Have a 2017 Duramax with 70,000 miles. Had an injector go out Friday. Picked up Monday afternoon. Put about 1,000 miles on it and had another one go out this afternoon (4 days later). Dealer said they recommend replacing all of them if I'm paying for it but only the ones that are bad if they are covering it under warranty. Dropping off at the dealer in the morning. Anyone else had issues with the injectors?

 

yeah...make the dealer replace them one at a time.. probably $700 each...that's their problem. I'd want to know the root cause/ type of failure. Are they full of debris and stuck open?
