Infiniti filed this with NHTSA as a service bulletin dated Jun 10, 2023, received Jul 11, 2023, about the engine. It names 7 model years (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.

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.

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
While driving home, I experienced an extreme amount of white smoke coming from my exhaust. The smoke was so severe that I could barely see vehicles behind me. 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…
2018 Infiniti Q60 · Engine · filed with NHTSA Aug 22, 2026 · ODI 11758695
The car needed new sprockets after 105K miles. I haven't seen anyone else have this problem, so my car maybe a lemon. But just in case more people start reporting it, I just want to make sure it's on record. The dealership has no idea why they'd fail, as I have had regular, full synthetic oil changes. It's a hefty repair

Common questions
Source: NHTSA, 49 CFR 579.5Is Infiniti REV1 R22D1 Q50_Q 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 REV1 R22D1 Q50_Q 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 REV1 R22D1 Q50_Q cover?
The manufacturer filed it against 7 model years: 2019 Infiniti Q50, 2018 Infiniti Q50, 2017 Infiniti Q50, 2016 Infiniti Q50, 2019 Infiniti Q60, 2018 Infiniti Q60 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2017-2019 Q60: built 18 Aug 2015 – 29 May 2019 — the build date is on the certification label in the driver’s door jamb.
