2021 TESLA MODEL Y Complaints

Repeated random automatic braking while using cruise control at highway speeds. Near miss of rear end collision. Tesla service representative just said to live with it and be careful.

While in cruise control, our 2021 Tesla Model Y (WE DO NOT HAVE AUTO PILOT!) applied the brakes HARD dropping between 10-40 mph with no warning. Cruise control stays active. There were no cars anywhere near us, either in front or in the rear. Over thirty (30) Tesla bug reports were recorded on April 25 and April 26, 2022. While we were not SERIOUSLY hurt, had a vehicle actually been behind us, we would have ended up with a vehicle in our back seat and certainly serious injuries. This same thing happened six months ago on our last road trip. Tesla has blown us off saying that this simply cannot occur. Their response is that the computer cannot slow the car without seeing something. Therefore it must have seen something. This is circular reasoning and is meant to blow off the consumer. This is a serious safety issue. The braking on occasion has been violent. This is similar to the reports in other models. Tesla has twice now, within six months, addressed this issue simply by saying "it cannot occur." Seriously?!

When engaged, Autopilot often causes vehicle to suddenly brake for no apparent reason. Online this phenomenon is often referred to as “phantom braking”.

My 2021 Tesla Model Y, when using adaptive cruise control engages in phantom braking on a perfect clear road with no obstacles. On a recent road trip the vehicle braked suddenly at least 10 times while driving at highway speeds on both divided and single lane roads. This is cleariy unsafe especially if there is a car following. Tesla is aware of this problem and has done nothing to resolve it.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 60 MPH with the cruise control activated, the radar detected a hazard ahead on the roadway and deactivated the cruise control, causing the vehicle to experience phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.

Recently while pulling into my children's school, my car has started deciding that the entrance to the parking garage is a large truck stopped diagonally in front of me and slams on the brakes scaring me and causing everything in the car to go flying. Luckily no one has been behind me while this has happened. I am always entering very slowly, maybe 5 mph at the very fastest.

I was about to park the car in my garage and stopped midway down my driveway to take a phone call. After the phone call, I changed it from park to to drive by stepping on the brake and lightly stepped on the accelerator to ease it into the garage. It quickly accelerated. I stepped on the brake to stop it but it failed to stop. It crashed into my refrigerator in the garage. A video is available for you to view

On 3/7/22- 3/15/22 I and my wife took our Tesla Model Y 2021 for an extensive trip from San Diego, CA to Sedona, AZ. Our Tesla does not equipped with Autopilot. On 3/7 while on I-8 E Arizona, our Tesla was on cruise control at HWY speed, it suddendly braked from 75 miles/hr to 60 miles/hr and slowly going back up without any appearance reasons! There was No cars near and around. Afterward, it happened several more times so we stopped using cruise control on the second day of our trips until return home due to safety concerns of getting hit from behind. I took the Tesla to Tesla service for a check of the issue about a week after return San Diego, and the Tesla technician took the car for a test drive and found nothing wrong!

We were driving roughly 80 mph on an open highway. Clear skies. No cruise control/autopilot engaged. Vehicle slammed on the brakes. Threw both occupants rapidly forward in our seats. Lucky no cars behind us.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 80 MPH, the self-driving feature independently activated and the vehicle decelerated to 50 MPH inadvertently within several seconds. There were no warning lights illuminated. The contact stated that the failure was intermittent. The vehicle was taken to the dealer to be diagnosed; however, the mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 8,480.
