This happend moments ago. I was on the freeway with autopilot engaged and was about to get on another freeway ramp. I stepped on the brake to take control and the car started veering left and right. Luckily i did not hit any car. It seem to take a while for me to gain some control of the vehicle and has able to park at the side of the free way. When i regained some of my composure i tried to drive again but the car was still veering left and right. Error message is "Traction contol disabled contact tesla service" and "Auto Emergency Braking disabled".i called Tesla road side assistance and the towing company is coming to pick the car up. I'm still shaken up by the experience. Has this happened to anyone?
