2018 Genesis G80 Problems: 6 Known Issues

On the 2017-2019 Genesis G80, 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 whole campaign, not 12 G80 incidents specifically.

On the 2017-2026 Genesis G80, g80 owners report the center infotainment screen freezing, ignoring inputs, or rebooting. On 2017-2019 G80s with the 9.2-inch navigation unit, owners on GenesisOwners.com describe home-screen icons that highlight but cannot be selected, SiriusXM stuck on "Acquiring Signal," the navigation map disappearing, and the radio stuck on one station. Turning the car off or hard-resetting the unit cleared it only for a while. Owners passed on the navigation provider's explanation that downloads of SiriusXM Travel Link data cause the problem, and some had their Travel Link subscription suspended as a workaround. Owners also report that replacing the head unit did not always fix it. Some 2025-2026 G80s built June 3 to November 24, 2025, and some 2026 Electrified G80s, are under safety recall 26V019. A software error in the head unit (supplied by LG Electronics) writes HD Radio and analog radio data to the same memory location. That can make the head unit reboot, and the instrument cluster and center screen go blank for about 5-10 seconds with no warning. A blank cluster hides the speedometer, fuel gauge and warnings. Hyundai counted 237 U.S. reports before filing the recall.

On the 2018 Genesis G80, 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.

On the 2018 Genesis G80, 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.

On the 2017-2020 Genesis G80, 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.

On the 2018-2020 Genesis G80, 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.
