Chevrolet Silverado 2500 water leak problems

Filed Feb 10, 2026 · Body · MO

It is a very well known issue with these make and model trucks, ( 19-current Silverado 1500,2500,3500) that the eurethane on the back glass and the back glass track/frame cracks and leaks water causing an unsafe environment inside the vehicle if not caught. There is little to no visible evidence this occurs unless you really look and or take apart the headliner and rear spoiler on the cab to search for this issue. Water intrusion into the cab of the vehicle can build mold / mildew and cause a severe health issue for occupants inside the vehicle. Gm has a TSB out on this issue and I believe it should be a recall as there are thousands of trucks out there with this issue risking a respiratory issue to those inside the vehicle.

Water leaking in around rear window causing moldy smell, puddled water on rear floor, saturated carpet. Believe to be health hazard because my eyes & nose burn when I’m in the vehicle. Have not had any inspection of this problem because the warranty had run out before I discovered. This is a known problem to GM on numerous trucks as I learned after researching. Truck has very low mileage, less than 15000. Very disappointed.
