Hybrid battery recall was replaced and failed a month later for a second time burning other systems and causing a compete failure in the car. It failed in a deserted portion of [XXX] while traveling from [XXX] to [XXX] for important business. This left me stranded in the middle of the [XXX] desert late at night in a dangerous area. It failed on the highway loosing complete power with multiple failures reported on dashboard. I was left stranded in the middle of nowhere with no nearby services or immediate assistance and was forced to remain in the vehicle overnight in unsafe conditions. The vehicle required towing, and I was later informed the issue was again the hybrid battery the same component that had already been replaced under recall less than one month prior. This repeated failure creates a serious safety concern because the vehicle can unexpectedly lose power and leave occupants stranded without warning, even in remote or unsafe locations. In addition it lost power on the highway and that posses a significant safety concern. The vehicle is unreliable given its age and repeated failures, and I am requesting investigation into a potential safety defect involving the hybrid battery system and sudden loss of propulsion/power and damages to other parts. I had 8 different warnings on my dashboard before the car completely died and I couldn’t even open or close windows or lock and unlock doors.

There is an intermittent issue where the dashboard will indicate that the rear side radar is obscured and turn off all the safety features of the car. This happens typically on a clear day when there should be no issues. Turning off the car resets this. Its unsettling because as there are quite a few blind spots in this vehicle you are dependent on the blind spot warning, especially in heavy traffic. Reported it to dealer but they indicated since its intermittent there isn't much they can do. Ridiculous for a new $45k vehicle

On March 14, 2026, I was attempting to turn left into a parking stall within a busy shopping center lot when my vehicle suddenly accelerated unexpectedly. I lost all control of both the steering and the braking systems. This resulted in my vehicle striking a parked car to my left, jumping a cemented planter border, and coming to rest in the adjacent parking stall. Fortunately, the other vehicle was unoccupied, and both my passenger and I were uninjured. Local law enforcement was contacted; however, they indicated the policy officers will not be sent to the seen to file a report as there were no injuries. They did assist in identifying the owner of the other vehicle. I have initiated a claim with my insurance carrier, American National Property and Casualty Co (Claim #10401408), and have opened a case with Mazda Corporate (Case #00428640). Mazda has indicated that they require a report from my insurance provider to proceed with a technical investigation. Please advise what other steps I need to take.

I was stopped by a railroad crossing and when I started driving, my automatic emergency braking activated and jerked to a stop. This happened two consecutive days in a row. Gratefully no one was behind me, or they would have rear ended my vehicle.

The car automatically brakes at lower speeds. This happens about 3x week and typically on a specific freeway entrances but in other locations as well. I believe this is a known phantom braking issue but for some reason my car is not included in the recall.

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 Mhev verdict →
