Bought new in 2015. Infomat system reboots 3 or 4 times when temperatures are below 40 degrees at start up in a unheated garage also while driving and cold engine light is still on. Took to dealer a couple times, and informed them of the problem while still warranted, all they did was reboot the system. Still doing it after 4 years. Very frustrating, but now it's on my dime. One time it went completely black, so I figured out how to reboot it.

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.
