This Problem Across All Years
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 problem has not been inspected by Mazda yet, but a formal safety review is requested. The issue posed serious safety risks due to total loss of braking control and unexpected air-bag deployment.

When driving the vehicle incorrectly thinks there is an object in front of me and engages the emergency braking function. This has happened 3 times since getting the vehicle. The vehicle also occasionally incorrectly indicates there is a vehicle next to me when I turn on my turn signal. This has happened on a clear, sunny day. The incorrect emergency breaking could put me at a collision risk if another car is behind me and/or if engaged when driving at a high speed. This could endanger my life. I took my vehicle in to the dealership to explain the issue and they “could not replicate the issue” thus it was not fixed. There were no other warning signs indicating something is wrong with the vehicle.
None of the features dependent on the Forward Sensing Camera (FSC) of my 2024 Mazda CX-30 are working. I have videos and corroborating statements to confirm that the headlights will not automatically switch from high to low beams, the lane assistance is not working properly, and the "Smart brake support with pedestrian detection" is not working. These defects have been present since I first received the vehicle. The dealer has refused to repair the issues by applying the remedies available under recall number 6824H because my VIN is not included in the recall. I emailed Mazda asking them to contact me and to call the dealer and authorize them to replace the Forward Sensing Camera. I am still awaiting reply from Mazda.

When the cruise control is canceled and the speed has dropped more than a couple of MPH when it re-engages the accelerator goes full throttle just like you've mashed the pedal to the floor. Also when in an HOV lane with a dividing wall to the left and going around a highway curve it modulates brake/gas/brake/gas, etc. It will also occasionally pick up another vehicle on either side when on a highway curve and do the same thing. But it seems to operate properly in a straight line. I have spoken with Mazda Customer Service several times. The 1st case which was opened they never contacted me and closed the case. The 2nd time they have contacted me on several occasions but I don't seem to be getting their attention.
