2019 Chevrolet Silverado 1500: water leaks into the cabin

Filed Oct 9, 2025 · Electrical, Visibility · NC

The back windshield on my Silverado leaks water every time it rains causing the back window to smell of smoke like electrical burning. It also creates a visibility issue out the back window when I've called three different dealerships in the area and each one of them say it is a known issue with this vehicle and it's going to cost almost $3,000 to fix. I have contacted GMC only for them to say that I needed to contact this department I feel like this is a safety issue that GMC should have to help their customers with not just be like oh well your truck may or may not be on fire while it rains

Hello, I purchased a 2019 Chevrolet Trailboss LT from a Chevrolet dealership on April 23 2024. I noticed a few days later and after the first rain, the back window was leaking water inside. There is a service bulletin regarding this issue, I called General Motors and was told that they recommend me getting this repaired at my expense. Ironically my mother whom was with me at the time of purchase was coughing on our way home from the dealership and said she’s very sensitive to black mold and felt the truck had mold somewhere in it. I do have pictures of large water stains on the headliner along with water running down the back window onto the carpet. I do not feel comfortable putting my family in this vehicle with possible black mold. At time of purchase, i mentioned to the sales lady that my mother suffers from a chronic lung infection and the leaking back window service bulletin was never disclosed with me. I feel that General Motors should be held accountable to make these repairs at their expense due to black mold, water around electrical and seatbelts. Thank you for any help

The rear sliding window structure is faulty and this is well documented through complaints. The structure surrounding the rear sliding window is not strong enough to stand normal wear and tear. This is documented in [XXX] . The supplier produced poor quality material. Was it the suppliers fault or GM's specifications? The water leakage can cause damage to the rear seat and floor board which can cause mold and mildew to form, causing a health issue. This happened to this vehicle. Because of this known problem which GM gets away with the consumer has to foot the bill. The dealership has to send this truck out to get fixed and the cost is around $900. Though the mold and mildew is not enough for a recall since it is not a safety issue. It does become a safety issue when the water interacts with the electrical system and causes it to short out and cause smoke. This happened to my son's 2019 Silverado Z71. The safety issue is when a child is strapped in their car seat in the back seat and this happens. Which happened in this instance.

On November 14, 2022, I noticed Water leaking in Rear Interior of Cab, Water Leak at Rear Sliding Window. It is clear that it had leaked before as there was several noticeable stains. I took the vehicle up to the Chevrolet dealership in Frisco, Tx to show them. They stated it was a known problem. Another Chevrolet Silverado was next to mine that they said was there for the same reason. [XXX], the service technician told me it was going to be in excess of $4000 to repair. I do not have an extended warranty and the vehicle is outside the standard 3-year warranty.

There was an the federal safety agency bulletin issued in August 2020 for this same issue. The bulletin number is 18-NA-383. The vehicle should be recalled and the issue fixed by Chevrolet since is is clearly a defect in the manufacturing process.

Back window on truck is leaking water. Headliner is discolored and its very close to an airbag. I'm hoping its fixed before the water sets off the air bag accidentally. First dealer fix resulted in a bigger leak than original.
