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.

Gas smell from under the hood. When taken to the dealership it was diagnosed as the high pressure fuel line. NOTE: The high and low fuel lines have recalls that impact this vehicle make, model, and year BUT not this VIN.
The contact owns a 2013 Kia Optima. The contact stated that while driving or while the vehicle was parked, there was an abnormal fuel odor inside the vehicle. The vehicle was leaking fuel from the high-pressure pipe leading to the fuel pump. The contact associated the failure with the federal safety agency Campaign Number: 18V907000 (Fuel System, Gasoline, Engine); however, VIN was not included in the recall. The dealer was contacted; however, the vehicle was not diagnosed or repaired because the VIN was not included in recall. The manufacturer was made aware of the failure but offered no assistance. The contact was referred to the federal safety agency Hotline. The failure mileage was approximately 250,000.
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.
I own a 2013 Kia Optima and I am experiencing recurring fuel system-related symptoms. The fuel gauge fluctuates even when the vehicle has a full tank of fuel, causing an inaccurate fuel level reading. In addition, the vehicle has begun to hesitate during operation, which raises concern that there may be an underlying fuel delivery or fuel system issue. I previously experienced a similar issue years ago, and I believe the vehicle was repaired during a Kia recall or service campaign. The problem has now returned, and I am concerned that the previous repair may not have permanently corrected the issue or that there may be a related defect affecting other vehicles. The combination of an inaccurate fuel level reading and engine hesitation could create a safety concern because the driver may not know the true amount of fuel remaining and may experience unexpected loss of power while driving. I am requesting that this issue be investigated to determine whether it is related to a previous recall repair, a fuel system defect, or another safety-related condition affecting the 2013 Kia Optima.
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.
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
My 2013 Kia Optima caught fire while my [XXX] son and his friends were driving it. The car burnt up. Some truck drivers flagged my son down to let him know the car was on fire. They could have been killed if it wasn’t for the truck drivers warning him that the car was on fire while driving down the highway. 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 the federal safety agency 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.
