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.

Aug 25, 2025Fuel systemLane DepartureDriver assistance

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. I do not feel confident in the safety systems as they are not executing safety procedures as described in the vehicle manual and appear to be defective. Vehicle fuel gauge consistently under reports the amount of remaining fuel. This causes the gauge cluster to fall to empty faster than it actually should be.

My auto flashed an Engine Malfunction error then lost power. I had to pull over immediately. Would not restart. Unsafe road with no shoulder in a no passing two lane road. Towed to dealer. They told me gas tank sensors failed. Resolution is a new gas tank. This could have been much worse had there been a car behind me, had children in car, been on a highway etc. The auto did not show any signs of issue until the warning light that appeared as the auto lost power. The auto is at the dealership where it will remain until new part comes in. I was told there has been an influx of this part being requested and it could be 2 months before one is available. Very dangerous. Mazda road side assistance sent tow truck.all communication with dealer has been via phone except for text letting me know the auto arrived there.

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. Aside from possibly sending me crashing through my house I live next to a school and children and families are walking across the crosswalks all the time. If it were to happen when someone was in front of me I'm scared of what would happen, or even just parking at the grocery store I could easily slam into the car in the next spot. There were no warning /safety lights or any error lights on the dashboard before or when this happened. Not sure what caused it so I checked multiple boxes of what I think it could possibly be. Mazda has a recall out but I checked my vin and so far it's not registering a recall. My technician at the dealership is off today but I will call back tomorrow and talk to him about the incident.

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-70 Mhev verdict →
