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 2021 Infiniti Q50 represents a notable stabilization point in the generation’s federal record, particularly when viewed against earlier years. Complaints dropped sharply from 2014–2017 peaks (169 to 61) to just 4 in 2021, mirroring the broader downward trend that began in 2018, while recalls remained modest at 3—consistent with 2018 but higher than the recall-free 2020 and 2022. The data shows no investigations for the Q50 since 2014, and Technical Service Bulletins (TSBs) continued their steady decline, reaching 111 in 2021, down from 246 in 2014. Complaints in 2021 were scattered across minor areas (e.g., wheels, air bags), with only one crash-related report and no fire incidents, suggesting isolated rather than systemic issues. This year falls in the generation’s mature phase, where early defects appear resolved and later refinements have reduced field concerns. **Given the low complaint volume, absence of investigations, and no fire risks, the 2021 Q50 emerges as a strong used purchase candidate within this generation.**
