Window/Roof Leaks

[Ducky]

Not sure I posted on here but shortly after I bought my truck, I had a wet headliner and puddles on the floor and wet dash from rain, originally the dealer thought it was the sharkfin and replaced it, still after another rain it leaked again. They ended up replacing my windshield which so far over a year have fixed the issue. Fastforward, my Dad who also has a 2017 felt water on his legs, felt under his dash and there were pools of water, when he called it in to both GM and Dealer, GM told him to work with the dealer, and the Dealer said, they know it's the windshield and so many people are coming in for repairs that he's going to have to go on a list. About a month later, The dealer called him in, his appt is tomorrow. This was just to try to help those who had similar issues on what to expect. Now I get to wait to see what the fix for the rear defroster canada issue brings us in the USA.
