Genesis filed this with NHTSA as a service bulletin dated Jun 20, 2023, received Jul 1, 2023, about the power train. It names 19 model years (2019–2023). 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.

What the bulletin says

Read by machine from the document NHTSA serves (7 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. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 19 model years this bulletin names have filed 500 complaints with NHTSA since 2015. 54 of them name Power Train — 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.
There is a constant wheel bearing-type noise that is distractingly audible above ~40mph, and the whine is load and annoying at ~80mph, coming from the rear of the car. There is a constant droning and harmonic pulsating noise that cannot be attenuated with the car's active noise suppression technology, either.

Any time I step on the gas to accelerate from the current speed to by pass a car (by changing lanes), the transmission down shift to third gear and does not Up-shift causing the car to reach the top speed of the 3rd gear which is slower then the speed before the shifting occured.

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 23-AT-007G 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 23-AT-007G 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. Every Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does 23-AT-007G cover?
The manufacturer filed it against 19 model years: 2023 Genesis G70, 2022 Genesis G70, 2021 Genesis G70, 2020 Genesis G70, 2019 Genesis G70, 2023 Genesis G80 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
