WHILE DIVING MY 2016 HYUNDAI ELANTRA GT ON THE DALLAS NORTH TOLLWAY I FELT THE ENGINE LOSE HORSEPOWER. I APPLIED THE GAS JUST TO SEE IF IT WAS THE CAR CHANGING GEARS, I HEARD THE ENGINE REV, BUT THE CAR CONTINUED TO SLOW DOWN. I LOOKED DOWN AT MY DASHBOARD AND NOTICED THAT MY CHECK ENGINE LIGHT CAME ON AND STARTED TO BLINK FOLLOWED BY MY OIL LIGHT. THEN MY CHECK ENGINE LIGHT STOPPED BLINKED AND CONTINUED TO STAY ON FOLLOWED BY MY BATTERY LIGHT COMING ON. I TURNED MY HAZARDS LIGHTS ON AND WAS ABLE TO MAKE IT TO THE SHOULDER I PUT THE CAR IN PARK AND STARTED TO SEE WHITE SMOKE COMING OUT OF MY VENTS AND QUICKLY FILLING UP THE CABIN. I TURNED THE CAR OFF AND GOT OUT OF THE CAR AND WALKED AWAY. I DIALED DALLAS ROADSIDE SAFETY SERVICES AND WHILE SPEAKING TO THEIR DISPATCHER MY ENGINE CAUGHT FIRE. I WATCHED MY CAR GET COMPLETELY ENGULFED IN FLAMES BEFORE HELP ARRIVED.
