My GPS system went out on 2016 Tahoe. The shark fin antenna has a weep hole on the back side and the roof slants which allows water to get inside. Now when it rains my the headliner inside gets soaked and water leaks onto center dash. Anyone else have issues?

Shouldn't this be a covered defect? Tahoe has 68,000 miles. I have owned 1999, 2002, 2007 Tahoes and it never rained inside these?

 

I had the same thing on my 2015 Silverado HD2500. My dealer fixed it when it was 6 months old but balked on doing anything about it when it happened again this year. I told him to find a parking spot for it as I wasn't picking it up. They relented after a day went by and covered it under a replacement of antenna warranty. I was quite done with Lou Fusz Chevy and will never buy another new one again. I did just pick up a 2008 Suburban LTZ in like new shape but despite lifelong frequent oil changes it has the dreaded Stabiltrak-Engine light. Probably needs new lifters. Glad I bought a warranty.

I sold my HD a few months ago since I never move my 5th wheel anyway. Now I own a hybrid to go back and forth and the Suburban when I get there to launch boat.

Good luck...
