I was driving my 2011 Kia Optima down a highway when the vehicle's engine suddenly shut off. The vehicle was in motion when this happened. I pulled off the side of the highway and tried to restart my car. The engine was knocking loudly. I called a tow truck and had it towed to my place of employment.

Without any warning lamps or extraneous sounds or engine noise, traveling approximately 40mph, the engine seized up and stopped. Immediately the engine, oil and battery lamps illuminated, and I was able to coast into a safe parking lot away from traffic. I attempted to restart the engine to no avail. Aaa was called and told to tow the vehicle to a local shop. Their diagnosis concurred with mine...the engine had seized and was not repairable except to replace the engine.

I was driving in highway in July 2017. The steering wheel was drifting and slippery. It was about 84,000 miles in it. So, I brought my car in Kia dealer. They showed me worn out steering coupling. I asked them to change steering coupling only but they changed whole steering wheel column and charged me $1,402. However, I found that Kia extended warranty for 10 years/unlimited mileage in 2016. I am not sure why they charged me for steering issue. I complained Kia motors America and sent all information that I have including the bills. They did not respond any letter yet. I like to have my money back. Another issue that I found in May 2018 was fast engine oil burn out. I was driving to work in highway and engine oil warning sign was blinking. So, I immediately pulled over and checked engine oil level. It was almost gone and so dark. The dealer just changed engine oil a few months ago and less than 3,000 miles driven after that. I filled up 3 quarts of blended engine oil and checked every other day. About two weeks later, it looks the level of engine oil was way lower (about 1 and half quarts were gone). I called the dealer that they said it was only engine oil burning issue not engine failure. They said it would not cover by recalls. I checked lots of complaining about engine failure issue from the internet. Based on that in many cases the engine oil burn out issue happened before engine failure. I strongly think that Kia should install new engine under warranty or recalls because I really concern about me and family's safety.

My Kia Optima 2011 has been having major engine problems but the dealers are giving me the run around they keep on making things up they said they drain oil to check for metal particles in the oil.N they said they did the SC147 recall I went to go pick up my car. I checked the motor oil it was dark N dirty meaning they never drained the oil afer they told me that my car had past the test.they said they can hear the knocking noise but N order for them to assist me further I would have to authorise for them to tear down the engine.ibut I would have to pay out of my pocket if its not the engine something regarding the recall engine failer problem.

There is an active recall on my Kia Optima 2011 and I never receieved anything in the mail to service it. The engine shakes a lot when the car is idle. Who do I contact with information about this recall?

- Michigan City, IN, USA

In March of 2017, Kia issued a recall for there engines in the Optima for the year I own. We still have not yet received any information from Kia about bringing our Kia Optima in for this recall. Our VIN shows that our car is part of this recall. A year later we still haven't heard from Kia. Our car is now starting to stall when we sit at red lights. We would like for Kia to finally reach out to us to remedy this matter.

Motor oil keeps disappearing; I change the oil on schedule and 2-3 weeks after it is dry. I'm afraid of engine failure or lock up due to this. Raising the hood does not show any oil splatter. Electrical problems; lnterior lights keep going out or go completely dim.

My car cut off in the middle of the street causing a accident

- Oakland, CA, USA

Beginning in spring 2017 my 2011 Kia Optima ex turbo (I bought it brand new, only owner) began stuttering while in motion (as if someone were pumping the brakes). The car stalls and dies at red lights and stop signs and needs restarted. It also stalls and dies while in motion, most disturbing in high speed, high traffic intersections and at 70 mph highway speeds. I will be traveling on high speed interstates and the car just dies and I have to hope I have enough momentum to safely get over to the breakdown lane without causing an accident. The check engine light usually goes on and off at least four times in between each service attempt. It has been analyzed and given attempted repairs by a Kia dealership four times since late May 2017 (see attached records), but the stalling and stuttering problems persist. I picked up the car from its last service on 10/18/17 and the same problems began manifesting again. This is now the fifth time. I have no idea what the problem with the car is (unknown) and it seems Kia's service help line for mechanic assistance does not either. The most recent time the car was at the dealership for service, Kia sent out a national service specialist to investigate the car, to no avail. 1) 5/31/17 - replaced map sensor (I paid $600 and it did not fix the problem) 2) 6/30/17 - tested grounds and replaced connections 3) 7/25/17 - replaced turbo and intercooler system 4) 10/12/17 - replaced engine computer 5) unknown - still problematic - asking for replacement vehicle from Kia the car has 91,410 miles and is still covered under the 10 year/100,000 mile powertrain warranty. This car is a major safety hazard, especially when it stalls and dies out in high speed, high traffic intersections and on freeways while traveling 70 mph. Kia obviously does not know how to fix it.

Started hearing my engine knocking the night before. Knocking still evident, followed shortly by 2 engine stalls on the highway! vehicle had to sit abandoned overnight until a tow could be arranged, which resulted in cancelling an out-of-state move!

Vehicle in motion on Florida I-10E doing about 70 mph. Car started making a ticking sound and gas peddle started pulsating. Tried to make it to nearest exit 112 but noise kept getting louder and louder and then there was a loud bang. White smoke appeared, engine and oil lights came on, and car completely shut down. Was able to move to side of road and called for tow.

- Port Richey, FL, USA

I was driving at 55 mph when the engine turned off. All electrical was working. I pulled over to the side of the road, and tried to restart. Nothing. No smoke, no clicking. Electrical system was fine. I had the Optima towed to the closest mechanic, when tried to turn the crank and found that the engine had seized. Oil was full, no over heating warning. I still owe on this car.
