Mazda CX-90, CX-70 Hit With Four New Recalls in a Week
Despite being just one year old, the all-new Mazda CX-90 has experienced a number of problems so far and currently faces as many as nine separate recalls. Four of them were announced in the past week alone, all affecting the 2024 model.
For starters, software bugs with the powertrain control module (PCM) and battery energy control module (BECM) could cause the engine not to restart after a start-stop event. Some 5,100 units in Canada will require an update to the PCM and BECM software as a result.
The other three new recalls not only involve the CX-90 but also its two-row twin, the 2025 CX-70.
On one hand, a problem with the inverter software could cause the vehicle to enter a fail-safe mode. If this happens, there could be a loss of power to the wheels, Mazda warns. The fix, once again, is a software update, this time on approximately 2,500 units across the country.
The same thing could happen due to various bugs with the PCM and engine control module (ECM). Around 6,200 vehicles need to be brought in for a software update.
Finally, it’s possible that a software problem with the dash electrical supply unit could cause the windshield defroster, seat belt reminder sound and tell-tale, 360-degree view monitor or high-voltage battery cooling system not to work properly. Over 12,600 units are affected and need to have their electrical supply unit reprogrammed.
If we had to bet, we’d say these latest recalls won’t be the last. The good news for CX-90 and CX-70 customers is that they’re all electronic or software-related issues. No mechanical or technical component is directly to blame.
The lone exception was that January 2024 recall involving the steering gear. For some reason, there could be a sudden change in steering feel and an increase in steering effort, so Mazda dealers will replace the spring engaging the worm gear in the steering gear assembly and reapply grease to the gear teeth as a remedy.
