Engine Stall After i-Stop and Loss of Drive Power
The engine fails to restart after the i-stop idle stop feature turns it off, leaving the vehicle stranded in traffic. Additionally, the PCM and ECM software may cause malfunction indicator lights and a complete loss of drive power while driving.
Mazda issued multiple recalls addressing the i-stop restart failure and loss of drive power with free PCM/ECM software updates at the dealer. Multiple software updates may be required as Mazda has issued iterative fixes.
Est. Cost: $0 (recall)Automatic Emergency Braking False Activation
The AEB system falsely detects objects while driving and applies the brakes suddenly without cause, creating a crash risk for following vehicles. This accounts for 27% of all NHTSA complaints for the 2024 CX-90.
Mazda issued a recall for the AEB system with a software update to improve object detection accuracy and reduce false activations. Dealers perform the update free of charge.
Est. Cost: $0 (recall)Cylinder Head Coolant Leak at Exhaust Manifold
Coolant leaks develop at the cylinder head around the exhaust manifold area, with cracks forming at the stud bolt hole or at the outside of the exhaust manifold flange. This affects the inline-6 turbo engine and can lead to overheating if undetected.
A Mazda TSB addresses the coolant leak with cylinder head inspection and repair. In severe cases, cylinder head replacement is required. Dealers should check coolant levels and inspect for external leaks at every service visit.
Est. Cost: $0 (warranty) / $2,000 - $5,000 if out of warrantySteering Power Assist Sudden Loss
An assembly issue with the worm gear in the electric power steering system may result in a sudden and complete loss of power steering assist while driving. The steering wheel becomes extremely heavy to turn, making the vehicle difficult to control.
Mazda issued a recall to inspect and replace the steering gearbox assembly on affected vehicles free of charge. Dealers will check for proper worm gear assembly and replace the unit if any defect is found.
Est. Cost: $0 (recall)MHEV Battery Cell Imbalance and Fuel Gauge Inaccuracy
The mild-hybrid (MHEV) 48V battery develops cell imbalance (DTC P0DAB), causing the mild-hybrid system to malfunction. Additionally, the fuel gauge in the instrument cluster may display inaccurate readings, risking unexpected fuel starvation and stalling.
Mazda issued a recall for the inaccurate fuel gauge with a software update. The MHEV battery issue is addressed per TSB with battery replacement when cell imbalance is confirmed. Mazda has experienced significant backorder delays on MHEV batteries.
Est. Cost: $0 (recall/warranty) / $1,000 - $3,000 for MHEV battery if out of warranty
