2015 Hyundai Equus

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Equus.

Body PASSENGER CARTransmission Automatic 8-spd

The 2015 Hyundai Equus is a full-size passenger car running an engine that takes 7.55 quarts of 5W-20, 10W-30, or 5W-30 API oil, paired with an automatic 8-speed transmission and EPA ratings of 15/23/18 mpg. Across the 20112016 complaint record, the 2015 model logged only 9 owner complaints and a single recall, with seats standing out as the top complaint area. That places it near the low end of the range—just above the 2012 minimum of 8 complaints and well below the 2014 peak of 37—making this year one of the quieter entries in the Equus reliability history.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs at 105,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 2015 Hyundai Equus shows a marked drop in complaints from the 2014 peak of 37 to just 9, a level similar to the low‑complaint years of 2012 (8) and 2016 (9). Recalls remained steady at one per year from 2011 through 2015, with none reported for 2016, while investigations rose to one in both 2014 and 2015 after being absent in earlier years. Technical service bulletins declined gradually from 60 in 2011 to 54 in 2015 and further to 48 in 2016. The top complaint areas for 2015 each recorded a single incident—Seats, Exterior Lighting, Service Brakes Hydraulic, and Suspension—and there were no crash‑ or fire‑related complaints; the data does not specify any root cause for these issues. Overall, the 2015 model’s complaint and recall figures are low and consistent with the generation’s better‑performing years, suggesting it is a reasonable used‑car choice.
