Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs at 105,000 mi; coolant at 105,000 mi. The big-interval services (at 105,000 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 2020 Infiniti Q50 sits near the bottom of a generation-wide improvement arc, recording only 3 complaints, zero recalls, zero investigations, and zero crash or fire complaints, down sharply from the 169 complaints and 5 recalls logged in 2014. Federal complaints trended downward across the generation from 2014 through 2019, and 2020’s minimal count continues that trajectory alongside the similarly low figures seen in 2021 and 2022. Technical service bulletins held relatively steady at 129, roughly comparable to 2019’s 121, while the absence of recalls and investigations in 2020 distinguishes it from the 3 recalls recorded in 2021. The three complaints were distributed across Power Train, Engine, and Vehicle Speed Control,Unknown Or Other,Service Brakes categories, though the data does not specify root causes. Given its placement at the low end of the complaint and recall curve, the 2020 model represents a comparatively sound year to buy in the used Q50 market.
