Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

2007 KIA OPTIMA. CONSUMER STATED THAT THE AIRBAG DID NOT DEPLOY DURING COLLISION. THE CONSUMER STATED THE VEHICLE WAS TOTALED AND TAKEN TO THE JUNKYARD DUE TO THE PROGRAMMING DEFECT.

NHTSA ID 11504643 · filed Jan 31, 2023

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.

ON TWO OCCASIONS (TO DATE) MY KIA OPTIMA HAS BECOME INOPERABLE - UNABLE TO PUT THE CAR IN DRIVE OR REVERSE. THE FIRST OCCURRED DURING THE WINTER IN FEBRUARY 2010. AFTER ONE OF MANY SNOWSTORMS THIS SEASON I WAS DRIVING ON A PLOWED ROAD THEN ENCOUNTERED AN AREA WHERE THERE WAS ONLY ROOM ENOUGH FOR ONE CAR TO PASS. WHEN I PULLED OVER TO ALLOW AN APPROACHING VEHICLE TO PASS MY CAR WAS IN ABOUT 8-INCHES OF SNOW. WHILE MOVING THE TRANSMISSION SELECTOR BETWEEN REVERSE TO GET OUT OF LOOSELY PACKED SNOW I FOUND I COULD NO LONGER GET THE CAR INTO A DRIVE GEAR ' FORWARD OR REVERSE. THE CAR HAD TO BE TOWED BECAUSE IT WAS NO LONGER OPERABLE AND WAS CAUSING A ROAD HAZARD FOR OTHER VEHICLES. THE DEALER CLAIMED SNOW CAUSED THE SHIFTING CABLE TO DETACH FROM THE GEAR SELECTOR. THE DEALER, HOLLY KIA, REPORTED THE PROBLEM WAS REPAIRED BY REATTACHING THE CABLE TO THE SELECTOR. MORE RECENTLY MY SON WAS OPERATING MY VEHICLE ON OR ABOUT JULY 6TH, 2010 ' A 100+ DEGREE DAY. HE REPORTED THAT HE WAS IN REVERSE TO MOVE THE CAR TO ANOTHER PARKING SPOT IN A CAR DEALERSHIP AND THE CAR COULD NO LONGER BE SHIFTED INTO ANY GEAR' AGAIN. DURING THIS INSTANCE THE CAR WAS ON A STEEP INCLINE AND MY SON WAS FORTUNATE TO BE ABLE TO MANEUVER THE CAR AROUND OTHER PARKED CARS BUT THE CAR HAD TO BE COASTED TO THE BOTTOM OF THE GRADE IN ORDER TO BE SAFELY PARKED. AFTER THE SECOND INSTANCE, THE CAR WAS AGAIN TOWED BACK TO HOLLY KIA FOR REPAIR - HOLLY KIA IS NOW REPLACING THE SHIFTING CABLE. THE HOLLY KIA SERVICE DEPARTMENT CLAIMS THIS PROBLEM WITH THE 2007 KIA OPTIMA AS A MANUFACTURING FLAW. MY CONCERN IS, AFTER THE REPAIR CAN THE CAR BE TRUSTED AND OPERATED SAFELY ' BOTH INCIDENTS LEFT THE CAR IN A VERY COMPROMISED STATE AND A HAZARD TO OTHER VEHICLES (MOVING AND PARKED). *TR
