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. In addition, while I was waiting for the keys to my car (which took 15 minutes to obtain), I overheard the other gentleman inform a kia owner via phone that her car was not covered under the warranty because she had over 150K miles on the car. I'm so disgusted. This is what happens every time we have to take a car into a dealership. They're full of baloney.

While driving on the road, I came to a stop at an intersection. While waiting for the green light the engine stopped running. I tried starting the car by pressing the brake and the push start button and the car only clicked and did not start. I pushed the car off the road. After several attempts to start the car it wouldn't start and it started smoking it looked like it was coming from the starter location. It appears that the engine seized and it won't turn over.

A recall has been issued for my 2011 Kia Optima. I received a letter from the NHTSA with my VIN on it. I am concerned about the safety of me and my family. I am being told that there is no remedy for the HECU. The recall says it can experience a fire in the engine compartment while parked or while being driven. I find that possibility quite scary. What am I to do? What is considered a reasonable amount of time for this to be fixed? The recall was issued nearly three months ago. Each day gets more and more frightening.

My car won’t crank. Starter is not working. Ask if warranty or recall. Let’s see if they accept warranty for starter replacement. My car towed to Kia of Lincoln in Lincoln, Nebraska where the car parked there right now. Please contact Kia at Lincoln and I better hope warranty are accepted and diagnostic are free too. Thank you!

It appears I have a defective oil pump in the car which I think is what caused the engine to go bad to begin with. I am requesting that KIA of Denham Springs be authorized by the main office of KIA to install a new oil pump in my car after the new motor is installed, otherwise the new motor will probably go bad and will result in Kia having to install another motor for the car. I hope you can step in and assist me in getting a new oil pump installed as this would be a safety issue of the car breaking down on the road and could result in myself or other passengers possibly stranded on the highway . A engine compartment fire could happen if the engine gets too hot due to the deflective oil pump no keeping all engine parts oiled properly by the defective Oil Pump. I am requesting that the National Highway Traffic Safety Administration's office look into this matter. Thanks for your assistance Tommie McMorris 985-969-8995 email: tommieap@charter.net

Low beam headlights on my 2011 KIA Optima with 150,000 miles are bright to look at them, however the beam pattern on on the roadway is terrible. I have tried replacing the bulbs with brightest bulbs, checked voltages and grounds. After checking over 10 forums I have found that the reflective service on the headlight housing has degraded and lost its reflective value causing a very safe condition. 1 person disassembled the headlight unit and installed foil tape, stating this corrected the issue. I have attempted to contact KIA with out a return response. I feel this should be a KIA recall issue.

The headlights fail to light up safely and can cause serious injuries or even death. You are unable to see 10 foot in front of the car on deem and bright lights you can only see 15 feet at the max.

After driving the car over 15 miles, the Check Brake Light comes on, activating my emergency brake, slowing the car down and preventing me to accelerate. This happens on the freeway, where traffic is fast and my decelerating car puts me and those around me at risk of collision. Once it occurs the first time, it happens again a few minutes later. I have to frequently veer off the side of the freeway, turn off the car, and then turn it on again for the Check brake light to go away and for me to travel once more. This has been a problem for a couple of years with me trying to get the issue repaired, and documented in my visits. Kia and other service operatives have repeatedly not been able to replicate the error in their care, however they never drive it long enough for it to occur. I’ve spent a lot of money now trying to fix this problem and have videos and photos of it occurring. The last time it was inspected they only drove it 6 miles and said there were a lot of little codes going off but weren’t again able to replicate the problem I had been describing. It first appeared 2 years ago and I can feel it start to come on when I’m not able to accelerate my car any further like there is an added resistance. This then amounts to the check brakes display to appear with the emergency brake icon always accompanying it. It makes a scraping, gargled sounds and slows down the car. Overall it has affected the overall drive of the car and braking system as it is growing harder to stop the car when driving. The brakes have been repeatedly checked as well as the fluid and it’s normal, so it should be braking normally. This car has had other issues in the past that have been fixed but this has continued and has been a growing issue that is not being resolved. I’ve googled this issue with others expressing the same issue without ANY viable solution from Kia so I know I’m not alone in this. It’s not safe to drive. Also I tried uploading the videos but it only allowed the pictures.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2011 Kia Optima verdict →
