   When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.

   The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

   I am reporting a safety issue involving my 2021 Tesla Model Y. The vehicle recently displayed a “Parking brake function degraded” warning. The car has only 91,000 miles and is approximately four years old, which is far too soon for a failure of a critical safety component such as the electronic parking brake. Please investigate whether this issue is part of a wider defect affecting Tesla Model Y vehicles. This should not occur on a relatively new car with moderate mileage.

   Alerts regarding vehicle steering, stability, emergency braking, lane control traction, received all at once and the Tesla AI advisor indicated others were reporting the same. No other vehicles in lanes around us showed up on the vehicle LCD screen as normally they do too. Car did not brake normally (foot off accelerator and no braking) and handling seemed different although we were very cautious. Tried to resolve with screen reboot and multiple drives as AI Advisor…

    After a snowstorm, I shoveled my driveway in front of the car which was facing toward the road (the driveway is on an incline, not steep), cleared the snow off the car and then pulled the car forward/put it in park so that I could shovel the rest of the snow. It took me and my 15 year old son 10 or so minutes to clear the snow behind the car. Then I started to salt the driveway behind the car and a snowplow driving by started honking. I looked up and the car was sliding down…
