Thankfully I was driving down a back road and without any warning my 2012 Kia Optima hybrid made a loud knocking noise then slowed down and when I pulled over I had a "hybrid battery low" light come on so I have the car towed and replace the battery, still not working. Now the battery light is off but now there's 2 other lights that come on. 1 said "hybrid system warning do not drive" and the other says "check charging system" so I have it towed again but this time to a Kia dealership. They called me back the next day and told me that it appeared that my motor seized. They couldn't tell me how or why.. my car only had 75,045 miles on it. So I contact Consumer Affairs because I heard about the recalls. They even told me that my car was mimicking exactly what the optima recalls were doing. However, because mine was a hybrid it didn't fall under the recall. Which I thought was very unfair. Still nothing they can do, they want $6,200 for a used motor. Mind you I've had the car for 3 1/2 years and have kept up with oils changes etc. Next I found out that I had an extended warranty... but of course it expired 45 miles ago. Again, not fair. Nobody seems to care or want to help me. This is very inconvenient. Now I'm without a car that I'm still making payments on. I'm very disappointed in Kia and their customer service. I feel as though if my car was doing exactly what the recalls were doing with the same size motor then how come they won't cover mine to be replaced? I almost want to hire an attorney and have this investigated. I still want to know exactly what is wrong with my car! nobody has answers....

Without warning the engine overheated while driving in the highway. The engine made a loud noise and began smoking... the vehicle became immobilized I pulled off to the side of the road and opened the hood. There was so much smoke. The car turned on afterwards but the engine did not start. Within seconds the battery shutdown.

For the past year my car has had a problem losing power in the middle of the freeway, very dangerous, dropping from 70 mph to 40 with no acceleration forcing me to put on my hazards and pull over. Ive taken it to dealerships and payed over $700 for them to tell me they couldnt find anything wrong.the engine oil light comes on thousands of miles before its time to be changed. Today on the street after exiting the freeway, the car started shaking profusely while at a stop sign and the enigine light came on with a warning that stated 'hybrid emergency do not drive' I turned my car off at the stop sign, again, dangerous as it was middle of traffic, to stop the shaking. Turned ot back on and proceeded home which was about 800 ft away, the entire time the engine light was on. The car began making a chirping noise as I drove home. This is ridiculous and dangerous and even though online it states there was an engine recall for 2012 Kia optima, my VIN # states no recall. What should I do?

- Houston, TX, USA

Engine locked up @ 100,104 miles. Car was maintained meticulously. Never missed a oil change. Kia replaced the hybrid engine @ 80K. A year later. My family is driving down I-85 @ 65mph when the engine starts smoking and making some loud sound. The engine dies. We by the grace of god, get to the side of the highway and coolant is pouring out while the engine is just pouring smoke. The hybrid warning system is flashing. Have it towed to Kia. Kia stated internal engine failure. Refuses any goodwill or assistance. Wants $4500 to $8000 for a new engine. These are the same engines that got recalled but built at a different plant. The hybrids were not included in the recall. Just a matter of time before someone gets killed by Kia's corporate greed. I'll never buy another Kia product. Ever.

Hello. I have already posted a complaint to this website and I am simply trying to find out why a very noticeable pattern of defects is going unnoticed on these Optima hybrid engines. 3/4 of all the posted complaints for the 2012 Optima hybrid are due to engine failure from connection issues caused by worn bearings. These are the exact same part failures that lead to the engine recall for standard optima gas engines. Why is NHTSA not contacting Kia and forcing their hand on recalling the hybrid engines" there are obvisouly less hybrid optimas than non-hybrid, but the failure rate is just as high or worse than the non-hybrid model. I do not believe hybrid owners should be subjected the risk of an engine failure just because there are less of us. The second issue is that many of us have already replaced our engine because they failed. Either paying in full or with some help from Kia, what happens when the new engine fails for the same reason because they were not recalled an forced to recognize the failure and design a fix that will keep it from happening to the replaced engines" I am such a huge fan of Kia I own 2 optima's. the other is a gas model that has a replaced recalled engine. I had to pay out of pocket to replace the engine on my hybrid. We are begging for someone to look into the extremely high number of engine failures on these Optima hybrid with virtually the same engine as the gas models. Kia claims the engines are different, and they are to some extent, but they share a lot of parts, most of which are the parts that are failing and design flaws. Thank you for your time, I hope someone is actually looking out for the public and reading these post.

While driving on a highway around 45mph, the engine suddenly made a rattling noise, then shortly after, made a loud squealing noise and then a sudden jolt. The car shut down and showed an error about the hybrid system malfunction and I experienced a quick drop in speed and was unable to accelerate. After pulling over, the car would not start. Car was towed to dealer and they were able to start vehicle, but it makes a loud 'clanking' noise and car vibrates. Dealer informed that appears a part inside engine had failed and will need complete engine replacement.

The hybrid system broke down at 85K. Was replaced by Kia after threatening legal action. At 103K. We never missed maintenance or a oil change. The engine through a rod on a 5 lane interstate doing 65mph, blowing and destroying the engine. Putting my family of 5 at serious risk. Kia wants 4500K or 8000K to replace the faulty engine. Optima engines were recalled for this exact reason. The Optima hybrid engines were not recalled despite suffering the same failures as normal optima engines. Joining the class action.
