Hey guys, I just purchased a 2017 Denali HD. I’ve always owned GM trucks but this is my first diesel, I’m looking forward to learning more from this forum. I see some people have had issues with their trucks throwing codes and fortunately I haven’t had any issues so far with 1,100 miles on my truck.
most guys like to ride out their warranty until it is getting ready to expire, but in all reality if the truck does have issues it most likely is because of the emissions restrictions. So catch 22 I guess
