2017 Kia Optima Hybrid

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

Body PASSENGER CARTransmission Automatic (AM6)

The 2017 Kia Optima Hybrid is a passenger car that pairs an automatic AM6 transmission with an engine requiring 5.1 quarts of 5W-30 oil, delivering EPA ratings of 39 mpg city, 46 highway, and 42 combined. Within the model’s complaint history spanning 2011 to 2020, this year’s 25 owner complaints—concentrated in the engine area and accompanied by two recalls—place it far below the 2019 peak of 201, signaling a relatively stable point in the nameplate’s reliability record.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 6,500 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 Kia Optima Hybrid sits at a notable inflection point in the generation's record. After a clear improvement trend from 2013 through 2016—where complaints dropped from 51 to just 4, recalls halted entirely, and TSBs fell from 145 to 96—the 2017 data shows a reversal: 25 complaints, 2 recalls (the first since 2013), and 66 TSBs on file. Investigations held steady at 3, equal to the 2015-2016 level. The top complaint areas in 2017 center on the Engine system (7 complaints), with an additional 3 complaints citing Electrical System alongside Engine concerns. Of particular note, the record shows 1 crash-related complaint and 1 fire-related complaint for this model year, though the data does not specify root causation for either. This uptick foreshadows the 2019 spike (201 complaints, 1 recall) but remains well below the generation's early-year complaint levels of 2011-2013. Concrete takeaway: The 2017 model year is a marginal buy—its recall and complaint counts represent a step back from the 2014-2016 trough, and the engine-dominant complaint pattern warrants careful pre-purchase inspection. However, it does not carry the extreme complaint volume of the 2019 model year, and its overall complaint rate is substantially lower than the 2011-2013 cohort. A thorough check for any open recalls and a detailed service history focusing on engine and electrical work would be essential before committing.
