I have a 2021 GMC Sierra 1500 (not AT4) with 54K miles. About 3 weeks ago, my second cylinder failed and I had to have the entire passenger side of the engine block rebuilt. I think a spring came dislodged somehow and resulted in 2 bent pushrods. Thankfully my extended warrant covered it (after taking forever to review the claim). Has anyone else had this happen?
