Body SUVTransmission Automatic (S7)

The 2015 Infiniti QX50 is an SUV equipped with an Automatic (S7) transmission that delivers EPA estimated fuel economy of 17/25/20 mpg while requiring 5.125 qt of 5W-30 API engine oil. Within the model's complaint history covering 2014-2025, this specific year recorded only 3 total owner complaints and 0 recalls, standing in sharp contrast to the 131 complaints logged during the peak in 2019. Although the Power Train is listed as the top complaint area, the minimal volume of reported issues positions the 2015 QX50 as a low-complaint entry within the vehicle's broader reliability timeline.

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 QX50 sits at the favorable early end of its federal record, with just 3 complaints, zero recalls, and zero investigations — virtually identical to the 2-complaint baseline of 2014 and a fraction of the 19 complaints logged for 2016. The 100 technical service bulletins attached to 2015 are consistent with the 103 issued for 2014, suggesting steady manufacturer service activity rather than a defect-driven campaign, and the three complaints are thinly distributed across Power Train, Exterior Lighting, and Engine (one each), with no crash or fire reports. Looking at the longer arc, the model years that follow show a meaningful escalation — 2016 jumps to 19 complaints and the 2019 model year spikes to 131 complaints alongside 3 recalls and an active investigation — meaning 2015 predates the generation's clearly worse stretch, though the data does not specify what triggered the 2019 surge. The target year is also free of the recall and investigation activity that appears in every year from 2019 onward. For a used-buyer, 2015 is arguably the cleanest year in the dataset, combining the lowest complaint volume with no recall exposure, making it a defensible choice over the higher-mileage later model years.
