   My screen begins to change the display without me touching it. It has interrupted my GPS directions, causing me to get lost. It has gotten worse over time, now causing my back up camera to either not display at all or become partially blocked by another application randomly starting on the screen. My emergency brake lights flash on my dash, and auto technicians tell me it is a malfunction with the electrical system, not something in my brake system that needs to be replaced.…

   I noticed smoke filling the inside of my car. I looked over at the passenger seat, and my coat was on fire. I poured my drink on it, pulled over, and threw the coat out of the car. I saw a large hole in the lumbar area of the passenger seat, and it was glowing red and putting out a lot of heat. The seat heater was on, so I immediately turned it off. It was obvious that the fire has started inside the seat, and there was no other fire source in car--ie. lit cigarette,…

    The info uni in the car constantly resets itself. It happens when GPS is activated, parking, listening to directions, pretty much at all time especially in crucial moments. Nav center doesn't even load at times, this causes unknown information of speed limits and streets.

    The used 2016 Mazda CX5 I just bought apparently has the "ghost touch screen" where the Infotainment system will randomly pick controls, place phone calls, change navigation. How can this not be a safety recall? I'm afraid to drive this car and not have full control of the navigation system or controls. This is DANGEROUS to have this happen when driving!! Mazda should be held accountable for this clear safety problem.
