NHTSA Complaint #11453141 — 2021 TESLA MODEL Y

My wife and I were driving south on Interstate-93 in NH on Superbowl Sunday. Traffic was heavy and we were traveling about 65 mph when our 2021 Model Y Tesla started beeping and the following message came on the screen - “PULL OVER SAFELY, Vehicle shutting down”. My wife was driving and had just enough time to cross over three lanes to get into the breakdown lane before the car came to a sudden stop. The car did not want to restart. We called the Tesla service center and they were about to order a tow truck but we asked if there was a ‘ctrl/alt/del’ type option. She had us select Safety>Power Off. When our Tesla came back on everything was seemingly normal so the service center said ‘this is very rare’ and that it should be okay to drive. We drove another few miles down 93 and luckily took an early exit ramp because the car shut down again at the bottom of the ramp. My wife and I restarted the car again and managed to limp home in some sort of “Power reduced” mode (i.e. painfully little acceleration). This was potentially a very dangerous situation! Luckily we were able to safely get into the breakdown lane but there wasn’t much time to spare.
