No go, dead the dash lights light up but the starter will not engage. Towed to dealer, 1st they says its the engine computer, then its the, transmission computer.

I parked at the top of my driveway at a slight incline position with the emergency brake engaged and the car was in second gear (manual transmission). It was in a stationary position at that time. My family exited the vehicle and we went inside our home. Approximately a half our later I notice my car rolled down my driveway and crashed in between two trees on my property. Either the emergency brake failed or the car's transmission failed while parked. The car was found at the bottom of my property still in gear and had the emergency brake in the engaged position.

My car twice in one day shifted out of gear and became unresponsive when I tried to use the accelerator. I was on a surface street making a U turn the first time, and had made a right turn the second time. I took it to my mechanic after the first time it happened. He told me it was the module in my automatic transmission that was sending a faulty signal. There is a recall for other 2016 Mazda 3 vehicles for this problem, but my VIN isn't included, so a Mazda dealer I called refused to fix it unless I paid for it.

This vehicle cannot tolerate even the slightest bit of slush or snow or ice on the road. The wheels start to spin and it goes nowhere. Many times in light wintery conditions, the vehicle failed to handle the winter conditions, especially on any kind of an incline, and my whole county is located on one big incline. This vehicle is supposed to have full time traction control. That's laughable. On the slightest incline with 1/4" of slush on the road, we were forced to turn around and take a route that is flat. The car just cannot handle it. I cannot give it to any of my daughters as they all live further North than we do. It needs to go to a Florida or Texas or California owner.
