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.

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 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.

I believe that (recall campaign 0917B) safety recall applies to my 2010 Mazda3 GT, although it took over 2.5 years to occur (August 2017) the complete fallouts didn't happen until now...(December 2020) initially, felt a pop in my back (from the frame?) while I was driving, pulled over and the seats moved fine so didn't think anything of. Meanwhile, a distinct rattling occurred intermittently behind me. Took the car to the local dealership (paid their special service diagnostic fee of ($165+) with 'master technicians' who know about this seat recall, yet, found nothing wrong with the seat or even looked if you ask me, yet wanted me to correct the noise by by installing both front and rear new suspension (~$1000). Took the vehicle to a suspension specialist and found only one (1) part of the suspension that may have required correcting but was still in good condition. I asked if the remaining suspension components were safe and if they would need replacement. And they said'no' only one (1), and it was barely damaged, but I replaced it anyway. Took it back for an oil change since they were treating me honestly. Two days later, as I was leaving my work, the seat fell off the right rail as I was driving. In retrospect, the push nuts on the right side popped off and the driver's seat back frame has lost its integrity, so I sat askew. Unable to drive safely unless a piece of wood is holding the seat to the rail. Is it possible to still repair my car's driver's seat under the aforementioned safety recall? I don't feel safe driving and am without options at this time. Please help!!

I am having a starter problem. I have replaced the battery and have had diagnostics done on alternator and starter. Both passed except there was a recall on 2010 Mazda's that isn't showing under my VIN number. Recall number 09V126000. I've taken it to get looked at and have an appointment with Mazda. I just don't want to be rejected for this recall.

At approximately 49,000 miles the left front passenger door lock actuator and latch started to fail. This causes the locks to lock and unlock repeatedly at all speeds. This happens randomly and is sometimes made worse depending on temperature or how bumpy the road is. I have narrowed it down to the connector on the actuator being loose and not always making a good connection. The issue causes all doors to lock and unlock or just stay unlocked while driving. I also have to keep the dome lights turned off because sometimes they would stay on. The computer was thinking that the door was open. I'm setting the date of it happening at the beginning of the month but it has been going on for some time now.

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.

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

Engine stalls due to vibration while driving. There was a recall for this exact problem, but Mazda isnt honoring without me paying for repais first. As I was turning in front of an 18 wheeler dash lights came on and I temporarily lost power. Shut off and back on again

I've scheduled the recall repairs three times, with three different Mazda dealerships, since June 2018, when my hatchback smashed against my head (pictures attached). Each time a day or two before the scheduled recall repairs each dealership had called and canceled the recall repairs with no availability on a reschedule date available. This is completely unacceptable. I attempted to reschedule the recall repairs today August 21,2019, there is no dates available at any Mazda dealerships within 100 miles of my location for more than one year from now. So in my opinion this is Mazda completely failing to complete a timely repair on Mazda recalls.

While driving the vehicle dash lights start blinking and car stops accelerating, turns on by won't move. Mechanic says engine is not communicating with transmission. Electrical issue seems like. When it rests it will work but then after driving it happens again. It just stops while you are driving, dangerous.

Push button start malfunction, causing instrument panel to light up and behave erratically. Car obviously not safe to drive at that point. Shifting into reverse louder than normal and very noticeable jerk. Same result when shifting back to drive. Did not attempt any movement. Shut off engine. Waited several seconds, attempted restart, but engine would not restart. Instrument panel was lit up with a red key indicator light. Towed to dealer. Could not diagnose failure. Reset system, ran full diagnostic, no failure codes reported. Drove fine for 2 days, on 3rd day, problem repeated itself, car is now back at the dealer waiting on repair/diagnosis. Car was parked in home garage southern AZ on both occasions.

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.
