Upon acceleration the motor seized and started smoking. I had to quickly apply the brakes and get off the interstate due to an 18 wheeler being right behind me.

On Aug 2nd I was driving thru Utah on my way to tn. I car starting having some sputtering/hesitation issues when going from a complete stop. I there was no warring on my instrumental panel. All electronics (ac, radio, etc) were working fine. I continued on and shortly there after my car started not accelerating at all while driving down a major freeway. I had no power at all. Still no warring on the panel. I managed to get off the freeway and barely made it to a side street near a gas station. I was almost hit due to the fact I couldn't accelerate my car. I preliminary inspection of the car by a mechanic reveled that I had a blown motor. I got it towed from the mech shop to the dealership, and began working with Kia Consumer Affairs. At present I am being told that this is a maintenance issue and not part of Kia's motor issues. However I always get my oil changed with full synthetic oil and a Kia oil filter. This is done about every 5K miles. Additionally I had Kia do the 90K mile recommended service on the car. This is not a maintenance issue and so far Kia has refused to fix or acknowledge their poor manufacturing of this turbo gdi motor.

The contact owns a 2012 Kia Optima. The contact received notification of NHTSA campaign numbers: 18V363000 (air bags) and 18V907000 (fuel system, gasoline, engine). The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair as the recall notice was received over a year ago. Gervais Kia (6 industrial ave, lowell, MA 01851, (978) 454-1202) was contacted and confirmed that the parts were not available for the recall remedy. The manufacturer was contacted several times and was unable to confirm when the parts were to become available. While driving 20 mph, the contact noticed an abnormal clicking noise coming from the steering wheel and the engine stalled. The contact had to veer to the shoulder of the road to turn the vehicle off and back on in order for the vehicle to resume normal operation. All the warning indicators illuminated. The vehicle was taken to the same dealer who confirmed that parts were unavailable. The dealer updated the engine module software, but the failure recurred. The manufacturer was contacted and provided case number: 13157669. The failure mileage was approximately 80,000. VIN tool confirms parts not available.

While driving on the highway my 2012 Kia Optima hybrid slowed down to 45mph and engine started to make noises. This came with no mechanical warning, no "check engine soon" or other warning lights, and had been driving perfectly before it was parked. Checked oil and oil level was perfect. Called mechanic and he asked me to take a close look at oil. Oil had small shiny metal shavings on stick that transferred to fingers when rubbed. Had car towed over 30 miles to nearest Kia dealership. Car was diagnosed with "engine failure" due to rod end bearings. I am the 2nd owner of this car the I bought from a master mechanic at a Lexus dealership. We are very meticulous and take very good care of our vehicles. This is not a owner problem. Dealership wants $10,000 for a new motor, $4,000 for a used (although there are none currently B/C there is a shortage), or $6,000 to rebuild current motor. Service manager was "surprised" to hear about the metal flakes as they didn't see that during the diagnoses. Both Kia dealer and Kia Corp are standing behind the no recall on hybrids. Said although the engine is the same, they were made in different factories, but could have shared the same parts. Service manager stated, "you have a lot of miles on this car"......146K.......I mean, if I can not trust to get 150K out of a Kia why would I ever want to purchase one again"?" I asked him to explain how this could happen and his response was, "it is a mechanical piece of equipment". Kia needs to stop putting blame on its owners and take responsibility of their faultily engines for the hybrids as they have on the non-hybrid models. There are too many other complains having the same results and stories for this to be an owner problem. It has been a month now, and no one is budging.

I have a 2012 Kia Optima hybrid. Drove great at first now the car is off and on.. while driving the car lunges often and as others have said there is a delay 2 second from pressing the gas to the car actually accelerating. The car also loses power when driving on the highway. I've noticed the engine will not charge the hybrid battery when it is getting low and the car become immobilized unable to accelerate. I have had dash lights only appear once and when the car was taken to the dealership they were unable to find the cause. This issue is extremely dangerous to myself and others. Attached are a few pictures you can see the hybrid battery had 1 bar it appears to be charging but then goes to 0 bars because the battery is trying to power the car while only the engine should.

When the accelerator pedal was released and depressed again, the vehicle would accelerate normally. In addition, when accelerating from a stop, the vehicle started to rattle, the oil warning indicator flickered, and the rear brake lights would remain illuminated when the vehicle was turned off.

Driving on the interstate going about 80mph. The engine seized and all the warning lights came on in the dashboard. Car lost power and had to coast to the shoulder of the road and use the emergency break to stop. Tried to restart the car right after heard clicking noises like the car was trying to turn over. After waiting about 20mins I tried restarting again its started without issue. And I continued to drive to my destination. The next day driving on the interstate again I tried accelerating to about 60mph and the engine stalled and I heard knocking noises coming from it immediately. Pulled over and got it towed from there. Prior to this I never experienced any engine issues and never had the engine lights come on. Car only has 44K miles.

In 2017 we had the Kia towed to selma Kia motors because of the recall of the engine, because of shaving in the engine and our turbo went out and was burning.the car stop on us in traffic on a city street we could of died that day. They had to order the engine which took two months. They finely put the new engine in. April 2019 the same thing happen again, they told us there was shavings in the engine once again and the turbo was out also, that was another defected engine. They also told us we had another 10 year warranty on this engine because it was new. Well they called us and said that the corporate office in irvine told Kia in selma not to fox this car. What irvine corporateofficetried to do to us was black mail us, they said if the give us $12 hundred dallas that we cant go to the attorney general, the manufacturing plant, tv or any other consumer department. We refuse, this type of thing going on. People lives or being taking because of this defected car. We paid $30,000 dallas for that car, that's clearly a defect car. We contacted the attorney general, office once again and 20/20. It seem know matter what there is no help out here for the hard working consumer I'm a veteran also, this is how the country treat us we fought for this country. I need your input on this situation as asap. Sincerely, [xxx] redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My 2012 Kia Optima sx-tgi is in 'limp home mode' due to a sensor in the engine that detects some sort of engine problem. But it's not specific on what it is. Now my wife cannot is her car that she has had only for a few years. It has already had two manufacturer recall repairs and now I feel like there is another defect that is explained in a few articles online where the engines had caught on fire. And this 'limp home mode' allows the driver to drive for a short period of time at low speeds to keep from further damage. These engines were replaced on Kia's like mine that were manufactured within a certain time frame. Please be aware it's a very scary matter.

Engine is making knocking sound. Sounds like piston. It's a 2012 and keeping up with oil changes and tender loving care. It's 7 years old there's no reason the engine should be knocking and turning off in the high way at speed 65 mph with my children in it. I am very mad this should be taken care for free (xxxxxx) parts of this document have been redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
