Prep Do not reuse old bolts. Do not lubricate cylinder head bolts with engine oil. Apply a 2.00-3.00 mm bead of Hyundai sealant or equivalent RTV to the front cylinder head corners of the upper and lower head gasket. Assembly of the cylinder head must be completed within five minutes of applying the liquid gasket compound.

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.

Looking at the federal record across this generation, the 2015 Hyundai Genesis Coupe sits near the end of a dramatic downward trend in reported issues, with the early 2010 model logging 156 complaints, 5 recalls, and 81 TSBs, compared to just 7 complaints, 2 recalls, and 38 TSBs by 2016. Falling within this improving arc, the 2015 model implies a maturity over early production kinks, yet it still carries a concentrated volume of specific complaints relative to the quieter subsequent year. For the 2015 model specifically, the primary pain points center on the Electrical System (53 complaints) and Exterior Lighting (28 complaints), alongside 10 crash and 5 fire complaints, though the data does not specify the root causes of these failures. Given its favorable position on the generation's declining problem curve, the 2015 is a relatively good year to buy, provided you rigorously verify the integrity of the vehicle's electrical and lighting systems prior to purchase.
