Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“What is happening with my car are the exact symptoms of the known Mazda Recall 6824H - where the Smart Brake Support suddenly engages for no reason and when it does not need to - which has almost caused me to be rear-ended a few times. This has happened at least 7-8 times since I have owned the vehicle. Apparently, my VIN does not fall under the cars that Mazda reports for the Recall, but nonetheless, my car is still malfunctioning as the Recall describes, which is a safety issue for me. …”

NHTSA complaint #11760963, filed 2026-08

“What component or system failed or malfunctioned, and is it available for inspection upon request? The automatic braking turned on while I was accelerating. My car is available for inspection. How was your safety or the safety of others put at risk? I could have been rear ended because my car automatically braked at an unpredictable time in rush hour traffic with someone very close behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? It has happened to me maybe 4 times before but the dealer hasn't been able to reproduce it. …”

“The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an i-ACTIVSENSE Partially Disabled Front Radar Malfunction warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. …”

NHTSA complaint #11703230, filed 2025-12, 38,377 miles

“While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle. When the brake pedal was pressed firmly, there was no normal slowing—only a sliding sensation, as if the wheels locked and the car moved forward on ice. This led to a collision with a stopped vehicle ahead. The following day, the Mazda App displayed a red alert message: “Brake system malfunction. Braking effectiveness may be decreased.” The vehicle’s airbags deployed very forcefully, causing bruising to both driver and passenger, even though the impact was not severe. …”
