NHTSA Complaint #11510912 — 2018 TESLA MODEL 3

Our Tesla Model 3 had a failure of LV contactor which engages the HV circuit while driving the car in a 45MPH side road. The car had a sudden shutdown with emergency brakes engaged and the car came to a stop violently. It was providence that there were no vehicles following or car was not being operated in a 75MPH freeway and hence did not end up in a rear collision accident or worse involving an 18 wheeler. We talked to Tesla service and they indicated that such contactor failures occur and the car would typically behave like it did with stopping immediately as per design. I was telling Tesla service that the car should probably move into Neutral mode rather than stopping immediately. I also heard other instances where Tesla has stopped suddenly in the media. I would like Tesla to review their current logic with handling contactor failure and prevent violent and sudden stops of the vehicle to prevent accidents.
