2009 KIA OPTIMA Power Train Problems

WHILE DRIVING THE CAR WHEN COLD THE CAR DOWNSHIFTS HARD INTO FIRST AT ABOUT 20 MPH. ALMOST AT SOMETIMES FEELING LIKE I HAVE BEEN HIT FROM THE BACK. MY NECK HAS STARTED HURTING FROM WHIPLASH. THIS IS A VERY HORRIBLE PROBLEM THAT NEEDS TO BE FIXED. IN STATES WHERE ROADS BECOME WET, ICY, AND COVERED WITH SNOW, THIS CAN CAUSE A LOT OF DAMAGE/ POSSIBLY DEATH.

WHEN CAR IS SLOWING DOWN AND /OR APPROACHING A STOP SIGN IT GIVES A HARD JERK. EVEN IF TRAFFIC SLOWS DOWN ON THE EXPRESS WAY IT GIVES A HARD JERK. THIS HAS BEEN GOING ON SINCE NOVEMBER 2020.

Mileage: 102,000

DRIVING AT 70 MPH, ENGINE DIED AND CAR STARTED SMOKING. PULLED TO SHOULDER, FRONT END OF CAR CAUGHT FIRE. FIRE DEPARTMENT EXTINGUISHED WITH FOAM. CAR A TOTAL LOSS.

Mileage: 140,000

CAR LURCHES AT 20 MPH WHEN SLOWING DOWN TO A STOP. THIS HAPPENS AFTER JUST STARTING THE CAR, ONCE DRIVEN ON THE HIGHWAY IT DOWNSHIFTS WITHOUT LURCHING FORWARD. THIS HAPPENED YEARS AGO AROUND 70,000 DEALER FLUSHED TRANSMISSION AND IT WAS OK UNTIL NOW AT 120,000. SEEMS LIKE THIS IS A COMMON REOCCURRING PROBLEM THAT SHOULD BE RECALLED.

MY 2009 KIA OPTIMA WITH 90,000 MILES IS EXPERIENCING A HARD DOWNSHIFT INTO FIRST GEAR WHEN IT DECELERATES TO ABOUT 20 MPH. IT IS SO ABRUPT, IT FEELS AS IF THE BRAKES HAVE BEEN APPLIED VERY RAPIDLY. THE CAR JERKS FORWARD AND IS ACCOMPANIED BY A CLUNKING SOUND FROM THE TRANSMISSION. IT MOSTLY HAPPENS WHEN THE VEHICLE IS COLD AND GOES AWAY AFTER IT HAS WARMED UP. IT JUST STARTED AND I HAVE NOT TAKEN IT TO BE SERVICED.

Mileage: 90,000

TRANSMISSION SHIFTING HARD - STARTED AROUND 60,000 MILES. SHIFTS HARD FROM SECOND GEAR TO FIRST GEAR - AROUND 20 MPH. TOOK IT IN TO HAVE THE SYSTEM (COMPUTER) UPGRADE IN JANUARY OF 2014 ($500) -- THIS FIXED THE ISSUE FOR ABOUT 6 MONTHS. TOOK IT BACK IN JANUARY OF 2015 ($500) FOR ANOTHER SYSTEM (COMPUTER) UPGRADE. IT FIXED THE ISSUE FOR SEVERAL MONTHS. TOOK IT BACK TO KIA AND THE DEALERSHIP RECOMMENDED A NEW TRANSMISSION. I ASKED THE TECH IF HE COULD GUARANTEE ME THAT THIS WOULD STOP THE ISSUE. HE TOLD ME HE COULD NOT GUARANTEE ME THAT INSTALLING A NEW TRANSMISSION WOULD STOP THE HARD DOWNSHIFTING ISSUE. IT DOWNSHIFTS SO HARD THAT YOU FEEL LIKE SOMEONE HAS SLAMMED ON THE BRAKES.

LATE LAST YEAR (2014) IN OUR KIA OPTIMA 2009 GOT SOME TRANSMISSION ISSUE WHICH IS DIFFICULT TO EXPLAIN FOR. TO ME IT LOOKS LIKE A MANUFACTURING DEFECT WHICH KIA MUST RESOLVE. THIS IS WHAT I EXPERIENCED: IN 2014 OCTOBER, I STARTED FEELING A HEAVY JOLT/JERK WHENEVER I USED THE CAR AND THE ENGINE IS COLD. THE JOLT IS SO STRONG THAT EVERY PASSENGER NOTICED IT. THIS HAPPENS ONLY WHEN I TRY TO SLOW DOWN THE CAR AND IT GETS NEAR TO 20 MPHR. SO THE FACTORS ARE: 1. COLD 2. DOWNSHIFT 3. SPEED 20 MPHR ON SLIPPERY ROADS IT MAY BE VERY DANGEROUS WHICH CAN LEAD TO MAJOR INJURIES. KIA MUST ACCEPT THIS DANGEROUS MANUFACTURING DEFECT BEFORE IT START TAKING LIVES. IT IS VERY ANNOYING ISSUE TOO, IT IS ALWAYS ON MY MIND WHILE DRIVING WHICH IS CAUSING DISTRACTION WHILE DRIVING. KIA MUST TAKE AN ACTION INSTEAD OF SITTING QUITE. THEY MUST ISSUE RECALL THIS TO FIX THIS DANGEROUS ISSUE. NHTSA ALSO SHOULD SUPPORT ALL THE PEOPLE WITH SAME PROBLEM SO THAT PEOPLE CAN BELIEVE THEIR SAFETY STANDARDS. I TOOK MY CAR 2-3 TIMES THERE AND EXPLAINED THE ISSUE, BUT THEY COULD NOT FIX IT SO FAR. IF KIA'S OWN DEALERS CANNOT FIX THIS PROBLEM THEN WHO WILL? THANKS FOR READING MY COMPLAINT AGAINST KIA! *TR

Mileage: 50,000

WHILE SLOWING DOWN AND BREAKING THE TRANSMISSION MAKES A ROUGH DOWNSHIFT AROUND 20 MPH. IT WILL LITERALLY JOLT THE DIVER AND PASSENGERS. THE TRANSMISSION WILL DO THIS UNTIL IT HAS WARMED UP. IT IS ESPECIALLY BAD DURING THE COLD WINTER MONTHS. THE DEALER HAS LOOKED AT IT THREE DIFFERENT TIMES AND MADE ONE ADJUSTMENT TO THE TRANSMISSION SOFTWARE BUT TO NO AVAIL. I STOPPED BY THE DEALER AGAIN YESTERDAY AND THEY SAID I WOULD BE CHARGED A $105 FEE JUST TO LOOK AT IT. I AM AFRAID THE TRANSMISSION IS GOING TO LOCK-UP AND CAUSE A WRECK. *TR

I AM NOT THE ONLY ONE WHO HAS HAD THIS ISSUE WITH KIA OPTIMAS ...PLEASE DO A RECALL ON THIS MATTER ...IT IS GETTING OUT OF HAND ..THANKS [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

WHEN THE VEHICLE SLOWS TO 20 MILES PER HOUR, THE CAR DOWNSHIFTS HARD BY ITSELF. CAR LURCHES FORWARD. IN RESEARCHING ONLINE, I FOUND NUMEROUS REPORTS OF THE SAME THING. FIRST THOUGHT IT WAS THE BRAKES, BUT MECHANIC SAID BRAKES WERE FINE. IT CAN ONLY BE THE TRANSMISSION / POWER TRAIN. *TR

WHEN THE VEHICLE SLOWS TO 20 MILES PER HOUR, THE CAR DOWNSHIFTS HARD BY ITSELF. IN RESEARCHING ONLINE, I FOUND NUMEROUS REPORTS OF THE SAME THING. IN SPEAKING WITH MY PERSONAL MECHANIC, HE SAID THIS SHOULD BE COVERED UNDER THE TRANSMISSION PORTION OF THE POWER TRAIN WARRANTY - NEW TRANSMISSION SOFTWARE NEEDS TO BE RE-DOWNLOADED TO THE CAR'S COMPUTER AND THEN THE COMPUTER RESET - THIS SHOULD RETRAIN THE TRANSMISSION ON WHEN TO DOWNSHIFT. *TR

I PURCHASED A USED KIA OPTIMA IN MARCH 2012, BUT HAD, WHAT I THOUGHT WERE "GRABBING" BRAKES. I TOOK IT IN WHEN I FOUND A SERVICE BULLETIN TSB-067. I HAD THE CAR ANALYZED, AND FOUND IT HAD THIS SHIFTING ISSUE. I HAD THE REPROGRAMMING DONE AND EVERYTHING WAS FINE FOR A LITTLE OVER A YEAR, THEN NOT ONLY DID THE DOWNSHIFTING ISSUE START BACK UP AGAIN, BUT NOW HAVE ACCELERATION ISSUES AS WELL. NOW THE VEHICLE "LOPES" ON ACCELERATION - SOMETIMES A LOT . I CONTACTED KIA ABOUT IT, AND THEY SAID I HAD TO TAKE IT BACK FOR DIAGNOSIS YET AGAIN, AND THEN THEY WOULD THINK ABOUT REIMBURSEMENT FOR THE SECOND SERVICE APPOINTMENT. I DO NOT UNDERSTAND WHY THERE IS NOT A RECALL ON IT YET. IT IS DESTROYING MY TRANSMISSION BECAUSE OF THE "BANGING" OF THE TRANSMISSION DUE TO THE EXTREME DOWNSHIFTING OF THE VEHICLE. *TR

Mileage: 62,000

WHILE LEAVING FOR WORK IN THE AM, AS I DECELERATE AT THE STOP SIGN, WHEN SPEED NEARS 20-25 MPH THE VEHICLE JERKS HARD LIKE IT'S TRYING TO DOWNSHIFT. SEEMS TO DISAPPEAR AS THE VEHICLE WARMS TO RUNNING TEMP. *TR

Mileage: 54,835

WHEN I BRAKE AND SLOW DOWN MY KIA OPTIMA AND IT GETS TO 20 MPH OR LOWER, IT WILL JERK SUDDENLY AS IF THE TRANSMISSION IS CHANGING ABRUPTLY AND DANGEROUSLY. THIS HAS BEEN AN ONGOING ISSUE AND NOT JUST A RECENT OCCURRENCE. *TR

VEHICLE AIR BAG TROUBLE LIGHT ILLUMINATED ON DASHBOARD. WHEN BROUGHT TO THE DEALER, WE WERE TOLD THAT A SEAT SENSOR WAS DEFECTIVE AND NEEDED REPLACEMENT AT A COST OF $1500. THIS IS ON TOP OF A RECENT $2700 TRANSMISSION REPLACEMENT ON THE SAME VEHICLE ONE MONTH PRIOR. SINCE WE ARE STILL PAYING FOR THE TRANSMISSION REPAIR, WE CHOSE TO DRIVE THE VEHICLE WITHOUT THE AIR BAG SYSTEM FUNCTIONING PROPERLY WHICH WE REALIZE IS A SAFETY ISSUE, BUT WE CANNOT AFFORD ANOTHER EXPENSIVE KIA REPAIR. *TR

Mileage: 65,000

THE VEHICLE HAD THREE EXPENSIVE PROBLEMS IN RAPID SUCCESSION. THE FIRST WAS THE TRANSMISSION WHICH STARTED A SEVERELY HARD DOWNSHIFT ON BRAKING FROM ABOUT 25 MPH. THE WHOLE CAR SHUDDERED AND FELT AS IF WE SLAMMED ON THE BRAKES FOR A SECOND. AFTER TROUBLESHOOTING, KIA TOLD US WE NEEDED A NEW TRANSMISSION FOR $2700 WITH NO HELP FROM KIA. AFTER THIS REPAIR, NOT EVEN TWO WEEKS LATER, THE AIR BAG LIGHT CAME ON. DIAGNOSIS FROM KIA, DEFECTIVE SENSOR IN THE PASSENGER SEAT, NOT COVERED BY WARRANTY AND A $1500 REPLACEMENT ESTIMATE. WE DECIDED NOT TO FIX THIS ITEM BECAUSE WE WERE GOING TO TRADE THE CAR IN ON ANOTHER MAKE AND CUT OUR LOSSES. THE THIRD PROBLEM WHICH OCCURRED ONE WEEK LATER WAS A FAILURE TO START AFTER PARKING THE CAR FOR AN HOUR AT A DOCTOR'S OFFICE, STRANDING MY WIFE IN 95 DEGREE HEAT. THE CAR WAS TOWED TO A NON-KIA REPAIR SHOP AS I NO LONGER WANT ANYTHING TO DO WITH KIA WHO WILL DENY ANY CLAIM AGAINST THEIR SO-CALLED QUALITY PRODUCTS AND WILL BE DISPOSING OF THE CAR AS SOON AS IT IS RUNNING AGAIN SINCE KIA DOES NOT STAND BEHIND ITS DEFECTIVE PRODUCTS. AFTER THREE MAJOR FAILURES IN A SHORT PERIOD OF TIME WE FEEL THIS IS AN UNSAFE VEHICLE. *TR

IN THE PAST MONTH I HAVE NOTICED WHEN COMING TO A STOP AND APPLYING THE BRAKES ON MY 2009 KIA OPTIMA THAT THE CAR JERKS LIKE IT DOESN'T WANT TO STOP. I HAVE HAD MY BRAKE PADS CHECKED AND THEY ARE FINE. I HAVE HOWEVER NOTICED THAT WHEN I'M COMING TO A STOP AND PUT THE CAR IN NEUTRAL I STOP FINE WITH NO JERKING. I HAVE TAKEN IT TO A TRANSMISSION SHOP AND THEY HAVE SAID THAT THEIR IS NO PROBLEMS THERE AND HAVE ALSO CALLED THE LOCAL KIA DEALERSHIP TO HAVE THE PROBLEM LOOKED AT BUT THEY STATED THAT IF ITS SOMETHING NOT COVERED UNDER WARRANTY I HAVE TO PAY $100 JUST FOR THEM LOOKING AT THE VEHICLE REGARDLESS IF THEY FIND THE PROBLEM OR NOT. I HAVE SEARCHED THE INTERNET AND HAVE SEEN SIMILAR PROBLEMS WITH THIS PARTICULAR CAR BUT NO INFORMATION ON WHAT IS CAUSING THE ISSUE. *TR

TL* THE CONTACT OWNS A 2009 KIA OPTIMA. THE CONTACT STATED THAT WHILE AT A STOP LIGHT, THE VEHICLE DOWN SHIFT WITH EXTREME FORCE. THE DEALER REPROGRAMMED THE TRANSMISSION COMPUTER AND THE GEAR SHIFT FAILURE WAS CORRECTED; HOWEVER, THE COMPUTER REPROGRAMMING AFFECTED THE VEHICLES ACCELERATION. THE VEHICLE FAILED TO ACCELERATE AFTER THE BRAKE PEDAL WAS RELEASED AND THE ENGINE BECAME IDLE. THE VEHICLE WAS TAKEN BACK TO THE DEALER FOR A TEST DRIVE WHERE THE FAILURE WAS DUPLICATED; HOWEVER, THE FAILURE COULD NOT BE CORRECTED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 32,553 AND THE CURRENT MILEAGE WAS 43,240. UPDATED 3/25/13 *CN THE CONSUMER STATED IT TOOK MONTHS TO FIGURE OUT THE PROBLEM. KIA DENIED THERE WAS EVEN A PROBLEM. IT WAS FINALLY DISCOVERED, WHEN THE DEALER REPROGRAMMED THE TRANSMISSION FOR A HARD SHIFT, THEY INADVERTENTLY CREATED A PROBLEM WITH THE ENGINE CONTROLS.

Mileage: 32,553

THE FIRST SIGNS OF ANY TROUBLE WITH THE VEHICLE STARTED IN FEBRUARY/MARCH OF 2011 WHEN THE SHIFTING ON THE VEHICLE WAS ERRATIC ON TAKEOFF AND ESPECIALLY BAD WHEN THE VEHICLE WAS SLOWING DOWN, ROUGHLY SHIFTING IN AND OUT OF GEAR. IT TOOK TWO OCCASIONS TO "FIX" THE ISSUE EVEN THOUGH A FEW WEEKS LATER THE SHIFTING APPEARED TO SUBSIDE IT STILL HAD THE OCCASIONAL ISSUE ON TAKE-OFF. THE ISSUE PROGRESSIVELY GOT TO THE POINT WHEN I LOST TOTAL ENGINE POWER WHILE CROSSING LANES OF TRAFFIC, ALMOST GETTING HIT. I STEPPED ON THE ACCELERATOR BUT NO MATTER WHAT I DID I COULD NOT GET THE VEHICLES RPM??S ABOVE 1500 (ABOUT 5MPH). TOOK IT TO THE DEALERSHIP WHERE THEY STATED THEY "FIXED THE PROBLEM". RETURNED TO DRIVING THE VEHICLE UNTIL MY WIFE HAD THE SAME ISSUE HAPPEN TO HER ABOUT 9 DAYS LATER COMING WITHIN INCHES OF GETTING HIT WHILE TURNING INTO A BUSINESS. TOOK THE VEHICLE BACK AGAIN AND WAS TOLD IT WAS "FIXED" TWO DAYS LATER. STARTED IT UP THE DAY AFTER IT WAS RETURNED AND HAD THE LOSS OF POWER ISSUE AGAIN. BESIDE THE POWER LOSS EVEN THE SHIFTING CONTINUED TO BE ROUGH AND ERRATIC. RETURNED IT YET AGAIN TO THE DEALERSHIP AND WAS TOLD IT WAS FIXED. CUSTOMER SERVICE DID NOT TAKE MY SAFETY CONCERNS SERIOUSLY. I AM STILL UNSURE OF THE STATUS OF THE VEHICLE AND I AM VERY CONCERNED ABOUT THE SAFETY OF THIS VEHICLE. I WILL FIND OTHER MEANS OF TRANSPORTATION UNTIL THIS VEHICLE IS RETURNED. BEWARE THAT THE POWER LOSS CAN HAPPEN AT ANY TIME CREATING VERY SERIOUS DRIVING CONDITIONS THAT COULD LEAD TO ACCIDENT OR INJURY. *TR

TL* THE CONTACT OWNS A 2009 KIA OPTIMA. WHILE DRIVING APPROXIMATELY 25 MPH AND APPLYING THE BRAKES, THE VEHICLE JERKED FORWARD WITH EXTREME FORCE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC. THE TECHNICIAN STATED THAT THE COMPUTER WOULD NEED TO HAVE A RE-LEARN PROCEDURE PERFORMED. AFTER THE PROCEDURE, THE FAILURE CONTINUED AND WAS TAKEN BACK TO THE DEALER WHERE THE TRANSMISSION FLUID WAS REPLACED. THE FAILURE CONTINUED AND WAS TAKEN TO THE DEALER A THIRD TIME. THE TECHNICIANS STATED THAT THE TRANSMISSION WOULD HAVE TO BE REPLACED. THE TRANSMISSION WAS ALSO REPLACED BUT TO NO AVAIL. THE APPROXIMATE FAILURE MILEAGE WAS 54,000.
