Water leaks into the cabin by model year
What owners say
The track on the back glass is cracked and leaking water into the interior back cab light.
Rear power window has been replaced multiple times, each time it develops cracks and leaks water causing possible mold in the truck cabin.
There is a water leak from the rear roof leaking causing water to come inside by the rear window down the rear pillar by the airbag. May cause problems with the rear side airbag and mold. Dealer charged me a $273 diagnostics charge and will not repair under warranty or extended warranty even though there is a TSB on this affecting numerous other trucks
rear third brake light is leaking water into the cab and causing water stains on the headliner. I am worried about it eventually causing an electrical short or more water damage. I don't have a rear window that slides open and the rear glass has never been replaced nor has the third brake light all original from factory.
