Summary
The Mazda CX-30 has 10 recalls covering the 2020 through 2025 model years, with the most serious being a fuel system defect on 2020 all-wheel-drive models where a disconnected evaporative vent hose can allow fuel to leak from the rear of the vehicle, creating a fire risk and potentially causing the engine to stall while driving.
The most recent production years have an airbag concern: on 2024-2025 models, the airbag sensor unit can set an error code triggered by a low battery condition and deactivate the airbags entirely, leaving occupants without that protection in a crash. A related issue on 2024 models involves the battery draining when the ignition is left in the on position for too long; when the battery is recharged and the vehicle restarted, the airbag warning light comes on and the airbags will not deploy in a crash. Moving back to 2022-2023 models, the anti-lock brake system hydraulic control unit can be damaged in a way that reduces braking ability and extends stopping distances. On 2021 models, tire valve stems can be damaged, causing tires to lose air pressure slowly or suddenly while driving, which can lead to loss of control. The 2020 model year carries additional concerns beyond the fuel system recall: front brake caliper mounting bolts may not be properly tightened, and if they loosen further or fall out entirely, braking effectiveness drops and the caliper can contact the wheel rim and cause loss of control. There is also a power liftgate issue that spans 2020-2021 models, where the liftgate can partially drop on its own when the vehicle is parked nose-up on a slope, posing an injury risk to anyone standing near the rear of the vehicle.
