I have a customer using a 2017 silverado 3500ltz for hot shot hauling pulling a 40 ft gooseneck. now has 217k miles and on the 3rd set of headgaskets, 1 new head,4 exhaust valves, and an egr cooler with all the plumbing. this truck WILL NOT regen while driving. Has to be mznually regened every weekend.dealers have no clue except to charge him $300 a crack to regen when the warr. ran out.GM has no clue why this truck won't regen while driving. Has had the ecm reflashed7 times with two replacements due to internet errors that locked up the laptop and ecm.There is no aftermarket on any gaskets for this POS. Have to go to the dealer for all of it.I'm in northern ohio about to leave for southern kentucky to manually regen this truck along the road. has an extended warr.purchased at the dealer thats only good at that dealer.This truck is going to be traded in on a Ford asap!!!!!
