2010 Mazda MAZDA3: check engine light

Filed Jul 1, 2024 · Transmission · OH

Transmission control module issues. Car was driving on the expressway and wouldn’t shift out of second gear. Engine light and AT light came on. Had to drive slowly on the expressway and get off on the closest exit. Cars were speeding past me and I had to be careful not to get hit. Research and shop shows the 2010 Mazda 3 vehicles have lots of issue with the TCM because they get hot due to there location.

The check engine light came on and the car began stalling as I drove on the freeway. It stalls and feels like it won't change gears. Took it to a shop and they kept telling me the computer code was not giving them any information and they couldn't figure out what was wrong with it.

Within a week after purchasing my 2010 mazda 3 s sport sedan in october, 2018 from a used car dealer in midvale, ut, the check engine light came on. Using a code reader, I consistently get a code of p0421, which indicates that the catalyst efficiency is below threshold. I have had 3 auto repair shops look at my car, and they all say that the catalytic converter is not operating properly and needs to be replaced. Despite the fact that mazda warrants california emissions/pzev vehicles (which mine is) for a period of 15 years or 150,000 miles on all emissions related components, they will not repair my car under warranty because I currently do not live in a state that uses ca emissions standards when testing vehicle emissions. I feel that since my car is not performing as it was designed and may be releasing my pollutants into the atmosphere that it should be repaired by the manufacturer at no charge to me, regardless of where I currently live. In addition, when I start the car on a cold engine, I can smell exhaust fumes inside the cabin, which leads me to believe that there may be a leak at the exhaust manifold gasket which could be dangerous to anyone driving the car if they inhale the exhaust gases that may enter the passenger area through the ventilation system. The check engine light continues to go on daily (unless I reset it, and then it goes back on again later after driving) and my car will not pass its next emissions inspection without this issue being fixed.

Mazda 3 engine light on for 2 years. I have taken car to multiple mechanics and in 1-2 days light is back on. Recently car seems to hic cup on shifting and on braking the back end of car seems to run into the front end. In last 2 wks an at light came on and car almost wouldn't shift in gear. I have a verizon hom and got s message indicating 'solenoid stuck on e'. When I called firestone they stated those mazda 3 have that problem and that I need to take car to mazda. In trying to understand my issue I googled problem that showed there was a electrical recall that may cause engine to stop or problems shifting.
