I WAS DRIVING MY CAR AT ABOUT 45MPH ON MY WAY TO WORK ON A HIGHWAY ROAD AND OUT OF NO WHERE IT JERKED AND THE CHECK ENGINE LIGHT STARTED FLASHING. CAR WOULD NOT ACCELERATE ABOVE 2,000 RPMS. WHEN THE CAR JERKED, IT WAS SO SUDDEN IT INJURED MY LOWER BACK. MY BACK HAS BEEN VERY SORE SINCE THIS INCIDENT. I THEN TOOK TO DEALER AND THEY SAID IT WAS A KNOWN ISSUE AND HYUNDAI HAD NOT RECALLED MY SPECIFIC CAR. DEALER WAS ABLE TO REPLICATE THE ISSUE. THE CLEARED THE CHECK ENGINE LIGHT AND SENT ME ON MY WAY. ONE MILE DOWN THE ROAD EXACT SAME THING HAPPENED. CAR IS CURRENTLY AT THEIR SHOP WITH NO ETA OF REPAIR.
