My driver's seat seatbelt has completely locked up rendering unusable. It neither retracts or goes out further so it is stuck in a state where it cannot buckle with a person in it. My car is only 7 years old and I have only had it for4 years.

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.

NHTSA complaint #11622702 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11568114 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11540312 — an unverified report by a vehicle owner.
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.
