What 22 owners told NHTSA about the 2023 Mazda Cx-30

While driving down the road a vehicle in front of me braked to stop for a bus loading kids, as I stepped on the brakes nothing happened and the vehicle surged forward. After the accident I viewed the vehicles onboard system status and it had logged several errors including errors to the activsense driver assist control. I used the vehicle’s emergency assist button and contacted 911, and reported the incident to ride share and contact my spouse. Police report lists the wrong time and vehicle but does have the correct vin number

My brakes failed at a stop light. I was waiting at a red light waiting to get on the freeway . Brake was completely pressed, when my car started rolling forward. I kept trying to apply more force to brakes but was unable to stop the vehicle until it rolled into the car in front of me. I then had my car towed to Mazda and was told my accident was a result of human error. Inspection was done and no results were found. If my brakes had failed at any other moment my accident could have been deadly. There is a brake recall for my year make and model but my vin number is not yet apart of that recall. My car was barely a year since purchase I am the first owner .

I have been the owner of a 2023 Mazda CX-30 since July 2023. On [XXX], 2023, I received automated warnings on the dashboard and through the Mazda App stating, "ActiveSense system malfunction. ActiveSense advanced safety and driver support system may not operate correctly." The service department at the dealership where I purchased the car explained that the sensors had overheated due to the hot weather. Unfortunately, a similar warning appeared on the dashboard on [XXX], and this time it resulted in damage to the car. On that day at 13:33, while maneuvering into a parking spot in the parking garage with my foot on the brake pedal, the car suddenly and rapidly accelerated and collided with a concrete post. Fortunately, I am unharmed but shaken, and the front of the car sustained damage. Immediately after the incident, I contacted the service department, explained the situation, and requested an emergency service to assess the car. The service department conducted checks on the brakes and suspension, performing a full-circle inspection. Their report stated, "Could not find any evidence to support the customer's claim." The service advisor expressed disbelief in the issue I described, stating he had not heard of such problems before. Contrary to the service advisor's disbelief, records on NHTSA.gov reveal numerous instances of sudden unintended acceleration while pushing on brakes for Mazda CX cars (CX5, CX30, CX50). These instances have occurred and have been reported nationally/across numerous states in the USA. I am urging Mazda to thoroughly investigate all reported complaints, issue recalls for affected cars, and enhance their safety features. As of now, there have been no reported fatalities, and it is crucial for Mazda to take proactive measures in investigating and addressing our claims to prevent any potential harm caused by errors in the ActiveSense system.

This is already related to Mazda's recall #23V-275 BRAKE PEDAL TRAVEL CONCERN. My car was already involved in crash which I firmly believe that it was related to the brake pedal issue since the brakes didn't hold off the car and the brake assist system was never activated during the accident. Mazda is claiming that my ABS system serial number is a good part, and their dealership claimed that the problem couldn't be reproduced after they held the car for 11 days! I made several attempts to contact Mazda USA but I am not getting tractions for weeks.
