Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When I entered my vehicle after it was washed at the Mercedes-Benz service location, I pressed Memory 1 button and the seat returned to my normal position. Without any further input, I started the engine, and the driver's seat automatically moved backward by itself. When I readjusted the seat and shifted into Drive, it continued moving rearward. As the seat moved backward, my feet could no longer reach the brake pedal. At the same time, the car began to move forward, and I lost control of the vehicle, resulting in a collision that damaged the right side doors. …”
