Mazda CX-90 Lemon Law

The most serious complaint on the Mazda CX-90 is a loss of drive power. On this new-generation SUV — built around a turbocharged inline-six with a 48-volt mild-hybrid system, plus a plug-in hybrid (PHEV) variant — a software error can cause the powertrain to shut down or drop into a fail-safe that cuts power while driving. Mazda recalled certain 2024 CX-90 PHEV vehicles for a software fault that could shut down the engine and electric motor, and issued a separate inverter-software recall in which a fail-safe could cut power in EV mode. Dealers reflashed the powertrain, engine-control, and inverter software.

Owners also report a range of electronics and software faults typical of a first-year design: the engine failing to restart after the stop-start system engages, surround-view (360°) camera and window-defroster malfunctions tied to the dashboard electrical supply unit, seat-belt-warning glitches, and infotainment quirks. Some owners describe error messages appearing even after a recall software update. Because these are software-driven, they can be hard to reproduce and may take several dealer visits to resolve.

California's Lemon Law applies when a defect substantially impairs the CX-90's use, value, or safety and the manufacturer can't repair it within a reasonable number of attempts, or the vehicle is out of service too many cumulative days. A power loss at speed is a serious safety defect that generally needs fewer failed attempts to qualify, but ordinary generic problems — persistent electronics faults, repeat no-restart events — can qualify too, with or without a recall. A successful claim can mean a buyback, a replacement, or a cash settlement, with Mazda paying your attorney fees.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your CX-90 has been out of service for 30 or more cumulative days.

If your Mazda CX-90 qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and Mazda pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
