While using the phone in acc mode for 10 mins. I had system failure warnings for the; brakes, abs, traction control, tmps, and power steering. According to the dealer, with the nature of the car with most systems except drive running off of the small battery, 10 mins of acc mode caused a low voltage situation tripping the warning lights for nearly every system on the dash. I assumed that they would reset by starting the engine and powering the battery, but instead they must be reset by a scan tool. I am waiting for a open slot at the dealer
