2008 Kia Optima Transmission Problems

Your car experiences multiple electrical problems that started right after you bought it in November 2024. The engine loses power during idle or deceleration until you press the gas pedal, and the alternator has already needed replacement once and may need it again soon. All your lights—headlights, brake lights, dashboard lights, and dome light—flicker on and off, which is especially dangerous at night when you can't see the road; this flickering gets worse when you're slowing down. Your airbag warning light stays on constantly with multiple fault codes that return shortly after being cleared, leaving the airbag system's status unclear. This likely requires comprehensive electrical system diagnosis and repair, including possible alternator replacement, wiring inspection, and airbag system troubleshooting.

While driving, you tried to shift into reverse but your car got stuck in drive mode and wouldn't respond to gear shift inputs. Your vehicle became locked in drive and wouldn't move, and this resulted in a crash.

Your shifter cable detached while parking, causing the transmission to remain in Drive even though the shifter appeared to be in Park. Your car continued rolling and required the emergency brake to stop it. The dealer diagnosed that the entire shift cable needs to be replaced to restore proper transmission control.

Your check engine light came on, and a mechanic diagnosed a transmission failure. You discovered after purchase that the vehicle's actual mileage (217,000 miles on the title) was significantly higher than what was shown at sale (198,000 miles), suggesting the odometer may have been rolled back. This transmission issue may require a complete transmission rebuild or replacement.

Your transmission got stuck in neutral and won't shift into drive, leaving you unable to move your car. You noticed there was a recall issued in March 2011 for transmission shift linkage issues on your model, but your VIN isn't showing the recall in the system even though you bought the car after the recall date. The dealership refused to review the recall information you found, so you're unsure how to get it fixed.

Your transmission locked up while you were turning in a driveway, causing your vehicle to get stuck in drive mode and unable to start or move. This happened suddenly even though the car was working fine moments before. The issue may involve transmission fluid, solenoids, or internal transmission components that need inspection and repair.

While driving in reverse, your transmission suddenly shifted into neutral without any warning, and you couldn't shift it back into drive afterward. A mechanic found that the shifter cable was broken and needed to be replaced to restore normal transmission operation.

TL* THE CONTACT OWNS A 2008 KIA OPTIMA. WHILE THE CONTACT WAS WAITING TO HAVE THE OIL CHANGED IN THE VEHICLE, HE SHIFTED FROM PARK INTO NEUTRAL; HOWEVER, THE GEAR FAILED TO ENGAGE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED BY AAA TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE SHIFTER CABLE DISCONNECTED FROM THE SHIFTER. THE VEHICLE WAS NOT REPAIRED. GREENWAY KIA OF RIVERGATE (1536 GALLATIN PIKE N, MADISON, TN 37115, (615) 860-9888) WAS CONTACTED AND STATED THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT ASSIST. THE FAILURE MILEAGE WAS APPROXIMATELY 79,000.

TL* THE CONTACT OWNS A 2008 KIA OPTIMA. WHILE ATTEMPTING TO PARK THE VEHICLE, IT CONTINUED TO MOVE WITHOUT WARNING WHILE IN THE PARK POSITION. THE CONTACT HAD TO APPLY THE EMERGENCY BRAKE TO STOP THE VEHICLE. ONCE THE EMERGENCY BRAKE WAS APPLIED, THE VEHICLE WAS UNABLE TO START. THE VEHICLE WAS TOWED TO SONS KIA (100 SONS DR, MCDONOUGH, GA 30253, (678) 619-1393) WHERE IT WAS DIAGNOSED THAT THE THROTTLE NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED PER NHTSA CAMPAIGN NUMBER: 13V114000 (SERVICE BRAKES, HYDRAULIC, EXTERIOR LIGHTING); HOWEVER, THE DEALER REFUSED TO REPLACE THE TRANSMISSION SHIFTER CLAIMING THAT THE SHIFTER WAS NOT INCLUDED IN THE RECALL.

MY HUSBAND WENT TO WALMART TO DROP OFF A MOVIE. WHEN HE CAME OUT HE SAW ONE OF THE EMPLOYEES HOLDING THE CAR FROM BEHIND BECAUSE IT WAS ROLLING BACK. MY HUSBAND PUT THE CAR IN PARK AND TURNED IT OFF AND THE CAR STILL ROLLED BACK. WHEN HE GOT IN THE CAR AND TURNED IT ON THE HEAD BOARD SHOWED IT WAS ON 'N'. NO CHECK ENGIN LIGHT OR ANY OTHER WARNING LIGHT WAS ON. THE SHIFT GEAR WAS STUCK ON N. AND IF MANUAL BRAKE IS NOT ON THEN THE CAR WILL ROLL BACK. YOU CAN MOVE THE GEAR STICK IN CAR TO PARK OR DRIVE BUT THE ACTUAL CAR IS STUCK ON N. SHIFT GEAR WILL NOT CHANGE FROM N. IF IT HAD NOT BEEN FOR THE WALMART EMPLOYEE STOPPING OUR CAR THAN IT COULD HAVE BEEN ALOT WORSE BY CRASHING INTO OTHER CARS BEHIND IT OR EVEN RUNNING OVER SOMEBODY CAUSING A FATALITY!!! CALLED KIA COMPANY TO REPORT IT BUT THEY DENIED IT BEING RELATED TO THE RECALL THAT SHOWS ONLINE ON KIA OPTIMAS 2006-2008. THEY TOLD ME ONLY SPECIFIC OPTIMAS HAVE THAT RECALL. WE HAVEN'T EVER HAD ANY ISSUES WITH OUR CAR SINCE WE BOUGHT IT NEW IN 2008. WE HAVE ALWAYS MAINTAINED IT AND TAKEN GOOD CARE OF IT. THIS IS A FIRST FOR OUR CAR AND THIS INCIDENT WE HAD WITH OUR CAR IS THE SAME DESCRIPTION AS THE RECALL. WE FEEL THAT KIA SHOULD COVER THIS COST DUE TO IT BEING A MANUFACTUER ERROR. THE RECALL STATES ' INCORRECTLY INSTALLED CABLES HAVE THE POTENTIAL TO COME LOOSE FROM THE TRANSMISSION, DISABLING THE SHIFTER. IF THE CABLE COMES LOOSE, A CAR IN PARK WOULDN'T SHIFT INTO ANY GEAR WHILE A VEHICLE ALREADY IN GEAR WOULDN'T SHIFT TO REVERSE, NEUTRAL OR PARK. IF A CAR WAS PARKED AND ACCIDENTALLY LEFT IN GEAR, AND IF THE PARKING BRAKE WAS NOT APPLIED, THE CAR COULD POTENTIALLY ROLL AWAY AND CAUSE AN ACCIDENT OR INJURY.' KIA SHOULD BE HELD RESPONSIBLE AND TAKE CARE OF THE PROBLEM AND STOP SAYING ONLY SPECIFIC VEHICLES HAVE THE RECALL. WELL MY CAR DID!! ITS A 2008 KIA OPTIMA AND HAD THE SAME INCIDENT HAPPEN THATS ON RECALL. HELP!!

THE GEAR SHIFTER IS FREELY ALLOWED TO MOVE, YET THE ELECTRICAL SYSTEM IS REGISTERING THAT THE CAR HASN'T LEFT NEUTRAL. (EXAMPLE: WHEN I PLACE THE CAR IN P(ARK), THE DISPLAY ABOVE THE ODOMETER WILL REMAIN IN N(EUTRAL). THE SHIFTER IS FREELY ALLOWED TO MOVE WHEN THE CAR IS ON AND THE BRAKE IS PRESSED DOWN AS USUAL.

MY 2008 KIA OPTIMA WAS A GOOD CAR WIITH NO PROBLEMS AT ALL SO WHEN MY CAR CUT OFF ON I 95 DURING RUSH HR. I WAS SCARED TO DEATH. AS I WAS ENTERING THE RAMP FOR I-95 MY CHECK ENGINE LIGHT CAME ON . I HAD A CLICKIN NOISE IN ENGINE BUT WITHIN LESS THEN 2 MIN. AS I MERGED INTO TRAFFIC MY ENGINE SHUT OFF AND WOULD NOT TURN BACK ON. AFTER GETTING IT TOWED TO DEALER ,EVERYONE INCLUDING DEALER THOUGHT IT WAS THE STARTER OR ALTERNATOR BECAUSE OIL WAS FINE AND NOTHIN WAS WRONG.. THE DEALER SAID HE COULDNT FIND ANYTHING THAT SHOULD HAVE CAUSED ENGINE TO LOCK . HE ALSO WAS CONFUSED.STILL TO THIS DAY NO BODY CAN TELL ME WHY THIS HAPPENED. I COULD HAVE BEEN KILLED OR SERIOUSLY INJURED ON THE HIGHWAY.NOW MY ONLY OPTION IS TO BUY A ENGINE WHEN MY OLD ONE SHOULD HAVE STILL HAD A LOT MORE MILES LEFT. *TR

MY NEW KIA HAS ABOUT 700 MILES ON IT, AND WHEN I PARK IT ON AN INCLINE SUCH AS THE ONE ENTERING MY GARAGE AND I SHUT THE ENGINE OFF AND PLACE IT INTO 1ST GEAR (IT IS A STANDARD SHIFT), THE CAR SLIPS BACKWARD. UPON TAKING IT TO THE DEALERSHIP, THEY INFORMED ME THAT THE ENGINE COMPRESSION IN THE CAR IS TOO LOW TO HOLD THE CAR IN 1ST GEAR ALONE, AND THAT THE EMERGENCY BRAKE MUST ALSO BE APPLIED. MY QUESTION IS: I HAVE A 3 YR OLD GRANDSON, BUT LET'S SUPPOSE HE IS 5 AND HE WANTS TO GO OUT AND PLAY, WHICH HE COULD DO UNSUPERVISED, AND HE DECIDES HE WANTS TO GET IN GRANDMA'S CAR AND PLAY AND ACCIDENTALLY LETS THE EMERGENCY BRAKE OFF. MY CAR WOULD THEN BEGIN SLIPPING BACKWARD WITH THE CHILD INSIDE. I CONSIDER THAT TO BE A BIG SAFETY HAZARD. FURTHER I HAVE ALWAYS BEEN TAUGHT THAT IF YOUR PARKING BRAKE FAILS, THE GEAR BOX WOULD STILL KEEP THE CAR FROM ROLLING BACKWARDS. 2. MY CAR STALLS FAIRLY FREQUENTLY IN 1ST GEAR, AND VERY FREQUENTLY IN REVERSE, BOTH INCIDENTS OCCUR WHEN THE CAR IS INCHING UP OR OUT OF A PARKING SPACE. THE DEALERSHIP SAID THEY ARE LOOKING INTO IT AND WILL LET ME KNOW, BUT AGAIN, IN HEAVY TRAFFIC THIS RUNS THE RISK OF BEING REARENDED. IF YOU CAN INFORM ME ON EITHER OF THESE ITEMS, I WOULD APPRECIATE IT AS THE DEALERSHIP DOESN'T SEEM INCLINED TO DO ANYTHING ABOUT EITHER PROBLEM AT THE MOMENT. IT MAY JUST BE A FUEL TO AIR RATIO MIX GOING INTO THE ENGINE ON THE STALLING, WHICH SHOULD BE SIMPLE ENOUGH TO FIX, BUT SURELY THE COMPRESSION IN THE ENGINE CAN ALSO BE ADJUSTED SO THE CAR WILL NOT SLIP BACKWARD WHEN IN FIRST GEAR. *TR
