NHTSA Complaint #11489375 — 2021 TESLA MODEL 3

Traveling between Colorado and Missouri, multiple instances of "phantom braking" where, without warning, the car would brake suddenly and very sharply, such that the tires would squeal and items in the back seat slid onto the floor. There were no obstacles, the weather was clear and there was no reason for it to do so. We were only using the cruise control and not the self driving program. Our safety was put at risk because had a car or truck been behind us, a severe rear end collision could have occurred. We were traveling at highway speeds at the time this occurred. We requested a service appointment but Tesla told us this could not be addressed in a service appointment. Tesla said this would be addressed in future updates. We told Tesla this was unsatisfactory and dangerous. We wanted the car inspected and the problem addressed but Tesla said the service appointment could not do anything. There were no warning lamps, messages or other symptoms before the failure. In fact the braking did not even disengage the cruise control, which normally is the case when the brake is applied. This had occurred previously and Tesla said it would be fixed with a computer update in July 2022. Obviously it has not been fixed.
