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.

AFTER WARMING UP ENGINE I DROVE ONTO THE ROAD AND ONTO A FREEWAY ENTRANCE RAM A QUARTER MILE FROM MY HOME. WHILE ENTERING THE FREEWAY, THE CAR "LOST POWER", IE NO THROTTLE RESPONSE, CAR WOULD NOT GO FASTER THAN 60 MPH. RPM WAS PEAKING OVER 3,000 RPM (HIGHER THAN NORMAL). I PUT THE AUTO/MANUAL FLOOR-SHIFT INTO MANUAL AND THE DASH SHOWED 4TH GEAR. I SHIFTED BACK AND FORTH BETWEEN AUTO AND MANUAL WITH THE SAME RESULTS SEVERAL TIMES, 4TH GEAR, OVER 3,000 RPM, LOSS OF POWER (NO THROTTLE RESPONSE), MAX SPEED 60 MPH. I NEARLY GOT REAR ENDED, CARS WERE DODGING ME. I WAS ABOUT TO PULL OFF THE ROAD AND EVERYTHING RETURNED TO NORMAL. I READ A SIMILAR REPORT A FEW MONTHS AGO FROM ANOTHER "NEW" OWNER OF AN OPTIMA AND THE DEALERSHIP "COULDN'T FIND" ANYTHING WRONG. I NOW HAVE READ LOTS OF WARRANTY-DENIED HORROR STORIES WITH KIA. THIS SEEMS LIKE A TRANSMISSION PROBLEM. I IMAGINE IT COULD BE A "COMPUTER PROBLEM" AS THERE ARE LOTS OF COMPUTERS IN THESE NEW CARS. I CAN'T FIND ANY TSB'S LISTED FOR TRANSMISSION RELATED PROBLEMS, BUT AM WONDERING HOW MANY OTHERS HAVE THIS "ELUSIVE" CONDITION? *TR

WHILE DRIVING APPROXIMATELY 25MPH I HEARD A LOUD 'BANG'. SHORTLY THEREAFTER, MY OPTIMA WOULD PERIODICALLY SHIFT GEARS VERY ROUGHLY ON DOWNSHIFTS. THERE WAS ALSO A 'CLANKING' NOISE PRESENT ON THE ROUGH DOWNSHIFTS OR WHEN THE OPTIMA WAS SHIFTED INTO REVERSE. UPSHIFTS WHILE ACCELERATING SEEMED TO FUNCTION NORMALLY. I IMMEDIATELY BROUGHT THE CAR TO THE DEALERSHIP WHERE IT WAS PURCHASED. THE DEALERSHIP DETERMINED A BOLT HAD SNAPPED ON THE TRANSMISSION MOUNT CAUSING THE TRANSMISSION TO KNOCK INTO THE ENGINE WHEN IT SHIFTED. IT WAS THE BELIEF OF THE DEALERSHIP THAT THE BOLT HAD BEEN UNDER TORQUED WHEN IT WAS ASSEMBLED IN THE FACTORY. THE SUBFRAME AND A DENTED PIECE OF THE EXHAUST HAD TO BE REPLACED. THIS SEEMS VERY DANGEROUS TO ME, ESPECIALLY HAD IT OCCURRED ON AN EXPRESSWAY AT A HIGH RATE OF SPEED. *TR

WAS SITTING AT LIGHT AND WENT TO TAKE OFF CAR FELT LIKE IT DIDN'T WANT TO SHIFT INTO GEAR AND HAD A LOUD ROUGH GRINDING NOISE, ALL LIGHTS ON THE DASHBOARD CAME ONE. BRAKE LIGHT, CHECK ENGINE LIGHT, COOLANT, ETC AND NONE OF THE GAUGES WERE WORKING. I STOPPED AT THE STORE AND WENT TO LEAVE THE CAR WOULD START UP BUT WOULDN'T GO INTO GEAR, IT WAS STUCK IN PARK. I HAD TO GET IT TOWED TO THE DEALERSHIP TO HAVE IT LOOKED AT. I HAD JUST HAD THIS SAME PROBLEM 1 WEEK AGO WHERE ALL THE LIGHTS WERE ON AND THE GAUGES WEREN'T WORKING AND THE DEALERSHIP HAD SUPPOSEDLY REPLACED THE FUSE PANEL BOX BUT THAT APPARENTLY DIDN'T FIX THE PROBLEM. I THINK THAT IT'S A COMPUTER OR ENGINE ISSUE. *TR
