NHTSA Complaint #11622852 — 2023 TESLA MODEL 3

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to brake, the system did not function properly, suggesting a potential mechanical or software defect in the braking and/or safety alert systems. Aftermath: •My vehicle sustained considerable damage. •I now feel unsafe driving the vehicle, particularly on highways, as I am concerned the brake failure could recur. Request for Investigation: Given the severity of this issue, I am seeking an investigation to determine: 1.Whether there is a defect in Tesla Model 3 braking systems that could result in brake failure under normal driving conditions. 2.If there is an issue with the vehicle’s safety features failing to activate appropriately. This incident has raised significant concerns regarding my safety and that of other drivers, especially given the car’s relatively new condition and low mileage. I would appreciate a prompt investigation into these safety concerns.
