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.

What Ford owners said
Source: NHTSA complaint databaseOwners’ own words, scrubbed of anything identifying. Unverified reports filed with NHTSA — what was said, not a finding that it was true.
The repair documentation states that Diagnostic Trouble Code C1001:01 was present, wiring tests were performed, voltage was present, and the recall remedy was to replace the rearview camera
Error code (per dealership, C1001 I think but may be incorrect code) indicates a problem with the wiring that connects the camera to the center console

What C1001 means
Source: SAE J2012 / OBD-IIC1001 is a manufacturer-specific code: the second character is a 1, 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 Ford and its owners have filed about it; the code’s page across every make has the whole file.

Common questions
Source: NHTSA files and the OBD-II standardIs C1001 a known problem on Ford vehicles?
It is a documented one: NHTSA's files hold 55 manufacturer filings and 2 owner reports naming C1001 on 14 Ford model years (2016–2026). 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.
Which Ford models does C1001 appear on most?
2021 F-150 (12 documents), 2021 Mustang Mach-E (10 documents), 2022 Mustang Mach-E (8 documents).
Does C1001 on a Ford mean it is recalled?
No. Recalls are filed by campaign and matched by VIN; no recall is triggered by a scan tool. Check the VIN at nhtsa.gov/recalls, or open the model year's page here for the campaigns filed against it.
