Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After a long drive, 250miles, stop to put fuel in the vehicle, I removed the fuel cap and gas blew out of the filler all over me, car, ground. Seems the fuel tank was under some kind of pressure. The pressure continued and I was not able to put fuel in the vehicle. If something would have ignited I would have been set on fire. Was not able to refuel the vehicle until the next day. This is a loaner car from the Mazda dealership. I experienced a problem like this with my 2024 CX-90 once but it would not allow me to put fuel in the vehicle. …”
NHTSA complaint #11774100, filed 2026-10“Involuntary acceleration. Twice now at very low speeds between 1-5 mph the engine revs up and the car lurches forward for a second or two. Was pulling into house garage and was about to push acceleration pedal when the engine revved on its own and jolted the car forward. I slammed on the brakes real quickly when it happened and slid to a stop almost a foot away from crashing into house wall. I don't know for sure but I feel if I hadn't pushed the brakes it would have continued. Has happened one other time to a different driver, same car. …”
NHTSA complaint #11631266, filed 2024-12“CX-70 routinely has been falsely alerting to an impending crash when no vehicles in front or to the sides. Vehicle routinely does not alert when there is traffic to left or right when merging into a lane. Multiple near accidents when a vehicle was present in blind spot when merging lanes and the safety system failed to steer away or make an alert noise. Vehicle routinely alerts to take over steering wheel even when both hands are on steering wheel. …”
NHTSA complaint #11682916, filed 2025-08“After fuel gage recall completed, vehicle still doesn’t read fuel level correctly. Sometimes doesn’t show fuel level at all, sometimes, after refueling to a full tank, computer only shows 250 miles of range.”
