2021 TESLA MODEL 3 Complaints

Major phantom Braking at 70mph on interstate 5, 4 times the brakes slamed on as if yo had done an emergency stop from 70mph to 20mph fortunately we were not rear ended as I had my son and grandchildren in the car. The car was in cruise control on each occurrence I finally had to stop using it for fear of a major accident

Intro: This is a well known problem with Tesla cars. It's referred to as "phantom braking" in the Facebook Tesla groups and is wide spread. Using only cameras since around 2021 for adaptive cruise control, the car will "slam on the brakes" even though the road is completely clear ahead. This can easily cause an accident if there is a car following you. It has occurred several times since I bought the car Jan 2022. - malfunction component adaptive cruise control. yes available for inspection - a rear end collision could occur when the car's brakes are activated so hard that the car decelerates from 70 to 20 in seconds - the problem is well documented - no, no inspection by any entity. Tesla knows the problems exists - no, no warning of any kind

Wide gap on left back side of trunk whenever it’s closed shut. Opens and close fine but it’s not properly closed. Water gets in through the gap and gets in the trunk whenever it rains or I go to the car wash

I was driving west bound on I4 August 12th 2023 at 1236pm at mile marker 45-47. I was in the left hand lane with the cruise control set at 73 mph. all traffic was moving well. there was no car in front of me. there was a car passing me slowly on the right. there was a retaining wall to my left. My car for no reason changed the setting on my cruise control from 73 to 35mph. this caused my husband and I to be thrown forward and I had to jam on the gas to try to regain speed. This was the 4th time this happened and the second time I have reported to Tesla who insists that there is nothing wrong with the car. I am scared if someone is following me closely I will be rear-ended at a high rate of speed. They continue to quote information from the manual and in the invoices insinuating that any incident occurring from this would be my fault. This is a terrifying thing to happen when there is no reason for the car to slow for any reason.

My Tesla Model 3 Phantom Brakes when using Cruise Control, particularly in the morning when the road is clear, no cars or obstacles in front or behind me. The NHTSA KNOWS THIS IS A PROBLEM AND I HAVE PREVIOUSLY MADE THIS COMPLAINT. I contacted Tesla to no avail. They did nothing. WHY HASN'T THE NHTSA DONE ANYTHING ABOUT THIS ISSUE. THIS IS DANGEROUS AS AN ACCIDENT IS WAITING TO HAPPEN.

2021 Tesla Model 3 RWD; 21,000 miles I pulled into a parking spot creeping in like I am about to park the car. When I tapped on the break to stop the car, it suddenly accelerated forward. It jerked so quickly forward that the back of my head was pushed into the headrest like a whiplash. Luckily, there was not a car parked in front of me because I generally park away from other cars. I quickly hit the break and the car stopped. I am 100% positive I did not accidentally hit the gas pedal. If I did hit the gas petal, I would not have hit it hard enough to make the car jerk forward and accelerate like it did especially when in a slow creeping speed to come to a stop to park the car. In 36 yrs of driving I have not had one accident. This was quite a scary.

While the car was parked in a parking lot, I get two notification stating “Sentry mode has turned off due to a sentry system error.” When I checked out the car, the car has completely failed to do any of the computer related task, leaving only the gear, AC, and Bluetooth was working. None of the cameras, GPS, sensors, brightness mode and many others were completely stuck. This continued until the next day. This happened without prior symptoms or warnings. I would have been in deep trouble if I have been driving at the time of the incident. When I took the car to the shop, tesla didn’t update the status for a week. After a week, Tesla told us that the Turbo A, Autopilot main processor chip failed. This caused the autopilot to go on loop. Therefore the whole motherboard needed to be replaced. This happened to a brand new purchased Tesla 2021 standard range. Which cost me $2404.00.

The vehicle was traveling in excess of 75 mph with only the autopilot system enabled. The vehicle brakes engaged by itself enough to squeal the tires and the rear end momentarily broke free from the pavement. I disengaged autopilot and drove for approximately 5 minutes. I reengaged autopilot and approximately 5 minutes later the brakes engaged again. I left autopilot disengaged for the remainder of the trip (~ 4 hrs) There were no other vehicles nearby but the breaking was severe enough that if another vehicle had been behind me, it could have caused a collision. The dealer acknowledges that this unintended breaking does occur on other vehicles. There was no warning that the vehicle would severely brake. The weather was clear with bright sun on route I25 south of Denver.

I am getting less miles than advertised on full charge. Six months ago I was getting 185 miles on full charge now I get 156. The vehicle has a little over 5k miles and 2021. FSD does not work as advertised, fails to turn and it makes sudden turns and stops

The driver's seat automatically adjusts when I get into the car. Normally this is a good thing, right? But when my wife and I both get in the car, and I'm going to drive, the car often assumes my wife is the driver and adjusts the seats to her settings as I'm getting into the car. This is a serious problem that has the potential to injure me. Since I'm tall, and my wife is short, the seat starts moving forward as I get in, and it starts to crush me. It's too hard to get back out, and I'm not always able to select my seat configuration quickly enough. If I happen to be carrying something as I get into the car, then that object usually is compressed between me and the steering wheel. There have been times where I didn't have my legs in fully, and they started to get crushed by the seat pushing them forward into the steering wheel. I've talked to Tesla about this several times. Tesla employees have told me that they hear about this problem regularly, but they don't have a way to fix it. And when I ask how to contact Tesla, they tell me use Twitter. I think Tesla's service department should have a method to communicate customer complaints directly. No one has given me any feedback indicating that they intend to do anything, even though they acknowledge that this is dangerous. I also wonder if it is possible that this might happen while I'm driving! For example, what would happen if the battery on my phone drained? The bluetooth connection would be lost. Would the car then pair to my wife's phone and readjust the seats? Of course, there is a simple fix. Instead of doing the automatic but stupid and dangerous adjustment, it should just ask for my confirmation. And never automatically go into a mode of "let's crush the driver"! I only want a computer to think for me if it's going to reason properly, in every situation, every time. Clearly Tesla didn't think this one through.
