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.

The engine on my 2013 Kia Optima (VIN [XXX] ) failed catastrophically less than one mile after purchase. This vehicle is subject to Kia Safety Recall SC147, which addresses a manufacturing defect involving engine bearing wear caused by factory machining debris and identifies engine replacement as the remedy when failure occurs. A Kia dealership inspected the vehicle and confirmed the failure was denied under warranty. I then requested that the dealership pursue recall compliance under Safety Recall SC147. After consultation with Kia Techline and a Kia service representative, the dealership declined to submit or pursue recall compliance for this engine failure. I am submitting this complaint for recall non-compliance and request that this matter be reviewed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The check engine warning light illuminated once the knock started in the engine. The vehicle was not repaired. The vehicle was driven to the dealer. The contact stated that there was an open recall associated with the VIN; however, the dealer declined to repair the vehicle because the engine was knocking. The manufacturer was made aware of the failure. The failure mileage was approximately 88,000.
Power train, Engine, Fuel/propulsion system, Jan 5, 2026
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.

Engine Seized After Kia Recall Repairs – Safety Defect Recurrence I own a Kia vehicle (VIN: [XXX] ) with a rebuilt title. Kia performed engine recall work on my vehicle at Fowler Kia in Longmont, Colorado. The service advisor stated the recall was to “protect the engine from seizing.” After driving around 18,000 miles since the recall service, the engine seized suddenly while operating. Kia Customer Affairs has denied warranty coverage because of the salvage title, but this does not change the fact that the defect is safety-related and persisted after recall work. This creates a serious safety concern because: The engine failure happened without warning, Kia performed the recall on this exact safety defect, And now they are denying any further responsibility. I request that NHTSA investigate Kia’s handling of safety recalls on vehicles with rebuilt titles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Sunday, September 21st, 2025, my 2013 Kia Optima EX suffered sudden catastrophic engine failure while driving on the highway. The check engine light was flashing, the car misfired badly, lost complete power, and became unsafe to operate. The vehicle was then towed to Wagner Kia of Shrewsbury, MA. On Monday, September 22nd, Kia diagnosed the engine with holes in the intake valves (Cylinder 3) and multiple misfire codes (P2191, P0272, P0301, P0304, P0172, P0303). The dealership documented that major engine repairs would be required, including two intake valves, two exhaust valves, valve cover gaskets, hraf bolts, two ignition coils, and a valve job. This sudden engine failure created an immediate safety risk of stalling or losing power while in motion, which could have led to an accident. Despite Kia’s history of Theta II engine recalls and settlements, my VIN is not included, leaving this major engine defect unaddressed. I am requesting that NHTSA investigate and consider expanding Kia’s existing engine recalls to cover this engine failure, as it represents a serious safety issue consistent with Kia’s documented engine problems.

Engine blew up. Was burning oil since I got it, only had it for 6k miles. It started knocking at some point so I stopped driving it and was gonna take it to the dealership n get it repaired since tbat shouldve been fixed by SC147 but the engine blew on the way to the dealership. It happened on a very main road, and I couldnt get my car fully out of the way of traffic due to it making an abrupt stop shortly after the engine blew up. We had to call a towtruck and a police officer due to how busy the road was, and there was a good fresh 5 quarts of oil spilt all over the ground, on a main road. The dealership is saying they're trying to deny my warranty since the engine passed their test & I do my own oil changes but I have perfect documentation of each oil change, including date, miles, oil weight & volume, even the amount the car burnt in that period. I called kia consumer affairs, they said I dont even have a warranty because I didnt get the knock detection sensor upgrade done, and they wont do SC147 past engine failure. The dealership said themselves my engine is shot.

After picking up my 2013 Kia Optima from a Kia dealership for an engine recall repair, I was told that no issues were found with the vehicle. The following morning, while driving on the freeway, the vehicle suddenly stalled without warning and lost power in the middle of traffic. This created a dangerous situation, as the driver was left stranded in an active lane with vehicles traveling at high speeds. Prior to dropping off the car, multiple independent mechanics and a body shop had advised that the vehicle was unsafe to drive due to engine concerns. The dealer stated they could not reproduce the issue and cleared the car for use. However, within hours of getting the car back, the stall occurred. The vehicle is currently available for inspection. The problem has not yet been confirmed by the dealer, but the symptoms are consistent with known Kia engine failures related to connecting-rod bearing wear. Before the stall, the check engine light had intermittently illuminated, but the dealer reported “no issues found.” This failure put the driver and surrounding motorists at serious risk of a collision and highlights that the recall remedy may not have addressed the underlying safety defect.

Hello, I have been a KIA owner for a very long time. I am dissatisfied with the corporation regarding my current experience. My vehicle qualified for the engine recall. Over several months I have been bringing my car into KIA Valley regarding concerns of the performance of my car which is connected with the recall. Every time I have brought in my car , the code has not popped up yet. I followed up with a phone call to KIA customer service. Over the phone I was told that the code needs to be popped up. In order for that to happen, that would require my car to seize or the engine catch on fire. The FACT THAT THIS COMPANY IS WILLING TO PUT LIVES AT RISK, is alarming. A few weeks ago at 10:00PM at night my car seized on the on ramp of freeway. Took car to dealer. I was informed the code did not pop up and the KIA dealer filled my car with more oil.A week later, my engine completely seized and oil was everywhere. I WAS IN FEAR OF MY ENGINE CATCHING ON FIRE. I got out of my car and called a tow truck. I was informed by the service dealership that the code popped up. Meaning I now qualify for a new engine. The following day I received a phone call that CORPORATE IS KICKING IT BACK AND DEMANDING AN ABUNDANCE of receipts. Receipts dating back even several years, to try to prove its neglect on my end, for the company to avoid cost. When clearly this is due to the recall per the service dealer. I recently went to the dealer to bring several receipts showing the care for my KIA. IT IS STILL NOT GOOD ENOUGH FOR CORPORATE. Receipts even included documentation from other mechanic businesses that did not want to work on my car because their finding with my engine appeared to be linked to the recall. They told me it was unsafe to drive and take it to the dealer. Over the past 8 months because KIA CORPORATE has made it difficult. I am seeking help.
