WHEN SHIFTING MY 2009 KIA SORENTO FROM P TO R, IT VIOLENTLY JOLTS INTO R AND THEN WHEN SHIFTING INTO D, IT HAS ALMOST NO POWER, AS IF I WERE DRIVING IN FIRST GEAR WITH A MANUAL TRANSMISSION (VEHICLE IS AUTOMATIC). AFTER A FEW MINUTES, IT WILL DRIVE NORMALLY UNTIL I STOP, THEN IT AGAIN IS VERY SLUGGISH WITH ALMOST NO POWER UNTIL IT "CATCHES". SOMETIMES IF I STOP THE CAR, PUT IT IN PARK AND SHUT IT OFF, THEN RESTART, IT WORKS FINE. THIS PROBLEM DOES NOT HAPPEN EVERY DAY, IT'S RANDOM BUT WHEN IT HAPPENS, IT IS VERY SCARY AND I AM NOW AFRAID OF DRIVING IT. EVERY TIME I START THE CAR, I GINGERLY SHIFT TO D OR R, WAITING FOR THE JOLT. I AM AFRAID IT'S GOING TO JERK BACKWARDS OUT OF CONTROL AND HIT SOMEONE/SOMETHING. IT HAS BEEN HAPPENING FOR TWO YEARS NOW, OFF AND ON. DEALER SAID THEY CAN'T DUPLICATE THE PROBLEM AND "THERE IS NOTHING THEY CAN DO UNTIL IT BREAKS". IN WHICH CASE MY WARRANTY WILL BE OVER AND THEY'LL CHARGE ME FOR A NEW TRANSMISSION. CALLED KIA AND THEY TOLD ME THE SAME THING BUT THEY OPENED A TICKET FOR MY PROBLEM. I KNOW BOTH KIA AND THE DEALERSHIP KNOWS WHAT THE PROBLEM IS BUT THEY ARE IGNORING IT. I HAVE DONE A LOT OF INTERNET RESEARCH REGARDING THIS PROBLEM AND SEE COMPLAINT AFTER COMPLAINT (INCLUDING THREE ON THIS SITE JUST FOR THE 2009 MODEL ALONE). I KNOW THE 2011 MODELS HAD SIMILAR PROBLEMS ALSO. IT'S VERY SAD BECAUSE I REALLY LIKE THE CAR BUT I'M TOO NERVOUS DRIVING IT NOW SO I'LL BE TRADING IT IN AND GOING BACK TO A CHEVY. *TR

RECENTLY BROUGHT MY 2009 KIA SORENTO TO THE DEALER ON 9/9/13. THE VEHICLE WAS BANGING INTO GEAR (WHETHER REVERSE OR DRIVE) AND IT WAS SLUGGISH WHEN ATTEMPTING TO DRIVE. IT WAS VERY SCARY TRYING TO MAKE A LEFT TURN WHILE CROSSING OVER ONCOMING TRAFFIC AS THE CAR WAS NOT GOING ANYWHERE WHEN TRYING TO DRIVE. THE CHECK ENGINE LIGHT ALSO CAME ON. MY CHECK ENGINE LIGHT SOMEHOW WAS NOT ON WHEN THEY TOOK POSSESSION OF THE VEHICLE.THE DEALERSHIP TOLD ME THEY COULDN'T DUPLICATE THE PROBLEM. THEN SENT ME ON MY WAY WITH NO RECOMMENDATIONS. NOW A WEEK LATER, 9/17/13, I CALLED THE DEALER AND REPORTED THE SAME INCIDENT AS BEFORE. THEY TOLD ME TO DRIVE IT TO THEM AND KEEP THE CAR RUNNING. THE CHECK ENGINE LIGHT WAS ON AGAIN. AS THE TECH AT THE DEALER TOOK POSSESSION OF MY VEHICLE, YOU CAN HEAR IT BANG INTO GEAR AND HEAR THE RPM'S RACING AS THEY DROVE FORWARD. THE TECH ADVISED THAT THE CHECK ENGINE CODES WERE STORED HISTORY CODES. THEY ARE TO DO WITH THE TRANSMISSION. THIS TIME KIA ADVISES TO REPLACE THE TRANSMISSION. MEANWHILE, THE TRANSMISSION WAS REPLACED DECEMBER OF 2011. KIA STILL HAS MY TRUCK AS I AM AFRAID TO DRIVE IT. I HAVE A CALL INTO KIA CUSTOMER SERVICE REGIONAL OFFICE. THIS HAS BEEN AN ONGOING PROBLEM FROM EARLY ON. I HAD BROUGHT THE VEHICLE IN ON NUMEROUS OCCASIONS AND THE DEALERSHIP WOULD TELL ME THEY COULDN'T DUPLICATE MY PROBLEM. THIS IS A SAFETY ISSUE! WHEN YOU PUT THE CAR INTO GEAR, THERE IS A LOUD BANGING SOUND (SOUNDS LIKE YOU WERE REAR ENDED). THEN WHEN YOU APPLY THE GAS PEDAL TO GO FORWARD, THE CAR GOES NOWHERE. THE RPMS RACE AND YOU ARE BARELY MOVING. AT OTHER TIMES, WHEN YOU SLOW DOWN IN TRAFFIC OR ARE STOPPED AT A LIGHT, AND ATTEMPT TO DRIVE, YOU BARELY MOVE AS THE RPM'S ARE RACING. THIS PROBLEM NEEDS TO BE ADDRESSED! IT IS A SAFETY ISSUE!! *JS

'PASSENGER AIR BAG OFF' LIGHT ON REPEATEDLY WITH A PASSENGER IN SEAT AND AFTER TURNING ENGINE OFF AND ON AND RE-POSITIONING OF PASSENGER MORE THAN 1 DOZEN TIMES! THIS VEHICLE WAS PURCHASED USED AS A REPLACEMENT VEHICLE, AFTER SURVIVING BEING HIT HEAD-ON, SEVERELY INJURED AND OUR VEHICLE DESTROYED. AIR BAGS HELPED SAVE OUR LIVES. THE SORENTO HAS HAD THIS PROBLEM SINCE DATE OF PURCHASE IN FEBRUARY 2010. WE HAVE REPEATEDLY TALKED TO KIA HEADQUARTERS AND DEALERSHIPS REGARDING THIS PROBLEM. NORMAL PASSENGER IS MUCH HEAVIER THAN 120 LB "GRAY AREA" NOTED TO AFFECT ACTIVATION. ONE DEALERSHIP PRINTED A READOUT "PROVING" USUAL PASSENGER "SITS LIGHT" - ADVISED ADJUSTING SITTING POSITION. YESTERDAY TEMPS IN AZ EXCEEDED 110 DEGREES AND THE PROBLEM WAS SEVERE. THE LIGHT CAME ON WHEN VEHICLE WAS STARTED, WOULD GO OFF AND COME BACK ON AS SOON AS THE SHIFTING LEVER WAS MOVED. THE PASSENGER LIFTED AND READJUSTED EACH TIME TO NO AVAIL. THIS PROCESS WAS REPEATED EACH TIME THE VEHICLE WAS STARTED. OFTEN THE LIGHT COMES ON WHEN SHIFTING INTO REVERSE TO EXIT DRIVEWAY OR PARKING PLACE, WITH NO MOVEMENT FROM PASSENGER. THIS IS A SERIOUS SAFETY HAZARD!! MUST SOMEONE DIE BEFORE KIA CORRECTS THIS PROBLEM?!?! (AIR BAG SHOULD ALWAYS BE ACTIVATED!!!!!) KIA SHOULD BE MANDATED TO FIX THIS LIFE THREATENING PROBLEM BEFORE FATALITIES OCCUR!!!!!!!! CORRECTION OF THIS PROBLEM IS SURELY LESS EXPENSIVE THAN LAWSUITS FOR INJURIES/DEATHS CAUSED BY INACTIVE AIR BAGS! *TR

I WAS DRIVING ALONG A STATE HIGHWAY WHEN MY CAR SUDDENLY LOST POWER. "ESC OFF" LITE UP ON THE DASH AS DID AN ANTI LOCK BRAKE LIGHT. I WAS ABLE TO COAST TO A SAFE PLACE ON THE SIDE OF THE ROAD. I SHUT THE CAR OFF AND TRIED TO RESTART IT TWICE WITH NO RETURN OF THE POWER. THE ENGINE WOULD RUN BUT DID NOT RESPOND TO THE ACCELERATOR. I SHUT THE CAR OFF AND CALLED FOR A TOW. WHEN THEY ARRIVED 45 MINS LATER HE STARTED THE CAR AND IT WORKED FINE EXCEPT THE ENGINE LIGHT WAS ON. I WAS THEN ABLE TO DRIVE THE CAR HOME. I HAD A MECHANIC CHECK THE CAR AND WAS TOLD ALL HE COULD FIND WAS A CODE THAT INDICATED THERE HAD BEEN SOME PROBLEM WITH THE ESC AND THAT THAT PROBLEM HAD SHUT THE GAS OFF TO THE ENGINE. HE RESET THE SYSTEM AND EVERYTHING SEEMED FINE FOR 5 DAYS OR ABOUT 260 MILES. THEN IT OCCURRED AGAIN IN A SITUATION OF INCREASED TRAFFIC. I WAS AGAIN ABLE TO SAFELY GET OFF THE ROAD AND AFTER WAITING ABOUT 10 MINS WAS ABLE TO RESTART THE CAR AND DRIVE HOME. I AM VERY CONCERNED THAT IF THIS OCCURRED AT A HIGHER SPEED I WOULD END UP IN AN ACCIDENT. I HAVE AN APPOINTMENT WITH THE KIA DEALER NEXT WEEK, BUT WILL BE DRIVING ON THE INTERSTATE TO GET MY CAR TO THEM. IT APPEARS THERE HAVE BEEN OTHERS WITH THE SAME PROBLEM. PLEASE ADVISE ME IF YOU ARE INVESTIGATING THIS PROBLEM. *TR

WHEN MERGING ONTO THE INTERSTATE (INCREASING SPEED FROM 25MPH AND UP) VEHICLE SUDDENLY STOPS AND DOESN'T ALLOW ME TO ACCELERATE AND THE ESC OFF ILLUMINATES ON THE DASH AS WELL AS THE CHECK ENGINE LIGHT. IN ORDER TO OPERATE THE VEHICLE I HAVE TO MOVE OFF OF THE HWY INTO THE EMERGENCY LANE, PUT ON MY FLASHERS, TURN OFF THE VEHICLE, RESTART THE VEHICLE, AND PRESS THE ESC OFF BUTTON. THE VEHICLE THEN STARTS AND I SLOWLY MERGE BACK ONTO THE HWY CAUTIOUS NOT TO ACCELERATE TOO QUICKLY AS THE ENTIRE PROCESS WOULD OCCUR AGAIN. THIS IS EXTREMELY DANGEROUS AS IT OCCURS WHEN AN INCREASE IN SPEED IS NEEDED AND IT NEEDS TO BE ADDRESSED. I HAVE TAKEN MY VEHICLE IN TO THE KIA DEALERSHIP, THEY 'TIGHTENED SOME WIRES" AND LITERALLY THE NEXT DAY IT OCCURRED AGAIN. *TR

UPON STARTING THE 2009 KIA SORRENTO ONE DAY, I SHIFTED TO REVERSE AND NOTICED A VIOLENT JERK WITH A LOUD POPPING SOUND. UPON PUTTING IT INTO DRIVE, THE CAR WOULD BARELY ACCELERATE BUT THE ENGINE WOULD STILL REV WHEN PRESSING DOWN ON THE GAS PEDAL. THE CHECK ENGINE LIGHT WAS ON BUT LATER WENT AWAY. THE DEALERSHIP HAS SEEN THE CAR MULTIPLE TIMES AND OUR SERVICE ADVISOR GARY DAWSON IN HOUSTON, TX SAYS THEY CANNOT REPRODUCE THE PROBLEM OR FIND ANY FAULT CODES (EVEN THOUGH WE PROVIDED THE CODE PULLED FROM AUTOZONE THE PREVIOUS DAY). CODES SAID THE TRANSAXLE AND HIGH/LOW SOLENOID WERE THE PROBLEMS. THE CAR IS IN THEIR POSSESSION NOW BUT AFTER A QUICK TALK WITH OUR SERVICE ADVISOR I HIGHLY DOUBT THEY WILL BE FIXING ANYTHING. A QUICK GOOGLE SEARCH SHOWS ALMOST ALL 2005+ SORRENTOS HAVE TRANSMISSION PROBLEMS. PLEASE DO SOMETHING ABOUT KIA AND KEEP THEM IN CHECK. *JS

WHILE DECENDING A MOUNTIAN PASS IN COLORADO WITH THE VEHICLE IN 4WD-LOW RANGE AND THE SHIFT SELECTOR IN THE SPORT MODE THE TRANSMISSION WOULD UP-SHIFT AT ABOUT 3200 RPM CAUSING THE VEHICLE TO GAIN SPEED VERY QUICKLY AND REQUIRING THE CONSTANT APPLICATION OF BRAKES WHICH CAUSES THE BRAKES TO OVER HEAT. THE OWNERS MANUAL CLEARLY STATES THAT THIS IS AN APPROVED USE OF THE VEHICLE AND THAT THE TRANSMISSION SHOULD NOT SHIFT UNTIL THE RED-ZONE (APPROX 6000 RPM). I CONTACTED KIA CUSTOMER SERVICE IN NOVEMBER OF 2009 AND HAVE HAD SEVERAL CONVERSATIONS WITH KIA'S CUSTOMER SERVICE AND MR RICHARD PULRIDIA WHITH KIA SERVICE HAS EVALUATED THE VEHICLE AND FILED A REPORT WITH KIA ENGINEERING IN MAY 2011. I TALKED TO MR PULRIDA THIS WEEK AND HE HAS NOT RECEIVED ANY INFORMATION TO DATE AND HAS NO IDEA WHEN OR IF ANY ACTION WILL BE TAKEN TO CORRECT THIS UNSAFE CONDITION. I BELIEVE THIS OPERATION IS UNSAVE BECAUSE IT CAUSES QUICK ACCELLERATION TO UNSAFE SPEEDS WHIN IN A STEEP DECENT. *TR

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.
Consequence & remedy
Consequence: 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.
Remedy: 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.

Opened Nov 12, 2021 · Closed Jun 20, 2023
Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
