For two weeks leading up to the 3/27/14 incident, every time we started the car the air would not come on and we would have to manually turn the air on. When we turned the car off, the air would stay on. Two weeks later, when I was operating the vehicle, the gauges on the instrument panel started going haywire displaying dozens of messages, and the all of the gauges would shoot up, then bottom out at 0, then shoot up again, etc.. I turned the car off, and when I came back later to start it, the car wouldn't start but the electrical stuff came on. After several attempts to get the car to start, I roll down my windows and then try it again, and the car started. I drove it straight to the dealership. The dealership replaced the body control module and some wires and said they fixed the problem. Less than 48 hours later, the same thing with the gauges and warning lights happened. We immediately sent an email to the service department since it was the weekend and they were closed. On Monday, the car died again, but the radio kept coming on/off....I fiddled with the radio and the car started. I drove it straight to the dealership. They can't get the car to "mess up" again, and are waiting for it to do the same thing it did for me, so they can figure out how to fix it. I am concerned that the car is showing significant electrical problems that include safety equipment, yet GMC is ready to turn the car back on the road. Note: All recalls are up to date and the dealer has been in communication with GMC.

My 2011 GMC Acadia (denali) has now been taken into the dealership 3 times (and likely an upcoming 4th) due to the right front power door lock and window (and rear hatch) working intermittently over the past year. They have tried to replaced the door module and reprogrammed it. The next time, they replaced both the male and female terminals in the connector and applied some grease. Not exactly sure what they did the third time. My concern is that it just happened again although after 24 hours it was fine. I understand GM currently has a recall out for SUVS but for more older vehicles = fire, smoke, other are linked to electrical problems with the door unit. Just wondering if my vehicle is having the same issue even though its 5 years newer. There has been no recall on my vehicle as of yet.
