NHTSA Complaint #11451049 — 2022 TESLA MODEL 3

This has happened on a couple of different occasions but the one thing that has been the same is it has happened while utilizing the adaptive cruise control system. These incidents come out of nowhere and can be dangerous and cause an accident luckily we have not had that misfortune. While driving on the highway with adaptive cruise control enabled, the vehicle has suddenly and without warning activated the emergency braking. The first time this occurred the assumption was that it must have picked up something on the road because it only lasted for a brief moment, it slowed down the vehicle by 10-15 mph. Throughout this trip, adaptive cruise control was used and it didn't occur in that manner again. What is more alarming are the next couple of incidents which abruptly slowed the vehicle down by 30-35 mph this was very unsettling, luckily no one was behind the vehicle at the time of these incidents. The adaptive cruise control has not been utilized since the last incident which occurred the third weekend of January 2022. The severity and abruptness that the vehicle slowed and I must mention without warning can potentially cause a fatal car accident, especially while driving on the highway. The vehicle has not been inspected or serviced since the incidents and as long as adaptive cruise control is not used there have been no further incidents of this nature.
