My son owned a Kia Optima built in June of 2013. He was in a motor vehicle accident where he was put in a pit maneuver and Then was T boned on the passengers side causing his body to lay across the front seats and died at the scene. His black box download showed that the seat belt pretensioner was off and both airbags in the front did not go off. I know there is a recall for optimas built before aug 31 of 2012. I believe there was an issue with this vehicle as well. I would hate for there to be anymore deaths or injuries with the later models of these vehicles. I do hope this is looked into further.

I was rear ended hit so hard it smashed my whole back end in. None of my airbags deployed. We were hit hard into the center medium of the highway. Lucky no rigs were coming through. Other parties insurance totaled out my vehicle.
My paint has been chipping really bad. Also I had a few recalls taken care of at modesto Kia once I got my vehicle back and drove it back home (about an hour and a half away) I started smelling something burning, I looked under the hood and couldn't find anything wrong so then a few days later I smelled the same thing but this time I heard a loud pop I got out and noticed my fog light had shattered, and the housing is completely burned. So now my fog lights won't work and I have to make sure the fog lights are turned off because I don't want there to be power going to the loose wires, the head lights get extremely hot to the touch the fog light got so hot it burned a hole through the bumper. Then about two weeks ago the airbag light turned on and it won't turn off, I did some research and found out that when the air bag light is on there is a huge chance the airbags won't deploy. …
I am terrified the car is going to catch fire. You can fully inspect if need be. Most of the electronics in my car malfunction, since the start of buying it, windows roll down but not up from front button, sometimes my sunroof will open randomly, or when going to close will just reopen, my seat buttons dont always work, etc. But the newest thing that is scaring me and doesnt seem to be just cosmetic like the other electronic things it my air bag light randomly coming on, my driver air bag light comes on and the moment it does my passenger air bag light turns OFF with nobody in the seat. So Driver airbag will NOT be deploying but my passenger one will, with nobody in the seat. On top of that it vibrates and rough idles so badly its actually randomly turned off in the morning when i first start it. I have had my engine replaced and upgraded, and my turbo replaced already. …
I own a 2013 Kia Optima SXL. While the vehicle was parked and there was no collision, crash, impact, or other event that should have caused the airbags to deploy, the airbags unexpectedly deployed on their own. The deployment caused damage to the vehicle, including damage to the windshield. The airbag also hit me while I was sitting in the passenger seat, my children were also in the back seat. All of our ears were ringing for 24hours, I went to the hospital to get a CT scan for the pain I felt in my face, ear and head. This occurred without the vehicle being involved in an accident. I have photographs and documentation of the vehicle and the damage and can provide additional information if needed.
