I just leased a 2022 Silverado 1500 2.7 liter turbo. I'm trying to figure out what this engine sounds like. I have a high pitch whine when ever I'm driving. goes up and down with RPM, but it stays constant even when I am cruising. Sounds like s high pitch cricket. The sales guy said that's just the turbocharger and they all sounds like that, but I drove a different truck with the same engine and it does not have that noise. I had the dealer shop look at at and turns out there is a bulletin on it that points to the balance shift gear noise. They suggested because it's so new put a few hundred miles on it and the whine might resolve itself. Anyone else have this issue? The bulletin is PIP5887.
