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; spark plugs at 120,000 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 2019 NX300H sits near the tail end of a generation that peaked in complaints in 2015 (26) and has largely improved year-over-year. By 2019, complaints dropped to just 7—down sharply from 19 in 2018—tying with 2020 for the lowest in the dataset. The one recall in 2019 breaks a two-year recall-free streak (2017–2018), though it remains the same recall frequency as the launch year of 2015. Technical Service Bulletins fell from 213 in 2015 to 120 in 2019, indicating the manufacturer resolved many early-generation issues through cumulative service guidance. The lone open investigation carries over from prior years, with no new complaints driving it. Top complaint areas in 2019 centered on the fuel/propulsion system (2 complaints), with no crash or fire-related complaints filed. The 2019 NX300H represents a mature, well-sorted example of this generation with the lowest complaint count alongside zero crash or fire incidents, making it a favorable year to purchase within this model run.
