This all began at about 75000 miles. It first started with the stabilization/traction light coming on while driving once this happened you could not accelerate the car. I once was on a highway in the middle lane when it happened I could not accelerate and had to try to get over to the break down lane. This happened several times but then turned into a completely different problem. While driving the battery would start to die with no warning. When this happens you can not jump the car you have to bring the battery to be charged on a charger. Although the car won't start the other things like lights, radio, etc will still work. This happened several times but once the weather was warm it ran perfect for 4 months. The first day it was extremely cold the battery died while driving. I also had a headlight go out on the drivers side and about 3 weeks later it came back on and stayed on. I have brought it to several places but nobody has been able to figure out the problem. I can't keep spending money to get it diagnosed with no results. After researching online it seems to be a very common problem in the Acadia.
My 2011 GMC Acadia suddenly drained the battery, I tried to start it and didn't work, the battery was dead, so I replaced the battery with a new one, the next day the new battery was drained like the old one, so I took the battery back to autozone, they checked the battery and was nothing wrong with it, they also checked the vehicle for any possible problems and the diagnostic didn't show any problems, so they replaced the battery again with a new one,. . . So I had the new battery installed on my vehicle and went home, the next morning when I tried to start the vehicle the battery was dead, I went online and found forums talking about the same problem, I bought this vehicle for my wife and she got very dissapointed for having this issues with the vehicle, it's the first time that we purchased a GMC, we had always bought Ford vehicles, I called GMC and they don't have any reports with this type of problems but there is a lot of comments on internet from people suffering the same situation, . . . . . I don't know what to do, and can't keep changing the battery everyday to be able to use my vehicle.
