2015 Kia Optima Hybrid Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I NOTICED THAT WHILE DRIVING PASS 35 MPH THE STEERING WHEEL GETS KINDA STUCK IN THE 12 O'CLOCK POSITION. IF I TRY TO STEER EITHER TO THE RIGHT OR LEFT IT GETS STUCK LITELY, NOW IT WILL NOT DO IT IF I'M MAKING A COMPLETE TURN! IT'S HARD DRIVING DOWN THE HIGHWAY BECAUSE YOU CAN'T KEEP THE VEHICLE STRAIGHT IN THE LANE BECAUSE OF THE STEERING WHEEL STICKING. JUST WANTED TO NOTE THAT IT DOES IT NOT ONLY ON THE HIGHWAY BUT ALSO ON CITY STREETS. IT'S ONLY HAPPENING AFTER I GO OVER APPROXIMATELY AFTER 35 MPH.

WHEN DRIVING THROUGH A NEIGHBORHOOD BETWEEN 20 - 25MPH THE HYBRID WARNING LIGHT ILLUMINATED WITH OVERHEAD VOICE STATING TO PULL OVER AND NOT DRIVE THE VEHICLE ANY FURTHER. IN THE PROCESS OF PULLING OVER THE CAR PROCEEDED TO LOSE ALL POWER. ELECTRICAL WITHIN CAR (LIGHTS, RADIO, ETC.) REMAINED ON BUT CAR WAS UNABLE TO ACCELERATE AND ENGINE WAS COMPLETELY OFF. THE CAUSE OF THE POWER LOSS IS STILL UNKNOWN, HOWEVER, WE WERE RUNNING ON HYBRID POWER AT THE TIME. THIS, WITH THE HYBRID MALFUNCTION INDICATOR LIGHT LEAD ME TO BELIEVE THIS IS A PROBLEM WITH THE HYBRID SYSTEM.
