2021 TESLA MODEL Y Complaints

Repeated automatic breaking in the assisted driving mode when the road is clear and there are no other drivers or obstacles. The other day my speed was dropped from 55 to 45 mph. It was fortunate no one was behind me.

I have been having inconsistent behavior from the autopilot system. The vehicle has hit the breaks hard when no obstacle was present. I have not had this problem verified by a dealer/service center. It happens seemingly randomly. There was no warning before the breaking started.

I have 13987 miles on the car. 2 times in 1 month on a 2 way highway that has lane markers on the left side of the road. While using cruise control once and the second time was in auto drive mode going about 60. Hard braking with no notice, good thing no one was right behind me. I took control with no issue but this is really a safety issue. I see others reporting it maybe cars coming toward you. But in one case I was alone no on coming cars. Like I said the road has safety markers that are about 3 ft high.

Driving across the country in Model Y. Passed semi in left lane, and when merging back into right hand lane vehicle applied full brakes dropping the vehicle speed from 80mph to 60mph, right in front of semi. I was forced to take over and accelerate to avoid serious rear end collision. It wasn’t just the one time, vehicle continued to perform aggressive braking actions many times. Autopilot was unusable for majority of trip. Tesla needs to make autopilot able to be disabled, and standard cruise control possible. Tesla vision is not safe, and is a major liability. It’s very clear Tesla vision is an attempt to remove radar to get around supply chain issues, at the cost of consumer safety.

The latest version of Autopilot has very serious phantom braking issues. It will brake hard frequently for no apparent reason. Other times it will slow down, but not braking hard, also for no apparent reason. It will also beep at me frequently when cars are approaching in the opposite lane, again for no apparent reason. In short, the latest version of AP is all but unusable and more importantly is not safe for us b/c of the phantom braking issue. Luckily no car has been close behind me when the hard braking has occurred but it certainly could be and could cause a serious accident.

Using basic Autopilot (adaptive cruise control without auto-steer), the car randomly slams on the brakes putting me at risk of being rear-ended by any vehicles following me.

Vehicle braked suddenly on the exit lane of a highway around noon time, when there was no car ahead of me. There was a large truck passing on the adjacent lane. My car gave a red color warning of imminent collision and braked hard. Fortunately, I avoided having an accident with cars following me by pressing on the gas peddle and moving ahead. Tesla service remotely reviewed and determined that at that time emergency brakes were applied because the car detected an object. Tesla said it could have been a reflection, the sun, or any number of things that could have triggered the false detection causing the vehicle to brake.

The contact owns a 2021 Tesla Model Y. The contact stated while driving at various speeds, the vehicle would brake independently without warning. The contact stated no warning light was illuminated. The vehicle was not taken to a local dealer to be inspected. The manufacturer was not informed of the failure. The failure mileage was approximately 970.

A recent vehicle software update now has a speed limit alert stuck right in the middle of the touch screen display. It's unnecessary, annoying and intrusive. Tesla service said to get rid of the alert I need to TURN OFF the speed limit setting!!! Discouraging us from using the safety features is not an improvement. I recommend the NHTSA reqiure Tesla to locate the alert in another area of the display that will be visable but not distracting and annoying.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at 60 MPH, the lane assist feature operated independently as he attempted to merge into the right lane. Due to the failure, the vehicle pulled back into the left lane which caused the vehicle to spin in a circle and crash into a median. The air bags did not deploy upon impact. The contact was not injured as a result of the accident. A police report was not filed. The vehicle was initially towed to the dealer where he was informed that the vehicle would be towed to an independent body shop for repair. The vehicle had yet to be repaired. The failure mileage was 24,300.
