2018 Infiniti Q70

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

Body PASSENGER CAR

As a passenger car, the 2018 Infiniti Q70 enters the reference record with a minimal reliability footprint — just one owner complaint on file, logged in the air bags and seat belts category, alongside a single recall. Within the model's documented 20142019 complaint history, that figure ties 2018 with the 2014 launch year for the lowest annual count, while the 2015 model year anchors the opposite end of that range with ten complaints. Set against that six-year arc, the 2018 entry stands as one of the quieter chapters in the Q70's recent record, offering a useful point of reference for how the nameplate's owner-reported issues have trended through the second half of the tracked period.

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.

The 2018 Infiniti Q70 sits near the low‑point of the model’s federal complaint and recall activity, with only one complaint and a single recall—both the fewest complaints (tied with 2014 and 2017) and the second‑fewest recalls across the 2014‑2019 span. Earlier years show a spike in complaints in 2015 (10) and a peak in Technical Service Bulletins (TSBs) that gradually fell from 150 in 2015 to 113 in 2018, indicating the manufacturer was addressing issues over time. After 2018 the pattern remains modest, with complaints rising slightly to two in 2019 and recalls increasing to two, while TSBs drop back to 89, suggesting no new major problems emerged. The sole 2018 complaint relates to “Air Bags, Seat Belts,” and there were no crash or fire complaints, implying the issue was isolated and not safety‑critical. Overall, 2018 reflects a stable year with minimal reported problems, making it a comparatively safe choice within the generation.
