What's wrong?
The powertrain control module and engine control module on the 2024-2025 Mazda CX-90 and CX-70 are computers that manage engine output and drivetrain behavior. The PCM helps coordinate power delivery through the powertrain, while the ECM controls engine operation. Together, their software decides how much torque the vehicle should deliver as driving conditions change.
In affected vehicles, the software can miscalculate under specific driving conditions. When that happens, the vehicle detects a fault, turns on malfunction indicator lights, and enters a fail-safe mode. Fail-safe mode is meant to protect the engine and driveline, but in this recall it limits drive power. That leaves the driver with reduced acceleration or loss of motive power.
The warning sign is an illuminated malfunction indicator lamp on the dash. If that light appears with reduced power, tell the Mazda dealer the concern involves recall 24V815 and the PCM and ECM software.

What's the safety risk?

What should I do?
- Check your VIN to confirm your 2024 Mazda CX-90 or 2025 Mazda CX-70 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free PCM and ECM software update that addresses warning lights and loss of drive power.
- Bring the recall notice if Mazda mailed one. If not, reference recall number 24V815 when you call.
- Drive cautiously until the repair is complete, and stop in a safe place if warning lights appear or drive power drops.
What happens at the repair
At the dealer, a Mazda technician reprograms the PCM and ECM software that controls powertrain and engine operation. The software update is free under the recall, with parts and labor covered. Mazda is not offering a separate reimbursement program because all affected vehicles are under full warranty coverage. Out of pocket repairs already paid are handled through the existing warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
