2011 Dodge Durango stability control problems

Driving about 1 mile and air conditioner by itself went to a lower speed, kept driving for about another 10 miles and proceeded to get on freeway when did so, drivers seatbealt flashing that was not buckled then all the lights on the dashboard were flashing and the air completely shut off. It was hot so proceeded to row down windows and was not able to, almost like lost power..

My 2011 dodge durango engine shut off while driving. The first two times it happened exiting the same exit on a right sharp turn at the same part of the turn. The steering wheel locked and I had to force all my weight to turn it and pull off to the shoulder avoiding getting hit from behind and the side. Dodge dealer claimed nothing was wrong but wanted to keep car to investigate. I filed a complaint and opened a case number with chrysler corporation.
