Dropped off my '19 LTZ Z71 for the third time on this issue this week.
1. initial leak on drivers side corner, removed spoiler, applied sealer, did a $hitty job with sealer on window and plastic trim and paint, leaked much worse on first hand wash
2. replaced headliner, resealed window, cleaned everything - leaked on passenger side after 2 weeks just sitting in driveway
3. back in the shop, no word on the plan yet
Love the truck but really disappointed in this issue.
