2021 Silverado leak is in the passenger side rear, same spot before the tsb was preformed. location B.C (rain forest ) built in september of this year, developed a leak three months after purchase. had the tsb done now a month later is drips in the rain but not if i were to physically hose off the roof. i have a app booked for later this week too see if the dealership can fix it again. if anyone knows of a contact for gm Canada, it would be great if you can share. i just want my truck to be leak free i really don't enjoy going back and forth with the dealership. Thanks Dan,
