2007 KIA OPTIMA Seat Belts Problems

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.

THE AIR BAG LIGHT STAYS ON ALL THE TIME 1 THE PASSENGER AIRBAG LIGHT WILL SAY ON WITH AN ADULT SITTING IN THE SEAT!!1 VISORS DO NOT STAY UP! HEADLIGHTS ARE VERY DIM . I'VE CHANGED THEM OUT TO A FEW DIFFERENT TYPES STILL DIM CANNOT SEE AT NIGHT
