2012 Kia Optima Engine

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 contact owns a 2012 Kia Optima. The contact stated that the engine was knocking at startup. The contact referenced NHTSA Campaign Number: 17V224000 (ENGINE AND ENGINE COOLING); and the VIN was included in the recall; however, the manufacturer declined to honor the recall because the original owner of the vehicle had failed to respond to the recall notification. The local dealer was contacted. The contact stated that the manufacturer had declined to honor the recall due to the previous owner not having the vehicle repaired. The manufacturer was made aware of the issue. The failure mileage was 189,369.

The car seized operating, shut down with zero warnings. It has been a reliable car and maintained. We towed to a mechanic who said it was engine failure. Thankfully we had just exited off highway and on a side street when it became inoperable or it would have been detrimental.

Bearing wear resulted in the engine seizing.

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.

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.

The contact owned a 2012 Kia Optima. The contact stated that while driving 60 MPH, the vehicle jerked, with an abnormal hissing sound coming from the front of the vehicle. The contact stated that there was smoke coming from the rear of the vehicle and entering the cabin of the vehicle through the A/C vents. The contact stated that several warning lights were illuminated. The contact pulled over to the side of the road and the vehicle was towed to an independent mechanic. The contact was informed that there was a hole in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The contact notified the insurance company; however, no claim was filed. The failure mileage was approximately 160,000.

While driving 2012 Kia Optima GDI home from work, the power suddenly stopped without warning with the engine, oil, and battery lights flashing on all at once. I was unable to accelerate whatsoever, so with the momentum of the vehicle I parked safely in a parking lot. There I discovered the car would not start and would give a loud clunking sound. A mobile mechanic confirmed that the engine was seized, and I had it towed to the nearest KIA service center. They were able to also confirm it was an engine seize, but insisted KIA would not replace the engine despite a recall notice of the motor of this vehicles make and model in 2017 (SC147).

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. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

See attached document for complaint.

The contact owns a 2012 Kia Optima. The contact stated that while his daughter was driving on the highway at 65 MPH, the vehicle lost automotive power, with the check engine warning light illuminated. The vehicle was towed to an independent mechanic where the vehicle was diagnosed, and the contact was informed that the internal bearings had failed, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 200,000.

On the evening of December 5, 2024 my 2012 KIA OPTIMA's engine completely seized out of no where while traveling on a very busy road where the speed limit is 50mph putting my life and other drivers that share the roads life in danger. Thank god I was able to succesfully merge over into a safe place as the car came to a hault. Previous to this incident the car was running perfectly fine with no dash lights on what so ever. Once I was in a safe place I called KIA headquarters immediatly, I was told that I have to pay to have the vehicle towed to the nearest dealership and that I would be reinbursed depending on the issue of the vehicle after being diagnosed. The very next morning I called KIA corporate to open a case for the vehicle, in which i was told that my specific year, make and models engine was under a lifetime warranty. I then recieved a call from the dealership Decmember 6, 2024 and i was told my optima would be diagnosed and if the issue is due to the KIA engine class settlement that the engine would be replaced free of charge and if it is not then I would have to pay $380 to have the engine repaired under the lifetime warrantly & that the car could not be looked at until December 16, 2024. Once December 16, 2024 came around I recieved a call from the KIA dealership and I was told that my vehicle could not be diagnosed due to the time frame in which i bought the vehicle and that I needed to have my car moved from their lot or I would get charged $80 a day storage fee so I had to have my vehicle towed back to my home where it is currently just sitting. To this day (January 22, 2024 I am still dealing with trying to communicate with KIA CORPORATE AMERICA to have this matter resolved for I am very aware of the engine recall issue for my specific year make and model. My vehicle has yet to be inspected and the only time the warning lamps came on was once the engine completely seized, all of the dash lights popped on.

The engine failed, and it is past the 100,000 mile warranty. Due to the fact that there were no warning lights at any moment prior to the engine failing, my safety and others were put at risk. The 2012 Kia Optima suddenly stopped in the middle of a major road, which could have easily caused a collision had another vehicle been any closer to me. The component was inspected by a mechanic, and there were no symptoms prior to the car stopping.

The contact owns a 2012 Kia Optima. The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic). The contact stated that while driving at approximately 80 MPH, the vehicle stalled. The vehicle was placed in neutral(N) and steered to the side of the roadway. The vehicle was towed to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Car went to limp mode and has code p1326. Car was towed to kia and waiting on determination of kia in korea to cover engine. Car has 63,000 miles

Driving on highway at about 60mph when the engine started knocking and the power decreased significantly. I pulled to the side of the road and called my day who came and brought his OBD 2 tester. The code was P1326 which is Knock Sensor. We had the car towed to a KIA dealer nearby and they updated the software. We picked up the car the next day. It seemed fine at first. Within two weeks the the same thing happened and we, once again had it towed to KIA. Within a few days, the service writer called and said that the engine needed to be replaced, but that KIA was denying an engine replacement. They said that they found sludge in the engine that in their opinion showed a lack of maintenance. We sent in receipts for oil changes every 5-6K miles. At this point, we do not have an answer regarding an engine replacement.

I started the car up no lights on, started fine, no warning symptoms like loss of power, no oil consumption nothing! Started an hour and a half drive to visit family and I started hearing a weird sound almost like plastic was flapping around on the bottom. Turned down the music and it was only making this weird sound every 5-10 seconds. Pulled off of the road shut the car off and checked under the hood, the oil everything seemed fine. Started it up and heard the sound again and suddenly became worse and came to the conclusion it’s a rod knock. Had to get off the busy road so continues for maybe 1 mile and every dash light came on shut it off waited for a trailer, once we got it on the trailer the lights were gone. The dealership near me is saying they can’t do anything due to a recall update not being done but I had a newly programmed ECU that was put in in March of 2023 and I was some research and i found a few things stating the ECU would be completely up to date but kia is fighting me on it. I have also been update to date on maintenance records. Since its been at the dealership I’ve asked for the other 2 recalls that are open on it to be done while I figure out what to do with it and they bypass me asking everytime.

The engine caught fire and exploded after I parked it and exited the car and the recall repair was done on the engine July 5 2024 by Kia dealership.

I was driving down the highway on my way to work and all of a sudden I lost power. The car was still on but it wouldn't go very fast and started smoking. Then a knocking noise started. I had to get it towed home. Car is not running. KIA refuses to take responsibility even though there is a known issue with this vehicle.

COMPONENT HAS FAILED. CAR IS NOT DRIVABLE AND THERE IS NO REMEDY FOR THE RECALL.

When attempting to acceleate rapidly, as if passing someone, the car will decelerate and eventually die, leaving you stranded on side of road or in the highway.

THE ENGINE QUIT WHILE ON THE HIGHWAY TO MY HOME. I WAS DOING THE SPEED LIMIT OF 75 MPH WHEN I HEARD A NOISE AND THE CAR STARTED LOSING SPEED. I COULD BARELY PULL TO THE SHOULDER OF THE ROAD. THERE WAS A LOT OF TRAFFIC AND THOUGHT I WAS GOING TO BE HIT BEFORE GETTING PULLED OVER. I THEN NOTICED THE ENGINE LIGHT WAS FLASHING. I HAVE HAD NO TROUBLE UNTIL YESTERDAY, NOV. 26, 2023. I HAD TAKEN MY CAR TO THE DEALERSHIP FOR RECALL #SC147. WHETHER IT HAD BEEN TAKEN CARE OF I WAS NOT TOLD. I ALSO WAS NOT TOLD THE ENGINE COULD BE REPLACED AT THEIR EXPENSE. THE REPAIR DATE WAS 11/22/2017.

A piece of carbon build up was caught on the exhaust valve not allowing it to close and causing no compression. The carbon build up is known in every kia engine as everyone knows they came out the factory with defects. With the exhaust valve burnt it scored the cylinder and none of it is covered under the extended warranty and I have seen many people with the same problem and all the dealership does is grind off the burnt oil on the exhaust valve and return it to the costumer while it is a ticking bomb. It is known to the dealership that this is a defect in the engine and which they told me on the phone while all calls are recorded. There was no sign that this was going to happened to the car. I was driving and the next second the car is shaking violently with the engine light on.
