Hello Everyone. I also have a 2017 Denali 2500 HD. I had the truck fixed under the recall for the rear defrost problem back in the summer. This past Friday morning my slider caught fire. I had 4” flames going up the plastic. Luckily I had water and was able to put the flames out after I had shut the truck off. I then pulled the fuse for the defrost and drove straight to the dealer. I have started a file with GM customer care and am waiting to see what happens. Has anyone had a fire after the defect was corrected?
