POWER TRAIN, SEAT BELTS, VEHICLE SPEED CONTROL
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.

AIR BAGS, SERVICE BRAKES
The contact owned a 2007 Kia Optima. The contact stated while driving at 5-10 MPH, the vehicle before her vehicle slowed down suddenly. The contact slammed the brakes and the air bags deployed and deflated. However, the brake pedal hesitated to respond and became soft, causing the contact to crash into the vehicle in front of her. The contact was unsure whether there were warning lights illuminated. The contact stated that it appeared that the air bag deployment overrode the brake system and caused the stopping distance delay. There were no injuries sustained. The vehicle was towed to the contact's residence. The vehicle was totaled. A police report was filed. The dealer and the manufacturer were not notified of the failure. The failure mileage was unknown. The contact stated that what appeared to be a deflated airbag blocked her view of the road in the same moment that she slammed on the brakes. There was a delay in the brakes actually stopping the vehicle so as a result, her vehicle hit the vehicle in front of it. The vehicle is now a total loss. The contact was not aware that the dealer and manufacturer were supposed to be notified of this incident.

SERVICE BRAKES, ENGINE, POWER TRAIN
I'VE SEEN IN OTHER FORUMS ABOUT ENGINE RECALLS. I WAS NEVER NOTIFIED AND THE ENGINE IN MY CAR DISINTEGRATED. IT WAS REPLACED WITH AN ENGINE FROM A WRECKING YARD. THIS SHOULD BE COVERED BY MANUFACTURER. I HAD ISSUES WITH THE BRAKE LINES RUSTING OUT. THIS SHOULD NOT HAVE HAPPENED EITHER. NOT BEING ABLE TO SERVICE THE TRANSMISSION AND ARGUING WITH THE DEALERSHIP ABOUT THIS SHOULD BE REPLACED BY MANUFACTURER!

ELECTRICAL SYSTEM
VEHICLE BURNS OUT BLINKER BULBS AND HEADLIGHTS AT AN EXTREMELY ACCELERATED RATE: ONE A MONTH. ADDITIONALLY, THE WIRING HARNESS IS HEATED TO THE POINT OF BEING MELTED. THIS IS A FIRE HAZARD. I BELIEVE THIS MAY BE A VOLTAGE REGULATION OR GROUND ISSUE.

ENGINE
MY KIA OPTIMA BEGAN CONSUMING LARGE AMOUNTS OF OIL BUT IT WASN'T LEAKING OUT OR BURNING OFF ANYWHERE. I BEGAN TO WATCH THE OIL LEVELS CLOSELY AND WAS DOWN 2 QTS EVERY WEEK. AT SOME POINT THE OIL PRESSURE GOT TOO LOW AND WE THINK SUCKED AIR INTO THE ENGINE. THE CHECK ENGINE LIGHT CAME ON AND THEN OFF AGAIN AS IT HAS BEEN FOR THE PPAST YR BUT FOR AN EVAP PROBLEM - A VERY SMALL LEAK KEPT GETTING DETECTED. I SPENT $1800 AT FIRESTONE THE PREVIOUS UR THE COLDER KEPT COMING BACK ON AND OFF. BUT THIS DIDN'T EXPLAIN THE SIDDEN MASSIVE OIL CONSUMPTION. SUDDENLY ON OCT. 21 MY CAR SUDDENLY IDLED VERY HIGH WITHOUT MOVING AND THE THE CHECK LIGHT CAME ON AGAIN AND STAYED ON. THE ENGINE BEGAN TO KNOCK LOUDLY ESPECIALLY WHEN ACCELLERATING OR CLIMBING HILLS. MY MECHANIC FRIEND TOLD ME ONE OF THE ENGINE RODS WAS DAMAGED AND THE COMPUTER CODE CHECK VERIFIED THAT THE CRANKSHAFT TIMING OIL CONTROL VALVE WAS NOT WORKING PROPERLY. THIS WOULD EXPLAIN THE LOW OIL PRESSURE AND DAMAGE TO THE ENGINE. I WAS ABLE TO FIND THE PROBLEM ON KIA'S WEBSITE WITH MANY COMPLAINTS REGARDING THE SAME ISSUE. KIA HAD A RECALL REGARDING THIS PROBLEM FOR MANY OF THEIR CARS BUT OF COURSE NOT MINE. I WAS VERY UPSET OVER IT. I HAD GOTTEN THE CAR ONLY 3 YEARS PRIOR AND IT ONLY HAD 150K MILES ON IT. I TOOK REALLY GOOD CARE OF IT. KIA SAID THEY COULD DO NOTHING. MY ONLY OPTION WAS TO JUNK THE CAR AND HAVE TO BUY A NEW WHEN I WASN'T IN A POSITION TO DO SO. KIA HAS DISAPPOINTED ME GREATLY. BECAUSE OF THIS PROBLEM I MAY NEVER BUT ANOTHER KIA. I WAS SO EXCITED ABOUT GETTING MY KIA AS IT HAD ALL THE FEATURES I WANTED IN A CAR AND AT A VERY GOOD PRICE BUT IT IIS ONLY GOOD IF IT RUNS. THIS PROBLEM SHOULD HAVE BEEN INCLUDED IN THW RECALL FOR MY CAR AS IT IS A HUGE PROBLEM AS I READ COMPLAINT AFTER COMPLAINT ONLINE FROM OTHER KIA OPTIMA OWNERS. THE ENGINE COMPUTER CODE THAT CAME UP WAS PO600011

EXTERIOR LIGHTING
LOW BEAM HEADLIGHTS ARE TOO DIM. TRIED REPLACING THE BULBS, BUT NO CHANGE. CLEANED THE OUTER LENS TO IMPROVE CLARITY AND GET RID OF YELLOWING. BUT DID NOT HELP. THE OUTER LENS LOOKS JUST FINE. WHEN I REMOVED THE ASSEMBLY TO CHECK IF THERE'S ANYTHING WRONG INSIDE, I WAS SHOCKED. THE PROJECTOR BOWL HAD CAUGHT RUST ON BOTH SIDES, THUS CAUSING POOR REFLECTIVITY AND LOW LIGHT ON THE ROAD. TURNS OUT EVERY 2006/2007 OPTIMA OWNER HAS HAD THE SAME ISSUE. I FOUND THIS OUT WHEN I LOOKED ONLINE TO PURCHASE A NEW ASSEMBLY.
