I have never had any problems with my vehicle since the day I bought it brand new. I make sure to get regular maintenance and I am not a harsh driver. I was driving about 50 mph on a 2 lane road. The light ahead turned yellow and I slowed down to stop. Once my vehicle came to a stop at the red light, it made a weird noise like it was going to cut off but didn't. the light turned green and I began to press the gas and it seemed as if it was stalling and would not accelerate as quickly. The engine light, battery light and oil light popped on so I pulled over immediately, turned my car off and waited about 5 minutes. I crank the car back up and the only light remaining on was the engine light and my car started making a knocking noise every time I pressed the gas. I proceeded to go home and decided since it was a holiday I would take the vehicle to the dealership the next day. I went to crank my car up the next morning and the knocking noise had gotten louder. I started driving it to the dealership about a mile from my home but it turned off at a right light. I was too afraid to try again so I called aaa and had it towed to the Kia dealership. Since I was still under the 100,000 mile warranty, the engine was approved to be replaced. Two weeks later, I received my vehicle. This issue was very sudden and unexpected being that I have had zero other problems nor did any hazard lights appear on my dash beforehand. My VIN was checked for engine recalls and did not appear to be on the list.

While driving home my car completely shut off. No warning lights no nothing. I had a tow company try to jump start the car. Nothing. Had the car towed to a local shop. Checked starter, fine. Mechanic told me my engine was making a loud clanking noise, never heard before. He strongly suggested I do not drive the car. Had all oil changes done at dealership. Warranty expired. No help from dealership or Kia. I do not have $5200 to replace an engine. No car for 3 months

Driving down the freeway- car died- all dashboard lights came on- started back up-- had a knocking noise- drove it out of traffic and parked it. Towed to Kia dealership- engine is gone. Maintenance has been done regularly- the check oil light never came on - still isnt on- no oil in the engine- check engine light came on only after the car died.. this is very dangerous- the cars die in the middle of traffic

- Murray, UT, USA

I was driving on the street and with no warning my car stalled and shut off. I turned my car back on and it was okay, no lights or noises. The next day I was going to drive my car I heard a tapping noise coming from the right passenger side near the engine, but car still was functional. A few hours later the check engine light came on, the noise is still there.

2015 Kia Optima was going through 2 quarts of oil at least 3 times a week blowing out white smoke. Had engine replaced under 100K warranty at 98,844K. At 110,474 miles engine broke down while driving on highway. Managed to get car to shoulder and would only drive 5 miles an hour. Kia service department stated needs new engine and catalytic converter. States not in warranty. Kia corporate advised we have 12 month/12K warranty on new engine meaning there is approx 1100 miles remaining under warranty. Kia dealership now says that the original warranty for the car of 100K is what was covered for the new engine as well, meaning the warranty for the new engine lasted approx 1100. They are more concerned about the rental car they provided and reimbursement for that then the engine issue.

This has been a great car until suddenly I saw smoke. Checked my oil & it was low. I added oil. I began to hear rattling in the engine and huge white puffs of smoke emit from my engine, so bad that cars behind me on the freeway (all 4 lanes) hit their brakes as they cannot see. The 101 freeway during rush hour - this is very bad and could get someone killed, including me if my engine seizes at 75 mph. I check my oil every other day or so and seems to be low once a week. I've been waiting to drop my car at my mechanic. When I got there he said he could not touch my car due to the same exact reason for over 1.2 million recalled engines. I went to brake masters down the road asking if they know anything about this and they said "absolutely!" they told me do not do an oil change as many people's engine seizes within a day or several days after an oil change. Dealers consistently tell people their engine has "sludge" in it. Really? I have read so many reviews of the same diagnosis. Telling people it is $6,000-$8,000 for a new engine at their cost. Both my mechanic and brake masters told me that they feel the only reason my engine has not seized on me is because I took notice that my engine sounded slightly different. Not one time has a light gone off on my car. There is no reason why a dash warning light does not go off while loosing power and burning oil so bad that people cannot see. So, we have two issues..... #1 obvious failure of dash warning/engine warning lights and #2 the burning oil, metal shards ruining my engine. I am a single mom and do not get child support. I don't have a savings account and could not afford to replace an engine. I am very good with my vehicles and what I am reading is unacceptable. So many people are paying for new engines and I will not be one of them. Please help me as this engine issue is not a lack of care

2015 Kia Optima. Drove out of my parking lot and my car just cut off after I turned the corner at 4:30 in the morning heading to work. Tried to start it again it started and cut right back off. Had it towed to the Kia dealer in frederick. The dealer called me and said that my engine failed because it didn't have any oil in it and it had sludge and a crack in the engine. I was further told that I needed to bring all of my oil change receipts to prove I was getting my oil changed. My car is not even 3 years old. The warranty clearly states that you are covered 10years or 100,000 miles whichever comes first. Kia is not willing to honor their wairranty which is dead wrong. Got a call today stating that it was going to cost $7200 to fix my engine. Last time I checked I was not related to rockefeller. People just don't go around deliberately cracking engines. This car needs to be recalled. How was it recalled from 2011-2014 skipped 2015 and recalled again in 2016. I've been doing my homework with this situation and there have been 98 complaints about the 2015 Kia Optima which 48 of them where about the engine and Kia nor NHTSA had investigated any of them. That's because they do not want to fix there issues that they knew about prior to it happening. This is a true safety hazard and something must be done about it. It is not fair that we pay so much money for a car and then when something happens to it you can't even get it fixed. But I bet if it was one of those corporate peoples cars they would have no problem honoring the warranty or better yet giving them a new car.

I own a 2015 Kia Optima LX. This past weekend, I was driving home when my car just shut down. I then had to coast to the side of the road due to the car had no power. I turned the key off, and tried to restart the car again. But it just click once and that was it. It never would start again, I had the car towed home and put in my driveway until the next day. I called jeffery Kia the next day and had the car towed to them. After two days, the service manager called and told me that the engine had seize up and needs to be replaced. The car is only two years old with just under 60,000 miles and has a full warranty. But the dealer stated that since I did not have them do my oil changes that they required me to bring them receipts from other places to prove the oil was being changed. I told the dealer that I do my own oil changes, due to I don't trust oil change establishments. The dealer then requested that I bring them receipts from where I bought the oil and filter to prove that the oil was being changed. I told the dealer who keeps receipts like that!!! why would I keep receipts for oil that I bought at a auto parts store. I didn't think I would have to keep such receipts. But after doing my research concerning this issue with this make and model of Kia, I found out that this is a known problem. Back in 2014, Kia and Hyundai both recalled 1.2 million vehicles for this same issue. And it appears, that it is still no corrected. They should be the ones to cover the cost of the repair for this issue, since they knew about it from the start and failed to do anything about until it affected tons of innocent buyers.

I have a 2015 Kia Optima that completely died on me on 4/1/18. We were waiting to turn into a business parking lot and the engine just shut off in the turning lane. We tried jumping it and it did nothing. It was towed to the dealership the next day and before they even looked at it, they were saying the engine probably seized and said we need to get our oil change records together because we needed a new engine. They proceeded to try and blame it on us as we did not go to the dealership to have the oil changed. Who would think to save oil change records?! we've owned many different cars and never had to do this or ever had our engine seize. Kia will most likely refuse to replace the engine, even though it is still under warranty. To replace the engine, we were told it would cost $7,000 and possibly take up to a month to complete. I still owe money on this car and can't do anything with it. Since we're a one car family, we were forced to go out and buy another car last night. I'm disgusted with how we were treated and will never buy another Kia again. They should be paying off my loan because they were well aware of the engine issues in the 2011-2014 Optimas, and still sold us a car that was possibly defective.

Oil light warning displayed. Took it to nearest Kia dealership next day. Was told there was metal shavings in the oil. Engine needed replacing. Same diagnosis as the NHTSA campaign id: 17V224000 recall!

Engine failed on my 2015 Kia Optima while exiting the freeway. The car was making a knocking noise, started smoking, started to lose power, and stalled. I had the car towed into a Kia dealership. Kia issued recalls for this problem on several models through the 2014 models. They failed to issue a recall for 2015 models. They initially refused to honor the warranty and wanted close to $6,000 to replace the engine. Financially, this was not possible for me and I had to have the car voluntarily repossessed. I filed a formal, written complaint and explained the situation, including the fact that I had to have the car repossessed. At that point, they responded with a settlement agreement stating they would honor the warranty, if I released them from further responsibilty. This offer was not feasible, as I no longer had the vehicle. At this point, they told me there was nothing else they could do for me. I asked for a written response to my complaint and was told they cannot do that.

Metal found in engine. Vehicle completely shut off and would not restart. Has to be replaced.

The car engine died one day when I was driving up a hill in heavy rain on a very busy two way street with four lanes across. We're lucky we weren't injured because other cars coming up behind us couldn't see that well in the rain. There was never any knocking or indication of anything wrong. It just died out of the blue. We took it to Kia and they said the engine seized due to sludge. I had to get the engine rebuilt on my own dime ($3000 plus towing etc.) because Kia refused to honor the warranty. The car was only about a year old at that point. They told me I had to give them all receipts showing oil changes etc. And even when I brought the receipts they said it wasn't enough and that it was my fault. Not to mention Kia has already recalled this same engine in earlier models and it's the same engine (theta II) that is in the huyundai sonata which was also recalled for seizing/sludge. It is pretty obvious this engine is faulty and Kia needs to recall it but they aren't including this 2015 in the recall with the 2014, 2013 and 2012 models.
