Driving our 2023 Tesla model Y east on [XXX] on [XXX] near Pecos TX. Car suddenly lost power and started hard braking. We were rear ended by a large pick-up truck that was following as we were both traveling approximately 80 miles per hour when this occurred. The car was towed back to Dallas from Big Springs, TX (approximately 280 miles). The car's rear-end damage was such that my Tesla was deemed totaled by the insurance company. This power failure and hard braking had happened to me repeatedly over the last few years. When I spoke to Tesla at the Dallas service center about this issue, they acted as though they had never heard of this happening to anyone. We were both shaken by this accident but other than some soreness the next day we are physically OK. Tesla repair estimate was approximately $22,000. I was forced to buy another car. I had not planned on doing this as my car was fairly new with low mileage. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
