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

Kind of thinking the 2017 engine with over 100k suffering from a failed rod bearing could be due to Low Speed Pre Ignition (LSPI)?? LSPI in conjunction with 0W20 oil probably is not an ideal situation. Adding a catch can to also capture and remove additional oil vapors that end up being added back to the combustion airflow that could also help reduce LSPI.

Things to consider

I got a brand new Tahoe in January, 2024, and in November I had a catastrophic engine event with the 5.3L. I got stalled with a child in the middle of a busy intersection and it took a month for them to get my engine replaced. The service tech believes the fuel management system broke down starving the engine of fuel and causing a piston to break off.

I have owned vehicles for nearly 30 years and never had anything close to this happening. Is this recall for the 5.3 and 6.2?

FWIW it's not a recall. Might never be.
