Harley-Davidson warranty extension W146
Harley-Davidson filed this with NHTSA as a warranty extension dated Oct 31, 2025, received Nov 7, 2024, about the wheels — 2 documents under this number. It names 319 model years (2018–2025). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

Common questions
Source: NHTSA, 49 CFR 579.5Is Harley-Davidson W146 a recall?
No. A warranty extension is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the W146 repair free?
A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does W146 cover?
The manufacturer filed it against 319 model years: 2021 Harley-Davidson Duplicate PRODUCTRA1250, 2021 Harley-Davidson FLH, 2024 Harley-Davidson FLI, 2018 Harley-Davidson Flde, 2019 Harley-Davidson Flde, 2020 Harley-Davidson Flde and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
