2021 TESLA MODEL Y Complaints

The contact owns a 2021 Tesla Model Y. The contact stated that while her husband was driving approximately 75 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle inadvertently slowed down to 30 MPH. The contact disengaged the cruise control and the self-driving feature also disengaged simultaneously. The manufacturer was made aware of the failure. The Service Center diagnosed the vehicle with a software failure however, there was no current fix. The failure mileage was 10,043.

Traveling at 80 MPH using autopilot on an open freeway when suddenly a phantom braking event occurred and slows us down to 50 MPH in 5 seconds. There were no objects on the freeway and the closest car in our lane was at least one mile in front of us.

During a drive on 09/06/222 the car had 3 instances of phantom emergency braking while using autopilot. All the times there were no cars around the Tesla, the stop was a hard brake that jerked passengers around as well as shifting cargo. This has happened periodically before but now it is become common on every drive. Two of these instances occurred with in minutes of each other. The other happened later in the drive after stopping to charge. A hard stop like these could cause a serious accident if someone is following to close. These hard brakes could also cause whiplash style injuries, seatbelt abrasions, or bruises to passengers. There were no warnings, messages or sysmptoms prior to the issue.

I was driving my Tesla Model Y using “navigation with autopilot” on 9/4/22, from San Francisco to San Jose. The vehicle suddenly stopped while traveling at high speed after crossing “green” metering light in the ramp from 237 to 880S. The vehicle behind had to make a sudden stop, barely avoiding a rear end collision. This is the 4th time I have experienced this “phantom braking” while traveling at high speed on freeways.

The contact owns a 2021 Tesla Model Y. The contact stated on two separate occasions while idled in a parked position and the brake pedal depressed, he shifted into reverse position and the vehicle inadvertently lunged forward approximately 5ft without acceleration. The vehicle then performed as normal. The contact then stated that on a separate occasion while idled in a parked position and the brake pedal depressed, he shifted into drive without the accelerator pedal depressed and the vehicle lunged forward 15 ft without warning. As a result, the contact crashed into a restaurant window. No warning lights was illuminated. No medical attention was required. A police report was filed. The vehicle was currently being towed to the dealer. The vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.

Frequent, random, phantom braking using cruise control. Informed Tesla with times +/- one minute. Sometimes the braking was very hard and could cause a rear-end collision (at highway speeds). Always occurred with no warning and highly variable conditions (light, or hills, or overpasses, and then apparently nothing). I called Tesla and technician said overpasses were a problem. Vehicle and components have not been checked.

I have experience phantom braking on my Model Y many times when I used FSD(full self drive) on the freeway. The car just randomly slows down / decelerates abruptly even if there are no obstacles or other cars in front. This results in a serious situation when the vehicle behind may ram into you causing a fatal accident. I have always reported this issue using voice control REPORT BUG and got acknowledgement saying THANKS FOR THE FEEDBACK. But I have never heard from Tesla that they have fixed or are fixing it. This is repeated happening every time I use FSD on freeway even as of last week (week of Aug 21, 2022)/

During daylight hours when the autopilot is engaged at normal highway speeds - the Tesla brakes engage and quickly slow down the car. It occurs on long straight roads with no traffic. This appears to be a "phantom braking" issue that is causing my car to suddenly brake for no reason. There are never any cars around when this occurs-- just long clear roads. This can be very dangerous. Last known occurrences were on Aug 13 at 8:30a and 10:29a of this year.

Tesla Autopilot (Adaptive Cruise Control) rarely recognizes parked vehicles or obstructions beside the driving lane (right or left side) based on the display console driving environment display. Bicyclist, pedestrians, and other large roadside obstructions are also rarely recognized. Might explain the recent Tesla collisions with stopped emergency vehicles while in Autopilot mode. Don’t know if Teslas recent elimination of radar sensing made this problem worst or not. This failure to recognize nearby obstructions happens daily.

I had unexpected and sudden braking while using Tesla autopilot while in TAC mode or adaptive cruise control. Not Autopilot that steers and keeps you in the lane and not Full self driving, my car does not have FSD. I had 5 or 6 incidents while heading West on I 10 towards Yuma on I 8. There was no rhyme or obvious reason for the braking. No one in front of me or behind me. The amount of braking over the separate incidents was different each time. On the way back to Tucson it happened another 5 or 6 times.
