2010 Mazda MAZDA3 electrical problems

Filed Apr 4, 2026 · Electrical · PA

The AT light came on the dash, added transmission fluid because it was a little low but the light still has not gone off. I think there is an electrical problem within the transmission. It's had shifting issues since purchasing this vehicle. I also have a small child that comes with me to work and I do not want my car to catch on fire while we are in this vehicle.

the federal safety agency Complaint Narrative I am filing this complaint regarding a 2010 Mazda 3, VIN [XXX] . The vehicle experiences intermittent transmission control failures, including difficulty shifting out of first gear and warning indicators triggered by vibration. The transmission and transmission control module have already been replaced. The dealership has identified the wiring harness as the cause of the remaining failure. Mazda North American Operations has confirmed that the required wiring harness (BBM9-67-020H) is discontinued and unavailable. However, Mazda has not provided a written determination of whether the known wiring harness recall (engine wiring harness chafing affecting control systems) applies to this VIN, nor confirmed recall completion history. Mazda has advised the customer to seek aftermarket or salvage parts, but has not provided an approved repair remedy or goodwill assistance despite the issue affecting drivability and safety. I am requesting that the federal safety agency review whether Mazda has met its obligations regarding: 1.recall applicability determination by VIN, and 2.providing an adequate remedy when OEM repair parts are no longer available for a safety-related defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The a.b.s pump module is defective in these vehicles. There are tons of people having issues with them. When they fail it happens suddenly resulting in brake failure, power steering failure, the car does not like to shut off, the vehicle will go into "limp mode" and every light on the dash comes on. The part itself is costing close to $1000 u.s.d . With all of tge effected things tgat go with it i believe it can be very dangerous and should be recalled

The Transmission Control Module (TCM) has gone out on my car, causing it to shift to 2nd gear while doing 75mph with cars around me, and would no longer shift out of 2nd gear, or into reverse. It was an extremely dangerous situation that made me come very close to wrecking into a car, as well as the many cars behind me that had to emergency brake due to my rapid deceleration, especially without and brake lights coming on because it was engine braking. Doing a simple google search show that this is an extremely well-known problem effecting almost every Mazda 3 that used this TCM in 2010-2011. Any mechanic will tell you it's a known problem, and that it was due to where and how Mazda placed the computer, which causes it to overheat and fail without warning. I'm not sure why there has not been a recall on this issue with how prevalent it has been, and how easily recognized it is by mechanics. It is not a cheap fix, and can cause many other major issues leading up to requiring a full new transmission, if the problem did not already cause the car to wreck!

On Multiple occasions the Power Steering goes out and warning light on dash comes on. Very hard to steer without the PS on. This has happened on highways as well as in town in traffic. Sometimes it comes back in a few seconds on its own. Other times the car must be turned off and restarted, if you can get to a safe place. No codes appear when checked.
