Okay so my wife bought the 2010 Traverse LS, and was happy with the deal we got... While playing with her new toy, I openned the little storage compartment in the rear of the vehicle, and when I went to check what was under the little square cut out (spare tire release bolt) and noticed it was soaking wet... I'm not talking about a little damp, we're talking about squeezing out dripping water. The following morning, we take it back to the dealer... long story short, there is a weld under the rubber seal on the back door that was not completed, so everytime it rained water would leak in between the outside and the metal inside so that you can't see it and all the way down. Being that these vehicles are made with robotic, I'm sure that our vehicle was not the only one with this issue.... So you might want to check to make sure you don't have an issue.... It's fixed now and the wife is happy again, and that is all that matters.
