It names 4 model years (2023–2024).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Certain GV60 (JW1 EV) and G90 (RS4) vehicles may exhibit an inability to perform Over the Air (OTA) software updates due to an internal logic error that prevents the updates from being completed properly. This bulletin provides instructions to perform a Data Connectivity Unit (DCU) software update to correct this condition.

Read by machine from the document NHTSA serves (9 pages), read Sep 30, 2026. A part number is shown only where it matches Genesis’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 81 complaints with NHTSA since 2015. 45 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On December 1, 2025 the car gave a series of messages on the screen indicating that there was an issue with the electrical system. I was within a mile of home and so drove home because it was operating normally at first. Driving home the car went into a limp mode and could only go very slowly 15-20 mph probably).

Sometimes after starting the car the instrument panels remain black and will not display properly for several minutes or unless the car is shutdown for a long period of time and restarted. Additionally, Genesis uses a fingerprint scan to verify who is driving the vehicle.
2023 Genesis GV60 · Electrical System · filed with NHTSA Nov 15, 2024 · ODI 11625625
on Thursday 10/24/2024 I went to use my car which was parked in my garage and although the car was unlocked none of the doors would open. The car was completely dead and I had used it just several days before. Nothing would open doors, trunk no response from the key fob.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Genesis 922G a recall?
No. A service campaign 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 922G repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 922G cover?
The manufacturer filed it against 4 model years: 2024 Genesis G90, 2023 Genesis G90, 2024 Genesis GV60, 2023 Genesis GV60. 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: 2023 – 2024 GV60 (JW1 EV): built 4 Feb 2022 – 5 Sep 2023; G90 (RS4): built 19 May 2022 – 11 Dec 2023 — the build date is on the certification label in the driver’s door jamb.
