WHILE DRIVING DOWN THE INTERSTATE THE ENGINE BEGAN TO KNOCK. AS I PULLED OFF THE INTERSTATE THE ENGINE SHUT DOWN AND WOULD NOT RESTART. THE CAR ONLY HAS 96,000 MILES. THIS MOTOR HAS BEEN RECALLED BY HYUNDAI AND KIA BUT ONLY IN CERTAIN MODELS, WHILE THE ENGINE HAS YET TO BE RECALLED FOR ALL MODELS. I BELIEVE THE ISSUE IS THE CONNECTING ROD BEARINGS HAVE FAILED DUE TO INSUFFICIENT OIL FLOW. THE CAR'S OIL LEVEL WAS AT THE PROPER AMOUNT.

FIRST THING IN THE MORING WHEN I START MY CAR UP. YOU DON'T HEAR THE KNOCKING SOUND COMING FROM THE ENGINE BUT SOON AS THE CAR GET THE ENGINE WARMED UP YOU CAN HEAAR A VERY LOUD TICKING NOISE. EVEN AS YOU DRIVING THE CAR DOWN THE HIGHWAY YOU CAN STILL HEAR IT. ALSO THE STEERING IS VERY HARD TO OPERATE IT HAS BEEN LIKE THAT SINCE I BOUGHT THE CAR. I SAID SOMETHING TO KIA ABOUT IT THEY STATED THEY DIDN'T SEE A PROBLEM. IT'S VERY HARD TO BACKED UP AND TRY TURNING THE STEERING WHILE OPERATING THE CAR.

MY 2008 KIA OPTIMA STALLS RANDOMLY. IT DOES NOT MATTER IF THE CAR IS STATIONARY OR IN MOTION. THERE ARE TIMES THAT I START IT AND IT WILL STALL IMMEDIATELY AND SOMETIMES IT WILL STALL AS I AM BACKING OUT OF MY PARKING SPACE. THERE ARE ALSO TIMES WHEN I WILL BE DRIVING AND IT WILL STALL WHICH HAS NEARLY CAUSED AN ACCIDENT. THE PROBLEM DOES NOT PRODUCE A CHECK ENGINE LIGHT AND NO ONE HAS BEEN ABLE TO SUCCESSFULLY DIAGNOSE THE PROBLEM. THE ISSUE THAT I AM EXPERIENCING SOUNDS VERY FAMILIAR TO THE NEWER OPTIMAS THAT HAVE RECENTLY BEEN RECALLED. THE MOST RECENT STALLING OCCURRED YESTERDAY, 04/10/2017, AND THERE WAS A KNOCKING SOUND ALONG WITH THE STALLING OUT.

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

ENGINE STARTED MAKING A CLICKING SOUND WHEN THE CAR WAS ACCELERATING. TOOK MY CAR IN TO KIA AND FOUND OUT THAT ONE OF THE RODS IN THE SHORT ENGINE BLOCK WAS FAILING. MY ENGINE ONLY HAS 86464 MILES ON IT AND ITS AN 2008. BOUGHT THE CAR WITH 69000 MILES ON IT, ONLY HAD THE CAR FOR 7 MONTHS BEFORE THE ENGINE BEGAN TO FAIL. I TOOK THIS PROBLEM UP WITH THE DEALERSHIP AND KIA HEADQUARTERS. WAS TOLD THEY WOULD NOT HONOR THE 100,000 MILE WARRANTY BECAUSE THE CAR WAS NOT CERTIFIED. I WAS NOT OFFERED A WARRANTY/ DID NOT OBTAIN AN EXTENDED WARRANTY, WAS NOT DISCLOSED TO THAT THE 10 YEAR 100,000 MILE WARRANTY DID NOT EXTEND TO THE NEXT OWNER, NOR WAS I TOLD THAT THEY COULD NOT CERTIFY IT. WAS NOT OFFERED A CAR FAX, BUYERS GUIDE OR TOLD ABOUT ANY TYPE OF WARRANTY INFORMATION. KIA DEALERSHIPS DO NOT CERTIFY CARS AFTER 60,000 MILES EVEN THOUGH THERE IS STILL 40,000 MILES ON THE ORIGINAL WARRANTY. THERE WAY OF GETTING AROUND HAVING TO HONOR THE ORIGINAL WARRANTY AND OFFER THIS TO THE NEXT OWNER(S). VERY ANGRY WITH KIA, THEY ARE DECEITFUL, LIARS, AND DO NOT STAND BEHIND THEIR PRODUCT. THEY SHOULD NOT BE ABLE TO SELL ANY CARS WITH OUT THE ORIGINAL WARRANTY BEING OFFERED! WITH A HISTORY OF THERE ENGINES FAILING AND HAVING MAJOR MECHANICAL PROBLEMS I FIND IT VERY DISGRACEFUL HOW THEY OPERATE AND ENFORCE POLICY. IF MY ENGINE ACTUALLY FAILS WHILE I AM DRIVING, I COULD EASILY GET INTO A MAJOR ACCIDENT AND BE CRITICALLY INJURED. I DRIVE A MAJOR FREEWAY EVERY SINGLE DAY, AND TO ME THIS IS VERY DANGEROUS. IF MY ENGINE FAILED AND STALLED GOING 70 MILES AN HOUR, I COULD EASILY BE KILLED OR GET INTO A MAJOR ACCIDENT. PLEASE RECALL 2008 OPTIMAS OR COMPLAIN TO KIA REGARDING THERE POLICY. THEY SHOULD HAVE TO OFFER AND STAND BEHIND THE ORIGINAL WARRANTY OR BE REQUIRED TO DISCLOSE THERE POLICY TO CUSTOMERS UP FRONT. COMMERCIALS AND PARKING LOT ADVERTISE PER OWNED CERTIFIED CARS AND 100000 WARRANTY. *TR

MY 17 YEAR OLD DAUGHTER WAS DRIVING MY 2008 KIA OPTIMA WHEN SHE NOTICED A LOUD CLATTERING NOISE COMING FROM UNDER HOOD. SHE PULLED OVER AT A GAS STATION. A GENTLEMAN THERE CHECKED THE OIL AND SAID THAT IT WAS LOW, HE ADDED 2 QUARTS, I CHANGE THE OIL IN THIS VEHICLE PERSONALLY AND KNOW THAT IT DOESN'T USE ANY OIL. SHE DROVE HOME 3 MILES WITH THE ENGINE STILL CLATTERING. I CHECKED THE OIL AND THE STICK SHOWED 1 QUART LOW. I IMMEDIATELY DRAINED THE OIL AND PUT ON A NEW FILTER AND POURED 4.5 QUARTS IN THE ENGINE. I STARTED UP THE CAR, IT CLATTERED AND RAN IN THE DRIVEWAY FOR 10 MINUTES AND THE ENGINE LOCKED UP. THE KIA ROADSIDE PICKED UP THE CAR AND TOWED IT TO THE DEALER. HE INFORMED ME THAT THE ENGINE WAS 2 QUARTS LOW ON OIL. THERE WAS NO OIL LEAKING FROM THE CAR, WHERE DID THE OIL GO??? THE DEALER SAYS THAT I NEED TO COME UP WITH RECEIPTS BEFORE THEY WILL HONOR THE WARRANTY. IF MY DAUGHTER WOULD HAVE BEEN DRIVING THE CAR WHEN THE MOTOR LOCKED UP, SHE WOULD HAVE NOT BEEN ABLE TO CONTROL IT WITH ALL POWER GONE. I HAVE READ MANY CASES JUST LIKE THIS ONE. SOMEONE WILL GET SERIOUSLY HURT FROM THIS KIND OF ENGINE FAILURE. WILL KIA STEP UP AND RECOGNIZE THAT MAYBE THE OIL CONTROL VALVE IS THE WEAK LINK. MY DEALER SAID THAT WAS WHAT SENT THE CODE TO THE COMPUTER AND OVER-RETARDED THE TIMING. *TR

MY 2008 KIA OPTIMA STALLED, WITHOUT WARNING, WHILE DRIVING APPROXIMATELY 35-40 MPH ON A BUSY HIGHWAY NEAR AN EXIT. THE CAR LOST ALL POWER, INCLUDING STEERING. THE CAR ENDED UP RIDING A GUARDRAIL AND LANDED ON TOP OF IT. THE END RESULT WAS, FOR ME, A BROKEN NECK! THERE WAS ABSOLUTELY NO WARNING PRIOR TO THIS HAPPENING. I WAS ON MY WAY TO PICK MY 3 YEAR OLD SON UP FROM SCHOOL. HAD HE BEEN IN THE CAR, THIS MAY HAVE BEEN CATASTROPHIC! MY AIRBAGS DID NOT DEPLOY! THIS IS UNACCEPTABLE. THE CAR IS UNDERGOING BODYWORK REPAIRS AND I AM SCARED TO DEATH TO STEP FOOT IN THIS DEATH TRAP EVER AGAIN. CALLS TO THE KIA DEALER WHERE I BOUGHT THE CAR GO UNANSWERED, AS THEY USUALLY DO. THIS IS SERIOUS! IF YOUR OPTIMA HAS STALLED WHILE DRIVING WITHOUT WARNING PLEASE POST A COMPLAINT. THIS NEEDS TO BE A RECALL! *TR

DECEMBER 28, 2011, I NOTICED THAT MY AIRBAG LIGHT LOCATED ON THE DASHBOARD CONTINUOUSLY STAYS ILLUMINATED. I HAVE TAKEN IT TO THE DEALER TO GET IT CHECKED OUT. I WAS TOLD THAT THE AIRBAG SENSORS ARE LOCATED IN THE DRIVER/ PASSENGER SEATS. THE MECHANIC AT KIA DEALER TRIED TO FIX THE PROBLEM, BUT WAS UNSUCCESSFUL. THE SERVICE REPRESENTATIVE INFORMED ME THAT THEY WOULD HAVE TO REPLACE THE SENSORS. I'VE VIEWED THE COMPLAINTS OF PEOPLE THAT OWN KIA OPTIMA 2008. IT STATES THAT THESE CARS WERE RECALLED BECAUSE OF SIGNIFICANT AMOUNT OF DEFECTS. (I ONLY HAVE 43,000 MILES) IN ADDITION, A WEEK AGO I'VE STARTED HEARING A TICKING NOISE COMING FROM THE ENGINE AREA WHEN I ACCELERATE GOING UP IN A ROLLER COASTER CLIMBING POSITION. THANK YOU FOR YOUR EXPEDITIOUS RESPONSE. *TR

2008 KIA OPTIMA 4CYL AUTOMATIC. I LIVE IN FLORIDA, HOT ALL THE TIME, USE AIR ALMOST ALL YEAR. CAR WILL STALL OUT WHILE IN MOTION WITHIN FIRST FEW MINUTES WHILE AC IS ON WHEN I AM SLOWING DOWN TO STOP SIGNS OR WHEN CROSSING INTERSECTIONS WHERE I HAVE TO GET ACROSS QUICKLY THEN LET OFF GAS TO MAKE TURN. CAR BECOMES HARD TO STEER WHEN ENGINE CUTS OFF, WORSE THAN A CAR WITHOUT POWER STEERING, SOMETIMES IT FEELS LIKE IT WONT MAKE IT THROUGH THE INTERSECTION TO THE MEDIAN SAFELY. CAN START THE CAR AGAIN, BUT IT TAKES A FEW SECONDS TO THROW CAR INTO NEUTRAL, TURN IGNITION, AND PUT BACK INTO DRIVE. AS I SAID THIS HAPPENS A LOT WHILE GOING THROUGH THE TURN OF INTERSECTION/ DIVIDED HIGHWAY AND THOSE FEW SECONDS MAKE THE DIFFERENCE BETWEEN A SAFELY TIMED TURN AND A POTENTIAL COLLISION. PROBLEM OCCURS FREQUENLTY FOR A WEEK OR TWO, THEN GOES AWAY FOR A WHILE AND COMES BACK. ONCE THE ENGINE HAS WARMED UP AND HAS BEEN MOVING FOR 5 MINUTES OR SO, IT DOESN'T HAPPEN. TOOK IT TO KIA DEALERSHIP SINCE THIS VEHICLE HAS 45000 MILES ON IT AND IS STILL UNDER MANUFACTURES BUMPER TO BUMPER WARRANTY, DEALERSHIP SERVICE DEPARTMENT SAID THEY WERE AWARE OF THE ISSUE WITH THAT GENERATION OF OPTIMAS AND THAT IT WAS ONLY WITH THE 4CYL MOTORS, THE V6'S WERE FINE. SERVICE DEPARTMENT SAID AT THIS TIME THERE IS NOT A FIX FOR IT AND WOULD NOT REPLACE ANY PARTS SINCE THEY DON'T KNOW WHICH PART(S) ARE CAUSING THE MALFUNCTION. WAS TOLD TO LET MY CAR WARM UP LONGER AND TO HOPE THAT KIA/HYUNDAI COMES UP WITH A RECALL ON IT SOON. *KB

2008 KIA OPTIMA STALLS WHILE IN MOTION. VEHICLE WILL SHUT ITSELF OFF. IT IS AS IF SOMEONE REACHES OVER AND TURNS THE KEY OFF. IT HAS HAPPENED WITH THE CAR STANDING STILL AND WITH THE CAR IN MOTION. STALLING USUALLY OCCURS WITHIN FIRST FEW MINUTES OF OPERATION AND WITH HOT OUTDOOR TEMPERATURES. FIRST VISIT TO KIA RESULTED IN REPLACED FUEL TANK (CODES FOR BAD ROLL OVER VALVE). PROBLEM WENT AWAY FOR ABOUT A YEAR THEN CAME BACK. CAR HAS BEEN IN THE SHOP 4 TIMES OVER THE LAST MONTH AND A HALF. SHOP CAN'T DUPLICATE THE PROBLEM, SO THEREFORE, CAN'T FIX THE PROBLEM. THE CAR IS SUBJECT TO SHUTTING ITSELF OFF AT ANYTIME WITH NO WARNING, THE LAST OCCURRENCE HAPPENED JUST BEFORE MY WIFE WAS TO MERGE ONTO A BUSY HIGHWAY. APART FROM FUEL TANK, DEALER HAS DONE NOTHING SUBSTANTIAL TO REPAIR THE ISSUE (COMPUTER UPDATE, TIGHTENED LOOSE WIRES). *TR

2008 KIA OPTIMA EXV6, SINCE NEW, WHEN LIGHTLY BRAKING WHILE DECELERATING FROM 40 MPH, THE CAR DOWNSHIFTS AND HAS AN ACCELERATION SURGE AT AROUND 25 MPH. WHEN COMPLAINING TO THE DEALER, THEY SAID THE KIA'S WERE MADE THAT WAY. THIS IS AN UNSAFE CONDITION THAT CAN CAUSE A REAR END COLLISION. THE CAR SHOULD HAVE NORMAL ENGINE BRAKING THAT ALLOWS FOR CONTINUOUS DECELERATION AS LONG AS THE ACCELERATOR PEDAL IS NOT TOUCHED. THANK YOU FOR YOUR CONSIDERATION OF THIS COMPLAINT. *TR
