FaultCrate・GMC Yukon 2000–2006・Noise, P0308

Candidate cause (the documents say what to do)

Engine knock on cold start (carbon on piston)

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.

In the records

No record states work done for this cause.

A cause or a result a complaint states is the owner’s view or what a dealer told them, not an established fact.

Put together by FaultCrate from public records and technical documents. The cause and the repair are for the workshop to decide with the vehicle in front of it. Counts are records, not failure rates.
