I have a new 2918 Denali with only 12500 miles on it the active lifters failed and cause them to have to rebuild the top have of my motor. It was in the shop for 2 months. The day I brought home they had put a water line on where it was to close to belt and ate hole in it never made it home they had to send wrecker to pick up. I finally have it home but 2 months of setting in shop depreciating is a terrible thing !!
