2018 Tesla Model 3 forward collision avoidance problems

While driving, the vehicle suddenly accelerated on its own and began operating without my control. Despite my attempts to steer away from surrounding traffic, the vehicle continued to self‑propel, crossed the median, and entered oncoming lanes, resulting in a head‑on collision with another car.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving at various highway speeds with the Forward Collision Avoidance Adaptive Cruise Control activated, the vehicle experienced phantom braking, causing the vehicle to stop abruptly in the middle of the highway. The contact stated that the failure had occurred on four separate occasions. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided.
