2024 Mazda CX-30 Problems & Owner Complaints

Forward Collision Avoidance 8 1 crash 2 injury

“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…”

“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 compo…”

“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.”

“Component/System: Automatic transmission (requires full replacement). The vehicle is currently located at Safford Mazda of Fredericksburg, 10653 Patriot Hwy, Fredericksburg, VA, 22408, and is available for inspection upon request.

“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 pat…”

“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”…”

“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 co…”

Seats 2 1 fire

“I have a brand new Mazda CX-30 with less than 10k miles. I was not made aware of the seat material being highly flamible. Luckily I nor my kids were in the car when the seat caught fire due to a magnifying effect. Magnifying Effect (Sunlight): If a clear glass or plastic object (like a water bottle, eyeglasses, or even a certain type of air freshener) was left on the seat in direct sunlight, it could have acted as a lens, focusing the sun's rays onto a small area of the seat material. Over time, this concentrated heat could become intense enough to ignite the fabric, especially if it's dry a…”

Power Train 1

“I had both the left front and right front CV axles fail. My car only has 11.5k miles on. I first heard the clunking noise at 11k miles, went right to the dealer and had them watch me recreate the noise and they determined the axles needed to be replaced. This is incredible dangerous as the CV axle could have been completely disconnected from the wheel assembly leaving my car useless and uncontrollable.”
