2021 TESLA MODEL Y Complaints

The cruise control and auto pilot functions failed while driving in the rain. The car would not disengage from auto pilot and continually would engage back into auto pilot and eventually locking tires and spinning out across all lanes of the freeway. My safety and all the drivers around me are put at risk when something that dramatic occurs. The car spun out completely out of control and after doing a complete spin the car continued to spin losing all control and ended up inches from the center median and was facing oncoming traffic. Unknown- I instantly called tesla and removed my memory stick from the vehicle, they are still conducting their "investigation". Took it into the dealer and had them look into the issue. They are currently remotely working on what caused the issue with their engineers. No warning lamps or messages appeared prior to the occurence.

While driving on ice and snow covered roads the regenerative braking feature comes in so strongly that it makes driving dangerous as the car loses traction and control every time the foot is removed from the accelerator. The regenerative braking automatically applies once the foot is removed from the accelerator. Tesla used to have an option to reduce the strength of the regenerative braking but removed that option in October of 2021. That change in software has made the vehicle unsafe to drive on slick roads. I was able to maintain control of the vehicle because of my driving skill, but did lose control numerous times during a 50 mile trip because of the increased regenerative braking feature. Tesla vehicles manufactured before October 2021 still have the option to reduce regenerative braking power, I also own one of those vehicles. I have attached a photo of that screen that shows the option.

Several times now the car has done a phantom braking event where the car brakes for no reason when using adaptive cruise control on two lane highways. Mostly it's when large vehicles like a semi truck or RV passes in the other lane. Sometimes it appears to be due to shadows like overpasses or trees. The car slows down so quickly sometimes that if someone were following me it may cause a rear end collision. Most of the time the slowdown happened without warning. I have submitted a service ticket with Tesla about this but this seems to be a systemic problem on the TMC forums: https://teslamotorsclub.com/tmc/threads/phantom-braking-in-my-new-model-y.253378/#post-6301315 https://teslamotorsclub.com/tmc/threads/phantom-braking-and-active-safety-features.248184/ https://teslamotorsclub.com/tmc/threads/possible-to-deactivate-tacc-and-use-regular-dumb-cruise-control-phantom-braking-unexpected-slowdowns.235813/ https://teslamotorsclub.com/tmc/threads/27-phantom-brake-in-10-miles-how-often-should-i-press-camera-button-to-report-10-6-1-fsd.250396/

Last year Tesla switched to a heat pump system for heating the interior of the car. Since that change the 2021 models are regularly loosing heat when the temperature gets below zero. Sometimes restarting the car will bring it back but not always. This can lead to drivers being stranded with no heat in potential dangerous temperatures. Tesla was aware of the issue last winter and it has still not been addressed and the issue is persisting in newly built cars.

The car's adaptive cruise control system will suddenly and dangerously brake in random situations on multiple occasions. It presents a very dangerous condition should there be cars behind that can't brake in time

The heat stops working when the ambient temperature reaches 0 degrees. This is a safety risk in cold temperatures, especially for young children that can’t wear coats in the car due to car seats. This has happened in newer models that have a heat pump as the heating system, per social media accounts. The service center is inspecting tomorrow. A warning message appears when the heat stops working on the car screen. There is also an error on the phone app when preconditioning cannot start (preconditioning is supposed to mitigate the error, but it gets too cold to precondition).

Heat stops working when it gets to cold. Windows can fog up and make visibility almost impossible. Unsafe as well for passengers in freezing temps. No news or update from Tesla

I was driving from Bend Or to Boise Id on January 1st 2022. The temperature was about 7 degrees out that evening and the heater stopped working. We bundled up and kept the blower on the windshield so that we could see, but by the time we reached Boise it was 22 degrees inside the car. We were very cold. Due to the remote area we were in we did not want to stop.

I was driving on interstate 285 Atlanta in rain. All of a sudden the screen froze. Wipers won’t work. Had poor visibility. Could not even put on emergency lights. Had to do hard reset and pull over. Before I could get them to work again. This was extremely dangerous in the middle of the road. Similar issue happened with my wife in a brand new model 3 a few weeks ago and we were told it was a software issue and resolved with an over the air update. I have the UpToDate software in my model y. Feel Tesla softwares should be approved by NHTSA before being sent to customers.

the new user-interface design removed the defroster icon from the home screen. the driver now has to swipe up on climate controls then select the defroster. this is significantly unsafe, especially when you are having difficulty seeing due to unexpected fog. recommend they add the defroster icon to the home screen.
