Electrical system

17 reports1 related recall
“SINCE PURCHASING MY 2001 KIA OPTIMA, I HAVE HAD NOTHING BUT DIFFICULTY. I PURCHASED AN EXTENDED WARRANTY AT THE DEALERSHIP I PURCHASED IT FROM IN CASE I NEEDED REPAIRS. I GOT MY MONEY'S WORTH. BUT THE PROBLEMS I HAD ARE COMMON PROBLEMS WITH THE VEHICLE, LOCKS NOT WORKING, WINDOWS NOT ROLLING UP, PAINT PEELING OFF, TRANSMISSION PROBLEMS, CHECK ENGINE LIGHT CONSTANTLY ON, DECREASED ACCELERATION, HEAT SURGES WHEN GAS PEDAL RELEASED AND PRESSED AND THE LIST GOES ON. IT IS NOT HARD TO FIND OTHER KIA OWNERS WITH THE SAME PROBLEMS. THE REPAIR THAT BOTHERS ME THE MOST IS THE COMPLETE TRANSMISSION IT NEEDS. THERE IS 41,000 MILES ON THE VEHICLE. COMMON PROBLEMS THAT ARE WIDELY KNOWN AND SHOULD BE REPAIRED AT AN AUTHORIZED DEALER AT KIA MOTOR COMPANY'S EXPENSE. *TR”
