Just an FYI, if you're looking to buy one of those vehicles soon.
GM has issued a stop-sale order for 2009-2014 Acadias/Traverses/Enclaves. There is an issue with front seat belts that can result in failure (in addition to a previously announced recall for driver's side airbags). You can buy the vehicle but can't take it home until repairs are made - unfortunately GM has no timeline for repairs and acknowledges they don't even have the parts.
As a comparison, I took my Acadia to the dealership 5 weeks ago and they ordered the side airbag part for me, quoting a wait time of a week. The part is still not available and now I have to deal with the additional recall. With the millions of cars they have recalled lately I don't expect anything to happen in any reasonable time frame.
