2021 TESLA MODEL Y Complaints

Experienced phantom braking twice today on I 5. Almost crashed or got rear ended. Car was on auto pilot. This needs to be fixed

SYSTEM MALFUNCTION: Emergency braking ("phantom braking") while set to automated driving/adaptive cruise control. OUR SAFETY PUT AT RISK: On a 2,000 mi. road trip from Denver CO to Tucson, AZ and back, the vehicle slammed on the brakes at 75-80 mph speeds over two dozen times. All incidents occurred either driving south on I-25 or west on I-10 going to Tucson, or on I-10 east and I-25 north on our return. By far the most dangerous event occurred when we were driving east on I-10 in SE Arizona on our return to Denver on 29 January. Driving in the right lane at 75 mph on a perfectly clear day with excellent road conditions, the vehicle suddenly slammed on its brakes. Following closely behind us was a semi-tractor-trailer, that also slammed on its brakes, blasted its horn, and very nearly rear-ended us. The truck driver then followed us at very close range for the next ten miles, If we slowed down, the truck slowed down. If we speeded up, the truck speeded up. We disengaged cruise control so we wouldn't involuntarily brake hard once more. Finally, the truck drive honked once more and dropped back as we sped up. In our view, this was an evident case of road rage on the trucker's part that might have ended tragically. REPRODUCTION OF PROBLEM: We have a 2/27/23 appointment with a Tesla service center here in Colorado to check out the automated driving/cruise control/camera and sensing system. However, this problem only arose under quite specific topographical, and road surface/light conditions on I-25 and I-10 in rural areas, so I'm doubtful Tesla service techs would be able to replicate the conditions. WARNINGS: There were no warnings emitted by the vehicle either audibly or visually (on the display screen) prior to any of these incidents.

While driving on the highway at 70mph, on two separate occasions while using autopilot and cruise control, the car suddenly braked for no apparent reason. There were no vehicles immediately behind me at the time, however this was terrifying because I was scared that I was going to be rear ended at a high speed. I can no longer trust this safety system due it has happened twice randomly now.

The car brakes at highway speed with no safety hazards in sight. This phantom braking occurs while on cruise control or when using the accelerator pedal. We don't use auto pilot. It is very upsetting and could cause a rear-ending accident.

I would like to report a safety issue with the Tesla Model Y 2021 about its "phantom braking" behavior in FSD-Beta mode. While driving on I-94 E, I was overtaking a Semi trailer, when suddenly the brakes were deployed and the the speed went from 76 MPH to 63 MPH in the blink of an eye. I was very fortunate that no other car was trailing behind me which would have caused a disastrous accident. 

Tesla Y Unintended Acceleration! Driving my Tesla I got a phone call that did not show up on screen then 1-3 seconds later my car took control of itself and rapidly accelerated. I had NO control with no steering or brakes. Powerless inside an accelerating vehicle! The car then crashed up on the median through a private community light post and into a tree. The car did not stop until the battery was severed and destroyed by the tree. All airbags went off and all glass shattered. There was no prior warning at all. Insurance adjuster deemed the car a complete total; not worth repair.

Rear doors are stuck and locked shut, the known defect is on youtube with experts explaining this safety flaw where the door handles get stuck and locked and now TESLA REFUSING TO SERVICE.

While driving on cruise control, the car slammed on the brakes out of nowhere. It was terrifying and we were almost hit from behind. There was absolutely no obstruction or any reason for the car to slam on the brakes. We do not feel safe having our young children in the car. We have notified tesla of the issue many times and they refuse to fix it. This car is unsafe and someone, a Tesla driver or members of the public on the road with this car, is going to be killed by the phantom braking . What is the NHTSA waiting for? Please force a recall. Clearly Tesla doesn’t care.

I was driving on a large, multi-lane, divided freeway (5 south Interstate just before Anaheim, CA in Orange County, California) and using adaptive cruise control (not autopilot) to maintain my speed in the mid 70s MPH. It was around 9pm PT and there was very light traffic. The next car in front of me was at least 100 feet ahead of me and there weren't any cars on the left or right of me. All of a sudden the car started decelerating really quickly, and by the time I pressed the accelerator to counteract the deceleration, the car was at roughly 60 MPH. There wasn't any indication as to why the car decelerated so suddenly, and there wasn't anything that I could see that might have caused the cruise control to react that way. Thankfully there wasn't a car close behind me - if there had been, it's possible that the trailing car could have hit me and caused an accident at high speeds. I've read online that there are quite a lot of reports of "Phantom braking" from Teslas, and from the descriptions I've read, my experience seems to be exactly the same. I hope that NHTSA and Tesla can work together to get to the bottom of this and prevent these types of scary incidents from ever happening again.

Heatpump failed which caused a lack of cabin heat and in warmer weather would have caused charging issues due to lack of cooling possibly leaving me stranded. This had a warning on screen about loss of cabin conditioning. This happened over a mountain pass and caused the cabin temp to drop to 25F with two kids in car seats. This could be a really bad situation, luckily we had blankets and such to keep warm for the last few hours of the drive. I believe this was caused by an earlier TSB with sensor replacements and a software change done earlier in the life of my car for heatpump issues. This most likely caused wear on the pump and caused it to fail prematurely just out of warranty. The system was replaced by Tesla at significant cost and confirmed metal shavings in the system from the heatpump. I requested to keep the parts and still have them if further investigation is necessary.
