What it saysTURBOCHARGER REPLACEMENT PROCEDURE This bulletin has been amended. NHTSA’s full summary ↓
Infiniti filed this with NHTSA as a service bulletin dated Nov 6, 2023, received Dec 8, 2023, about the engine. It names 14 model years (2016–2023). 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Because I was on the freeway and concerned about my safety and the safety of others, I pulled over when safe and had the vehicle towed home and then to an Infiniti dealership for…

Common questions
Source: NHTSA, 49 CFR 579.5Is Infiniti ITB22-038C 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 ITB22-038C 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 ITB22-038C cover?
The manufacturer filed it against 14 model years: 2023 Infiniti Q50, 2022 Infiniti Q50, 2021 Infiniti Q50, 2020 Infiniti Q50, 2019 Infiniti Q50, 2018 Infiniti Q50 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
