2020-2023 GMC/CHEVROLET REAR SLIDERS LEAKING

Yesterday I had a customer bring his truck in to put tint on a new sliding back glass that he had to have replaced at the local GM car dealer because it was leaking water. The plastic cracked on the origional one which allowed water to come inside the truck. I had two used and recently purchased 21 and 22 GM and one Chevrolet pickups in here that I decided to look at closely and sure enough, they both showed signs of water leaking from the tops of the rear sliding back glasses. I even squirted water from the outside and discovered that the water easily ran down on the inside of the trucks. Just a heads up to maybe inform your customers who are unaware that their truck windows are leaking. 

The manufactures know they have an issue and admit that the plastic was inferior that was used to make the sliders but will not be issuing any recalls. That means it’s up to people to discover the leaks on their own and hopefully get them fixed if they are still under warranty.

This is just like the 2015-2018 GMC/Chevy door panels with defective vinyl dye.  Everyone argued with me that it was the solutions we are using    

 

Thank you for the heads up on this

I've also seen a few Rams leaking from the third brake light. Foam gaskets breaking down. Was told to keep an eye on the air flow vents at the bottom/rear of the cabs.

Their panels are the worst to remove, even the new ones. Id rather remove panels on an Audi. Chevy lost it way. I never tint their stuff because nobody buys it.

I worked at a chevy dealer and these are known for that but the service department doesn't want anything to do with it
