ENGINE
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.

NHTSA complaint #11640182 — an unverified report by a vehicle owner.
ENGINE
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

ENGINE
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.

ENGINE
WHILE DRIVING HOME ONE DAY IN DECEMBER 2015, EACH TIME I APPROACHED A STOP LIGHT, YIELD SIGN OR SLOWED TO A LOW SPEED (LESS THAN 15 MPH), MY VEHICLE WOULD SHUT-OFF MULTIPLE TIMES. MY IN MOTION SPEED WAS APPROX 45 MPH WHEN NOT APPROACHING A STOP LIGHT OR YIELD SIGN. IT HAPPENED BOTH WHEN I WAS TURNING AND GOING STRAIGHT ON MAIN ROADS WITH 2-4 LANES. THE DEALERSHIP AND ANOTHER ASME CERTIFIED MECHANIC BOTH STATE ENGINE FAILURE, WHICH SEEMS TO BE A WIDESPREAD PROBLEM WITH 2.4L ENGINES MANUFACTURED BY KIA AND HYUNDAI AROUND THIS YEAR UP TO 2015.
