Mazda is initiating a recall of CX-90 three-row crossover SUVs due to a software issue that may prevent the engine from restarting when utilizing the engine stop-start system.
This recall pertains solely to the 2024 mild-hybrid versions of the CX-90, which total 38,926 vehicles. The mild-hybrid configurations feature compact battery packs and electric motors that cannot power the vehicle independently, yet they enhance the functionality of the gasoline engine and support an advanced stop-start system.
According to the NHTSA, the affected vehicles might contain “improper” software in their power control and battery energy control modules. This flaw may disrupt the hybrid-assist function, potentially resulting in the gasoline engine stalling. If this happens, a “Hybrid System Malfunction” alert will be displayed on the instrument cluster, accompanied by warning chimes.
Mazda reported receiving seven field complaints about the issue as of October 25, but it is not aware of any crashes or injuries connected to it. The same powertrain used in the affected 2024 CX-90 models is also featured in the 2025 Mazda CX-70, a two-row version of the CX-90, though no CX-70 models are included in this recall.
The solution involves reprogramming both the power control module and the battery energy control module, which dealers will carry out at no cost to customers. Mazda intends to send notification letters to owners by December 30. Additionally, owners can contact Mazda customer service at 1-800-222-5500 and select Option 6, referencing recall number 7024J.
While the CX-90 has achieved an IIHS Top Safety Pick+ designation in its plug-in hybrid variant, it is currently undergoing several ongoing recalls. On the same day the stop-start system recall was announced, Mazda also disclosed recalls addressing a software problem in plug-in hybrid models that could lead to a loss of propulsion, as well as an issue with the instrument-cluster display.
