On or about [XXX], I leased a 2025 Mazda CX-90 PHEV Premium Sport from Bob Penkhus Mazda, Colorado Springs, CO. Within approximately six weeks, on [XXX], while traveling south on [XXX] from Pueblo toward Walsenburg, the vehicle experienced severe loss of power under load. Despite the accelerator being fully depressed, the vehicle would not exceed 74 mph on the initial incline and later would not accelerate past 64 mph near La Veta Pass, even in sport mode. During an attempt to pass a slow-moving truck, the vehicle failed to accelerate, forcing me to brake hard to avoid a head-on collision. My fiancée and our infant twins were in the vehicle at the time. I immediately contacted Service Manager Steven Constable at Bob Penkhus Mazda. The dealership retained the vehicle for inspection but claimed they “could not duplicate” the issue because “they don’t have mountains to drive it up.” No repairs were made. Instead, I was told to “drive it for 30 days to monitor,” despite the documented safety risk. I refused to assume that risk and requested a repurchase, replacement, or trade into a non-PHEV model. I even offered to accept a lower-trim base model, provided it had captain’s chairs, and to continue paying my current monthly amount. The dealership and General Manager A.J. Ager rejected this and demanded that I personally pick up the unrepaired vehicle, although they knew I live three hours away in Monte Vista and Mazda advertises complimentary pickup service.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Mazda Cx-90 Phev verdict →
