Selected complaints filed with NHTSA by 2011 Kia Optima owners, lightly cleaned up (personal details are redacted by NHTSA).

There's something going on at the Kia dealership in Wake Forest (Westgate). Per the current recall notice, the lights came on that were highlighted in the notice ( "MIL" , ABS warning light) so I had my car towed into the dealership. They claimed my car had a bad battery and the problems were not due to the recall situation. I took my car out of there and straight to auto zone, about 200 feet from the dealership. My battery tested fine. Not only this, the lights (check engine, and others) were no longer illuminated and the radio was mysteriously working again. I'm not sure what they did to my car, but they charged me over $200 for a diagnosis. Not only this, they cited several other issues with the vehicle that I nor my master mechanic were aware of. They had my car for several days without so much as a phone call. …

About six months ago, I lost the heated steering wheel functionality in my steering wheel, then from there, I slowly lost functionality like cruise control, and the most recent now my airbag and horn do not work. If you press on the horn, it is silent, and the airbag light has been illuminated consistently for the last couple of months. I had this issue diagnosed and it came up with the codes of B1346. And B1481. After some research, these issues are the result of a bad clock, spring and cause the airbag and horn not to work. Additionally, this issue is known to this model the 2011 Kia Optima, and has been recalled in most production cases of this vehicle, but my vehicle is not included. I received a quote for $876 from a dealership to get this corrected, but it should be included in the recall.

I was sitting in a turn lane, to turn left. There were two lanes to my right for traffic. I was waiting for a car coming from the opposite direction. I happened to look in my rear view mirror and it was completely taken up by this red object, which happened to be a car. Immediately I felt a terrible shock and my car was lifted up in the rear and the front end pointed at the road. This car drove me approximately 40 yds. Up the road. The air bags did not deploy...none of them and there was $12,000 worth of damage done to my car. I still have lower back pain and severe cramps on the left side of neck and head.

My son was driving his 2011 Kia Optima when a spark and pop noise came from his steering wheel. All the functions of the secondary functions of the steering wheel, including the horn, air-bag, cruise control, etc. Quit working. I took the vehicle to Kia and they immediately diagnosed the issue as a clock spring without looking at it, which makes be believe this is a common problem. If my 16 year old son had been in an accident, he would have not had a frontal airbag. And without a horn, he would not have been able to warn another vehicle appropriately. This is a major safety issue and Kia has done nothing to rectify the problem.
