“One mile from home the smart brake system malfunction & front radar system malfunction was displayed. Car was shaking and acting as if the emergency brake was active while the car was in motion. Car was slow to accelerate. Had I been on the interstate I could have been rear-ended. Pulled over to turn the car off and back on. Car was okay the remainder of my 20 mile drive.”

“I was driving on the interstate and the TPMS warning came on. I pull off the interstate and park.

There is metal pining and groaning as it cools down, the tire is warm, but not as hot as the center a the wheel. The left rear wheel is cool to the touch, as are the front wheels. I toggle the electronic parking brake a few times and after the wheel has cooled down I drive on. …”
