What's wrong?
The inverter on 2024-2025 Mazda CX-70 and CX-90 plug-in hybrid SUVs is part of the electric propulsion system. It manages power between the high-voltage battery and the electric motor, so the motor receives the electrical output it needs when the vehicle is driving in electric vehicle mode.
Mazda says the defect is improper inverter software. In affected SUVs, that software is capable of activating a fail-safe mode that limits motor power while the vehicle is in EV mode. When that happens, the SUV loses drive power from the electric motor, even though the issue is software-related rather than a broken mechanical part.
The warning signs are tied to the vehicle's alert system. Mazda says the malfunction indicator light illuminates, and the warning chime is also part of the alert before or during the loss of drive power.
Who's affected?
The CX-70 and CX-90 scopes share the same inverter part, tied to the electric propulsion system and electrical system software.

What's the safety risk?
A loss of drive power increases the risk of a crash, especially in traffic. If the Malfunction Indicator Light comes on or the warning chime sounds, drive cautiously, move out of traffic when safe, and schedule service soon. Repair is free at any franchised Mazda dealer.

What happens at the repair
At the dealer, a Mazda technician installs improved inverter software for the plug-in hybrid inverter system. The recall repair is free, and parts and labor are covered. Mazda is not offering a separate reimbursement program because all affected vehicles are under full warranty coverage.
