It names 12 model years (2021–2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

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.

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 12 model years this bulletin names have filed 425 complaints with NHTSA since 2015. 81 of them name Engine — 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.
I moved to Reno, NV where I need to merge onto route 80 everyday. During several attempts to merge onto 80, my Genesis GV70 stopped accelerating at 42 MPH, roughly 5000 RPMs and I was almost rear ended on two occasions because of the 'stalling' of the vehicle. An 18 wheel truck almost hit me because I couldn't accelerate past 42 MPH.

I was driving down the interstate at 70 mph when my gas pedal stopped responding and the car was slowing down. Suddenly the car started beeping at me saying the engine was shut off and I needed to put it into park or neutral immediately. This happened a week prior on a 45 mph road and I was able to restart the car with no issues.

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 914G 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 914G 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 914G cover?
The manufacturer filed it against 12 model years: 2024 Genesis G80, 2023 Genesis G80, 2022 Genesis G80, 2021 Genesis G80, 2025 Genesis GV70, 2024 Genesis GV70 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: built 25 Jul 2020 – 4 Jun 2024; built 29 Mar 2021 – 4 Mar 2025; built 10 May 2023 – 13 Feb 2025 — the build date is on the certification label in the driver’s door jamb.
