Mazda built its reputation on reliability. For decades, the Japanese automaker earned trust with vehicles that simply worked. That’s what makes the CX-70 and CX-90 situation so surprising and concerning for current owners and potential buyers.
The Promise vs. The Reality
When Mazda launched these flagship SUVs, they represented the brand’s boldest move upmarket. The CX-90 offered three-row seating while the CX-70 targeted buyers wanting a sportier two-row alternative. Both came with premium pricing to match their premium ambitions. Mazda offered these models in traditional gasoline powertrains and cutting-edge plug-in hybrid versions, betting that technology would attract luxury buyers.
Consumer Reports’ latest reliability survey tells a different story. Both models rank among the least reliable vehicles on the market, with problems persisting into their second model year. This isn’t just new-model growing pains anymore.
What’s Actually Breaking
The plug-in hybrid versions face the most serious issues. Owners report problems with the electric battery systems and motors, the very components that justify the PHEV’s premium price and environmental benefits. When these systems fail, owners lose the electric driving capability they paid thousands extra to obtain.
The gasoline versions aren’t trouble-free either. Reports indicate various mechanical and electrical problems that undermine the ownership experience. For vehicles costing between $40,000 and $55,000, these reliability scores represent a significant value problem.
What This Means for Owners and Shoppers
Current owners should stay vigilant about warranty coverage and document any issues immediately. Mazda’s warranty will cover most problems, but keeping detailed records helps if patterns emerge.
For shoppers considering these models, the data suggests caution. First and second-year models of redesigned vehicles typically experience the most problems, and these Mazdas fit that pattern perfectly. Waiting for Mazda to address these issues in later model years makes sense or consider Mazda’s more established models with proven reliability records.
The CX-5 and CX-50 maintain much better reliability ratings and offer most of what buyers want from Mazda. Sometimes the newest and flashiest option isn’t the smartest choice, especially when your daily transportation depends on it.
