2021 TESLA MODEL Y Complaints

While driving on the highway from Ohio to Arizona in December and returning to Ohio in February when using the adaptive cruise control, my car would suddenly and without warning brake and felt as if it would stop if I had not pushed the accelerator. I drove a total of 10 days, and it happened on some days two or three times, once happening five times. Luckily when it happened the traffic was light, but if someone had been behind me, I'm sure there would have been a rear end collision. It caused my wife and me to lurch forward from the sudden deceleration, and our seatbelts kept us from hitting our heads. When I got home, I reported it to Tesla by phone and was told that someone would get back to me. On March 24 I received an email, stating that "this behavior is a known limitation" and "Traffic-Aware Cruise Control may react to vehicles or objects that either do not exist or are not in the lane of travel, causing Model Y to slow down unnecessarily or inappropriately." Tesla did not offer to remedy the problem, saying only that "The braking behavior will improve over time with software updates." Tesla suggested that somehow I did something wrong, when it stated: "When using Autopilot features it is the driver’s responsibility to remain aware and be ready to take corrective action at all times." There was no corrective action to take except for the sudden braking of the car.

I was stopping at the parking lot of my church St. Thomas Syro-Malabar Catholic Forane Church (508 Elizabeth Ave, Somerset, NJ 08873) to drop my daughter. I applied the break but the vehicle kept moving and hit the gas line of the church. The gasline broke and car front got damaged. There was no auto break and warning of the obstacle.

I started having issues with my heat pump and described to the service center that on multiple occasions it has malfunctioned or improperly heated the cabin on both negative temperature and 40° days. I mentioned it also makes a weird noise. Because I mentioned a noise they refused to look at it under warranty and will not look at it unless I pay 87.50. They have a known ongoing issue with what pumps for our model and this should be a priority for them to take care of. It seems like incredibly irresponsible business. This has happened on multiple occasions with tesla they refuse to look at many safety concerns unless I pay. There are also numerous other safety issues with my car they refuse to fix.

I have experienced the now well-documented "phantom braking" problems with my 2021 Tesla model Y. This happens on long trips when I use "Traffic-Aware Cruise Control." The problem seems to occur most often at the crest of a hill, especially if there is a guard rail.

Since buying the car 6/30/21 the automatic emergency braking has activated >300 times not once was it appropriate. We have had the car back to Tesla Service twice to repair the problem with out any improvement. It is only by luck that we have not had an accident. This is not an effective safety feature and it is increasing the likelihood of an accident. If Tesla cannot fix this it should be forced to deactivating the system

For the last few software updates and for a few months the vehicle will phantom brake and apply aggressive stopping in traffic for no reason when using cruise control, autopilot, or full self driving. Instances have occurred which has nearly caused us to be rear-ended by other vehicles. Additionally the car will turn aggressive when using passing lanes. We have experienced instances where the car will turn into a short right turn lane at highway speeds unexpectedly and then require immediate intervention or the brakes will be applied very hard. These situations are repeatable and occur frequently for no reason.

I was driving northbound on Highway 1 on 3-18-22 from Ventura California to Clayton California where I live. Four times through my trip the car suddenly decelerated and the brakes were applied automatically for no reason whatsoever there was no traffic in front of me there were no obstacles in front of me there were no hazards in front of me, it was open road and for whatever reason the car auto braked which immediately reduced my speed to a dangerous condition. If I had been in traffic I would’ve been rear ended!

We've owned this car since delivered in June 2021. Took a trip from AZ to MO in July 2021. When using cruise control, the system occasionally and severely activated the brakes when passing a large vehicle on a four lane divided highway and in some cases no one else was around on the 4 lane divided highway. Auto braking only happened if on cruise control and did not occur if cruise not activated. I mentioned this to a service tech at one of the charging stations in Rolla, MO who indicated it was a known issue and they were working on it. I didn't report it to Tesla thinking it was being handled, but now I see many others reporting it and you dates indicate cars produced prior to April 2021. I'm assuming ours was produced around that time.

Vehicle brakes randomly at highway speeds while utilizing ADAS. Brakes hard and fast without warning.

Have had problems with 'phantom breaking" while using adaptive cruise control (not full Autopilot). This has happened over a dozen times over the last several firmware updates including latest version 22.4.5.16. For no obvious reason, the car just applied the brakes fairly hard (no skids) while at highway speeds without other vehicles nearby or no shadows visible.
