeatable and consistent. I can tell when it will occur on a route that I drive regularly. Day or night does not seem to alter the occurrence. There is no indication on the touch screen when this occurs. Traffic volume does not matter. It always occurs at the same places so it should be relatively easy to fix if someone would just monitor my computer when it occurs. I regard this as a dangerous problem on the freeway because my car suddenly slows and if the person behind me is not paying attention, I am going to be rear ended. Such a serious fault for a vehicle that performs so well otherwise. Since Tesla does not have a service center in my town no one has offered to look at the problem but since it has been reported so often, I'm not sure they would. I would be happy to demonstrate the problem to a technical person who might be able to diagnose it.

The contact owns a 2021 Tesla Model Y. The contact stated that his wife was driving at 5 -10 MPH and traffic ahead was slowing down, the vehicle in front stopped and the driver depressed the brake pedal however the vehicle then unintendedly accelerated. As a result, the contact crashed into the rear of the vehicle in front. No warning lights were illuminated and no air bags were deployed. No police report was filed due to no injuries being sustained and the insurance company would be handling the incident. The vehicle was towed to a body center where it was diagnosed that the front air bag sensors were fractured in half and failed to activate the air bags but did activate the seat belts during the impact. The vehicle was not repaired, and the repair decision from the insurance company was pending. A dealer was not contacted. The manufacturer was informed of the failure via the app however the contact was still waiting for a return call to speak with a live agent. The failure mileage was 18,680.

I noticed some alignment issues becoming progressively worse with my car. Suddenly in a parking garage my front right tire over rotated and became stuck in the wheel well. I was able to free the wheel and the car said "alighnment issues but car is safe to drive." I drove home with my sister and her baby on the highway. Then I got off the highway and the car did the same thing becoming stuck in the middle of an intersection. I was able to free the car and proceed carefully home. The next morning my front control arm completely broke free and was dragging on the ground leaving the car completely inoperable. I never had any accident or hit any curb with the car. In fact we brought it in 1 year ago to check alignment issues on the same front right suspension. In the shop now the service technician is saying this is a known issue on the MY resulting from not torqueing the bolts enough. I am shocked that the car has not been recalled for this known issues that is a major safety impact. I don't trust this car at all and frankly makes me question the oversight of NHTSA. When I look online apparently many people have been talking about this issue for over a year.

The issue appears to be an acceleration malfunction and brake failure in my 2021 Tesla Model Y. The vehicle is available for inspection upon request. On [XXX] at [XXX], while waiting for the garage door to open, the car experienced an unknown unintended acceleration malfunction, surging forward uncontrollably. It didn't wait for the garage to open, crashed through the garage into the family room, causing significant structural damage to the framing and door. The City of Eastvale declared the house unsafe, sealing it off. I am now homeless and staying with friends temporarily. During the crash, the airbags did not deploy, and the ABS system failed, preventing an emergency stop. The car stopped 4-5 feet away from my wife, who was on the sofa, posing a critical life-threatening situation. Thankfully, [XXX] and I survived, but this incident caused severe mental trauma for my family. We have not reported the incident to Tesla. The dashcam footage appears deleted during the crash and the car seemed to have only recorded footage before the crash and after. This issue has not been reproduced or confirmed by any dealer or service center, but further investigation needs to be done. The vehicle has not been inspected by Tesla or any service center. However, the police and insurance representatives have been involved. We are coordinating further inspections to find the cause of the acceleration and brake failure. We aim to invoke the Tesla Event Data Recorder (EDR) tool to investigate what exactly went wrong with the car. There were no warning lamps, messages, or symptoms before the incident.
