We have had my suburban since April 2021 and it’s been at the dealers for 22 days. This is two malfunctions regarding the DEF pump and they are replacing it a third time. Has anyone else had issues with this? I advised them I was concerned because this is a brand new vehicle and after our warranty, granted we have lots of miles left on it, is this going to be a life long issue for our vehicle. We bought diesel to hopefully maintain and last longer. Irritated I am paying on this vehicle monthly and it’s been at the dealers this long.
