Quick Navigation
Genesis G80 Generational Overview
First Generation (2017-2020)
The first-generation G80 debuted at the 2016 North American International Auto Show and went on sale in the United States as a 2017 model. This generation offered multiple engine options including a 3.3-liter V6, 3.8-liter V6, and 5.0-liter V8. A 2.0-liter turbocharged four-cylinder engine was added in 2017 for certain markets, producing 245 horsepower.
The G80 Sport trim arrived for 2018 with a twin-turbo 3.3-liter V6 producing 365 horsepower. This generation featured rear-wheel drive or all-wheel drive configurations with an eight-speed automatic transmission. Common issues included turbocharger oil leaks, ABS module fires, and transmission problems.
Second Generation (2021-Present)
The redesigned G80 launched for 2021 with a complete overhaul. This generation features two engine options: a turbocharged 2.5-liter four-cylinder producing 300 horsepower and a turbocharged 3.5-liter V6 generating 375 horsepower. The suspension was upgraded with adaptive damping for improved ride quality.
The cabin received significant improvements with better materials and technology features. Standard equipment includes adaptive cruise control and lane centering. This generation faced fuel pump failures affecting 2021-2023 models and instrument panel display issues in 2023-2024 vehicles.
Best Years for the Genesis G80
The most reliable Genesis G80 years are from the redesigned generation and select first-generation models.
2022 Genesis G80
The 2022 model is considered the most reliable G80 ever produced. Both engine options deliver strong performance with smooth transmission operation and an unobtrusive stop-start system. The suspension absorbs road imperfections effectively while maintaining controlled body motions. Standard driver assistance features include adaptive cruise control and lane centering, though some road noise remains noticeable over cracked pavement.
2021 Genesis G80
The 2021 G80 received an 86 out of 100 reliability rating from J.D. Power. This first year of the redesign replaced the V6 with a turbocharged 2.5-liter four-cylinder as the base engine. The adaptive suspension reduces body roll and handles bumps well. The cabin features well-spaced seating with quality padding, though some owners found the controls required a learning period.
2019 Genesis G80
The 2019 model earned an 81 out of 100 rating from J.D. Power for driving experience. This year came standard with a 3.8-liter V6 engine instead of the turbocharged four-cylinder found in rivals. The suspension balance provided good ride comfort without being too soft or firm. Standard safety features included automated emergency braking, lane-keeping assist, and adaptive cruise control.
Worst Years for the Genesis G80
The earliest Genesis G80 models suffered from multiple reliability issues and recalls.
2017 Genesis G80
The 2017 model experienced significant transmission problems causing high revving without gear changes and violent vibrations. These issues stemmed from faulty solenoids or worn torque converter needle bearings. Power steering failures caused the vehicle to not respond properly to steering inputs. Electrical problems affected ABS sensors, leading to short circuits and fire hazards that resulted in recalls. Forward collision-avoidance systems failed to function properly, causing accidents.
2018 Genesis G80
The 2018 G80 had four recalls issued against it. Infotainment systems provided erroneous readings and interpretations, causing driver distraction and miscalculations. Key fobs frequently malfunctioned, dying without warning and leaving owners stranded. The faulty ABS sensor issue continued, causing electrical fires from short circuits. Transmission problems included gears slipping to neutral or suddenly engaging drive while in motion. Continental Procontact TX tires showed premature wear with sidewall bubbles appearing around 20,000 miles.
Common Problems Across the Genesis G80 Lineup
Turbocharger Oil Leaks
The 3.3-liter twin-turbocharged V6 engine in 2017-2022 models developed oil leaks from the turbocharger feed pipes. Oil leaking onto hot exhaust components created fire risks, affecting 28,349 vehicles. Dealers replaced the turbocharger oil supply pipes under recall.
ABS Module Fires
The ABS module in 2017-2020 models developed electrical short circuits causing engine compartment fires while parked or driving. Owners were advised to park outside away from structures until repairs were completed. Dealers replaced the ABS module fuse under recall.
Fuel Pump Failures
The fuel pump in 2021-2023 models failed, resulting in loss of drive power and stalling while driving. Over 31,000 vehicles were affected in a 2024 recall expansion. Dealers replaced defective fuel pumps at no charge.
Transmission Issues
Early models experienced gear slipping, violent vibrations, and unintended gear changes. Faulty solenoids disrupted fluid flow through the transmission. Worn torque converter needle bearings caused strange noises during gear changes.
Electrical System Malfunctions
Electrical problems affected multiple systems including infotainment displays, key fobs, and sensors. The instrument panel display in 2023-2024 models failed due to software errors. Check engine lights illuminated due to mass airflow sensor failures, ignition system faults, and O2 sensor issues.
Steering Failures
Power steering systems in 2017 models failed to respond to inputs. The vehicle would not swerve left even when wheels were turned to a straight position. Temporary fixes required turning the wheel in the opposite direction.
Timing Chain Wear
Timing chain or belt wear affected longevity in higher-mileage vehicles. Proper maintenance intervals helped prevent premature wear. Replacement costs ranged from moderate to expensive depending on engine configuration.
EGR Valve and DPF Blockages
The 2.2-liter diesel engine experienced EGR valve and DPF filter carbon buildup from stop-start driving. Symptoms included reduced power, black smoke, and check engine lights. Cleaning or replacing these components cost between £350 and £750.
