P2463 on GMC vehicles Soot has built up in the diesel particulate filter beyond the allowed limit

A model year is listed because the code is named in its own record — a bulletin filed against it, or an owner’s complaint about it — not because every one of these vehicles sets it. Counts are documents in NHTSA’s files, not failure rates.

Bulletins and campaigns GMC filed with NHTSA whose summary names P2463. Quote the document number at the service desk — it is a diagnosis the maker has already written down.
