I bought 2007 denali on 8/15 and it had to go in for repair 8/17 because the engine hot/ac turned off came on. Got the car back 8/20 at 7pm and 8 am the next morning 8/21 the same message came up on the dash board. I was told it was ok to drive until I could get it in for repair again on 8/22. Tried to start the car on 8/22 and the car wouldn't start. I don't feel safe in this vehicle at all and would like to get a brand new truck as since I am paying $48,000 for the truck.
