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.

Vehicle in motion on Florida I-10E doing about 70 mph. Car started making a ticking sound and gas peddle started pulsating.

Was able to move to side of road and called for tow.

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.

Problems starting a few years ago. Heard knocking, brought it in for recall, and it wasn't doing it anymore. Had problem with emissions. Recall was done and I was told that the problem led to engine problems. Now engine is burning through oil, and local trusted mechanic says it is going to need a new engine by winter. In research have seen others are having similar problems.
