The contact owns a 2021 Tesla Model Y. The contact stated that while attempting to park into a parking space at a very slow speed the vehicle suddenly experienced unintended acceleration. The contact indicated that the failure occurred while in a store parking lot and the vehicles speed had increased to approximately 50 mph. During the incident driver lost control of the vehicle and drove down an embankment before the vehicle stopped. No injuries were reported and no police report was taken. The vehicle was towed away. The cause of the failure was not determined. The manufacturer and local dealer were not yet notified. The failure mileage was 600.

This is the 2nd Tesla my mom owned, she drove a model 3 without any problems for many months. She picks up this Model Y on November 19 2020, and drives home from the dealer without issues. Next day November 20, 2020, drives to her work, pulls into a parking spot and came to a complete stop. Approx 5-10 seconds later the car lurches forward, hops over the parking curb, over some grass and into a brick wall at full acceleration. Luckily nobody was hurt, but severe damage to the building and the car. This case of unintended acceleration needs investigation. My mom does not feel safe getting back into this Model Y.
