Recall 26V229 / 033G covers certain 2021–2025 G80 vehicles, with 7,195 G80 included in the initial 94,760-vehicle Genesis filing. Insufficient torque-stabilizer concentration during assembly can reduce fastener retention force over time at the crossover pipe connecting the engine's two fuel rails. A loose connection can leak fuel and increase fire risk; fuel odor is the stated possible warning. This is distinct from 21V208's pump-to-rail tube on a limited group of 2.5T four-cylinder vehicles. Do not infer overlapping engine eligibility from those separate campaigns.

Common Symptoms

  • Fuel smell or odor

How to Fix

Ask Genesis to confirm VIN eligibility, current remedy availability and repair history. The filed remedy inspects the crossover fuel pipe: replace and tighten it if a leak is found; otherwise retighten to specification. The eligible recall remedy is free. If raw-fuel odor or suspected leakage occurs, stop using the vehicle and contact the retailer for prompt assessment and safe transport rather than waiting for a mailed notice. If fire is suspected, stop safely, switch off, get everyone out and at least 100 feet away from the vehicle and traffic, and call 911. Do not open the hood or attempt to fight the fire.

If you own a 2022 or 2023 Genesis G80, it may be covered by a safety recall over a fuel pump that can fail. The failure mode NHTSA describes is a loss of drive power — the sedan can stop delivering power to move the car. Because that can happen without warning while the G80 is being driven, NHTSA rates the consequence as an increased risk of a crash. Hyundai Motor America filed the campaign as internal recall 022G, and it is an expansion of the earlier recall 23V-630 — additional vehicles were brought in after the original campaign. In total, 31,440 vehicles are covered across every Genesis model named in the campaign; that number spans the entire campaign and says nothing about how many G80s are involved.

Common Symptoms

  • Loss of drive power

How to Fix

Dealers inspect the vehicle and replace the fuel pump assembly free of charge — there is no cost to the owner and no mileage or time limit on a safety recall remedy. Hyundai mailed owner notification letters on June 7, 2024. To check your own car rather than rely on the mail, enter the G80's 17-digit VIN at nhtsa.gov/recalls, which will show whether it is included and whether the fuel pump has already been replaced. For questions or to find a Genesis dealer, call Hyundai customer service at 1-855-371-9460 and cite recall 022G.

Recall 21V208 / 008G covers 31 US-market 2021 G80 vehicles with 2.5-litre turbo engines built January 28–February 5, 2021, within a 147-vehicle G80/GV80 campaign. A damaged manufacturing screw guide produced fuel-tube ends that may not seal correctly between the high-pressure pump and rail. Leakage can increase engine-compartment fire risk in the presence of ignition. Listed possible warnings include fuel odor, smoke, burning or melting odor, and MIL or battery-light illumination; a warning alone does not identify this tube.

Common Symptoms

  • Fuel odor
  • Smoke or burning/melting odor
  • MIL or battery warning light

How to Fix

Have Genesis verify the VIN and perform the free replacement of the affected high-pressure fuel tube. Do not wait for a warning or assume every 2021 2.5T is included. If fuel odor or suspected leakage develops, stop using the vehicle and contact service for prompt assessment and safe transport rather than treating it as a normal cold-start characteristic. If fire is suspected, stop safely, switch off, get everyone out and at least 100 feet away from the vehicle and traffic, and call 911. Do not open the hood or attempt to fight the fire.

Recall 24V107 / 018G includes certain 2017–2019 G80 vehicles built March 17, 2016–January 4, 2019. Water can contaminate the starter solenoid in abnormally wet conditions, such as a flooded road, and cause an electrical short over time. An engine-compartment fire can occur while parked or driving. The July 2024 retailer notice reports 12 US thermal incidents across the campaign as of its stated reporting context, not 12 G80 incidents specifically.

Common Symptoms

  • Difficulty or inability to start the engine may require immediate retailer assistance
  • Engine-compartment fire while parked or driving

How to Fix

Arrange the free 018G remedy through Genesis: install the specified starter relay kit and replace the engine-room junction-box upper cover and label. Park unrepaired affected vehicles outdoors away from structures. If performance concerns occur, including difficulty or inability to start, Genesis directs owners not to drive further before the remedy and to contact the retailer for assistance. The standard campaign is not automatic starter replacement; separately diagnosed damage may require additional work. If fire is suspected, stop safely, switch off, get everyone out and at least 100 feet away from the vehicle and traffic, and call 911. Do not open the hood or attempt to fight the fire.

The Integrated Charging Control Unit in the Electrified G80 charges the 12-volt auxiliary battery and powers low-voltage accessory equipment. Certain load conditions can make its internal MOSFET fail, potentially opening the ICCU fuse so the 12V battery no longer charges. Genesis attributes the fault to overvoltage at the start and end of the battery charging cycle and to thermal loading during charging or driving. On detection the car shows a series of warnings and enters a fail-safe mode that gradually reduces motive power as the 12V battery discharges; driven until the battery is depleted, it loses all motive power. Genesis first recalled 2023-2024 Electrified G80 cars in March 2024 (24V204 / 021G); in November 2024 it issued 24V868 (025G), which replaces 24V204 for 1,995 model year 2023-2024 Electrified G80s produced February 23, 2022 to August 22, 2024 and adds revised ICCU software with an LDC output-voltage soft start and improved radiator fan and water pump operation.

Common Symptoms

  • Dashboard warning lamps and an audible chime
  • Warning messages on the vehicle information display
  • Dead or repeatedly discharged 12V battery
  • Gradual reduction in motive power or speed, then complete loss of drive power if driven until the 12V battery is depleted

How to Fix

Free recall remedy under NHTSA 24V868 (which replaces 24V204): the dealer updates the ICCU software and inspects and, where necessary, replaces the ICCU and its fuse. If your car was repaired under 24V204, it still needs the 24V868 remedy. Confirm the VIN is clear before buying a used Electrified G80. If EV-system warnings or loss of drive power occur, stop in a safe place and obtain assistance. The recall describes a series of warnings and progressive power reduction as the 12V battery discharges; continuing until it is depleted can result in complete loss of motive power.

On affected 2018–2020 G80 vehicles with the 3.3-litre turbocharged V6, prolonged engine-compartment heat can crack the left turbocharger oil-supply pipe. Oil reaching the exhaust manifold increases fire risk. The filing lists possible white smoke, a burning smell and oil leaking onto the ground as possible warnings. Recall 24V191 / 019G expands and replaces 19V538; vehicles repaired under that older action still require the new remedy.

Common Symptoms

  • White smoke
  • Burning smell
  • Oil leaking onto ground surfaces
  • Engine-compartment fire

How to Fix

Contact Genesis promptly to confirm eligibility and replace the left turbocharger oil-supply pipe under the free 24V191 campaign. Earlier 19V538 completion is not sufficient. If smoke or a burning smell occurs, seek immediate assistance rather than waiting for a routine appointment. Any customer-paid work requires a vehicle-specific diagnosis and estimate. If fire is suspected, stop safely, switch off, get everyone out and at least 100 feet away from the vehicle and traffic, and call 911. Do not open the hood or attempt to fight the fire.

Certain 2018 G80 (DH) sedans produced January 18, 2017 through June 5, 2018 have a front passenger Occupant Classification System control module that may have been programmed incorrectly. The system can detect an adult when the seat is empty, or fail to switch the front passenger airbag off when an infant or child is present - meaning the airbag can deploy in a crash when it should have been suppressed. The warning Hyundai lists is the "Passenger Air Bag OFF" indicator turning off, including when the seat is empty or a child or child seat is in it.

Common Symptoms

  • Passenger Air Bag OFF indicator may be off when the front passenger seat is empty or occupied by a child or child restraint

How to Fix

Free recall remedy under NHTSA 18V496 (Genesis campaign 002G): the dealer reprograms the OCS module. Do not rely on the passenger-airbag-off lamp on an unremedied 2018 G80; keep children in the rear seat until the VIN is confirmed clear. If a part is found to need replacement during the recall, the bulletin directs a separate warranty or goodwill claim.

A small batch of 2018 G80 sedans left the plant with the front windshield and rear window bonded using incorrect primer, which may lose some of its glass bonding strength over time. Genesis warned that the glass could become detached while driving. The campaign is narrow: only 2018 G80s produced between February 14 and February 21, 2018 are covered (the same NHTSA campaign also includes certain 2018 G90s; 37 vehicles in total). Ask Genesis to confirm VIN eligibility and whether the glass replacement was completed; a build date alone does not establish repair status.

Common Symptoms

  • Front or rear glass could become detached while driving (no advance warning sign is listed in the recall)

How to Fix

Check VIN eligibility and repair history for recall 18V305 (Genesis 001G) with Genesis. The recall remedy replaces both the front windshield and rear glass at no charge. The NHTSA VIN tool is a useful open-recall check, but it does not show already completed recalls and cannot by itself establish the condition or repair history of the glass. Have loose, moving or leaking glass assessed promptly.

Recall 21V160 covers certain US-market 2017–2020 G80 vehicles and predecessor 2015–2016 Hyundai Genesis vehicles, with 94,646 vehicles combined. The ABS hydraulic controller may develop an internal electrical short and overcurrent, creating engine-compartment fire risk while parked or driving. The March 2021 filing states the root cause was still under investigation and lists smoke, burning or melting odor, and MIL or battery-light illumination as possible warnings. G70 is covered by a separate campaign.

Common Symptoms

  • Smoke from the engine compartment
  • Burning or melting odor
  • MIL or battery warning light

How to Fix

Have Genesis verify VIN eligibility and campaign completion. The free 21V160 remedy replaces the ABS-module fuse with a lower-amperage fuse to limit current. Park affected unrepaired vehicles outside, away from buildings and flammable materials, as instructed by Genesis/NHTSA. If other damage or faults are present, have them diagnosed; the recall filing does not prescribe automatic module replacement for every warning. If fire is suspected, stop safely, switch off, get everyone out and at least 100 feet away from the vehicle and traffic, and call 911. Do not open the hood or attempt to fight the fire.

Genesis TSB 21-AT-010HG (June 2021) addresses slipping, shift flare or harsh 2–3, 3–4 or 4–5 upshifts on 2017 G80 (DH) 3.8L and 5.0L cars produced 3/17/2016 to 1/11/2017 by replacing the 35R and 4&OD shift solenoids. It is not a universal solenoid remedy for later G80 generations.

This issue also affects: Hyundai Entourage, Kia Amanti, Hyundai Genesis Coupe

Common Symptoms

  • Hard or harsh 2-3, 3-4 or 4-5 upshift
  • Engine revs flare between gears on those upshifts
  • Slipping during the 2-3, 3-4 or 4-5 upshift

How to Fix

Confirm the 2017 DH engine and production date (driver door pillar tag) and reproduce the specified shifts with warm ATF. Follow bulletin fault-code and wiring checks before the solenoid procedure. Metal particles or burnt-smelling ATF call for the bulletin's transmission-replacement prior-authorization branch, not simply a drain-and-fill followed by solenoids. Normal warranty eligibility applies.

Certain second-generation RG3 G80 sedans (2021 model year onward) may have a noise condition from the rear differential. Genesis TSB 23-DS-004G (August 2023), which also covers GV70 and GV80, has technicians check the G80 for a whine while coasting off throttle between about 50 and 25 mph. Depending on what the inspection finds, the bulletin repair tightens the rear differential lock nut or replaces the differential.

Common Symptoms

  • Whine from the rear differential while coasting off throttle, roughly 50 down to 25 mph
  • Noise may occur in only part of that speed range

How to Fix

Ask the dealer to verify current bulletin applicability and diagnose the rear-differential noise. For G80 RG3, the cited bulletin checks whine while coasting off throttle from 50 to 25 mph. Its repair tightens the existing lock nut under tightly controlled conditions; it does not replace that nut. Loosening it, exceeding the allowed tightening range, or persistent specified noise can require differential replacement. This is a trained-technician procedure; confirm normal warranty eligibility separately.
