2015 KIA Optima at 62,000 miles Lake Park, GA Crash 1 injured

The contact owned a 2015 Kia Optima. The contact stated that while at a complete stop at the red traffic light, another vehicle, driving off a highway ramp at an undisclosed speed, crashed into the rear-end of the vehicle. An unknown red warning light was flashing. The air bags did not deploy. The seat belts failed to restrain the contact as needed, causing the contact to hit her forehead against the steering wheel, which propelled the contact's head back to the headrest, and then the contact hit her forehead against the steering wheel for a second time. The contact was able to exit the vehicle but felt dizzy and off balance. A police officer filed a report and informed the contact that the vehicle was safe to drive. The contact was able to drive the vehicle to the nearby hospital, where the contact received medical assistance. The vehicle was later driven to the residence, where it remained parked. The contact sustained a concussion, bruises on the forehead, neck, and lower back back pain, a worsening of the contact's generative bone disease condition. The contact might undergo a back surgery. The vehicle was towed to an independent mechanic two months later. Both the mechanic and the insurance company confirmed that the vehicle was totaled. The manufacturer was notified of the failure and informed the contact that the vehicle operated as designed during the incident. The contact was referred to the owner's manual.

The issue concerns the rear center seatbelt used to secure infants and small children. The seat's "racketing" restraint did not disengage when the belt was unbuckled. My child became trapped and I had to cut the seat belt with scissors to get him out.

2017 KIA Optima Portland, OR

SEAT BELTS

Engine is burning 2 QT of oil every month and burning it in under 1000 miles. Kia dealership says it's a common issue but can't help me until the engine seizes up. The car has less than 85k miles on it. How can this be a common issue but they can't fix it till the engine dies? What if the engine dies out of warranty? Then I'm out 12k for a new engine that will die in 80k miles. This should be a recall.

2007 KIA Optima Coopersville, MI Crash

My vehicle speed up and slow down all that itself. It will not maintain speed even with my foot steady on the gas. It will not accelerate, but the major problem is my seatbelt gets stuck all the time I’m afraid to get buckled. I am unable to remove my seatbelt multiple times so now I have buckled my seatbelt behind me so I can start getting tickets. I’ve gotten like four tickets because I’m scared to be buckled that it’s not gonna come on down when I need it to be I’ve got 40 bought tickets. I was going about 20 mph when I went to the brakes for my vehicle accelerated by itself crashing into a pillar at the mall. I did call the police.

2013 KIA Optima Camden, NC Crash 1 killed

SEAT BELTS

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.
