2018 L5P Injector Fail 5700 miles
After a couple months of flawless service I had major loss of power on the Freeway and extreme shuddering/shaking under power. Diagnosis: Multiple cylinders misfiring, failed injector and possibly injector(s). Have to order the entire set of 9 (1 for emissions crap) which takes two days to ship and estimate a two day repair just to get the injectors changed out so they can diagnose pressures and fuel flow rates. Traction Control light came on and went off twice over the roughly 20 mile trip. Check engine light didn't come on until the last mile. Had the check engine light come on earlier, I would have called for a tow.
My last Duramax was a first generation Chevy 2500. Mechanic buddy recommended I state that I was losing power on my next service visit so they would change out my injectors. I scheduled it ahead of time so they had the injectors there when I dropped it off and did the work in one day. Never thought anything of it until today. Maybe that saved me the injector flu on the first one. Can't believe these factory injectors are still such a weak link in an otherwise bulletproof engine and drive train.
Disappointing driving a little half ton loaner truck.
