2019 Infiniti QX50

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 QX50.

Body PASSENGER CARTransmission Automatic (AV-S8)

The 2019 Infiniti QX50 is classified as a passenger car and pairs an AV-S8 automatic transmission with EPA ratings of 24 mpg city, 31 mpg highway, and 27 mpg combined, while its engine requires 5.0 quarts of 5W-30 oil. Unfortunately, this model year also marks the high-water mark for owner complaints across the QX50's 2014–2025 history, accumulating 131 reports — the most of any year in the model's lifespan — with the engine being the top complaint area alongside three recalls. For researchers, that places the 2019 squarely at the peak of the model's reliability troubles, signaling a year that warrants particular scrutiny, especially around engine-related concerns.

From the factory this vehicle uses a BCI NS · 720 CCA battery, OE oil filter 1520865F1E. Note the factory front wiper blades is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 2019 Infiniti QX50 represents a dramatic spike in federal records compared to the preceding years (2014-2017), which saw a maximum of only 19 complaints and zero recalls. In stark contrast, the 2019 model year generated 131 complaints, 3 recalls, 1 investigation, and 171 TSBs, with Engine (34) and Engine & Engine Cooling (27) comprising the vast majority of the complaint areas. This target year sits at the absolute peak of the generation's complaint arc, followed by a steep decline in volume starting in 2020, though later years continued to register multiple recalls and investigations. The 2019 data also includes 3 crash complaints and 1 fire complaint, though the federal record does not specify the root causes for these or the primary engine issues. Given its position as the most problematic year in the generation's lifecycle by a massive margin, the 2019 QX50 carries substantial risk and is a poor choice for a used vehicle purchase.
