2015 Hyundai Elantra GT

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

Body PASSENGER CARTransmission Automatic (S6)

As a practical passenger car, the 2015 Hyundai Elantra GT utilizes a six-speed automatic transmission and an engine running 4.2 quarts of 5W-20, 10W-30, or 5W-30 API oil to deliver an EPA-rated 24/32/27 mpg. Within the model's 2013-2020 lineage, this iteration sits well below the problematic 2013 peak of 1,293 owner complaints and above the 2018 low of 49, recording 248 total complaints with a single recall and the engine standing as the primary area of concern. This mid-generation positioning in the vehicle's reliability history means the 2015 GT provides researchers a notably more stable and dependable profile than the earlier models in the series.

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 Elantra GT sits at the bottom of a downward trend that began with the 2013 model year’s 1,293 complaints and four recalls, then fell through 2014’s 378 complaints to reach just 248 complaints, one recall, and zero federal investigations in 2015. This year marks the calmest point of the generation before complaints climbed slightly to 267 in 2016 and spiked to 731 with four recalls and one investigation in 2017, placing the 2015 model in a trough between the launch-year volatility and the later surge. Federal records show its top complaint areas as Engine (51), Unknown Or Other (28), Service Brakes, Hydraulic (23), and Steering (18), along with 27 crash-related and 8 fire-related complaints, though the data does not specify root causes for these categories. Given that 2015 carries the lowest complaint count and smallest recall footprint in the entire eight-year federal record, it represents one of the most statistically favorable years of this generation and a strong candidate for a used purchase.
