Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2012 Genesis.
Body PASSENGER CAR
The 2012 Hyundai Genesis is a passenger car that takes 5.5 quarts of 5W-20 or 5W-30 API oil. It logged 269 owner complaints with the engine as the top complaint area and five recalls. Across the 2008–2018 model run, the 2012 sits well below the peak of 305 complaints seen in 2015 but far above the single complaint recorded for the 2008 debut year, placing it in the middle of the model's reliability spectrum.

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.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Across this generation, federal records show a fluctuating trend of complaints and technical service bulletins, with a notable surge in activity between 2009 and 2013. The 2012 model year sits at a local peak in this arc, recording 269 complaints and 112 TSBs, which is a sharp increase over the 144 complaints and 81 TSBs seen in 2011. Top complaint areas for the 2012 model include the engine (36) and hydraulic service brakes (33), though the data does not specify the root causes for these issues. Safety records for 2012 include 5 recalls, 1 investigation, 8 crash complaints, and 1 fire complaint. This volume of reports is higher than any year between 2009 and 2013 and is only exceeded by the 2015 model. Because this year represents a high point for complaints and TSBs, it is not a recommended year to buy.
