Scary thing happened today. While my wife and I driving our Model Y to Ikea, a message showed up on the screen telling us to pull over the vehicle is shutting down. After we pulled over to the shoulder, the car wouldn't start with the message saying it was shutting down. The car never really shut down but I could not put it back to Drive. After resetting it twice, we still couldn't start it. I then contacted roadside assistant for a tow truck to the SC. It was going to be a 45 min wait. After 15 min the shutting down messages went away and I was able to drive it again. I canceled road side assistant and was able to continue our trip. The rest of the day the car drove fine. I still made an appointment with Tesla for next week to see what is wrong with it. Have this happen to anyone else? Getting stuck on the highway was no fun, especially we were at a curvy part of the highway. Fortunately the shoulder of that section was pretty wide. Never going to buy another early version of Tesla again. Been having too many small issues, and today experience actually made my wife to lose a lot of faith in the car.
