NHTSA opens preliminary probe into more than 870,000 GM vehicles

[cjlewis]

For background: 2023 Denali Ultimate. Blown engine replaced @ 16K. Currently have 56K miles (total).

New engine wasn’t part of the VIN recall that was mentioned earlier in this thread.

Does anyone know what triggered that partial re-call by VINs? Seems like GM found something wrong or identified a supply chain or manufacturing issue. Not sure if this is related to the larger investigation though or a “one-off”. Would be interesting to see if engine issues by year are declining or remaining constant.... however we may never know.

So you have any specifics about what happened to the engine at 16k miles?
Spun bearing(s), which one(s), etc
