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..

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.

Even though it says it can use the lowest octane rating, I noticed some hesitation when starting from a red light. The cure for this was to go up one grade of octane now no more hesitation.

The brand new car idles very rough at stop lights. It shakes the entire car.
