U2013 on Ford 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.

Bulletins and campaigns Ford filed with NHTSA whose summary names U2013. Quote the document number at the service desk — it is a diagnosis the maker has already written down.
