Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 Q50 HEV.

Body PASSENGER CAR

The 2017 Infiniti Q50 HEV is a passenger car equipped with a two-wheel drive powertrain and requires 0W-20 viscosity engine oil for service intervals, placing it in the luxury hybrid segment that combines traditional internal combustion technology with electric assist. With 61 total owner complaints logged for this model year, engine-related issues emerged as the most frequently reported concern among the recorded problems, while four separate recall campaigns affected various vehicle systems during this production year. This complaint volume and recall activity positions the 2017 Q50 HEV as a model year that prospective buyers and researchers should examine carefully when evaluating long-term ownership costs and reliability trajectories, particularly given the concentration of powertrain-related feedback from the owner base.

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.

Owner complaints about the 2017 Infiniti Q50 HEV top in one area — the engine, 8 of 61 reports (13%), well ahead of the next concern. None of this vehicle's 4 recall campaigns target the engine, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 3 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
