2014 Infiniti QX50

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 QX50.

Body SUVTransmission Automatic (S7)

The 2014 Infiniti QX50 is a luxury SUV that pairs a seven-speed automatic transmission with an engine requiring 4.9 quarts of 5W-30 oil, achieving an EPA-estimated 20 mpg combined. This model year’s reliability is notably strong, with only two owner complaints—focused on structure and visibility/wiper issues—and no recalls, making it a far more trouble-free choice than later years like 2019, which accumulated 131 complaints.

If either diameter is less than 0.18 mm use new bolts coated with clean engine oil. Tighten all bolts to finger tight then continue on with the following procedure.

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 2014 Infiniti QX50 sits at the beginning of its generation with just 2 complaints, 0 recalls, and 0 investigations—matching the low complaint levels of 2015 (3) and 2016 (19) before the sharp escalation to 131 complaints and 3 recalls in 2019, which also triggered the model's only federal investigation. This 2019 spike represents a clear inflection point where the vehicle's complaint rate increased roughly tenfold, coinciding with the introduction of recalls and an ongoing investigation that persisted through 2024. The 2014 model's complaint areas are notably scattered (structural/visibility, fuel/electrical systems) and modest, with only 1 crash-related complaint and zero fire complaints on record. While the 103 TSBs for 2014 is high, this reflects Infiniti's active service bulletin program for new-model updates rather than defect urgency. The data shows 2014 occupies a stable pre-problem window—if the 2019 escalation reflects a later-model issue (possibly age or mileage-related), the 2014 falls before that arc and carries lower known risk. However, the ongoing investigation through 2025 with 1 active investigation still open means the full scope of any systemic issue remains unresolved. The 2014 QX50 is therefore a relatively safer purchase within this generation, though buyers should verify whether any unresolved 2019 recall campaigns have been addressed on the specific vehicle.
