2020 Genesis G80

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 G80.

Body PASSENGER CAR

The 2020 Genesis G80 is a full-size passenger car built on the brand’s rear-wheel-drive platform, and within the model’s complaint history spanning 2017 to 2026, this year falls between the peak of 94 complaints in 2018 and the low of just one in 2024. That trajectory places the 2020 model in a transitional period, where early-generation issues were still surfacing but the overall reliability trend was already moving downward. For a researcher, this year represents a useful midpoint for studying how the G80’s quality evolved as Genesis refined the platform toward its later, more trouble-free iterations.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 97,500 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
