There are 6 owner-reported driver assist & adas complaints for the 2024 Mazda CX-30in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
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.
when driving on the highway in a turn with nobody around with the adaptive cruise set the car it will brake depending on how sharp the turn sometime 5 mph sometimes up to 12 mph like someone just stomped the brake pedal
