The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Candidate cause (the documents say what to do)

Engine knock on cold start (carbon on piston)

Applies to: 4.8L, 5.3L, 6.0L only

The noise is usually more noticeable on initial start-up below 10°C (50°F) and may be more pronounced on the first cold start after a long trip.

The noise may be caused by an interaction between carbon formed on the piston, the piston motion and the cylinder wall.

What to do

No technical document states a check or a repair.

Caution: GM Powertrain Engineering confirmed the noise is not detrimental to the performance, reliability or durability of the engine.
