Mine is a 2017 GMC Yukon Denali (13000 miles currently). Had first injector (#3) go bad May 17, 2018 (11000 miles) and 2nd injector (#6) go bad June 13, 2018. Seems like there is something causing the injectors to go bad???

2015i Denali.. about a year ago I got a CEL. dealer replaced all 8 injector and fuel rail. Also, flashed module. Dealer told me 2 injectors failed but replaced all 8. mentioned there was a revision of the injectors and that is why they had to replace the fuel rail and flash the module. That's what I was told told and also was writen on the service sheet.

Just had all 8 replaced at 40,000 miles on the wife's 2016 Yukon Denali. This has to be a known issue bc after some push back, GM agreed to foot most of the bill, even though we were past warranty. As with others, we always perform regular maintenance and use premium gasoline at every fill up.
