bent push rod in cylinder 3 in a 2021 6.2 GMC with 7100 miles, parts are hard to find. Finally off back order and on their way to the dealer. GMC says it's a permeant fix. Better not be a band aid fix. Didn't get a loaner even though it's in writing. Said the faulty parts are all coming from one place. You'd think they would have this taken care of if it's happened in the past years....What a JOKE
