Brakes

Transmission & drivetrain
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. …

Windows, wipers & sunroof
I had done tons of research and finally found the vehicle that I was wanting. I purchased a brand new Mazda6. I had only had the car about a week and a half, when suddenly, as I was entering onto the highway, I got my speed up to approximately 35-45 MPH when I heard three loud pops. I saw my windshield beginning to split from the seal at the base. It split central above my defroster. By the time I traveled two miles to pull over, I had watched the crack grow, forming an s shape onto my windshield. When I contacted the dealership, I was immediately advised if it was a rock chip, it would not be covered. There was no rock chip on my windshield, I looked at it and took pictures of it. By the end of the day when I had gotten off of work, the crack had grown, covering about 1/3 of the height of my windshield. …
I am the original owner of a 2015 Mazda 6. While traveling on a straight 60 MPH highway, my sunroof window suddenly exploded, with a loud "bang!". The window was closed at the time and had not been opened in approximately 3 days. Fortunately, the interior deflector (sliding cover) was closed at the time, or glass shards would have rained down on my face and hair. No objects or sudden motions provoked the explosion. Police would not write a report because there were "no suspects of vandalism" and "no collision with other vehicles or property". $725 later, I have a new replacement window from the manufacturer and hope for no similar future incidents or possible mold/mildew issues. The cause of the safety risk is unknown but is certainly unacceptable, given that I maintain my vehicle to the highest standards and am the original owner of only 3 years. …
