Engine and engine cooling, Firerelated, Oct 9, 2025, fire
Dear NHTSA, I am submitting a formal complaint regarding my 2012 Kia Optima, which experienced an engine fire directly related to the defects identified in Kia Safety Recalls SC147, SC200, and SC201. On XXX, my vehicle’s engine failed and caught fire. This is the exact condition covered by the above recalls, which state that affected engines may seize, stall, or ignite. I have been in contact with both a Kia dealership and Kia Consumer Affairs for close to a month without any resolution. The dealership has confirmed that my car requires a complete engine replacement, but Kia has refused to address the recall issue, claiming that other unrelated recalls were not performed. When I previously contacted dealerships to schedule recall repairs, I was told that parts were not available, which prevented me from completing them. In addition to the engine failure, the fire also caused my starter to fail. I was forced to purchase a replacement starter out of pocket, which has added to my financial hardship. I believe I am owed compensation for this expense, as it was a direct result of the safety defect. This situation has caused me severe financial strain, as I relied on my vehicle for work and currently have no income due to its inoperability. Kia has not provided a timeline for repairs, towing coverage, or written confirmation that they remain obligated to remedy this federally mandated safety defect. I am requesting that NHTSA investigate Kia’s refusal to fulfill its recall obligations and intervene to ensure that my vehicle is repaired or replaced in compliance with federal recall requirements. My vehicle details are as follows: •Year/Make/Model: 2012 Kia Optima •VIN: XXXX •Recalls involved: SC147, SC200, SC201 •Incident: Engine fire, vehicle no longer drivable; starter also failed due to fire Please advise on next steps. Thank you for your time and attention to this matter. Sincerely, XXXX XXXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While in park and driving the instrument panel will show, "Check Brake" and "Hybrid System Warning! Safely Stop and Do not Drive". This is accompanied by the engine not responding to the gas pedal. The brake pedal will also loose pressure and once pushed the brakes will lock up making a grinding noise. The problem has not been able to be duplicated by the dealer. However there are multiple forms and online communities dedicated to try to resolve this issue since it's so prevalent. This issue causes a major saftey hazard as the car comes to a grinding halt and does not respond to the driver. From online sources it seems the problem is prevalent across years and models and only tied to hybrid vehicles.

On August 25th around 7:00 PM, the vehicle suddenly caught fire while parked after a short test drive. The car had just been purchased a few days prior and was taken to a mechanic for a precautionary inspection. During the test drive, the mechanic parked the vehicle in a residential driveway. After backing in, smoke was observed coming from the engine bay. When the hood was lifted, the engine area was already on fire. The fire department was called immediately and was able to extinguish the flames before the fire spread to surrounding property. The fire completely destroyed the vehicle. The vehicle had no warning lights, unusual performance issues, or prior signs of trouble, and it appeared to be in good condition prior to the incident. This fire posed a serious safety hazard and could have resulted in injury or property damage. Component or system that failed: The engine area, likely associated with the Hydraulic Electronic Control Unit (HECU) fuse/fire risk. The vehicle may or may not be available for inspection, as it is severely burned. Safety risk: The fire posed a serious hazard to the mechanic, surrounding property, and anyone nearby. Rapid ignition could have caused injury or significant property damage. Problem confirmation: The fire was observed firsthand by the mechanic. The open recall related to the HECU fuse/fire risk indicates a known defect consistent with the incident. Inspections: The fire department responded and documented the incident. The vehicle has not yet been inspected by the manufacturer or insurance representatives, but the recall status is verifiable through official records. Warning signs: There were no warning lamps, messages, or other symptoms prior to the failure. This incident appears consistent with the conditions described in the open recall for the HECU fuse/fire risk, suggesting a possible link between the recall defect and the fire.

I took my car to the KiaOfLynchburg dealership for get the recalls done and diagnostic test on my engine as it was knocking and they had it since may 06, 2025. The dealership said at first I had a code to get the engine replaced no cost. Now got a phone call on June 19, 2025 saying how my car was on fire but the fire department made it on time to put it out. So did the claim on it they denied me saying it’s due to a aftermarket but tell me it cause of oil leak. And I do not have no aftermarket hook up in the vehicle. Now they won’t take responsibility for the damage they did to my car

My 2012 Kia Optima experienced engine failure due to a dropped valve. The dealership (Kia of Des Moines) performed a borescope inspection but stopped after discovering the broken valve. This means rod bearing failure was not ruled out. Two separate service reports conflict, one citing Cylinder 2 and another citing Cylinder 3. Kia denied coverage, citing that the failure was unrelated to the settlement and outside the mileage warranty

Driving home from an oil change. All of a sudden all power was lost. Luckily a wide spot in the road was right there. Car would not start back up. Checked oil- it was good. Had car trailered to a mechanic. He took off oil filter and cut it in half- was full of metal shavings. Said needs new engine. We trailered the car back home, where it currently sits. If the wide spot in the road wasn’t there, they’re likely would have been an accident being this was right on a sharp corner.

Car simply started for me after work this past Thursday @4 pm I dove down the street and for about 5 mins and had to turn around due to me leaving something at work. When I arrived back at work I parked and cut my car off as I normally do and when I returned to start it back up it never did. I have previously been having to add 5 quarts of oil frequently at least once or twice a month for the past 7 months since last year. Was told my car had an oil consumption problem by a previous mechanical shop last year. Noticed that these cars have recalls on them and that my car and year do fit the requirements. I do owned my car with the Title in hand. It’s NOT a salvaged title. I have a service appointment on the 24th of June next Tuesday at Kia of Gastonia located in Gastonia, NC. I have to get my car towed to this establishment on Monday or the morning of my appointment. I’m asking that this situation can be properly investigated and properly and honestly handled under KIA policy.

Subject: Recall Denial Due to Salvage Title – 2012 Kia Optima (VIN:[XXX]) Dear NHTSA, I am submitting a complaint regarding Kia Motors’ refusal to perform a recall repair on my 2012 Kia Optima (VIN: [XXX]) due to the vehicle having a rebuilt title. My vehicle is equipped with the 2.4L GDI Theta II engine, which has been recalled for known safety defects including risk of engine seizure and fire. I brought my car to a local Kia dealership for the recall repair, but they refused service based solely on the vehicle having a branded (salvage) title. I then contacted Kia Consumer Affairs and was again told that the recall does not apply to salvage vehicles—even though the engine defect clearly stems from poor design and is unrelated to any prior accident or title status. I am concerned that Kia is ignoring its obligations under federal recall law and putting drivers like myself at risk. Denying a recall based solely on a salvage title—especially when the defect has nothing to do with the car’s condition—undermines public safety. I respectfully ask the NHTSA to investigate Kia’s refusal and consider whether policies like this should be permitted under federal recall enforcement standards.

I was driving home at night around 8pm. I was merging into the slow lane and my car completely lost power. A semi truck was right behind me. Luckily I was able to get over to the emergency lane safely. My car had no acceleration at all or any control of the steering. Prior to this incident there was no problem or warnings of any lights on dash or car having problems. It’s a daily driver for me to work. It’s never gave me any problems prior to this. I’ve had the routine maintenance done on along with the recommended mileage maintenance done. It’s been over a month now and my car still won’t start I haven’t had time to get it towed to a dealer ship or repair shop because I work 17 hour days. Everything I’ve researched about my make and model is starting to indicate that the engine seized up. I really hope that’s now the case because my car will be paid off in 3months. It has 165k miles on it I need help on weather the engine is part of a recall.
