The engine on my 2010 Kia Optima suddenly seized without warning around 150,000 miles. The vehicle had no knocking sounds or warning signs prior to failure. A mechanic diagnosed the vehicle with a seized engine. This created a sudden loss of vehicle operation. I am concerned this may be related to the known engine failure issues reported in Kia vehicles.

1.We were driving and the car just cut off. Not from the lack of fuel but cut off in the middle of traffic. (Available for inspection) 2.The car stopping in traffic running about 65 mph causes the safety of all on the highway. A very dangerous situation. 3. The problem has showed itself numerous times. 4. The car had been inspected/checked after the incident. There was no errors on the computer after diagnosis. 5. No errors nor warning lights prior the incident. After the incident, the car cranks right back up without error.

Car would not engage into “Park” while attempting to park car in driveway. Shifter would not engage in any gear. Tried to reset button in center console. Contacted mechanic, he towed to garage. Plastic clip connected to cable broke. Earlier Kia’s had a recall due to this issue, why not all Kias due to it is still happening. I was very fortunate that this happened to me in my driveway and not on the highway. I understand there is the same part at the other end of the cable, connects to transmission and shifter, if it also breaks it is going to be very expensive to repair due to placement of the part. I had to rent a vehicle for work while part had to be ordered and replaced.

Rod bearing knocking noise. Vehicle stopped running when slowing down. Car is available for inspection. No warning lights come on. The rod bearing can pierce the engine and cause oil to leak and then a fire. Problem first identified by Monroe and then another independent when the car died in front of his shop- both confirmed this is a known issue with kias- but since ours is a 2010 it is not covered under the current recall for the same issue in years 2011 to 2013. I spoke with cooper Kia in Utica as I was looking for support with this issue and was told by Mike Digiovanni to call a lawyer. On a later call to Pat Stacey he said they don’t work for Kia and he stated that the salesman said I came in threatening to call a lawyer- not true- I was advised to call one. I had gone in explaining that I was upset as I thought this was a safe car for my 17 year old to travel in between college and work and it’s the same issue as the 2011-2013 recall

MY OPTIMA HAS 104,000 MILES. JUST LAST WEEK WHILE DRIVING ON WET ROADS, I LOST CONTROL AS THE POWER STEERING STOPPED WORKING. THE BATTERY LIGHT COMES ON DURING THIS PERIOD FOR BETWEEN 5-30 SECONDS AS YOU LOOSE ALMOST ALL CONTROL OF YOUR VEHICLE'S STEERING. JUST AS YOUR VEHICLE GAINS POWER STEERING AGAIN, A SCREECHING SOUNDS COMES FROM THE ENGINE COMPARTMENT (MAYBE BELTS RE-ENGAGING). IT HAS BEEN RAINING HER THE PAST WEEK AND THE ISSUE HAS HAPPENED ABOUT 8 TIMES. SOMETIMES DIRECTLY AFTER DRIVING THROUGH PUDDLES, AND SOMETIMES JUST WHILE DRIVING. THE ISSUE ONLY OCCURS THOUGH WHEN THE ROADS ARE WET. THIS IS A MAJOR SAFETY ISSUE.

WHEN COMING TO A STOP MY CAR SHIFTS FROM 3RD TO 2ND HER VERY ABRUPTLY. IT MAKES IT FEEL AS THOUGH I'VE SLAMMED ON MY BRAKES VERY SUDDENLY. IT ALSO DOES IT WHEN I SLOW MY CAR THEN PRESS THE GAS TO ACCELERATE SOMETIMES. I'VE TAKEN MY CAR TO THE DEALERSHIP OVER 5 TIMES SINCE FIRST PURCHASED BY MY MOTHER IN 2010 AND THE DEALERSHIP ALWAYS CLAIMED TO BE UNABLE TO NOTICE THE SUDDEN JERKING. THIS JERKING HAPPENS MOSTLY ON THE STREET DUE TO MY CONTINUAL STOP AND GO, BUT IT HAS ALSO HAPPENED WHILE GETTING ON THE FREEWAY AND DURING FREEWAY TRAFFIC.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
