Scenario 2: while driving, the audio and engine will shut down briefly (<1 sec.) and turn themselves back on. Warning lights like the tire pressure light will flash red briefly; the triangle with exclamation mark in middle light will also flash; the RPM gauge will dip, the fuel gauge will dip quickly to empty before snapping back to the normal level. All dashboard activity will flash then come back on. The last occurence left me having to restart the car

Anybody ever experienced this? Any minor troubleshooting I can do before taking to dealership?
