problem #1

Nov 072018

Sierra 1500 Denali 6.2L V8

  • Automatic transmission
  • 653 miles

Just had some bad storms move through my area. I went to pick my child up from daycare and as I was getting him into his car seat I noticed that my entire back seat and all my contents where soaking wet. I looked around as much as I could with a 3 year old's help to locate the leak. As far as i can see it is leaking from the top of the rear glass by the sliding glass rail. I know things happen on newer body styles and really just wanted other owners to be aware of the issue so they can get it corrected if they have the same problem. I have not dropped it off to the dealer yet but i will update this as soon as i hear something.

Update from Jul 1, 2019: Rear window was leaking and dealer had to replace it.
