Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 24B47 S1 a recall?
No. A manufacturer communication 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 24B47 S1 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 24B47 S1 cover?
The manufacturer filed it against 76 model years across 2 brands (Ford and Lincoln): 2024 Ford Bronco Sport, 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2022 Ford EcoSport, 2021 Ford EcoSport and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
