2009 Hyundai Sonata UNKNOWN OR OTHER

I STARTED MY CAR AND AS I STARTED TO TURN THE STEERING WHEEL SO I COULD PULL OUT OF THE PARKING SPACE SMOKE SPEWED FROM MY DASHBOARD. I LOOKED UP UNDER THE DASH AND NOTICED THE WIRING HARNESS IN FLAMES. I EXTINGUISHED THE FIRE. I THEN HAD THE CAR TOWED TO A HYUNDAI DEALER. THEY EXAMINED THE DAMAGE AND SAID TAT IT WOULD COST ME $4000 TO REPAIR IT AS I NEEDED A NEW WIRING HARNESS. HYUNDAI CLAIMS IT WASN'T A MANUFACTURERS DEFECT, EVEN THOUGH THE CAR WAS PURCHASED BRAND NEW AND THEREHAS BEEN NO ALTERATIONS OR MODIFICATIONS, THE SAME WIRING HARNESS IS USED IN KIA WHICH HAS A RECALL ON A WIRING HARNESS. I AM IN POSSESSION OF THE BURNT HARNESS AND IT CLEARLY HAS KIA WRITTEN ON IT
