NHTSA Complaint #11522759 — 2023 MAZDA MAZDA3

Automatic emergency braking suddenly engaged while driving on the highway. The car decelerated abruptly to a complete stop, causing the driver behind to rear-end me. There were no vehicles or obstacles in front of the car when the brakes engaged - the closest car was at least 100 feet in front of me. This collision was clearly the result of a faulty automatic emergency braking system. I do not feel safe driving the car knowing this malfunction could happen again, especially at highway speeds. Sudden unexplained braking presents a huge safety hazard to all drivers, increasing the likelihood for collisions and injuries. There were no warnings or symptoms prior to the unexpected brake system activation. After the brakes activated mistakenly, warning beeps and “BRAKE!” message appeared. Car has collision damage and has not yet been inspected by dealer. Police report filed.
