Wiring problems of the 2019 GMC Sierra 1500

My 2019 2500hd (49,00 miles) truck had water leaking in through the roof. The dealership found that the leak was caused by a bad factory tack weld on the passenger side roof seam. Due to this bad tack welkd, it caused water to leak down the a-piller, down into my electrical fuse box and wiring.
