What it saysThis article supersedes TSB 21-2175 to update the TSB Service Procedure. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated May 27, 2024, received Jun 6, 2024. It names 79 model years across Ford and Lincoln (2016–2019). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 24-2165 a recall?
No. A service bulletin 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, or on its page here.
Is the TSB 24-2165 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB 24-2165 cover?
The manufacturer filed it against 79 model years across 2 brands (Ford and Lincoln): 2018 Ford C-MAX, 2017 Ford C-MAX, 2016 Ford C-MAX, 2019 Ford EcoSport, 2018 Ford EcoSport, 2018 Ford Edge and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
