Mazda North American Operations is recalling certain 2024-2025 Mazda3 and CX30 vehicles. The Sophisticated Air Bag Sensor (SAS) units may set an error code and deactivate the air bags, due to a low battery condition.
Mazda North American Operations (Mazda) is recalling certain 2024 Mazda 3, CX-30, and 2025 CX-50 vehicles. A malfunction in the forward sensing camera (FSC) may prevent the automatic emergency braking system and the lane-keep assist system from functioning. In addition, the headlights will not automatically adjust from high beams to low beams as intended.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Since purchasing the vehicle, the braking system has activated on its own for no reason. Today, Oct 19, 2026, it was cold and it said the system was failing. My camera system fails when it rains. My 2024 Mazda CX-30 has 62,000 miles and is experiencing the exact catastrophic phantom braking and forward camera failures detailed in NHTSA Recall 24V649000 (Mazda Campaign 6824H). My VIN is currently excluded from the recall campaign, but the vehicle is a severe highway safety hazard due to spontaneous unprovoked braking”
“Reporting Product Defect in Mazda Vehicles I am writing to bring to your attention a recurring design flaw affecting current Mazda vehicles, including models such as CX30, MX30, and potentially the Mazda3 series. Following heavy rain or high humidity conditions, there is a consistent issue with the tire pressure sensor alarming and the smart key being unable to unlock the car doors. I have checked my key fob battery, RF function, car battery - none of these are the root cause. Despite consulting local dealerships and various Mazda forums, no one seems to have a definitive solution to this problem. Therefore, I am reaching out to report the existence of this product defect. This issue appears to be more prevalent during summer in Arizona - after the thunderstorms, this issue came up every time. Even with the heat here, it takes from several hours to 2 days for the affected part to dry out and function again.”
“The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. Due to the failure, the contact crashed into the vehicle in front of her as the "Vehicle System Malfunction, Have the Vehicle Inspected" warning message appeared on the instrument panel. The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it remained in their possession. Neither the dealer nor the manufacturer had yet been notified of the failure. The vehicle was not repaired. The failure mileage was 38.377.”
