Yep. Mine does. I babied my 2023 6.2l break-in, and at just 4400 miles it STILL spun a rod bearing on cylinder three. Warranty replaced the engine. I babies the new engine even more, and just last night, I started getting slip shifts, hard shifts, then the MIL/CEL came on. So, here I am, furious, looking for answers, and about to fight for a replacement vehicle under lemon law since it meets my state's requirements.

6.2 (2023 Bad Bore Issues)

Same thing happened on my 2023 Escalade GM bought it back last month. This was my 8th GM truck Denali, Silverado, Sierra, Tahoe, Suburban had them all first time I ever did anything other than oil change or brakes before 100k miles. I was shocked since I paid north of $100k.

The dealer found metal shavings in the oil pan and GM required a new engine (vs. dealer-rebuild).

It has taken 3 months so far to have the replacement engine escalated and sent to Dealer.

I know there were a rash of 6.2L problems in 2021 to mid-2022 when the lifters were redesigned and I was hoping they were behind us...

Anyone else hearing of 6.2L engine failures in the 2023 Silverado?

The thrust bearings are flawed and clog the engine. The first symptons are that the starter goes. Then after a couple starters, the fuse box and wiring harness melt. You may replace a battery or two as well. Then you get stuck where the starter cannot turn the engine. Jumping will not help. Then the engine the engine sezzes up. THe lifters are just another symptom. They have replaced a large amount of engines and cannot state for sure that they fixed the problem. We are turning ours in as Lemon and are unsure of what to replace it with as Chevy does not provide facts
