My RPM'S reaved up real high while driving 60mph and all the sudden the car down shifted and I had to put car in neutral in order maintain control. The traction control light and heck engine lights came on same time, lost power to the car the navigation and radio and dash lights, had no power to drive train, had vechile dinogstic check done at O'Reilly auto and they told me it was a PCM power control module. And I called the mazda dealer in Fostoria ohio the macanhic told me the PCM power control module had been reprogram and I never received no notice on any recalls or the person I bought my car never either. My car is 7 years old and if it war reprogram it should not go bad that soon. Unless there is a problem with there components there using. But my car will cause a accident if I continue to drive it. I like my mazda6 2015 but I'm afraid after having the car doing what it did to me on the highway. I had no warning lights come on until the day I was driving down the highway when this problem occurred.

On Nov 27 16 the following safety issue occurred to my auto. While driving about 20-25 mph in slow traffic my vehicle threw itself out of gear, the engine raced, after a couple of seconds it violently went back in gear. Prior to this happening the transmission had locked up twice and the auto could not be moved. By turning the ignition on and off that lock-up was freed. During this same driving period the following malfunction lights illuminated intermittently; engine light, low tire pressure, air bag, traction control (repeatedly). The autos engine was missing intermittently running rough. Operating conditions: Ambient temp: 78F, no wind, dry roadway, no precipitation. I contacted manufacturers Mazda assist, they requested towing, auto is now at the dealer in (wallace) in stuart, Florida, I informed Mazda assist that I considered the car unsafe to drive, as I am handicapped and the holiday traffic was totally jammed I was force to drive slowly home on the 20 mph fla turnpike..

Automatic transmission failure occurred as follows: Transmission disengaged while driving 35 mph in city traffic (taylor street, columbia SC). Car lost power as if the transmission was in neutral. Warning displayed on dash "ats failure." I powered off the engine and re-started engine and drove approximately 500 feet before transmission failed again. Was able to drive to the Mazda dealership after 4th attempt. Technicians labeled the issue as a "fluke" and they could find no reason for failure, although they did verify the code P0780 which stated to re-program the transmission. If I had been driving on the interstate (which I had been earlier in the day), the consequences could have been much more serious.

Was following a car and came up to a stop light. I depressed brake pedal and felt some resistance but car would not stop. Felt like the brakes were being bled off by perhaps computer control. I switched into a right hand turn lane that was clear, car still not stopping. Shifted into neutral, and engine started to rev up perhaps to 4500 RPM or so, then engine went back to idle on its own. The car had stopped and I put it in park. We then turned right and cautiously proceeded home, without a further problem. Took to dealer and requested the memory be analyzed, they said they could not read the black box at the dealership. It showed no faults. Test drive was uneventful. I again requested the black box be analyzed as the brakes appeared to be bleeding off. They said they would let me know if Mazda needed anything more. My background includes auto mechanic, tow truck driver, car dealership, technician, software engineer, and analyst.
