Vehicle ignition randomly doesn't start and/or vehicle drive strange with traction control and or transmission acting weird. After 5-10 min, I turn off vehicle and restart and it operates normally again. Dealer has seen on multiple occasions and can not explain the problem.

The check engine/service stabilitrak/engine power reduced light comes on frequently yet the GMC dealer cannot pinpoint the problem. Potentially a connection to recall of cars equipped with heated windshield washer fluid feature. Did detect a slight odor shortly after using the windshield washer fluid and the indicator lights started flashing and the car slowed down considerably on the highway during inclement weather. Thus far nothing has corrected the problem; we are hoping to get the car back to our home state so the dealer can work on resolving this hazard.
