Well, I purchased my 2015 sierra with the 6.2L new... I hoped that I would be one of the lucky ones that beat the odds... NOPE... I experienced the dreaded lifter failure yesterday with 78k miles on it. The first look showed a bent push rod. The GMC tech said that he thought the problem was caused by the VLOM... and quoted me $8000+ to repair it which included changing out both sides lifters. Of course the dealership refuses to do the DOD delete... so I am in the process of lining up an independent shop to do the full DOD delete for $5300. Bottom line... there is no consensus on what is causing all of these lifter failures. While my knee jerk reaction is to blame a poor quality lifter, the lifter manufacturer is pointing fingers at the block manufacturer saying that there are bad dimensions of the lifter cylinder, a malfunctioning VLOM, and oil pressure being outside the required window... who knows! All I know is that I'm stuck with this thing and now I have to fix it... given the likelihood that my cam is trashed, it makes sense to me to do a full on DOD delete...
