So, my Silverado is a 2022 6.2 with about 21,000 miles and has been at the dealership for 1 month now.
The motor started making all kinds of noise that I thought was the lifter fail, but after watching too many
videos on youtube I suspect it has spun a rod bearing[s]. Dealer tells me it will be covered but is still waiting
on GM to authorize repair or complete replacement of the engine. Pretty bummed out and don't feel optimistic
that I will get the truck back anytime soon. At least they gave me a brand new truck as a loaner lol!
