2026 Mazda CX-90

On multiple occasions, the steering wheel became stiff or locked while driving or during start-up, multiple dashboard warning lights illuminated, and the vehicle could not be shifted from Park to Drive. This occurred repeatedly since the vehicle was purchased. The dealer inspected the vehicle multiple times; on the first attempts they could not duplicate the issue. On a later visit, the vehicle displayed a lost communication fault with the electric power steering (EPS) system, and the dealer replaced the steering gear/rack assembly and EPS motor per the manufacturer’s technical hotline instructions. Despite this part replacement, the same steering/warning light condition recurred weeks later. At that point the dealer confirmed the defect but stated there is currently no authorized repair or parts replacement available, and that engineering is developing a permanent corrective action. The vehicle remains in my possession and is available for inspection. This defect creates a serious safety risk because the vehicle cannot be steered or shifted normally when the condition occurs, including while driving. No crash or injury has occurred to date.”
