GMC please take accountability for the sunroof leak issue! Years of data, almost 100 complaints, someone should already know about this and have a solution! My car has serious leaking issues from the sunroof above the driver, electrical to cabin doesn't always work except dash lights, and headlights/turn signals work sporadically. The locks work when they're in the mood. Also means ac/heat works sometimes..I live up north and it's 24 today. My windshield wiper fluid remains empty because it randomly turns on and drains out: which also means replacing my wipers is a bad idea because they randomly turn on for at most an hour and dry wiping the window...and destroying the wiper blades. All wheel drive won't work, despite mechanic seeing no issues. I've taken down the mounts and tried to flush the draining tubes myself..and they're clear with no leaks when I tested the tubes. …
