Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 42,000 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.

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 2021 Genesis G90 shows a modest complaint count of 5, mirroring the low level seen in 2020 and slightly above the 2 complaints of 2022, while recalls remain minimal at one, a steady drop from the three recalls in 2017 and the four in 2018. This places 2021 near the bottom of the recall trend for the generation, suggesting improved reliability compared to earlier years. The four top complaint areas—Electrical System, Forward Collision Avoidance, Steering, and Engine/Fuel—are single incidents each, and the data does not specify root causes. Crash and fire complaints are both low (1 and 0 respectively), reinforcing the overall safety record. Given the continued downward trajectory in both complaints and recalls, 2021 is a favorable year to purchase a used G90.
