NHTSA complaint: 2024 MERCEDES-BENZ C 300 — FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The vehicle appears to have experienced a braking system malfunction, possibly involving the brake-by-wire system, electronic stability control (ESC), or unintended acceleration event. When the brake pedal was fully depressed, the car suddenly and uncontrollably accelerated forward into a cinder block wall. After the incident, it was observed that only the left-side tires left skid marks, indicating an apparent brake imbalance or failure on the right side. The vehicle is available for inspection upon request. My safety and the safety of others were severely compromised. My daughter and I were in the car during this and are extremely traumatized. Despite pressing the brake pedal, the vehicle accelerated forward and crashed into a cinder block wall, which could have resulted in serious injury or death had a person, pedestrian, or oncoming vehicle been in front. This type of malfunction poses a critical risk of high-speed unintended collisions in public or residential areas. As of now, the problem has not yet been reproduced or confirmed by a dealer or service center, but further inspection is pending. I am requesting a full diagnostic evaluation, including electronic and mechanical systems related to throttle and braking. The vehicle has not yet been inspected by Mercedes-Benz, police, or insurance representatives, but the car is in the possession of a Mercedesâ collision center. NO, there were no warning lamps, messages, or unusual symptoms on the dashboard prior to the
