2021 TESLA MODEL Y Complaints

At random times, without warning, cruise control changes from set speed (e.g. 70mph) to 45mph and vehicle immediately begins hard braking to achieve new set speed. Any cars following may not be able to react quickly enough to avoid a collision if the driver doesn't react quickly enough to command acceleration back to freeway speed. I sent multiple videos of this happening to Tesla's service department. Tesla virtual service has looked at vehicle's logs and says there's nothing wrong with the vehicle and that it must be in how the vehicle is interpreting fleet data and map data. Clearly a software bug not validating it's input for reasonableness. No audible warning and while the cruise set speed does change on the display, the deceleration happens simultaneously, so no actionable visual warning is given to prevent the uncommanded deceleration and one must react immediately.

Tesla has dog mode, camping mode, and climate on mode, which shows the interior temperature on the screen and in the app. The Telsa was in "dog mode" and displayed on the screen and app that the interior of the car was 66 degrees, but A/C was clearly not on and the interior of the car measured near 100 degrees. If I had not checked on the dogs in the car immediately, they would have died.

The contact owns a 2021 Tesla Model Y. The contact stated that the safety restraint system alert was displayed. The vehicle was taken to the local dealer on several occasions, but vehicle was not diagnosed or repaired. The manufacturer was notified via email but had not responded. The failure mileage was unknown.

My car brakes for no apparent reason when cruis control is active of autopilot. Sometime it is about sometimes it is gradual. In one instance on the interstate at 75mph it took me down to 50 befor I could hit the accelerator petal to make it continue. This is a hazard for drivers around me. I have been in contact with tesla multiple time but they have done nothing to fix it. Lane keep assist is also an issue. When the lane keep assist is turned off in the settings it will still preform the lane keeping. This caught me off guard and caused damage to the vehicle.

The car has less than 300 miles on it and I hear a loud clunk under the front of the floor by the pedals as if something is loose like the front motor or the suspension.

Car started violently shaking at 70mph on the highway, almost lost control of the car and hitting the divider, took it to the tire shop they said could be a balance issue looked harder to realer the foam from inside the tire fell apart 255/40r/20

The contact stated no warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 3,000

What component or system failed or malfunctioned, and is it available for inspection upon request? Adaptive cruise control is unusable on small 2 lane hwy. How was your safety or the safety of others put at risk? Car would brake hard by itself without any obstacle for miles in front of the car. It also brakes randomly following another car or if it detects traffic on the opposite lane. Car would also brake randomly if there was another vehicle behind which almost caused an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Problem was acknowledge by Tesla customer support via the issue reporting app. They downloaded my trip data. However I was told that it wasn't a hardware issue but a software issue. They will issue a fix however it has been 4 months with no fix insight. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No I was told there was no issue with hardware. I have no reported this issue with police or insurance since there was no accident. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamp.

While leaving a parking lot, the vehicle lurched and felt like anti lock brakes kicked in and the car stopped working. The monitor had multiple alerts including saying to get out and back in the vehicle and it may allow me to resume driving. It did not. The vehicle stopped and just would not allow me to drive, pull over or move the car in any way. The park, neutral, drive options were gone. If I were on a highway I most likely would have caused multiple accidents. Extremely scary and not normal. Seems like other tesla forums call this issue out for numerous other people. Something needs to be done.
