2021 TESLA MODEL Y Complaints

WHILE DRIVING IN AUTO PILOT ON HIGHWAYS, NOT FREEWAYS, THE CAR WILL SUDDENLY BRAKE WHEN IT SEES A CAR ON THE SIDE ROAD THAT IS NOT COMING INTO TRAFFIC. THE BRAKING IS VERY SUDDEN AND HARSH. THROWING DRIVER AND PASSENGERS FORWARD. I WILL NOT USE THIS FEATURE BECAUSE I FEEL IT IS UNSAFE TO USE. PLEASE MAKE TESLA MAKE CHANGES.

Phantom braking when adaptive cruise control engaged. More extreme braking occurs when oncoming traffic approaches from uphill or oncoming vehicle is large (e.g. box truck or semi tractor). Also occurs when large objects appear well off the right side of the road.

While adaptive cruise control is enabled, the car will hard brake at random. The screen doesn't indicate why the car is randomly braking, not are there any other indicators as why or when this will happen. This occurs most often while going around corners, up hills, or when traffic is oncoming in the other lane. This happens on standard roads and highways - although highways are a little better as long as the opposite bound lane is separated by a wide median. Contacted Tesla support December 16, 2021 in which their reply was that "the car is learning... apply constant pressure to pedal in order to override braking system". I did try that for a couple of months, and instead of hard braking, it is a little gentler, but then I run the risk of going over the speed limit as constant pressure has to be applied ontop of whatever the cruise control is set to. Not too mention this defeats the purpose of having cruise control.

The main instrument cluster / screen turns off without notice while the car is in motion. This results in the loss of all displays and controls, such as 1. Speedometer 2. Defrost control 3. Turn signal noise 4. Windshield wiper setting 5. Battery capacity gauge and many more.

My Tesla Model Y has terrible Phantom Braking problems. The AutoPilot features on the Tesla is extremely dangerous. Phantom Braking can happened anytime whenever AutoPilot feature is used, it just suddenly slow the vehicle without warning, there’s no other vehicle in front of me. The problem occurred more on a less busy freeway/ highway, sometimes it’s totally useless because the the feature is too dangerous. On a two lane highway, when more car detect a larger vehicle on the opposite lane, it started slowing down, sometimes that’s very dangerous because cars behind me almost hit my car. Tesla’s AutoPilot is extremely dangerous, they should recall the car and fix the problem.

My wife and I were driving south on Interstate-93 in NH on Superbowl Sunday. Traffic was heavy and we were traveling about 65 mph when our 2021 Model Y Tesla started beeping and the following message came on the screen - “PULL OVER SAFELY, Vehicle shutting down”. My wife was driving and had just enough time to cross over three lanes to get into the breakdown lane before the car came to a sudden stop. The car did not want to restart. We called the Tesla service center and they were about to order a tow truck but we asked if there was a ‘ctrl/alt/del’ type option. She had us select Safety>Power Off. When our Tesla came back on everything was seemingly normal so the service center said ‘this is very rare’ and that it should be okay to drive. We drove another few miles down 93 and luckily took an early exit ramp because the car shut down again at the bottom of the ramp. My wife and I restarted the car again and managed to limp home in some sort of “Power reduced” mode (i.e. painfully little acceleration). This was potentially a very dangerous situation! Luckily we were able to safely get into the breakdown lane but there wasn’t much time to spare.

When car was in "traffic aware cruise control" on open highway it has multiple times unexpectedly braked hard when there were no vehicles or objects in front of it. Once there was a car behind me so I had to accelerate hard to avoid being rear ended. Once it may have been reacting to an oncoming truck in the opposite lane.

While using the adaptive cruise control on the highway, the car abruptly slowed down from approximately 70 mph to less than 55 within a few seconds before I was able to push the gas petal and reaccelerate. This has happened 3 other times in the last several weeks and I am now afraid to use the cruise control. Whereas no accident occurred, if it happened when another car was following me closely, it could have easily resulted in a crash. Each time this has happened, there were no other cars nearby so I don’t know what the car ‘saw’ and was reacting to. The date entered below for the incident is the most recent occurrence.

Phantom braking. I have had numerous incidents of phantom braking, and can reproduce the problem at will on a particular stretch of road. It happens regularly on city streets, occasionally on Interstate highways. It is sufficiently unreliable as to be worthless. I reported the problem to Tesla online in a service request, and was told that the problem will be or has been solved with software.

While I’m adaptive cruise control or Autopilot the vehicle has phantom braking which occurs. Vehicle will slam on the brakes for no apparent reason.
