WHILE I WAS DRIVING ON THE HIGHWAY GOING NO MORE 70MPH, WHEN THE ENGINE STARTED TO MAKE A WHINING NOISE AND THE TRUCK STARTED BUCKING. THEN THE TRUCK STOPPED ABRUPTLY AS IF SOMEONE HIT THE BRAKE THEN A LOUD POP NOISE. ONCE WE PULLED TO THE SHOULDER, SMOKE CAME THROUGH THE VENT AND FROM UNDER THE HOOD. WITHIN 15 SECOND FIRE SPARKS WAS SHOOTING FROM THE BOTTOM OF THE TRUCK THEN BY THE NEXT 10 SECOND FIRE STARTED SHOOTING FROM UNDER THE HOOD. THE ENTIRE FRONT OF THE TRUCK WAS ENGULFED. NO WARNING, NO CHECK ENGINE LIGHT, NOTHING. I HAVE ALWAYS HAD MY REGULAR MAINTENANCE DONE. LAST ONE DONE 10/2019. NOW I'M OUT OF A VEHICLE WITH NO WARNING FROM FORD. I'VE ONLY HAD THIS TRUCK 9 MONTHS WHICH I PURCHASED WITH AN EXTENDED WARRANTY IN MARCH 2019.
