Vehicle was inadvertantly turned off while in drive, when parking the vehicle no alarm sounded. Upon exiting the vehicle, the vehicle began to roll backwards, forcing me to jump back into the car and jam on the brake. One would think that as a safety measure, the car would be required to be in park, before turning off the engine. While its conceivable that in an emergency the driver may want to turn off the vehicle while in gear, this would be very rare, and could be accommodated by programing the off switch to require multiple pushes or holding in the button for an extended period. Exiting the car when it is not in park is a dangerous situation, just as dangerous as trying to start the car while in gear, resulting in unexpected movement of the car. Since the car requires the gearshift to be in park and the brake on before starting, one would think a similar process would be used for turning off the vehicle.

The day was hot and I was in stop and go traffic with the ac set to 72 degrees in my 2015 Mazda 3 with just 21K miles on it. My car unexpectedly stalled and the check engine and charging system/battery lights came on briefly in the dash. I had to shift into park and push the button to restart my vehicle. The car's ECU/PCM did not set any codes and the problem has not occurred again since that hot day. This is a danger because the sudden loss of power could result in a rear end collision luckily I was in stop and go traffic. Dealer and Mazda have been slow to investigate this thoroughly. Feels like they just want to send me on my way without doing a thorough investigation of this issue.
