A window leak in the 2019 Chevy Silverado can be attributed to two main factors. One possibility is that the window is either loose within its frame or it has a visible crack. While a crack is usually easy to spot, a loose frame may not be as immediately noticeable. In both scenarios, water is able to seep through the gaps caused by these issues. Another common reason for a window leak is when the sealant around the window becomes torn or deteriorated, creating a pathway for water to enter. Additionally, a telltale sign of faulty sealant is a whistling noise while driving due to air passing through the gap. Fixing the sealant can be done using a DIY home kit, but if the window is loose or cracked, it may need to be entirely replaced.
I've experienced issues with three windows leaking on my 2019 Chevy LTZ Silverado. It's not due to the seal or a loose frame, but GM has attributed the problem to excessive body flex causing cracks and failures in the plastic frame of the electric sliding windows. The problem occurred at the thin part where the sliding frame narrows down. During the most recent window replacement, the affected area was relocated just behind the trim pillar to conceal it from view. Despite this change, water was still found on the back of the seat and the second headliner was stained.
The reason for the leakage in the back window of the power sliding windows is because the plastic window frame cracks at the thin end of the sliding channel. I've had a truck where this happened to three windows. While GM hasn't directly confirmed, the dealership mentioned that GM believes the excessive body flex is causing the cracks in the plastic frame.
I own a 2019 Silverado with 14500 miles on it. I discovered a leak near the rear window on January 8, 2023, and took my truck to the Chevrolet Dealer the next day. The service advisor informed me that the problem was a cracked rear window frame, a known issue affecting many vehicles due to excessive body flex. Although there is a Technical Service Bulletin from GM recommending sealant as a solution, this dealer suggested replacing the entire window because they believed the TSB wouldn't be sufficient. I reluctantly scheduled an appointment for January 11 to have the window replaced, which cost me $975. On January 10, I lodged a formal complaint with GM and was provided with a case number and a Customer Engagement representative. When the dealer informed me that my vehicle was ready for pickup, they mentioned that GM had reached out to them and offered to assist with the bill. To my surprise, GM covered $600 of the total cost, even though my warranty had expired in March 2022. The dealer advised me to keep the $375 receipt, anticipating an official recall where any expenses would be refunded.
I applied flex seal all around the back sliding window and sealed the opening near the roof light. This fixed the water issue, and then I sold it to a dealer!
I drive a 2019 Chevy Silverado high country, and my rear window is also leaking. Chevy really needs to step up their game. It's been more than a week since I contacted customer service, but I still haven't received a call back from a dealer.
I have a 2019 Trail Boss LT with 100,000 miles on it and a full warranty until 120,000 miles. The GM dealer is refusing to cover the replacement/repair I need, claiming it's not included. This is ridiculous! There is mold under the floor mats due to a leak at the rear of the truck. GM should address these basic issues and provide better training for their dealers.
Just a month ago, we paid $600 to a car repair shop to repair a leak. Only last week did we realize that the leak has now spread across the entire back window, instead of being limited to just one corner. I'm at a loss for what to do next.
I own a 2019 Silverado RST and I was informed that fixing the issue would cost me $800 or more, but not exceed $50,000 with an extended warranty. However, the back window problem is not covered by the warranty. I'm unsure how to proceed.
I purchased a 2019 car and had to take it to the dealership three times for repairs. The third time, they ended up replacing the entire glass. Now, as I'm typing this, it's raining outside and there is some water on the passenger side near the sliding rail, even though there are no cracks. I am fed up with dealing with this water leakage issue.
An old or damaged seal is probably the main reason why water is getting into the back window.
