Steering is by far the dominant complaint theme for the 2024 Mazda CX-90, accounting for a large share of the reports filed. Owners frequently describe intermittent or recurring power steering failures, the most common pattern is the steering warning light illuminating while driving, sometimes accompanied by a noticeable increase in resistance or a momentary stiffening during turns, particularly at larger steering angles. Some owners report the issue cycling on and off, while others describe the steering feeling locked up briefly during left turns. The forward collision avoidance system draws the next-highest complaint volume, with owners reporting unexpected activation or system warnings during normal driving. Engine complaints, a smaller but notable cluster, center on sudden stalls and loss of power while in motion, sometimes accompanied by a malfunction warning on the dash.

The 2024 Mazda CX-90 has 20 recalls, the most serious being missing or loose steering and suspension bolts that can cause steering components, brake sensor wiring, or control arms to detach, resulting in loss of vehicle control.
Several software-related recalls affect drive power. The powertrain and engine control software can push the vehicle into a fail-safe mode and cut power to the wheels without warning. On plug-in hybrid models specifically, the engine and electric motor can shut down unexpectedly while driving, and the engine may also fail to restart after the automatic stop-start system shuts it off at a stoplight. A separate software fault can cause the automatic emergency braking system to trigger a sudden hard stop when no obstacle is present.
On the steering side, a worm gear assembly issue can cause an abrupt loss of power steering assist, making the wheel noticeably harder to turn.
Several visibility and electrical recalls cluster around a dashboard electrical supply unit that can fail at startup, leaving the windshield defroster, 360-degree camera, and seat belt warning inoperative. The front, rear, and side camera images can also fail to appear on the display entirely. On mild hybrid models, the fuel gauge may show an inaccurate reading, raising the risk of the vehicle running out of fuel and stalling unexpectedly.
The lowest-severity recall involves the pedestrian alert sound system, which may produce inaccurate tones that can mislead pedestrians about the direction of an approaching vehicle. There is also a Canadian-market filing for a reverse warning sound that plays when the vehicle is not in
