What 2024 Mazda CX-30 owners say
Driver assistance
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. Three days before the incident, the vehicle had a scheduled maintenance and recall service at a Mazda dealer, including a brake inspection and air-bag recall repair. The vehicle was declared a total loss by the insurance company and is currently stored at Copart Hayward, CA. …

The failure also occurred while driving forward into a parking space. The vehicle was taken to the local dealer who was unable to duplicate or determine the cause of the failure. The vehicle was not repaired. The manufacturer was not yet contacted. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 24V649000 (LANE DEPARTURE, EXTERIOR LIGHTING, FORWARD COLLISION AVOIDANCE).

The vehicle intermittently fails to start when pressing the push-button start system. The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition). This has now occurred twice within two years of ownership, indicating a recurring issue rather than an isolated incident. On the most recent occurrence, the vehicle was completely unable to start and required towing. The tow truck operator reported that he had towed four vehicles of the same make/model for the exact same issue within one week, suggesting a broader pattern affecting multiple vehicles. …

The contact rented a 2024 Mazda CX-30.

The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop.

The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. …
