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.

MY VEHICLE HAS HAD STRANGE GRUNTING, SQUEAKING, POPPING NOISES COMING FROM THE FRONTEND, PARTICULARLY THE DRIVERS SIDE. IT HAS HAD THIS ISSUE SINCE I BOUGHT THE CAR IN JUNE 2017. THE NOISE SEEMS TO BE WORSE WHEN DRIVING OVER SMALL BUMPS. IT'S VERY NOTICEABLE WHEN I BACK OUT OF MY DRIVEWAY. I HAVE ADDRESSED THIS ISSUE WITH THE DEALERSHIP I PURCHASED MY CAR FROM. THEY CAN'T DUPLICATE. I HAVE RESEARCHED THIS EXACT ISSUE AND FOUND THERE IS A TSB FOR THE SUSPENSION ISSUE I'M DESCRIBING. I'M JUST GETTING WORRIED ABOUT MY SAFETY. I'M AFRAID SOMETHING WILL FAIL AND I FEEL IT'S THE MANUFACTURERS RESPONSIBILITY TO CORRECT THIS UNSAFE ISSUE WITH THE SUSPENSION THAT AFFECTING MANY OTHER MAZDA 6 VEHICLES.
