The problem
Kia Motor Company (Kia) is recalling certain 2011-2014 Optima, 2012-2014 Sorento and 2011-2013 Sportage vehicles. Machining errors during the engine manufacturing process may cause premature bearing wear within the engine.
The risk
Bearing wear may result in the engine seizing, increasing the risk of a crash.
The fix
Kia will notify owners, and dealers will inspect the engine assembly, and replace the engine if necessary, free of charge. The recall began June 20, 2017. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC147.

Despite documenting this catastrophic internal mechanical destruction, the authorized franchise dealer has issued a written directive instructing the driver to operate this structurally compromised vehicle on public roads for a 1,000-mile oil consumption test with explicit instructions not to add, check, or have anyone service the engine oil level. Operating an engine running dry with verified cylinder wall gouging and unstable timing chains creates an imminent, severe safety hazard for the occupants and other...

motorists, including sudden highway engine lockup, loss of power steering, or vehicle fires. The vehicle underwent Safety Recall Campaign SC147 in 2017, which carries a court-mandated Lifetime Warranty Extension on the block for core failures. The dealership is forcing an unsafe vehicle modification and dangerous roadway test to evade standard warranty coverage processing. A complete 11-invoice history proves this defect originally manifested and was logged by a technician at 96,738 miles while fully inside the standard factory coverage window.

On July 14, 2026, the vehicle's engine was replaced by an authorized dealership under an official Kia recall. On August 16, 2026, while driving on the highway, heavy smoke suddenly began emitting from the engine compartment. When attempting to slow down, the braking system suffered a total loss of power and failed completely. To stop the vehicle, it had to be steered into the highway median to intentionally scrape against it to force a stop. Immediately upon exiting the vehicle, heavy flames were observed under the engine compartment before completely engulfing the front of the car. The fire department extinguished the fire, and the vehicle is a total loss.

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.

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)

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.

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.
