New Car Assessment Program

The 2017KIAOPTIMA carries 336 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 14 fires, 11 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2017 OPTIMA is engine with 154 filings, followed by unknown or other (33) and electrical system (21). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 38 investigation files overlapping the 2017 OPTIMA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

The vehicle is consuming excessive amounts of oil. The dipstick was completely dry before 5000 miles were up. I had to add some oil to the engine to avoid engine failure. I have reported this to Jim Ellis dealership in Kennesaw GA but I was told to drive the vehicle until it knocks or the knock sensor goes.

The engine in my 2017 Kia Optima (VIN: [XXX] ) seized and locked up, a known defect associated with Kia’s Theta II 2.4L GDI engines. When I contacted Kia regarding engine replacement, I was told coverage would not apply because a required KSDS ECU update recall was not completed. During multiple phone calls with Kia Customer Care, Kia admitted that they did not have my contact information on file and added it during my call. Because Kia did not have my information, I never received any recall notification and was denied the opportunity to comply with the KSDS update. Kia has also provided conflicting information regarding whether recalls were open on my VIN while still relying on recall completion status to deny coverage. I believe Kia failed to properly notify me of a safety recall and is unfairly denying coverage for a known engine defect.

Mechanic changed the spark plugs to make it to Grand Forks Kia on 10/14/25 I was told that the Turbo needed to be replaced for $3300 before they can do an oil consumption test. There were no issues with the turbo before it was driven to Grand Forks on 10/14/25. Kia America refuses to cover the engine warranty

I own a 2017 Kia Optima with a major internal engine defect. Starting shortly after purchase, the car lost power and consumed fuel unusually quickly. Over time, the engine began burning excessive oil and now produces a loud knocking sound (bearing knock), indicating internal bearing failure. These symptoms are consistent with known Kia engine defects (bearing wear / piston ring failure). The defect is a serious safety concern: because of weak bearings and high oil consumption, the engine could stall, seize, or catch fire. The dealership has refused to repair or replace the engine. I am reporting this as a safety defect and request NHTSA investigation.
