Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; 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 2015 Infiniti Q50 sits at a pivotal point in the model's early lifecycle, representing a notable improvement over the 2014 launch year while trailing the subsequent 2016 model. Complaints dropped significantly from 169 in 2014 to 122 in 2015, recalls fell from 5 to 3, and NHTSA investigations—which stood at 2 in 2014—dropped to zero. However, the 2016 model year shows a sharper decline to just 38 complaints, suggesting the 2015 remained a transitional year for issue resolution. The top complaint categories for 2015 were Power Train (21), Steering (13), Air Bags (12), and Service Brakes (8), with 16 crash-related complaints and 2 fire-related complaints filed. Technical Service Bulletins also declined from 246 to 203, indicating decreasing dealer-level service interventions. Compared to the generation's arc—which shows steady complaint and recall declines through 2020 before stabilizing at minimal levels—the 2015 sits in the downward slope but above the much cleaner numbers of later years. This position means the 2015 benefits from early fixes to 2014's issues but hasn't yet reached the reliability plateau of 2016 and beyond; buyers should verify that Power Train and Steering complaints have been addressed on any specific vehicle under consideration.
