New 2.7L Camshaft Binding Issue (PIP5865L) - What to check if you get a CEL

[Zane]

Heads up to everyone with a '24 or '25. There's a known issue with the camshaft sliding lobes binding up early. If you get a P30BF or P30C3 code, don't let the dealer tear the engine down yet. There's a specific 'Sleep Cycle' reset.

I put together a full breakdown of the fix here: https://www.gm-trucks.com/gm-2-7l-turbo-camshaft-binding-check-engine-light-fix/
