2021 TESLA MODEL Y Complaints

Multiple times on highway car “phantom breaks” when there are no obstacles/cars in front of me. I noticed that the car seems to regularly do this at certain places the highway. For example, on one stretch I’ve had it happen multiple times going under a specific bridge when I’m in cruise control. The car seems to think the speed limit has reduced, leading me to believe the car is reading the overpass speed liMit, not the highway, and adjusting. On another highway, after a steep decline there is an incline. At the end of the decline, the car slams on the breaks as if it thinks the incline in the road is an obstacle.

This car is continually slamming on the brakes when in cruise or autopilot I have reported this to Tesla and tried to have them repair it but they say it’s normal. My 2019 didn’t hav3 this issue. One time I’d did this my wife started to chock on her gum when it slammed the brakes on so hard it dropped about 40mph in a few seconds.

The full self-driving mode in my tesla does not react correctly to speed limit changes in small towns. I will be driving with the FSD at 65 MPH when I get to a small town and the speed limit changes to 45 and then down to 25 for residential area the cars speed does not decrease quickly enough to be at the correct speed limit by the time the car reachs the speed limit sign. Based on the speed limit laws I was taught was the car you are driving and are slowing down you must be at that limit when you reach the speed limit sign or else you can be ticketed for speeding. The Tesla FSD is not in compliance with that specific rule of the road.

While on a 475 mile road trip, my vehicles emergency brake system was activated while using cruise control on more than one occasion with no visible hazard ahead of me. This caused my car to brake at speeds upward of 70 miles per hour on two lanes highways, leaving me to fear that any car behind me could easily rear end me and harm me or my children who were in the backseat. On another occasion during this same trip, the weather began to turn. Snow began to fall heavily leading to poor road conditions. My model y activated corrective steering twice at speeds of 10-20 miles/hr, both times attempting to swerve my car into the lane next to me occupied by a semi truck. These issues are unacceptable and need correcting as they pose a threat to passenger safety.

My 2021 Tesla Model Y has a huge problem with phantom braking. It even occurs when I am only using cruise control. Sudden stops and slow downs. I clearly has problems with large vehicles approaching in adjacent lanes. Not only does it scare the daylights out of my passengers, but it is a major safety issue is someone is following closely behind. The answer I get from Tesla Mobile service is to keep reporting it as a "bug". The answer I get from my Tesla Service center is "what to you expect...Tesla Vision is still in Beta mode". I am selecting a date below because your form requires it, but the problem has been occurring since I took delivery in July of 2021

The adaptive cruise control system is very dangerous due to constant "phantom braking" problems. With cruise control enabled, the car will randomly slow down, sometimes gradually and others times rapidly. Sometimes the deceleration happens when passing a large truck, or a car on the other side of the road. Sometimes it is in response to shadows on the road. Sometimes there is no discernable reason. Instances of rapid and unexpected deceleration make it likely we will be hit by another car or otherwise cause an accident. This problem is prevalent throughout all Model Y cars and detailed online. Dealers say that there is nothing wrong with the vehicle and they hope it can be fixed in the future by software. However, in the meantime, the dangerous situation exists. My vehicle has not been inspected by anyone for this purpose, at least not yet. There are no warning lamps or messages when this happens.

Hello, Tesla has released an update that will turn on the side camera when the blinker is activated. At night, the blinker can blind the camera making it difficult if not impossible to see any object. I'm concerned that this can cause the driver to turn into another car at night. The picture attached is with the hazard lights on and you can see how one camera works correctly and the other has a massive glare.

The heat pump that supplies all heated air to the cabin stopped working completely. Safety was impacted because my windshield fogged up, making it impossible to see clearly out of my windshield or other windows. It was 11°F outside with no heating. I am not sure if a service center has been able to reproduce the issue, but I have images of the fogging and the error message. Nobody has inspected the issue yet. I received an error message "VCFRONT_a447" and "Cabin Climate Control System Requires Service" I have received this error message in two separate occasions now, both when it was lower than 15°F outside.

I have written to you before on my Tesla automatic emergency braking (phantom braking) problem. I am updating you on the issue. Please see the enclosed file.

Sudden acceleration. I was stopped in my driveway (flat surface). The car started to roll forward and I pressed brake hard. Vehicle came to a complete stop but when I removed my foot from brake car lurched forward. Car hit a retaining wall approximately 3 feet away before I could stop it again by braking hard. When the car was put in park I was able to remove my foot from the brake without it lurching forward again. Little personal safety risk in this situation in my driveway with no other people around. the car hit the retaining wall at relatively low speed when it lurched forward.
