Verbatim excerpts from NHTSA complaints, by component

Engine

5 reports2 fires
“The contact owns a 2015 Kia Optima Hybrid. The contact stated while driving 30-45 MPH, she heard abnormal knocking sounds coming from the engine. There were no warning lights illuminated. The contact stated she was able to continue to drive to her residence. The vehicle was taken to the dealer who diagnosed that the engine needed to be replaced. The dealer also informed the contact that the vehicle could not be repaired under NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine) because the VIN was not included in the recall. The manufacturer was notified of the failure but provided no assistance. The vehicle was not repaired. The approximate failure mileage was 98,000.”

Steering

2 reports
“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.”
