Vehical has had problems starting in cold weather for 3years now. We've taken the vehical to a Kia dealership numerous times only to be told they don't know what's wrong with it or (it would do it for us/ well it started for us). Most recently the vehical was at the dealer ship for 10 days while we were vacationing and they returned the vehical only for it to not start the following morning. It's a push to start and as a safety feature the brake pedal must be pressed in order to start the car. When the problem first started there would be a light on the dash that would indicate there was not key witch was not the case. You could have the key phob in the car and still wouldn't start. This was only on cold days. It would start just fine unless it was below 20 degrees. More recently the car will show no indicator on the dash and won't start if the temperature is below 30-35 degrees. Above that everything works fine. We changed keys and replaced batteries in keys and moved them all over the car but nothing would get the car to start until the temperature rose above freezing. Most recently this morning I went outside to start the car (around 30 degrees and rising) as I pressed the brake and hit the start button I heard sparks and a loud poping noise followed by hissing and sizzling the vehical then began to fill with smoke. I exited the vehical and took a few steps back. About 10 seconds after initially hitting the start button the car then started with me standing about 20ft away while still smoking. I never saw flames but could smell an electrical fire and was waiting for the car to burst into flames from the amount of smoke that was coming from it. Majority of the smoke seemed to becoming from driver seat area (underdash and along driver side quarter panel). After a few minutes the smoke died down and the event seemed to be over. I haven't touched the vehicalsincemornin

In November 2017 I continuously took my vehicle back and forth to the dealership due to my vehicle not started, and/or needing a jump. Jim marsh Kia had me replace my battery after 6 weeks of complaints and complications. Only for a week later to have me and my kids life at risk, heading South bound on I-15 my car flashed a warning sign stating do not start engine hybrid battery undetected and shut off while a semi truck was behind us. By the grace of god I was going down hill so I swerved to the side of the dessert and road to spare our lives. Just to have Kia tell me 4-5 different excuses as to why my engine failed.

Clockspring failure causes on-steering wheel controls to fail. Kia service did not find any service codes produced when the steering wheel volume control switches, cruise control switches and cellphone switches displayed intermittent functionality. Failure of the switches generally displayed upon initial start of the car after sitting overnight or at the end of a work day. Temperatures were consistently over 100 degrees F. during an approximate 1 hr 15 min surface street and freeway commute (each way),switches would function after a few minutes driving, but then fail again. Correct functionality was inconsistent. And did not persist. Car was taken in several times for these issues but no codes were produced. Service rep suggested that the clockspring may be involved, but recommended only the replacement of the faulty switches. Volume and cruise control switches replaced, but again showed intermittent failures that would not produce codes. Finally, the replacement volume switches and the cellphone switches completely failed; again, no codes were produced. Kia service noted that the clockspring is integral to the correct functioning of the steering wheel airbag system along with all the steering wheel switches. Kia service now confirms that a faulty clockspring shorted out the steering wheel switches; a new clockspring, volume controls and cellphone controls are being installed. Again, prior to the repair, no codes were generated for Kia service to observe. Prior to releasing the car, the switches were checked for correct function, but failed. At that point, the clockspring replacement was initiated. Note: Kia service also performed the recall work on the acu wiring harness during this service incident.

My car just turned off with several flashing lights while driving. I tried to start the car and nothing but a slight tick. I returned to the car with jumper cables to see if it was the battery and before I tried the jumper cables I tried one more time to start and the engineer caught on fire. The car did not turn over or seemed to be running.

'takata recall' I'm currently buying a Kia Optima 2012 and everything was working fine and had maintenance up to date at Kia of orange. Then I did full service which I payed 600$ or so and after the car started giving me problems, I went to my friends house and my boyfriend got off to get tools from the house it took him ten minutes to come back. The car was on and I was windows up and ac on when he came out he saw fire under the front left light. It got on fire and we were scare for our life's and we manage to run around and find anything that will help we had water and it wouldn't turn off, we didn't know it was electrical so it was melting plastic until we manage to find a fire extinguisher while I was calling 911 we thought the car was going to blow up. Second of all we fix it insurance cover. We call Kia they told us our insurance had to pay it. So we did next I took it to get maintenance update and oil change, we took for a drive to chino hills California and then the car turn off by it self on the freeway I was 65 speed limit and my steering wheel got hard and all the lights were on. I could of lost my life. I manage to move it slowly to the side and it was on fire when I open the hood something was burning again. A sheriff help us turn it off with his fire extinguisher. The engine had blew up a wrot blew maybe because of no oil or idk I'm not mechanic that's why I take it to Kia. I believe they didn't do their job right and my insurance doesn't wanna cover it, now I'm careless and I have a daughter to feed and I need help to get this out there if anybody has the same issue please make this go viral.

Due to a recall, I had my engine replaced by Kia patterson in July of 2017. About a week or so after getting it back, the airbag light came on and the horn does not work. Naturally, I contacted Kia patterson regarding the matter and was told that it had nothing to do with the engine replacement. I'm now being told that it may be a defective airbag or clockspring, both of which are expensive repairs. I have found that several Kia vehicles have suffered the same fate with no resolution. My car does not fall into the previously recalled models yet it seems to have the same problems. My level of frustration is so high at this point and I don't feel safe driving with these problems. Unfortunately, I will have to do so until I am able to save enough money to have it fixed. Shame on you Kia!!!
