Had the sealant repair in August (took 2 weeks) and leaked 3 days later. Took it back and took another 2 weeks for replacement window + sealant. Because so much water flows under the spoiler and dumps right on top of the window, I asked them how we could build the sealant up to where the water sheds off the top instead of sitting behind the window on the seal. They talked to GM and realized they were doing the repair incorrectly, and it looks like they did what I asked (although it looks a little messy). Also, I've been following this thread a long time and have seen many pictures of window frames posted. I have never seen a frame like the new one in my truck. They insisted this is THE new window design to address this issue. I have been told a few things that I know are untrue, so who knows but see below and take it for what it's worth.
After this mess, I have sold the truck to to a dealership for $500 less than what I paid in April with 5,000 miles on it (thankful I bought when they had 2x $6,500 discounts). I don't want this headache anymore. I keep my vehicles a long time and I refuse to worry about a leak every time it rains or I wash it.
Hopefully these pictures below help someone. I included the receipt from the work. If anyone knows anything about this window, please let me know. I am curious if it really is a new style window. (Keep in mind, I think the part number is the glass part numbers, not the window assembly part number). Good luck to everyone.
