I just bought this 2010 Terrain used it has 57K miles on it. WE have had it for about 2 weeks with no issues. But yesterday while driving home all of a sudden the a/c would shut off, gauges would go crazy, and some warning lights would pop up. After a min it would all go back to normal then 10 seconds later crazy again. We got to where we were going turned car off for awhile. It started again while I was driving. Got to our 2nd destination turned the car off. When we got back everything was fine and has been so far today. Has this happened to anybody else, any clue what this could be?
