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.

Lincoln filings that name U3000

Bulletins and campaigns Lincoln filed with NHTSA whose summary names U3000. Quote the document number at the service desk — it is a diagnosis the maker has already written down.

What U3000 means

Source: SAE J2012 / OBD-II

U3000 is a manufacturer-specific code: the second character is a 3, which under the OBD-II standard hands the definition to whoever built the vehicle. The same code can mean one thing on a Ford and something unrelated on a Hyundai. Any site that prints a single definition for it is guessing.

A stored code names the test that failed, never the part that caused it. The record above is what Lincoln and its owners have filed about it; the code’s page across every make has the whole file.

It is a documented one: NHTSA's files hold 89 manufacturer filings and 1 owner report naming U3000 on 27 Lincoln model years (2016–2025). Whether it is a problem on one particular car is a diagnosis, not a count — but a bulletin that names the code on your model year is the place to start.

Does U3000 on a Lincoln mean it is recalled?
