I WAS TOLD BY THE DEALERSHIP THAT MY 2018 KIA OPTIMA PHEV WAS REPAIRED BUT AFTER I DROVE IT OFF THE LOT AND GOT ON THE FREEWAY THE WARNING LIGHT CAME ON AGAIN AND LOST ALL POWER. I ALMOST GOT INTO ANOTHER ACCIDENT BECAUSE OF THIS. THE DEALERSHIP SAID THEY WORKED WITH KIA TECHNICAL SUPPORT TO FIX MY CAR BUT APPARENTLY KIA DOESN'T KNOW WHAT'S WRONG WITH THEIR OWN CAR. THE VEHICLE HAS ONLY 19K MILES. I'M AFRAID FOR MY SAFETY AND MY FAMILIES THAT THIS WILL CONTINUE TO HAPPEN.

WHEN I WAS DRIVING ON THE HIGHWAY ON 2/14/2011 A "CHECK HYBRID SYSTEM" WARNING CAME ON, CHECK ENGINE LIGHT, TRIANGLE HEV LIGHT, A RED BATTERY LIGHT CAME ON AND CAR LOST ENGINE POWER. AFTER MY VEHICLE SLOWED TRAFFIC DOWN DUE TO NOT HAVING POWER I WAS BARELY ABLE TO PULL OVER TO THE SIDE OF THE ROAD BY COASTING THE CAR TO THE SHOULDER. IT WOULD NOT ACCELERATE WHAT SO EVER NOT EVEN WITH JUST THE ENGINE POWER. WHEN I PULLED OVER THE BIG CHECK HYBRID SYSTEM WARNING DISSAPEARED AND ONLY THE CHECK ENGINE LIGHT AND TRIANGLE HEV LIGHT STAYED ON. I HAD MY CHILDREN IN THE CAR AND ALMOST CAUSED AN ACCIDENT. IT WAS TOWED TO MY HOME AND AFTER I CONNECTED IT TO THE WALL PLUG FOR AN HOUR THE LIGHTS DISSAPEA
