2015 Lexus NX300H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 NX300H.

Body SUVTransmission Automatic (AV-S6)

The 2015 Lexus NX300H is a compact luxury SUV equipped with a hybrid powertrain that achieves EPA-estimated fuel economy of 34/30/32 mpg city/highway/combined, paired with an AV-S6 automatic transmission, and requires 4.6 quarts of 0W-20 viscosity oil for service. Within the NX300H's model history spanning 2015 to 2020, the 2015 model year recorded the highest number of owner complaints at 26, with one recall issued and the top complaint category listed as "Unknown Or Other," while subsequent years demonstrated a consistent downward trend in complaints, reaching a low of 6 by 2020. This complaint trajectory suggests that while the launch year warranted closer scrutiny, the platform experienced meaningful refinement over its early lifecycle.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 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 NX300H sits at the peak of the generation's federal complaint curve with 26 reports — the highest of any model year — and a leading 213 technical service bulletins, both figures declining sharply in subsequent years to 6 complaints and roughly 120 TSBs by 2020. Recalls remain low and sporadic across the run (one each in 2015, 2016, and 2019), while investigations hold steady at one per year. The 2015 complaint profile is led by "Unknown Or Other" (5), followed by Fuel/Propulsion System (3), Fuel System, Gasoline (2), and Power Train, Engine (2), with two crash-related complaints and no fire reports; the data does not specify root causes for these categories. This first-model-year spike in activity is consistent with typical launch-year resolution patterns rather than a systemic defect trend. For a buyer, the 2015 carries the highest documented service volume of the generation, but the absolute numbers remain modest and the steep drop-off after 2015 suggests early issues were largely addressed; it is a reasonable purchase if priced to reflect its launch-year status and all recall campaigns are verified complete.
