NHTSA Complaint #11525190 — 2016 TESLA MODEL S

On Friday, June 2, 2023, I was traveling at highway speed in the left lane south on Interstate 15 just south of Temecula, California. With no warning my vehicle speed started dropping quickly, and did not respond to pressing the accelerator pedal. I immediately started moving lanes to the right, as my speed quickly decelerated to 30 mph. Luckily, I was able to make it to the shoulder safely. There was an exit up ahead, so I continued to drive as my speed continued to decelerate, in the hopes that I could make the exit and have a safe place in which to stop and contact Tesla service. I was able to make that exit, but by the time I got there my speed had decelerated to 20 mph, and as I continued up the exit to a wider shoulder, the car rolled to a stop and would not move again. The car battery had been fully charged before I left home, and the indicator showed over 180 miles of range available. I contacted Tesla, and followed their instructions to attempt to reboot the car, but was not able to. I then arranged for a tow to the Tesla Service Center in Temecula, where the car is now, and we are awaiting a diagnosis. A similar event happened to us in this vehicle in December of 2022; however, at that time the max speed of the car was able to be maintained at 60 mph, and we were able to make it to our destination safely (10-15 minutes of driving.) Once we arrived at that destination and stopped the car, the car would not restart, and it was towed to a Tesla service center in Burbank, CA where repairs were made. The car has functioned normally until yesterday. I feel this incident definitely put myself, and other drivers at risk. A car suddenly dropping speed to 30 mph on a freeway is very dangerous, and should I have been in a situation where I was not able to change lanes quickly and get off the road, a serious accident could have occurred. A fatal accident re: what seems to be the same issue has been reported involving Terry L. Siegel in Missouri, Feb. 2022
