P1101 on Chevrolet vehicles

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.

Owners’ own words, scrubbed of anything identifying. Unverified reports filed with NHTSA — what was said, not a finding that it was true.

Bulletins and campaigns Chevrolet filed with NHTSA whose summary names P1101. Quote the document number at the service desk — it is a diagnosis the maker has already written down.
