2012 KIA OPTIMA Engine Problems

•I’m not sure what failed, the car was parked. And yes it’s available for inspection. •I had just parked the car coming from work and at the time. 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.

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.

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...

Bearing wear resulted in the engine seizing.

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.

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,...

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.

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...

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...

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...

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).

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...

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 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...

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.

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.

My vehicle has not repaired. I have not been in an accident. However there are two open safety recalls for my car and I am terrified that myself or someone else is going to be injured or even killed due to this problem has yet to be resolved. The first recall for my car is the headliner plates. I took my car into my local dealership (Stokes Kia of Goose Creek) and they told me it would take 10 business days before they could inspect my car and determine what the problem is (it’s a recall so I don’t understand why they would have to identify a problem that was clear in recall letter). However, I asked if they would repair my car within that 10 day period if they “identified” the problem. They told me it could take an additional 10 business days or longer for the repair (for...

Was driving on the road on the way back to work from lunch, started hitting the brakes at an upcoming stop light, and the car shut down. There was no lights indicating anything prior to the incident. I tried starting it again and it started smoking, I then opened the hood and all the smoke poured out. The engine bay smelled like something electrical melting or of some sort. I towed it to the dealership I work at and had my ex-kia technician coworkers look at it and said they've never seen anything like it, but did confirm the smell was electrical. OBD II reader was not reading anything at all. I was letting it sit for a while waiting for the recall to have some sort of remedy, but I've grown tired waiting so I decided to file a complaint. And I will reiterate again that NONE of the...

On September 27, 2023 I was driving home at 50 mph on 41st & Lynn Lane in Tulsa, Broken Arrow, OK. The car just shut down right before I had to stop at a stop sign. Not being mechanical minded the only thing I could think of was to call a towing company (AAA). I was informed to also call 911 to have a police officer come and block traffic to keep me from getting hit. It was towed to the only garage there is close to my house as the Ferguson Dealership couldn't take it at the time. It was at a place called The Garage. They at the time told me they thought it was the fuel pump and replaced it. The work was done on October 2, 2023.

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.

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...

We have tried numerous times to get Vanguard Kia in Arlington, TX to address the recall on the engine. They have only updated a short term fix which is a software update. It will be 2 years in October that we have been trying to get the recalled engine replaced. They updated in their system that they replaced the engine but the same old engine still remains in the vehicle. They have charged us for many other repair issues and now tell us they don’t know what is wrong with the vehicle and can offer no solutions. We have repeatedly asked for them to correct their error and they refuse. I believe individuals working for the dealership may have fraudulently reported addressing the recall engine and may have kept it. We have reached out to Kia and have not heard a response. Is this legal?

I tried to speak with Kia about a recall the engine on my making model I remember seeing it on your guises website this issue was never fixed and I’m currently having issues with my engine and they’re refusing to replace it. I’m trying to avoid a lawsuit and a serious accident because of the way my car is acting up. It is accumulating me a check engine, light, as well as a oil light I’ve brought the car in many times to vanguard kia and they could not figure out what was wrong with the car , and holding it for week the two times i brought it in and it seems as if you’re continuing to drive it is creating more issues because I had to pay $1300 out of my own pocket because my engine started overheating because it has a problem that kia could not find...
