Consumer Description

THE VEHICLE WAS IN MOTION AND HAD AN OIL CHANGE THE PREVIOUS DAY. THE VEHICLE LOST POWER AND AN AUDIBLE CLICKING OR TAPPING NOISE CAME ON WHILE DRIVING ON THE HIGHWAY. MY WIFE HAD JUST ENOUGH TIME TO PULL OFF INTO A LOCAL BUSINESS AND PARKED THE CAR. I TOOK IT TO KIA AND THEY ADVISED THERE WAS "SLUDGE" IN THE ENGINE AND WE HAD NOT BEEN MAINTAIN THE VEHICLE PROPERLY. OFFERED TO PRODUCE RECORDS BUT THEY ADVISED THEY STILL WOULD NOT COVER IT. *TR
