Has I was driving my car home from work. Driving about 35mph I started to loose power and then the at, engine, tcs/dsc lights all came on. When I made it home I let it sit. While I looked into the issue on google later that evening I went back to see if my car was still having the issue. I placed the car in reverse and my car jumped/ jerked real hard. As I let go of the break I noticed my car didn't slowly move on its own like prior. I actually had to press the gas down quite a bit. My car revved up to 3 making a loud noise. The car had no power would hardly move. As I researched the problems and light issues it was kinda a surprise how easy it was to figure out what the issue was. Since this is a very very common issue found with the mazda cars. So many people have this issue that when you order the part at over $600.00 in the directions that is sent they actually recommend relocating the TCM to a different location using zipties. Went to have car codes read on my car informed the guy what I believed it to be and the most likely will be u0101 lost communication with TCM, and I was correct.

There is a recall applicable to my vehicle which requires that engine mounts be stablilzed. It makes my car vibrate and the engine sounds loud while seated in the vehicle. I have taken my car to a couple of dealers and they say they don't have the required part. I was scared to drive my car.because it was smoking from under the hood. I let it sit in my garage since 2008. I finally took it to a mechanic who told me that the engine had caused a hole in the coolant tank and it was leaking coolant. That's why it overheated. The car runs fine now, but needs to have the engine mount put in. What do I do now? In addition, my driver side window will not operate. I thought this was a fuse issue, but another mazda 3 owner told me they have the same issue

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.

The mazda dealer did not have the equipment to make the harness fix. I continued to drive my car and one day, my car had loud roaring sound. Within a couple days later, it began to emit white smoke from under hood and black smoke from tailpipe and begin to lose power on freeway off-ramp. I coasted to bottom of off ramp. Then I was able to restart it to move it to a nearby kaiser lot adjacent to exit ramp. From there, I had it towed home and have not driven it since.
