2017 Hyundai Elantra GT

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2017 Elantra GT.

Body PASSENGER CARTransmission Automatic (S6)

The 2017 Hyundai Elantra GT is a passenger car paired with a six-speed automatic transmission, delivering an EPA-estimated 27 combined mpg from its 24 city and 32 highway ratings while requiring 4.2 quarts of 5W-20 API oil for its engine. Within the model's 2013–2020 complaint history—which saw a dramatic drop from a peak of 1,293 grievances in 2013 to a low of just 49 in 2018—the 2017 model year occupies a transitional middle ground with 731 total owner complaints and four recalls. Because the engine represents the top complaint area for this specific year, researchers must weigh these moderate but notable mechanical concerns carefully when evaluating the vehicle's overall reliability profile.

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 2017 Hyundai Elantra GT stands out sharply in the federal record, with 731 complaints—more than double the 2016 total (267) and far above the 2018 figure (49). It also leads the generation in recalls (4) and technical service bulletins (181), and is the only year besides 2013 with an open investigation. While the 2013 model had even more complaints (1,293), the 2017 spike is anomalous within a generally declining trend from 2014 onward, suggesting a specific quality lapse rather than a generational weakness. The top complaint areas—engine (165) and structure (102)—along with 35 crash and 3 fire reports, point to potentially serious issues, though the data does not specify root causes. Given this outlier performance, the 2017 Elantra GT is a riskier buy than the preceding 2015–2016 or subsequent 2018–2020 model years, which show far fewer complaints and recalls.
