Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 48,000 mi; coolant every 24,000 mi. The big-interval services (every 24,000 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.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2023 Genesis G80 shows a complaint level of 8, representing a slight uptick from the 2022 low of 6 but still dramatically lower than the 2017-2018 peak of 63-94 complaints. This places 2023 near the bottom of a clear downward trend in complaints that began after 2019, while the recall count remained steady at 4 (matching 2021-2022), indicating Genesis continued addressing engineering issues even as customer reports declined. Notably, there were zero NHTSA investigations for 2023, consistent with the pattern since 2019, and TSBs dropped slightly to 55 from 56—suggesting the vehicle's technical documentation needs were stabilizing. The top complaint area was fuel system issues (3 instances), with one crash-related complaint and no fire reports. Compared to the 2024 data (1 complaint, 2 recalls), the 2023 sits at a transitional point where complaint volumes remain low but manufacturers were still actively issuing recalls and service bulletins. The 2023 model year appears to be a good value within this generation's reliability arc—it benefits from the quality improvements that drove complaints down from earlier years while retaining the more comprehensive recall coverage from 2021-2022, without the newer model's potentially incomplete data.
