Ok Reading this forum makes me wish I did not buy this Leaky Boat. Back in 2015 we ordered this truck from the factory custom this and that including a sun roof. We accepted the truck in good faith, paid $ 70 K Cash.
This truck is used primarily as a comfort ride (which it is) for long distances. Then we noticed the passenger seat belt, belt was wet after a rain storm. I figured it rained so what. Fast Forward to a couple of weeks ago when we had a lot of rain. Now the truck is usually on an up hill incline and we normally only have 1 driver and no passenger. So I parked it at my factory and after a day of working I walked out and noticed a water stream coming in from just in-front on the passenger window visor. I then noticed the weather passenger Tech mat had about a 1/2 " of water on the passenger side and the headliner was wet just in front of the passenger headliner bracket. I took pictures. We called our dealer and he said he would take care of it. Later after the dealer serviced the truck he told us the drainage tubes were blocked and they had cleared them. (We never use our sunroof it might have been opened 2 x. I was able to insert my finger in the roof liner and passenger sun roof, my finger came back dry). Anyway fast forward a week later and the truck has been sitting on an incline. The seatbelt is soaked, thanks GM for taking my truck for a day and what i gather will be another day and then another as I have no confidence that your organization has a clue on how to fix this.
