2009 Kia Optima Engine Problems

Your engine seized while you were driving, and now your car won't start or stay running. A bearing or other internal engine component failed despite your car having only 126,000 miles. The engine will likely need to be rebuilt or replaced entirely.

While driving at 35 MPH, your car made a loud knocking noise and then shut off completely. Your battery and check engine lights came on, and the car stalled several more times on the way to a mechanic. The mechanic found metal shavings in the oil pan, indicating your engine has suffered serious internal damage. Your engine will likely need to be completely replaced.

Your car is experiencing harsh, abrupt downshifts when slowing down that feel like the brakes were suddenly applied hard, causing the vehicle to jerk forward. This happens most noticeably when the car first starts and typically goes away once the engine warms up. A Kia dealer reprogrammed your transmission control module, which fixed the problem temporarily, but it has returned after a couple of years. The fix may involve updating or replacing the transmission control module software again.

THE ENGINE STARTED KNOCKING TWO MONTHS AGO AND YESTERDAY THE CHECK ENGINE LIGHT CAME ON WHILE DRIVING ON THE HIGHWAY RESULTING IN THE CAR SHUTTING OFF WITH NO WARNING.

MY 2012 KIA OPTIMA WAS FOUND TO HAVE A LEAKING OIL LINE WHICH FEEDS LUBRICATION OIL FROM THE ENGINE TO THE TURBOCHARGER. THIS OCCURRED AT 58,000 MILES, WELL WITHIN THE 100,000 MILE WARRANTY FOR THE DRIVE TRAIN. HOWEVER, THE DEALER INFORMED ME THAT THE OIL SUPPLY LINE WAS NOT COVERED BY THE WARRANTY, BUT THE ENGINE AND TURBO WERE. THE LOSS OF THIS LINE WOULD RESULT IN THE FAILURE OF THE ENGINE DUE TO NO OIL, AS WELL AS THE TURBO, AND THIS WAS MOST LIKELY TO FAIL WHEN UNDER ACCELERATION IN TRAFFIC AS THAT IS WHEN THE LOAD ON THESE COMPONENTS IS GREATEST. FAILURE OF THE ENGINE AT THIS TIME COULD RESULT IN CATASTROPHIC CONSEQUENCES IN HEAVY TRAFFIC. EVEN IF THE LINE DID NOT FULLY FAIL, THE LEAKING OIL IS LOCATED AT THE TURBO HOUSING WHICH IS PART OF THE EXHAUST SYSTEM AND IS LIKELY, AFTER SOME TIME, TO RESULT IN AN ENGINE FIRE WHICH WOULD LIKELY DESTROY THE CAR. SINCE THIS COMPONENT, THE OIL SUPPLY LINE CONNECTS THE ENGINE AND THE TURBO I FIND THAT IT IS AN ESSENTIAL PART OF THE DRIVE TRAIN AND SHOULD BE COVERED BY THE MANUFACTURER UNDER THE WARRANTY. IT ALSO IS A SEVERE POTENTIAL HAZARD TO THE DRIVER OF THE VEHICLE. I WISH TO ENTER MY CONCERNS TO THE NHTSA.

I HAVE THE SAME PROBLEM AS OTHER DESCRIBE HERE. I HAD THIS ISSUE IN 2011 WHEN SLOWING DOWN FROM 10 MILE SPEED (BELIEVE) . DEALER FIXED WITH PROGRAMMING (AS THEY SAID). NOW RECENTLY LAST THREE MONTH HAPPENING EXACTLY LIKE FOLLOWING POST. I HAVE CONTACTED DEALER AND HAVE APPOINTMENT THIS WEEK. (SEE WHAT HAPPENS..) =========================== 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

THIS CAR WAS PURCHASED IN MARCH 2010 AND HAD ONLY 2400 MILES ON IT WHEN THE OIL PUMP FAILED. IT TOOK CITRUS MOTORS IN ONTARIO, CA ALMOST TWO WEEKS TO ACQUIRE THE PART AND REPLACE IT. UPDATED 01/20/11 *BF
