2019 GMC Canyon
My new 19 Canyon does the same thing. The window moves a lot. Did you talk to your service advisor and did you get it fixed? If so, how? Thanks!I have a camper shell on my truck and use the slider so that my pooch can poke her head into the cab when she's riding back there so I actually required a slider when I bought the truck.
I can move mine up and down significantly whether it latched or not and it sounds like hard surfaces hitting inside the frame. I get the feeling the gasket may have been left out of mine. I'll talk to my service advisor about it.
