Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.
If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542.

MY WIFE WAS DRIVING ON THE FREEWAY AT 6:20 P.M IN THE SLOW LANE AT 65 MPH WHEN SHE HEARD A LOUD EXPLOSION AND THE SUNROOF SHATTERED. THERE WERE NO VEHICLES IN FRONT OF HER OR AROUND HER THAT COULD POSSIBLY HAVE KICKED UP A ROCK OR DEBRIS FROM THE ROAD. SHE WAS ALSO NOT PASSING UNDER AN OVERPASS OR BRIDGE. LUCKILY, SHE WAS ABLE TO CONTROL THE CAR AND WAS NOT PHYSICALLY HURT IN THE INCIDENT. THIS VEHICLE HAS A PANORAMIC SUNROOF AND THE MOVING PART OF THE GLASS SUNROOF SHATTERED.

Electronic stability control (ESC), Feb 13, 2018
MY ELECTRONIC STABILITY CONTROL LIGHT ON DASH CAME ON AND REMAINS ON. I TOOK TO MARTIN KIA IN NEWARK DELAWARE FOR DIAGNOSTIC AND THEY SAID THE CODES WERE C1259 AND C1260 AND THAT I NEED TO HAVE CLOCK SPRING ASSEMBLY, STEERING ANGLE SENSOR AND THE STEERING COLUMN ASSEMBLY REPLACED BECAUSE IT LOOKED LIKE MY CAR HAD BEEN IN AN ACCIDENT. (I DID STRIKE A SMALL DEER, BUT DAMAGE WAS COSMETIC TO LEFT FRONT FENDER AND DID NOT AFFECT STEERING OR DRIVABILITY, AND WAS REPAIRED IN A PROFESSIONAL BODY SHOP). THE ESC DID NOT COME ON UNTIL MONTHS AFTER MY ACCIDENT. DEALER WOULD NOT CERTIFY THAT THE VEHICLE IS SAFE TO DRIVE WITH THIS CONDITION, NOR DID THEY OFFER ANOTHER LESS EXPENSIVE REPAIR SUCH AS JUST REPLACING SENSORS. THEY WANTED AN ESTIMATED $1370 TO HOLD MY SAFETY HOSTAGE. SINCE THE LIGHT HAS BEEN ON, I HAVE EXPERIENCED A FEW EPISODES OF INSTABILITY WHEN DRIVING IN INCLEMENT WEATHER. I NOW LEAVE ESC OFF WHEN WEATHER IS BAD.

TURBO AND TURBO OIL RETURN LINE IS DEFECTIVE. LEAKS OIL AND OVER HEATS ENGINE. DEALERSHIPS ADMIT THIS IS A SERIOUS ISSUES THAT THEY'VE SEEN DAILY WITH THE SX MODELS BUT REFUSE TO ADDRESS IT UNTIL A RECALL COMES OUT. ANYTIME THE VEHICLE IS DRIVEN, IT CONSTANTLY LEAKS OIL. WHENEVER IT IS PARKED, IT LEAKS OIL. IT'S ONLY FROM THE TURBO FEED LINE.

AT HIGHWAY SPEEDS, INTERMITTENTLY , THE STEERING WILL GET STUCK IN THE 12 O'CLOCK POSITION FOR APPROXIMATELY 1 SECOND, REPEATABLY HAPPENS ONCE IT STARTS HAPPENING, UNTIL OFF HIGHWAY. STEERING CAN BE FINE FOR MONTHS, AND THEN ISSUE CAN COME BACK. THEN WHEN DEALER INSPECTS IT, ISSUE IS GONE. THIS IS A VERY UNSAFE AND SERIOUS ISSUE, EVEN A SPLIT SECOND OF REDUCED RESPONSE TIME CAN MEAN THE DIFFERENCE BETWEEN LIFE AND DEATH. DEALER SAID THEY PERFORMED THE STEERING LOGIC IMPROVEMENT UPDATE, BUT ISSUE STILL HAPPENS ON OCCASION.

I FIRST NOTICED A PROBLEM WITH MY VEHICLE WHEN THE CRUISE CONTROL WOULD RANDOMLY DISENGAGE WHILE GOING DOWN THE INTERSTATE. THEN A COUPLE OF WEEKS LATER I WAS MAKING A LEFT TURN ACROSS A TWO LANES OF TRAFFIC ON A CITY STREET. WHEN I FIRST PUSHED THE ACCELERATOR THE CAR STARTED TO GO AND THEN SUDDENLY I LOST ALL ACCELERATION. I LET MY FOOT OFF THE ACCELERATOR AND THEN PUSHED BACK DOWN AND WAS ABLE TO GO. THIS WAS A VERY DANGEROUS SITUATION AS I WAS STUCK IN THE MIDDLE OF TWO LANES OF TRAFFIC FOR SEVERAL EXTRA SECONDS LONGER THAN NECESSARY. A SIMILAR SITUATION HAPPENED A COUPLE OF MORE TIME AND WHEN I PARKED THE VEHICLE AT HOME I NOTICED THAT BRAKE LIGHT WAS STAYING ON AFTER I GOT OUT OF THE CAR. I TOOK THE CAR TO THE LOCAL KIA DEALERSHIP AND THEY REPLACED THE BRAKE SENSOR WHICH FIXED ALL OF THE ABOVE PROBLEMS. I WOULD LIKE TO NOT THAT HYUNDAI ISSUED A RECALL ON THE NEARLY IDENTICAL SONATA FOR THIS SAME ISSUE AND DID SO YEARS AGO AND YET NOTHING FOR THE OPTIMA.
