No such luck. They told me is was fixed under the 3/36 and I'm at 39k so they won't fix what they were supposed to fix right the first time. Guess they don't stand behind the warranty work. Was less than a year ago. Was advised to call GM to see if they would open a case and fix it. Doubt they will. I'd hate to be the High country or Denali Ultimte guy with a leaky truck. Went thru this in 2019 when the new body style came out. Twice....It's unreal this is still happening to these high dollar trucks. Oh well. Been watching YouTube videos on self fix. Taking the rear headliner down makes me a little nervous but if I do at, atleast I'd seal everything up better than the last time the dealer did it. GM.... Fix your leaky trucks... @GMCustomerService
