Strange loss of ignition while driving, just for a split second, then ignition returns. Happens mostly during slight right turns, when right turn signal running. Very hard to reproduce, but happens more frequently at night when lights and other electrical on. Mechanic thinks it's in the steering column where ignition wiring and modules are. Haven't fixed it. Just trying to analyze exact cause. Must reproduce at-will to fix. Have to take out steering wheel. Too much hassle at the moment. Will diagnose over time. Car runs pretty much great except for those sporadic loss of ignition like the car goes off the "on" position. Not related to the ignition slot or key. Can pull and push on it with no effect. Not weight pulling key downwards either. Mostly when steering wheel is slightly to the right and right signal running. Very strange.

Very intermittent problem. While driving, getting very short periods of hesitation, total ignition failure and lighting off but ONLY for a split second, then it returns to ignition and all electrical running and keeps going with no issues. Seems like a bad ground issue that only occurs under certain conditions and movement. Gets worse in rain/wet conditions. Very difficult to troubleshoot. Seems like an issue in the steering column/ignition circuit, and generally happens more when the headlights are on. Very short period of single loss of total power, for milliseconds, hesitates and then comes back on like nothing ever happened. I just hope it's not in the ECU or a connector to the ECU. This will take time to troubleshooting. Will post updates. Doesn't happen very often, maybe once a week. Will first have to tighten down all ground wires and go from there. 
Jun 2018

The turn signal function is INSIDE the ECU for this car. I believe that the problem is due to a bad ground somewhere as the only time I lose occasional ignition is when the turn signal is flashing and other loads happening (or so it seems). I added more grounding wire to hopefully eradicate the issue as I believe it's due to an intermittent bad ground state. Also reconnected the ECU to see if dirt / capacitance build up may be an issue. The turn signal flasher (controlled by ECU main computer) is what causes the ignition grounding most times. I am still guessing, but hopeful it's "just a bad ground" and not the ECU itself. Intermittent and the ignition comes back on quickly in just ONE time at the beginning of the first flash... After that it doesn't do the ignition shut-off more than once and the car recovers quickly, even at-speed. Very little momentum loss just a "flicker" like a reset.

Every 20K miles the Mazda chews thru tires. Tires that are warranted to 60K. Finally after 3 alignments in 5 years, a mechanic tells me the front suspension probably came out of spec from the factory and cannot be fixed. Passenger side seatbelt connector rattles every time the temp drops below 40 degrees F. Connecting belt to it or stuffing things down between seat and connector doesn't help. DRIVES ME NUTS! When passenger side window reaches top there is a loud "snap". Other owners report similar issue. No repair. It happens randomly so not too worried about the issue. 3/29/11 Dealerships says clicking from front wheels under torque and clicking front passenger side seatbelt connector are "operating as designed." reported bass drop at 34/35 on radio. Original dealer delivered car when new even though this radio/changer was on recall. Just a quirk now. Not interested in repairing. Also, light on cig lighter fails at times. part not in stock. Rear end started making a rattle/jangle noise when hitting low speed ruts. Body on driver's side has dropped. Haven't yet found the issue. car is only 5 yrs old and 53+K on the odometer.

The car's CEL and AT lights were on. The transmission would not shift out of 3rd gear and started hesitating. The OBDII code P0753 showed it was a problem with the Shift Solenoid A. The shop drained & flushed the trans fluid, replaced the filter and Shift Solenoid A. After a few miles, the lights came back on. I decided to replaced the TCM unit with Mazda's latest version and the car has not experienced any transmission problems since. While the Mazda 3 was in for the transmission repair, the mechanic noticed that there was oil leaking from one of the front struts. Both struts were replaced and alignment performed. Transmission problem was not resolved by the work performed previously by the repair shop. Transmission problem returned 3 days after transmission solenoid was replaced. I replaced the transmission ECU and reset the the main ECU by letting the car idle for 20 minutes. This successfully resolved the limp mode transmission problem.

Replaced the old TCM (Transmission Control Module) with a newer version. A CEL and AT light were intermittent - The transmission would go into 'safe' mode and would not shift properly, or it was a harsh shift 1st and 3rd gear only. Shutting the engine OFF and a restart would sometimes cure the problem. This is a common problem with this car, and can occur anytime. AT warning light on /off intermittently. The dealer wanted $5k to rebuild the transmission. Studied a lot of Mazda forums on the internet, and determined the problem was the TCM, but a replacement part from the dealer was $750.00 + HST and labour to install it. I managed to get a new current one from Scarborough Mazda for $550.00 + HST and 2 hours of my time to install it - plug 'n play. Problem solved - it ran and shifted like a brand new car! Mazda has to be aware of the TCM problem by now, and should have issued a TSB to cover the situation, so dealers and their technicians could accurately diagnose and repair this obvious 'long term' reliability issue.

The forward shield is made of a heat resistant material which is sandwiched with foil. The existing shield had worn over the years and broke off of the fasteners.

Car has a low idle (around 500 RPM) and shakes and almost stalls at red lights, once the engine is warmed up. The Mazda dealership cleaned the throttle body and replaced engine mount #3, at my expense, with NO improvement in symptoms. Follow up visit for my low idle/shaky idle/almost stalling at red lights, after I paid them good money to diagnose and fix the problem. They claim the idle is just fine and there is no problem. Roll Eyes. Useless Mazda dealership! The car would intermittently not start when in Park, and you would have to shift it into Neutral to start it. They claim they adjusted the shifter cable, for $70, and now it does reliably start in Park.
