2018 Infiniti Q70 HEV

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Q70 HEV.

Body PASSENGER CAR

The 2018 Infiniti Q70 HEV is recorded as a passenger car, and with both engine-oil recommendation and viscosity listed as not specified, its technical profile in this data set offers no fluid specifications but instead points to a reliability history defined by minimal documented issues. The model accumulated just one owner complaint and one recall, with the sole reported concern area logged as Air Bags,Seat Belts. That scarcity of entries places this model year at the low-volume end of the Q70 HEV’s reliability history, meaning researchers are working from a narrow but precise band of owner-reported data.

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 2018 Infiniti Q70 HEV dominate in one area — the air bags,seat belts, 1 of 1 reports (100%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the air bags,seat belts, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the air bags,seat belts 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.
