Common questions
Source: NHTSA, 49 CFR 579.5Is Infiniti ITB21-025B 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 ITB21-025B 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 ITB21-025B cover?
The manufacturer filed it against 24 model years: 2022 Infiniti Q60, 2021 Infiniti Q60, 2020 Infiniti Q60, 2019 Infiniti Q60, 2018 Infiniti Q60, 2017 Infiniti Q60 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
