2024 Mazda CX-30

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. The Recall also states: "Due to an improper program setting, affected FSC (cameras) were not updated from production mode to normal mode. As a result, all three systems described (HBC, SBS, LAS) will not work as intended." My cameras are definitely not working as they should. I have had it in for service, and the technicians have not done anything at all. The Recall should definitely be expanded to owners experiencing these issues. As I have stated above, this incident has occurred at least 7-8 times, so I'll just enter in the most recent time that it happened in the Additional Details below since I cannot enter all of them. Thank you.

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. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? It first happened soon after I bought my car new.

Cruise control and lane keeping system engaged. Vehicle will occasionally aggressively apply brakes, when nothing visible is in front of the vehicle. This has nearly cause our car to be rear ended on a number of occasions. I suspect the system mistakenly interprets a building or vehicle shadow as a physical object. This response has also occurred when vehicle in front (cruise control distance at slower speed) turns right. Again, nearly causing vehicle behind to be rear ended.

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.

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 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.

The contact owns a 2024 Mazda CX-30. The contact stated while attempting to accelerate from a stop light, the braking system erroneously activated causing the vehicle to abruptly stop. 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 contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 2,500.

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.
