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. Kia's number for this recall is SC165.

Exterior lighting, brake lights, switchApr 1, 2013
Kia Motors Corporation (Kia) is recalling certain model year 2007-2010 Rondo, model year 2007-2011 Sedona, Sorento and Sportage, model year 2010-2011 Soul, model year 2008-2011 Optima, model year 2010 Forte, model year 2007-2009 Amanti, and model year 2009 Borrego vehicles. Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The total number of vehicles being recalled is now 980,377. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake-transmission shift interlock feature preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of PARK without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Kia will send an interim notification to owners in May 2013. When parts are available, owners will receive a second notification and dealers will replace the stop lamp switch, free of charge. Owners may contact Kia at 1-800-333-4542. Kia's recall campaign number is SC098.

TL* THE CONTACT OWNS A 2011 KIA OPTIMA. WHILE TRAVELING AT APPROXIMATELY 50 MPH AND ATTEMPTING TO SLOW DOWN FOR A STOP LIGHT, THE VEHICLE STALLED WITHOUT WARNING AND FAILED TO RESTART. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER WHO DIAGNOSED THAT THE STARTER BURNED OUT AND THAT THE ENGINE SEIZED. THE DEALER REPLACED THE STARTER AND WAS NOT ABLE TO DIAGNOSE THE SOURCE OF THE FAILURE. THE CONTACT WAS INFORMED THAT A MORE EXTENSIVE DIAGNOSIS WAS REQUIRED AND THE ENGINE NEEDED TO BE TAKEN APART. THE ENGINE FAILURE WAS NOT REPAIRED BY THE DEALER. THE VEHICLE WAS NOT ABLE TO BE DRIVEN. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE.

THIS KIA HAS A PUSH BUTTON START OPTION. THE VEHICLE WOULD NOT START AND THE BRAKE LIGHTS WERE NOT TURNING ON WHEN THE BRAKE PEDAL WAS DEPRESSED. THE COMPUTER LOOKS FOR A SIGNAL FROM THE BRAKE LIGHT SWITCH BEFORE IT STARTS THE ENGINE. I DISCONNECTED AND RECONNECTED THE BRAKE LIGHT SWITCH AND THE PROBLEM WAS TEMPORARILY CORRECTED. TWO DAYS LATER, THE VEHICLE WOULD NOT START AGAIN AND THE BRAKE LIGHTS WERE NOT TURNING ON. WE USED THE PROCEDURE TO BYPASS THE BRAKE SIGNAL (HOLD START BUTTON FOR 12+ SECONDS) TO START THE ENGINE. VEHICLE WAS NOW DRIVING DOWN THE ROAD WITH NO BRAKE LIGHTS. THERE WAS ALSO A WARNING LIGHT ILLUMINATED ON THE INSTRUMENT CLUSTER INDICATING AN ISSUE WITH THE ESC SYSTEM. DEALERSHIP STATED THEY HAVE SEEN A FEW CARS WITH THIS ISSUE. *TR

I WAS LEAVING WORK @ 5:45 PM AND GOT IN MY CAR, BUT IT WOULD NOT START. I TRIED FOR 20 MINUTES BEFORE I CALLED KIA LEDGEN DEALERSHIP FOR HELP. THEY TOLD ME WHERE TO PUT THE AUX KEY STARTER INSIDE THE GLOVE BOX AREA. AFTER SEVERAL ATTEMPTS THE CAR STILL WOULD NOT START. THEY TOLD ME A WOULD HAVE TO CALL THE 800 NUMBER TO GET A JUMP OR HAVE MY CAR TOWED. I FOUND A CO-WORKER WHO GAVE ME A JUMP AND THE CAR STARTED RIGHT UP. I PROCEEDED TO A FIRESTONE STATION AND GOT A NEW BATTER ($146.00). STARTED RIGHT UP AND HAD NO PROBLEMS UNTIL MY WIFE AND I WENT TO THE MALL TODAY (DEC 28) AND MY CAR WOULD NO START AGAIN. I THOUGHT WE WERE GOING TO GET STRANDED OR NEEDED TO FIND A JUMP. AFTER 5 ATTEMPTS IT FINALLY STARTED AND I TOOK MY CAR BACK TO THE DEALERSHIP AND THEY SAID THEY COULD NOT DUPLICATE THE PROBLEM SO THERE WAS NOTHING THEY COULD DO. AFTER STATING THAT I READ ABOUT OTHER KIA OWNERS HAVING THE SAME PROBLEM THEY DECIDED TO KEEP IT OVER NIGHT. ARE THERE OTHER OWNERS WITH SIMILAR PROBLEMS THAT CAN LEAD ME IN THE RIGHT DIRECTION TO GET THIS PROBLEM FIXED? *TR

THIS IS UPDATE TO ODI #10453907. OPTIMA HYBRID STILL EXPERIENCING POWER LOSS PROBLEMS.

THE FIRST EPISODE WAS A DEAD BATTERY. THE CAR HAD 13 MILES ON THE ODOMETER. THE SECOND INCIDENT, CAR WOULD NOT START, IGNITION ISSUE, BUT LATER STARTED (AFTER 1HR). TAKEN TO DEALER, SECONDARY TO IGNITION ISSUES. PROBLEM RESOLVED UNTIL TODAY. WOULD NOT START AGAIN. TRIED TWO DIFFERENT KEY FOBS AND STILL DID NOT START. THIS IS THE THIRD INCIDENT SINCE HAVING THE VEHICLE. I WILL NEED TO HAVE THE CAR TOWED FOR THE SECOND TIME. *TR

THE INTERIOR OVERHEAD LIGHTS PERIODICALLY COME ON AND GO OFF WHILE OPERATING OUR 2011 OPTIMA. THIS OCCURS WITH THE SWITCH IN BOTH ON AND OFF POSITION AND THE LIGHTBULBS TEND TO BECOME OVERHEATED.THEY DO NOT RESPOND TO MANUAL OPERATION, BUT GO OFF ON THEIR OWN AND THIS MALFUNCTION REPEATS SEVERAL TIMES IN A TEN MINUTE DRIVE. BEST-CASE SCENARIO RESULTS IN THE BULBS BURNING OUT PREMATURELY, BUT I BELIEVE THERE IS A REAL CHANCE OF A MORE SERIOUS SHORT-CIRCUIT AND POTENTIAL INTERIOR FIRE. *TR

THIS IS THE SECOND COMPLAIN REGARDING THE SAME ISSUE CAR FAIL TO START' THIS TIME THE CAR HAD TO BE TOWED TO, AND DROPPED AT THE KIA DEALER. AT THE END OF THE DAY WE CALLED THE DEALER TO SEE IF THEY HAD FOUND WHAT IS WRONG WITH IT. THE TECHNICIAN THAT WAS WORKING ON IT, MENTION THAT AS SOON AS THE CAR WAS UNCOUNTED FROM THE TOW TRUCK, THEY TRY AND SWITCH THE CAR; NEVERTHELESS, THE CAR STARTED WITHOUT ANY ISSUES. HE SAID THAT THEY SWITCH IT OFF AND ON THROUGHOUT THE DAY, AND WERE NOT ABLE TO REPLICATE THE PROBLEM. WHAT AM I TO DO? ALL I WANT IS FOR THE PROBLEM TO BE TAKEN CARE OF. I WANT TO DRIVE MY CAR WITHOUT THE FEAR OF BEING STRANDED. *TR

HAD JUST FINISH BRINGING MY WIFE HOME FROM THE HOSPITAL, AFTER SURGERY, AND NEEDED TO STOP AT THE PHARMACY. AFTER PICKING UP A COUPLE OF PRESCRIPTIONS WE GOT IN THE CAR, AND TRY TO SWITCH THE CAR ON, BUT IT WOULD NOT START. I COULD TELL THAT THE BATTERY HAD PLENTY OF POWER, BUT THE ENGINE WOULD NOT EVEN TURN. IT WAS ALMOST AS IF THE IGNITION WAS DISCONNECTED FROM THE REST OF THE CAR. I EVEN PUT IT ON NEUTRAL TO SEE IF I WOULD START, BUT NOTHING HAPPENED. I KEEP ON TRYING FOR ALMOST HALF HOUR, AND WHEN I WAS ABOUT TO CALL A TOW TRUCK I ATTEMPTED TO START IT AGAIN, AND IT FINALLY TURN AND STARTED. RIGHT NOW I HAVE A CAR WITH LESS THAN 20,000 THOUSAND MILES THAT I'M AFRAID TO DRIVE BECAUSE I'M AFRAID IT WILL LEAVE ME STRANDED. *TR

PURCHASED MY BRAND NEW KIA OPTIMA IN MAY 2011. FROM THE ONSET THE REMOTE START NEVER WORKED ON THE FIRST TRY, EVENTUALLY IT DIDN'T WORK AT ALL. IN AUG NOTICED THAT THE HORN WASN'T SOUNDING RIGHT, EVENTUALLY IT DIDN'T WORK AT ALL. I TOOK THE CAR IN FOR THE HORN TO BE REPAIRED AND THEY STATED THAT IT WAS A BAD FUSE. 1 WEEK LATER HORN WAS OUT AGAIN. I RETURNED TO THE DEALER WHO SAID THEY WOULD ORDER 2 NEW HORNS AS THEY WEREN'T SURE WHAT WAS THE CAUSE. BOUGHT THE CAR IN TO HAVE HORNS INSTALLED THEY SAY "WE NEED TO ORDER A NEW MODULE FOR YOUR CAR" ALTHOUGH THE HORNS WERE WORKING, I FIGURED THE MODULE WAS THE REASON THE HORNS WENT BAD IN THE FIRST PLACE. I CALL TO WEEKS LATER, THEY STILL HAVEN'T RECEIVED THE PARTS (STRANGE). I MENTION THAT NOW THE REMOTE START IS COMPLETELY OUT THEY SAY "WE KNOW, THAT IS WHY WE ORDERED THE MODULE" (WHY WASN'T THIS EXPLAINED TO ME??). OCT 2011 I SPEND YET ANOTHER SAT MORNING AT THE DEALER. AN HOUR AND A HALF IN THEY SAY WE CANT FIGURE THIS OUT WE NEED TO ORDER THE SCHEMATICS ON THIS CAR...YOU WILL NEED TO DROP THE CAR OFF NEXT WEEK. I LEAVE THE CAR FOR OVER A WEEK, THEY CALL TO SAY THEY ARE ORDERING A WHOLE NEW REMOTE START SYSTEM. WHEN I PICK UP THE CAR THE REMOTE START IS STILL WORKING INTERMITTENTLY, THE ALARM IS GOING OFF AT RANDOM AND THE SUNROOF WILL NOT CLOSE. I RETURN THE CAR THE FOLLOWING WEEK THEY SAY THEY ARE NOT HAVING ANY PROBLEMS WITH THE REMOTE START, ALARM HASN'T SOUNDED AND THEY JUST NEEDED TO REPLACE THE FUSE FOR THE ROOF. I AM NOT SURE WHAT THEY DID BUT THEY DID SOME SORT OF REPAIR, NO PROB WITH EITHER SINCE THEN. TODAY DEC 12, 2011 I HAVE CALLED TO TELL THEM THAT THE HORNS ARE COMPLETELY OUT AGAIN, "THEY SAY BRING HER IN AND WE WILL TAKE A LOOK AT HER". I HAVE NO DESIRE TO SPEND A DAY AT KIA DEALER ONCE A MONTH. IN FACT, I NO LONGER HAVE A DESIRE FOR KIA PERIOD. I AM CONTACTING BBB'S LEMON LAW ASSISTANCE TODAY. *TR

PURCHASE AS A NEW CAR ON JUNE 20,2011 FROM KIA DEALERSHIP. FIRST PROBLEM OCCURRED WITHIN FIRST MONTH. THE REMOTE START CONTINUALLY FAILED AT STARTING THE VEHICLE. WHEN PRESSING THE REMOTE START BUTTON THE CAR WOULD NOT START AND THE CAR ALARM WOULD SOUND OFF IMMEDIATELY. SECOND PROBLEM THAT OCCUR WITHIN FIRST MONTH IS THE GAS DOOR ON OUTSIDE WOULD NOT OPEN WHEN PRESSING THE GAS BUTTON ON THE INSIDE OF THE CAR. IT REQUIRED YOU TO KEEP PRESSING GAS BUTTON REPEATEDLY BEFORE IT WOULD OPEN THE OUTSIDE DOOR TO PUMP GAS. THIRD PROBLEM THAT OCCURRED WITHIN THE THIRD TO THE FOURTH MONTH OF THE PURCHASED VEHICLE IS THE SOUND TO THE CAR HORN FAILED. WHEN I WENT TO BLOW MY HORN, THERE WAS NO SOUND WHICH ALSO LEAD TO NO SOUND ON THE CAR TO INDICATE THAT I HAD LOCKED THE VEHICLE WITH THE REMOTE CAR-LOCK. THE LOST SOUND TO THE HORN AND TO THE VEHICLE HAS RECENTLY FAILED FOR A SECOND TIME AFTER RECENTLY BEING REPAIRED BY THE DEALERSHIP. *TR

DEFECTIVE KEY FOBS. THEY CANNOT BE REPROGRAMMED AND YOU BECOME STRANDED WITH NO WAY OF STARTING THE AUTO. DEALERSHIP HAS TRIED FOUR TIMES TO REPROGRAM THE KEY FOB WITHOUT SUCCESS. THERE IS NO WAY TO START OR OPERATE THE CAR WITH THE MECHANICAL KEY. CAN BECOME A DANGEROUS SITUATION IF YOU ARE IN AN ISOLATED AREA! *TT
