2016 Infiniti Q50 HEV

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2016 Q50 HEV.

Body PASSENGER CAR

The 2016 Infiniti Q50 HEV is the hybrid-electric passenger-car variant of Infiniti's Q50 line, and its recorded ownership profile points to a clear concentration of powertrain concern. With 38 owner complaints on file and the engine ranking as the top complaint area, the complaint profile centers on the driveline rather than spreading evenly across systems, while the model year also carries 4 recalls. For researchers, that profile positions the 2016 Q50 HEV as a model year whose reliability history is anchored in engine-related owner reports alongside formal recall activity, with the engine serving as the logical entry point for deeper investigation.

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 2016 Infiniti Q50 HEV top in one area — the engine, 5 of 38 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. 1 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.
