I was more after the principle of the matter that a brand new truck should not be leaking. I didn't want to have an issue down the road of a wiring harness or something not working because it had had water in it at some point.

Good morning, I have read many posts about the roof leaks from the XM antenna and wanted to share my experience and what the dealership did to correct it. I was driving doing the normal routine when I noticed water dripping down from the head liner. Took it in and of course dealer says this happens all the time and that they would replace the xm antenna and send me on my way. I told them that was un-acceptable as its a brand new 2016 3500 High country Duramax and a 70k dollar truck should not have these issues. Told them I wanted a new XM antenna ( which they claim is a new design from factory and corrects leaking problem) new headliner, new wiring harness up top, new sun visors and new over head center console as all had water in them. Tey said that is not normal procedure and they would have to get it approved. While waiting for approval they say that I can pick up the truck and drive it until a decision is made, I explained that if I were to have water drip in my face and crash while driving that it would be a pretty easy scenario to hold Chevrolet/dealer responsible. They agreed and kept the truck and gave me a 2017 1500 that i was not aloud to use for towing so they had to give me an enterprise commercial truck as well so I could tow my car hauler. Eventually they get approval for all parts to be replaced ( after about a week of waiting) and ordered parts. It took another week for the headliner to come in because it had to be pulled from the production line according to the dealer because this was not standard procedure. Three days after parts finally arrived the truck was done. Now i thought after waiting 2 and a half weeks for a water leak repair they would at east wash the truck before i picked it up but id be wrong in assuming that, it was greasy inside, dusty and dirty outside. All in all got everything replaced and hasnt leaked since although its only been a week. Its a shame that GM has such a need to save 10 cents and let it cost them thousands on the back end... I read some people were having trouble getting GM to replace the headliners and I think the most "forceful" you are with them the more likely they are to replace it.
