Mazda CX-90 and CX-70 recalled for power loss, electrical issues

• Mazda issued two more recalls for the CX-90, and the CX-70 joins recall list
• One issue stems from an inverter software issue while the other has do to with faulty software in the dashboard
• New software is the fix for both issues

Mazda is recalling CX-90 and CX-70 crossover SUVs for two separate software-related issues. One could cause loss of power in plug-in hybrids while driving in electric mode, the other could interfere with dashboard displays.

The first recall covers 14,902 vehicles, including 2024 Mazda CX-90 three-row crossovers and 2025 Mazda CX-70 two-row models, both with the available plug-in hybrid powertrain. A software issue in the inverters of these vehicles could activate a fail safe that cuts power when driving in all-electric mode, according to the NHTSA. If this occurs, a dashboard warning light will illuminate, possibly accompanied by a warning chime.

The second recall addresses potentially faulty software in the dashboard electrical supply units of 80,915 vehicles, including 2025 CX-70 crossovers and CX-90s from both the 2024 and 2025 model years. Software issues could prevent window defrosters, seatbelt warning systems, 360-degree camera systems, and the cooling of plug-in hybrid battery packs from functioning properly, according to the NHTSA.

The remedy for both recalls is new software, which dealers will install free of charge. Mazda plans to mail owner notification letters for both recalls December 30. Owners can also contact Mazda customer service at 1-800-222-5500 and select Option 6 for more information. Mazda’s reference number for the inverter software recall is 7024J, while the number for the dashboard electrical supply unit software recall is 7124J.

Mazda introduced the CX-90 for the 2024 model year, adding the CX-70 for 2025. Both are offered with a choice of plug-in hybrid and mild-hybrid powertrains, and owners of CX-90s with the latter powertrain have an additional recall to keep track of.

Mazda also recently announced a recall of 38,926 2024 CX-90 models for a problem with engine stop-start systems that could prevent engines from restarting. This is also software-related, with improper software potentially interfering with the hybrid assist function, causing the gasoline engine to stall. A software fix has also been devised for this issue, and it should be available within the same timeframe as the fixes for other two recalls.
