Owners have filed 786 complaints
about the 2014 KIA Optima with NHTSA between 2014 and 2026.
The largest single group is the engine & cooling.
Across this model's run it ranks 5 of 20 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 76
Against the median year of the KIA Optima. 50 means typical for this
model; 100 means roughly double.
Severity — 86
16.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 42
25% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2014 KIA Optima
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543,...

During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine...

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.

Recall 2023529276,225 units in Canada
Brakes
Issue: On certain vehicles, the brake hydraulic electronic control unit (HECU) could short circuit. Safety Risk: A short circuit could create a fire risk, even while the vehicle is parked and turned off. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to replace the fuse(s) for the HECU. Kia recommends that you should park your vehicle outdoors and away from other vehicles or structures until the recall repairs have been completed.
Recall 20232752,635 units in Canada
Electrical
Issue: Kia is conducting a service campaign to inspect and upgrade the safety plug fuse. On certain Optima Hybrid (HEV) models, the safety plug fuse could blow and cause a loss of hybrid system power while driving at low speeds. Additionally, installing an incorrect aftermarket fuse could cause overheating. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Using an incorrect aftermarket fuse could create the risk of a fire. Corrective Actions: Kia will notify owners by mail and instruct you to take your vehicle to a dealership to inspect the vehicle for an aftermarket fuse and replace the 125-A safety plug with one that has a 150-A rating.
Recall 20214241,565 units in Canada

ENGINE
The component that failed on my 2014 Kia Optima was the engine. Prior to the malfunction there were no lights indicating a failure. My safety was put at risk several times as my car had completely shut down on the highway going over 55 mph in way of many vehicles causing police to shut down the highway. I took the car to several auto shops to test and there was no indication of engine failure. I’ve got my battery checked, front end alignment and oil changed on schedule. The car still malfunctioned. I had it towed to the Kia dealership in March after learning about the recall on the engine. The dealership confirmed that the engine was faulty and had been recalled. There were several other recalls on that model as well. After keeping my car for a few days and charging me a service fee, they decided not to repair the engine saying that the software was not updated prior to the engine failure and they refused to repair. I was instructed to remove my car from the facility. I called their corporate office and a representative also denied my claim saying that the mileage on my car was too great. I have not been able to get in touch with anyone that can help. The car is located in a shared parking lot amongst hundreds of tenants and close to residential areas. I don’t believe it is a safe area if there is a fire risk but Kia refuses to honor their recall. The car is available for inspection upon request if needed.

UNKNOWN OR OTHER
Issue: My 2014 Kia Optima has repeatedly experienced overheating, flashing check‑engine light, and loss of coolant. The dealership has misdiagnosed the issue multiple times and returned the vehicle to me in unsafe condition. Safety Concern: The vehicle overheats while driving, the check‑engine light flashes, and the engine loses power. This creates a serious risk of engine failure while on the road. I am concerned about potential engine damage, stalling, or fire risk due to overheating.

ENGINE
While driving down the highway, my engine completely turned off. I was able to get to a safe location. When I tried turning the car back on, it would not turn back on. I took it to Kia, and they said I was covered under warranty due to their settlement. However, due to the salvage title of the car, they will not replace the engine, even though that is what their recall settlement covers.

STEERING
The vehicle is currently experiencing failure consistent with a U.S safety call {Technical Service Bulletin) related to the steering column. A diagnostic scan has confirmed error code C1259 (angle sensor signal error) that match those referenced in the recall documentation. The vehicle was taken to a local authorized Kia dealership in Ponce, Puerto Rico, where we were informed that no recall appears in their system and that the recall “only applies to the mainland United States”. This response is concerning, as Puerto Rico is a US territory, and this defect directly impacts driver safety and vehicle control. Given that this involves steering system failure, I consider this a critical safety concern.
