I had to have my car brought in for a check engine light. After the dealer did a full test, they narrowed it down to the gas tank area. It was a fuel module broken at the flange and also they recommended the fuel sensor to be replaced because they have been noticing a lot of vehicle coming in with the sensor going bad. The dealer also informed me that the 2008 Acadia's have a design flaw in the gas tank and there is a chance in the future it may need to be replaced, but for now the tank looks really good.

Bought vehicle with only 23K miles on it, transmission started acting up within 6 months of driving it, taken to a dealer, said nothing wrong, another year later got worse, took it in to a different dealer, nothing wrong, 6 months later took it in before going on vacation, nothing wrong, but had problems while on vacation, 6 months later, 1,500 miles away from home on vacation, driving down a 75 mile an hour speed limit divided highway, transmission went out with no warning, no dash warning, took in to a transmission dealer (since we couldn't get into a dealer) and said we wouldn't make it home the way it was. 5 grand later and a mess of a vacation later we were on our way home. Less than 3 months later, tighten gas cap light on dash, check tire pressure light on and check engine light on. Found out online that this model and make and year had numerous issues with transmission, don't understand how there was no recall and how GM got away with it. Oh, and we were under extended warranty in the beginning where they said nothing wrong, and as soon as warranty was expired, boom! transmission had to be fixed! transmission dealer said the damage was from a cheap $15 part that caused us to have to spend 5 grand while on vacation. We have all shop paperwork showing the paper trail what we tried to get fixed.

This is the second time I have had the same issue. I am driving the vehicle and the transmission does not shift out of 2nd gear. The check engine light comes on. I have the vehicle repaired once for this issue. I was told it was the valve body the first time and it was replaced out of warranty.
