What 916 owners told NHTSA about the 2012 Kia Optima Phev

Engine faílúre on June 26, 2026.Dies while moving. Engine died while turning from my side street onto busy street and traffic.I could've been struck in the rear had I not pulled out far enough in advance for the traffic to move around me. This is a second engine failure for my Kia. The engine was replaced in December 2023/ January 2024. Incident #11558201. It does not immediately restart. After some time (about an hour) it takes a long time for it to kick over then finally starts. When beginning to move forward it travels approximately 100-150 feet then dies again. A gentleman stopped to see if he could help. He thought the fuel gauge was broken and just needed gas. (Gas tank was full). Then he put the car in neutral and pushed me home with his truck. Then he helped me push it up into my driveway. I haven't gotten to the dealership (Ferguson Imports) Kia because of the cost of towing which I am responsible for if I wish to have it seen by a service specialist. It is available for inspection upon requést.

The clock spring keeps failing which is causing the air bag light to remain on; the horn to not work; various functions of the dashboard; and steering wheel heat.

The horn stops working, steering heat stop working, control functions and air bag warning. I changed the clock spring and it fixed all those issues the first time but within 6 months all those issues happened again. Is there something more wrong?

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. However one day the check engine light did come on and the OBD code P1326 came up. When I took it to the shop the check engine light disappeared and the dealership said they will not check my engine unless they see the code on their end. 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.

Sudden engine failure while driving with no warning. Vehicle began jerking, shaking, and losing power. RPMs dropped unexpectedly and the engine stalled intermittently. Multiple misfire codes were present (cylinders 1, 3, and 4), and the engine was found to have low or no compression in cylinder 1. The condition rapidly worsened to near complete engine failure. The vehicle was operating normally prior to this incident. This failure is consistent with known Kia engine defects involving internal engine damage, including rod bearing failure. This is a safety concern due to sudden loss of power while driving.

When the brake pedal is pressed on the brakes will grab. It snatches the car kinda hard. Also when you give the car gas it will hesitate and will not accelerate. Another with the gas is that you can be driving at a higher speed such as 45 to 55 or so and you press down the gas pedal like your going into passing gear and it will not accelerate it’s like it’s trying to stop. Feels like the car is gonna fall on down onto itself and it loses power.

If I was in the car any longer than 5 more minutes it possibly could’ve been catastrophic. • All I know as of right now is that 5 days ago, it was escalated and I received a case number and a case manager 3 days ago. •The car has not been inspected •not that I’ve noticed, the engine light was on a week before the accident occurred, after getting off of work and the car system said to check my breaks. I had someone take me home since my car was undrivable. And the next morning I was going to have it towed but everything was working properly. The engine light was gone.

On or around October 17th 2025 I purchased a 2019 Kia OPT un aware that the vehicle had recall problems. Once I realized the vehicle had problems I took it to get it checked out. I only had the vehicle for 2 days before the problems occurred. The Kia service center fixed the recalls all except the bearing failure. They had my car for almost 30 because we went back and forth over this issue. This reason they gave me the reason they couldn’t fix my bearing problem was because I didn’t get it checked out before I had the problem. I didn’t know the vehicle had a problem until the recall came to my attention. I just don’t understand this explanation because it just doesn’t make any sense to me. This model vehicle had a premature bearing wear long before I had this vehicle. It’s a manufactured problem and just because it wasn’t reinstated before the vehicle had the problem Kia will not stand behind the problem with this vehicle and I don’t understand that explanation. Please, please help me get this issue fixed for me please. This has really taken a toll on me and I can’t afford to just junk this vehicle so please help me. Thank you so much for trying to help me with this problem.

The failure involves the component covered under the active safety recall campaign. The affected part/system is still installed on the vehicle and is available for inspection upon request by the manufacturer, dealership, or NHTSA. Recall number : 23V6552 While driving in traffic, the vehicle suddenly began to slow down without warning, started jerking, and lost normal operation. I was forced to pull over to avoid a collision. This sudden loss of power and control placed me, my passengers, and surrounding drivers at risk of an accident. Yes. The issue was confirmed by an authorized dealership. The dealership acknowledged that the problem is directly related to the active safety recall but refused to perform the repair due to vehicle mileage exceeding 150,000 miles. The vehicle has been inspected by an authorized dealership representing the manufacturer. No inspection has been performed by police or insurance representatives at this time. No warning lights or messages appeared prior to the incident. I had not received the recall notification letter at the time I purchased the vehicle. The first occurrence happened suddenly on 12/10/2025, when the vehicle began slowing down and jerking in traffic. After I pulled over and parked, multiple warning lights and messages appeared, and the steering wheel stopped moving normally. This vehicle has an open NHTSA safety recall. Safety recalls do not expire based on mileage or ownership. The dealership acknowledged the issue is recall-related but refused to perform the repair due to mileage limits, which is inconsistent with federal safety recall requirements.

Subject: RECALL VIOLATION: Kia on the Boulevard (Philadelphia) - Refused Remedy, Charged $199, Returned Unsafe Vehicle Vehicle Information: [Year] Kia Optima Hybrid Dealership Name: Kia on the Boulevard Dealership Address: 11295 Roosevelt Blvd, Philadelphia, PA 19154 Complaint Description: 1. The Safety Incident: While operating the vehicle, I experienced a catastrophic engine failure. Thick smoke poured from the engine compartment, followed by immediate stalling. This presented a severe fire risk and safety hazard. 2. Dealer Misconduct & Illegal Charges: I towed the vehicle to Kia on the Boulevard (11295 Roosevelt Blvd, Philadelphia) for the active engine recall remedy. The dealership: * Refused to perform the recall repair free of charge. * Forced me to pay a $199 "diagnostic fee" just to look at the recall-related defect, which should be covered by the manufacturer. * Threatened me with $45/day storage fees if I did not pay the $199 and remove the vehicle immediately. 3. Current Status: Under the threat of accumulating storage fees, I was coerced into paying the $199 and towing the vehicle back to my residence. The dealership knowingly released a vehicle with a catastrophic engine failure (smoke/fire risk) back to the owner without performing the federally mandated remedy. The unsafe vehicle is now sitting at my home unrepaired. 4. Conclusion: I request an immediate investigation into Kia on the Boulevard's refusal to honor the recall and their practice of charging customers for recall-related inspections.

As a result: 1. **Internal scoring and scratches (zadir)** have been detected within the engine, consistent with **metal shavings / debris** circulating in the oil system. 2. There is **metallic residue (shavings)** found in the oil pump, which strongly suggests that worn or damaged components (likely from a manufacturing defect) were never replaced during the recall. 3. Given the extraordinarily high mileage (≈ 250,000 miles), the continued use without the required recall repairs poses **significant safety risks** and potential for further engine failure or fire. 4. I was not provided with a proper remedy when recall notices were issued — in my case, the relevant parts were not replaced in a timely fashion (or at all), despite the recall campaigns being active, leading to the deterioration of the engine. --- ## Legal and Technical Basis ### Recalls Applicable to My Vehicle - NHTSA Recall **20V750** for the 2012 Kia Optima Hybrid: This is a recall related to engine defects, including risk of engine fire.

June 26th 2025 my Kia optima 2012 EX quit on interstate 65 in Alabama was towed to dealership 10 days later was requested that I turn in maintenance records which I did. 10 days after that I was contacted and I was told that they could not read some of the records i so resubmitted. No official diagnosis was told they just informed me that the motor would be replaced. They've since removes it from the dealership to a third location. Spoke with Kia consumer affairs in a three-way call to the dealership we were hung up on three times. Trying to find out where the car had been towed to. The car is now at Monrovia towing in Alabama at $40 a day. I have takwn good care of this Kia it falls under all the criteria there were no lights no warning signs it just shut down. Not only was the dealership evasive about their decision or the decision they made me feel as if I had done something wrong when I've only had the car 3 years taken very good care of it had the oil change by fiance the records and receipts of purchase oil. Devastating. Lengthy and financially crippling. I was lead to believe early on that it was a done deal to replace the engine . They accused of fraud in regards to the records. Untrue. This has caused so much stress and anxiety in my life. I am now without transportation. I have a special needs daughter and this car was a lifeline for us. I did nothing wrong I loved this car . I'm now having to let the car go because the towing company is going to auction the car.

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)

ABS system failing

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.
