2015 Infiniti QX70

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 QX70.

Body SUVTransmission Automatic (S7)

The 2015 Infiniti QX70 is an SUV paired with a seven-speed automatic transmission, delivering an EPA-estimated 16 city, 22 highway, and 18 combined mpg while requiring 5.125 quarts of 5W-30 API oil for its engine maintenance. Despite these routine specifications, this model year represents a notable low point in the vehicle's reliability history, recording the highest number of owner complaints across the 20142017 generation with eight total grievances primarily focused on the service brakes and accompanied by a single recall. Consequently, researchers should approach the 2015 model as the least reliable year of its era, standing in sharp contrast to the much-improved 2016 model that logged only a single complaint.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 5.125 qt of 5W-30 API engine oil, DOT 3 brake fluid. Torque the oil drain plug to 25.0 ft-lbs. The firing order is 1-2-3-4-5-6. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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 QX70 registers the highest complaint volume in this four-year federal record with 8 complaints, compared to 5 in 2014, 1 in 2016, and 7 in 2017, while its single recall matches 2014 and exceeds the zero recalls recorded for 2016 and 2017. Technical Service Bulletins declined steadily across the span from 109 in 2014 to 74 in 2017, placing the 2015 model at 100 within a downward service-trend arc despite its complaint spike. Investigations hold at zero across all four years, so the 2015 model draws no unique federal scrutiny in that regard. For 2015 specifically, federal filings cite service brakes most frequently, followed by single entries for electrical system/service brakes, air bags, and structure, alongside one fire complaint and zero crash complaints, though the data does not specify underlying causes. Because 2015 carries the greatest complaint exposure and an equal-or-greater recall count versus the cleaner 2016-2017 records, buyers prioritizing the lowest federal-record risk in this generation would fare better with a later year, making 2015 a relatively less attractive choice.
