What 1,371 owners told NHTSA about the 2013 Kia Optima

I was driving on the high way and my car completely stopped I towed it to a shop and the engine seized

NHTSA ODI 11737743

My 2013 Kia Optima was running fine at 65 mph when suddenly the engine stalled. I then coasted to the shoulder and smelled burning plastic. As soon as I opened the hood the engine started being consumed in fire, it quickly went to a very large engine fire that consumed the front half of the car. There were no other vehicles involved with this incident. Vehicle is a total loss.

The vehicle is experiencing sudden engine stalling while in motion, a known safety hazard. Despite a documented maintenance history with no issues, the dealer (Bayside Kia) is attempting to deny a Theta II Settlement claim by shifting the narrative to 'engine sludge,' which only appeared as a symptom in June 2025( Walmart oil change) alongside engine performance issues. The vehicle has active codes P0014 and P0017, which are secondary symptoms of the internal bearing wear and metallic debris contaminating the oiling system. KDS Diagnostic tests showed Cylinder 1 at 0.16mm (approaching the 0.20mm failure limit). This clearance proves the connecting rod bearings are worn and reaching the failure threshold; this mechanical wear is the root cause of the engine's inability to operate safely. The presence of metallic debris in the oil is the definitive signature of the Theta II manufacturing defect. Furthermore, the dealer acted in bad faith by attempting to charge for Airbag repairs (Codes B1346/B1481) that are covered under the 15-year Clock Spring Warranty Extension (CS1102). The dealer has dismissed my qualifying maintenance documents, claiming they are 'not official,' which is a direct violation of the Magnuson-Moss Warranty Act. A manufacturer cannot deny a warranty claim because services were performed at third-party facilities, nor can they deny a claim without proving 'exceptional neglect.' I am reporting a refusal to honor a court-ordered safety settlement and an attempt to return an unsafe, stalling vehicle to the road.There is no evidence of engine abandonment or exceptional neglect. I’m considered "in compliance" if I can show I didn't go more than 14 months without servicing or a certain mileage between oil changes.The dealer's dismissal of verified third-party receipts and bank statements is a bad-faith attempt to ignore an inherent manufacturing defect documented by a 0.16mm BCT result and metallic debris.

We were told by the mechanic that the engine was locked up after the car refused to drive faster than approximately 23 mph. We had to have the car towed from Boone, NC which was about 200 miles. The car is at our house and is available for inspection upon request. I have made repeated calls to different Kia dealers asking for a call back to assist me with direction but there will never be a returned phone call. As far as I know, there has been no inspection of the engine or vehicle.

Code : P1777 Transmission- oil pump A issue with the Valve cover gasket leaking into the engine causing a misfire. Making the car suddenly stop while driving which is very unsafe. I took the car to the dealership and they want to charge me for the repairs. I have 2 kia optima hybrid and both cars have the same issue around the same mileage. There were no warning lights during the time it was at the shop. I believe later down the line the engine will stall out and it should be fixed now while under warranty. However I received no help from the dealership unless I am willing to pay upfront. In addition to this there are electrical issues the front seats aren't moving immediately when the button is pressed. The steering wheel buttons barely work along with the radio. This is a huge problem that needs to be fixed.

I took the Kia to Hurst Dealership and Scott told me he would check it out. He called me and told me I needed the key replaced, so we paid them 230 dollars. Then he told me he found 4 recalls, fixed 3 of the 4 recalls. The last one, the engine seizing up, was still not complete. after 30 days we removed the car from that dealership because the whole time they were trying to sell us a car. Now the car doesnt even start, there is no key, there is lots of damage to the front end and underneath the engine is missing covers and who knows what else. Worst employees do the things the company itself tries to prevent, Scott is perfect for ruining reputations of the employers he (works for)

My car started shutting down while driving. After the engine started seizing the key wouldn't turn in my ignition. Took car to dealership immediately on 10, 2026. Took again in 2024 for recall and other repairs. Found out after requesting previous service incidents they failed to do recall repairs and never notified me of it, or to come back. I've requested current diagnostic report several times in writing and verbally with codes for this current service, with non compliance. My car is still at the dealership needing work and I need current diagnostic report before I pay for repairs. I am attaching a dealership diagnostic e-Report for my 2013 Kia Optima from 2024. While the report lists “No Current DTC” for several systems, it also documents multiple “Communication Fail” errors across critical modules, including Smart Key, Head Lamp, Air Conditioner, Brake, and other systems. These communication failures indicate a broader electrical or network issue within the vehicle, not simply a failed battery. The report also shows that certain diagnostic scans were not properly performed. Additionally, there are historical fault codes related to TPMS and weight classification systems, further supporting that the vehicle has experienced ongoing electrical issues. Despite these findings, the dealership attributed the vehicle failure solely to a bad battery and did not provide a current battery diagnostic test. They also failed to address an open recall related to electrical/fuse issues prior to this failure. Based on this past diagnostic report, I believe the root cause of my vehicle’s failure is an unresolved electrical defect, potentially related to the outstanding recall, rather than normal battery wear. This has resulted in my vehicle becoming inoperable and poses a serious safety concern.

1) Motor failed on interstate and car towed to automotive shop. Currently still at the shop with hope to tow to Kia to address issue. 2)My teenage daughter and her friend were placed in a dangerous and potentially life-threatening situation due to what appears to be a catostrophic vehicle failure. While driving our 2013 Kia Optima whith approximately 160,000 miles, the vehicle suddenly lost power while our daughter was traveling a major highway. The car quit responding to the gas pedal and she was forced to pull over on the side of the highway and was stranded in traffic with no safe way to move the vehicle. When she attempted to restart the car the engine light began flashing (it did not do so before hand), the car was shaking and undriveable. This was not a minor inconvenience, it was a serious safety hazard. A young driver was left sitting on the shoulder of a high-speed roadway with cars and trucks passing at highway speeds up to 80 mph. Had another driver drifted or had she not been able to reach the shoulder in time, this situation could have easily resulted in a major crash or fatality(-ies). The vehicle would not restart properly and had to be towed. Prior to this incident, there were no obvious warning sings of an imminent catastrophic failure. The mechanic's invoice of his diagnostics is attached. Vehicles should not fail in a way that suddenly leaves drivers stranded in active highway traffic with no warning. This type of failure creates an extremely dangerous situation not just for the driver but for everyone on the road. I strongly urge the NHTSA to review whether this model vehicle has known engine or safety defects that can lead to sudden engine failure or loss of power while driving. No parent should have to get a phone call that their child is stranded on the side of a major highway because their car suddenly died without warning. I am requesting this vehicle incident be documented and investigared as a potential safety defect.

I received a recall notice for my 2013 Kia Optima, VIN #: [XXX] related to engine issues and an increased risk of fire. After receiving the recall notice, my vehicle began smoking and briefly caught fire while in operation. I immediately shut the vehicle off, and the smoke and fire stopped. For safety reasons, the vehicle was towed by my insurance company to my aunt’s residence, which was the closest safe location at the time. The vehicle was unsafe to drive. No injuries occurred, and the fire department was not called because the fire stopped once the vehicle was turned off. I believe this incident is related to a known safety defect and recall involving Kia Optima engine fires. I have contacted Kia multiple times regarding this issue, and there have been delays in addressing or repairing the vehicle.

My 2013 Kia Optima SXL experienced engine knock and shutdown after completion of recall SC147 (KSDS software update). The recall did not repair the known Theta II rod bearing defect and now the engine is failing as detected by the software. Kia corporate and Kia of Merced (Merced, CA) are refusing repair, citing auction purchase and PI1803, despite the engine being covered under the Theta II engine warranty extension. The vehicle is unsafe to operate and shuts down unexpectedly.

NHTSA ODI 11709503

The engine began exhibiting symptoms consistent with the known bearing wear defect covered under the manufacturer’s safety recall, including knocking noises, loss of power, and engine malfunction. The condition worsened to the point that the vehicle became unsafe to operate due to the risk of engine seizure and sudden loss of propulsion while driving. The vehicle was inspected by a Kia dealership, which confirmed engine damage consistent with the recall defect. The engine remains available for inspection. Despite an active, unrepaired safety recall for engine bearing wear that increases the risk of engine seizure and crash, the manufacturer and dealership have refused to perform the recall remedy unless the owner first replaces the engine at personal expense. The manufacturer has stated that the recall cannot be performed due to the current condition of the engine. This refusal leaves the vehicle with an open safety recall and no manufacturer-provided remedy, creating an ongoing safety risk due to potential engine seizure and loss of power while driving.
