2019 Infiniti Q50

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 Q50.

Body PASSENGER CAR

The 2019 Infiniti Q50 is a passenger car built on Infiniti’s advanced platform, powered by a robust engine that requires 7.0 quarts of oil and accepts 0W‑20, 0W‑30, or 0W‑40 viscosity grades. Its engine, a standout element of the model, remains the most frequently cited complaint area in the 2019 cohort, with a total of 30 owner complaints and a single recall that year. When placed within the broader reliability timeline—spanning 2014 to 2023—the Q50’s 2019 performance sits between the 2014 peak of 169 complaints and the 2022 low of just one complaint, indicating a mid‑tier reliability standing that suggests moderate durability with room for improvement.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 45,000 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 Q50 marks the lowest point in a steep downward trajectory of federal complaints and recalls that began with the model’s 2014 introduction, which saw 169 complaints and five recalls. With only 30 complaints and a single recall—down from 42 complaints and three recalls in 2018—this model year represents the generation’s reliability nadir before reporting volumes tapered further as the fleet aged into 2020. While engine-related issues dominate the complaint profile with five filings, the specific root causes remain unspecified in the federal data, and the year recorded zero fire complaints alongside three crash-related complaints. As the 2019 model sits at the bottom of this arc with the fewest recalls and complaints of any active production year in the dataset, it presents a statistically favorable option for buyers seeking this generation.
