2008 Mazda MAZDA3 Transmission and drivetrain Problems

“At and yellow check engine light came on and car was in limp mode first thing in morning after having no issues with my Mazda previously. Codes came back with solenoids a, b, c, d, e all have electrical failure, and issues with the oxygen sensor. My car has had regular maintenance done on it. No signs or symptoms of transmission failure beforehand. Happened instantly overnight. Tcm is not in stock anywhere and I suspect that is the culprit due to other Mazda owners similar situations. 95k miles.”

“I was driving when suddenly and without notice I lost all control over the engine. Pressing the accelerator down did not change the engine speed. The engine would only idle. The car was towed to the dealer who determined that a bad connection occurred between the wiring and the ?PCM? Module. If this had occurred while passing or while executing a left turn, a serious or even fatal accident could have occurred. Ma 10/22/2015”

“I parked my car on numerous occasions in the last few months where the transmission failed to engage in park. It required multiple tries to get the park indicator light on the dash to reflect that the car was safely engaged in park. Before I realized what was happening with the transmission.

The problem with failing to start happened when the car was on a slight incline and I had engaged the parking brake. …”

“I was driving at normal speed when with no warning, the car jerks suddenly. I was extremely startled as it felt like I had broken an axle or ran over something big in the road. For unaware drivers it can cause an accident if they swerve in reaction. It happened about 5 more times in a 1 hr drive and just kept on happening whenever I drove it for the next 2 days at higher speeds or lower speeds, I then noticed that my display showed the gear to drop from 5th suddenly into 3rd or 4th to 3rd. …”

“Car was vibrating a lot when in gear and holding brakes replaced motor mounts and throttle body to fix issue. Also when slowing down and speeding back up the transmission grinds when down shifting. Feels like it is slipping and is not safe if you are driving on the highway or in the city and want to switch lanes and speed up I'm afraid one day I'm going to switch lanes hit the gas and the transmission will fail. The carmax I got the car from insists it is just a transmission shutter and it happens with certain cars. I will be getting a second opinion from an ase certified transmission shop. …”
