Summary
The Mazda CX-90 has 17 recalls affecting the 2024-2025 model years, with the most serious being a suspension fastener issue on 2024 models where missing or improperly tightened steering and suspension bolts can cause the steering shaft, front brake sensor harnesses, or upper control arms to detach, resulting in loss of vehicle control.
The 2024-2025 CX-90 has a cluster of software-related powertrain recalls that all share the same consequence: an unexpected loss of drive power. On plug-in hybrid models, separate software faults in the inverter, the powertrain and engine control modules, and the transmission control software can each cause the engine and electric motor to shut down while driving. A related issue specific to plug-in hybrid 2024 models causes the vehicle to lose drive power while running in electric-only mode. There is also a fault where the engine fails to restart after the automatic engine stop-start system (i-stop) shuts it off, leaving the vehicle without power at a stop. These drive-loss issues span both 2024 and 2025 model years depending on the specific software involved.
Two separate steering recalls affect 2024 models. One involves the worm gear inside the electric power steering system, which can fail and cause a sudden loss of steering assist. A second involves the steering gear itself, which can produce an abrupt change in steering feel and require significantly more effort to turn the wheel.
The 2024 model year also has two automatic emergency braking software recalls that cause the system to falsely detect obstacles and trigger hard, unexpected braking when no hazard is present. Alongside those, a dashboard electrical supply unit software fault can disable the windshield defroster, seatbelt reminder chime, 360-degree camera, and high-voltage battery cooling system simultaneously.
Lower-severity issues on 2024 models include an inaccurate fuel level display that can allow the vehicle to run out of fuel without warning, a reverse warning tone that sounds when the vehicle is not in reverse, and the pedestrian alert system potentially producing misdirected warning sounds due to missing amplifier software.
