Genesis filed this with NHTSA as a warranty extension dated Mar 6, 2025, received Feb 11, 2025, about the fuel/propulsion system — 3 documents under this number: 25-FL-002G OL, 25-FL-002G DN, 25-FL-002G TSB. It names 5 model years (2019–2023). A warranty extension 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 communicationPicked out of NHTSA’s summary below, word for word. The document itself is the record, and the dealer checks the VIN.
Certain 2019-2023MY G70 (IK) vehicles are equipped with high pressure fuel pump (HPFP) assemblies that have fuel control valves (FCV) that could allow excess fuel to enter the fuel pump due to gradual wear of the FCV plunger. An air/fuel mixture that runs too “rich” may result in a reduction or loss of motive power at low speeds. The vehicle will also have Diagnostic Trouble Code (DTC) P0088. Genesis is extending warranty coverage for the HPFP under this condition to 15 years or 150,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.

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 5 model years this bulletin names have filed 139 complaints with NHTSA since 2015. 39 of them name Fuel/Propulsion 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.
The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related software update performed by the dealer, and the vehicle and all affected components are available for…

My 2020 Genesis G70 is affected by Recall 24V-528 (high-pressure fuel pump defect). About 10 months after the recall service was marked “completed,” my car began showing DTC P0088 (Fuel Rail/System Pressure Too High), which is directly tied to the recall defect.

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 Z05G a recall?
No. A warranty extension 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 Z05G repair free?
A warranty extension 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 Z05G cover?
The manufacturer filed it against 5 model years: 2023 Genesis G70, 2022 Genesis G70, 2021 Genesis G70, 2020 Genesis G70, 2019 Genesis G70. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
