2003 FORD EXPLORER SPORT Wheels Problems

WAS DRIVING THE VEHICLE WHEN I NOTICED SMOKE COMING OUT FROM UNDER THE HOOD. I PULLED OVER AS QUICK AS POSSIBLE INTO A STRIP MALL PARKING LOT. BEFORE I GOT OUT FLAMES WERE COMING OUT OF THE ENGINE COMPARTMENT. I RAN INTO A STORE AND GOT A FIRE EXTINGUISHER TO TRY AND PUT OUT THE FIRE. I FAILED, AS THE WHOLE FRONT OF THE EXPLORER WAS IN FLAMES AS WELL AS THE INTERIOR. THE VEHICLE IS A TOTAL LOSS. THE FIRE DEPARTMENT PUT IT OUT. I HAD THE VEHICLE FOR 7 WEEKS. THE USED DEALER WILL NOT TAKE ANY RESPONSIBILITY. SHOULD THEY? I PURCHASED THE VEHICLE ON MAR. 3,2014 AT OC AUTO EXPO IN WESTMINSTER, CA. *TR

THE LEFT FRONT HUB BEARING WENT BAD AND LUCKILY WE WAS NOT GOING DOWN THE HIGHWAY AT 55 MPH OR HIGHER, WE WAS ONLY GOING ABOUT 25-30 MPH. THE LEFT FRONT HUB BEARING FROZE UP AND WE DID A "U" TURN AND NO ONE WAS HURT. I HAD IT TOWED TO A SERVICE SHOP AND THEY TOLD ME WHAT THE PROBLEM WAS,AND THEY TOLD ME THAT THIS IS A MAJOR PROBLEM WITH THIS TRUCK. I CONTACTED FORD ON THIS MATTER AND THEY TOLD ME I HAD TO PAY FOR THE REPAIR BY MYSELF,BUT IF THE SAME PROBLEM IS ON MANY,MANY TRUCKS THIS IS BAD AND NOT SAFE. DO YOU HAVE ANY IDEAS? THE REPAIR SHOP CALLED ME AND TOLD ME WE SHOULD REPLACE THE TWO FRONT HUBS AND THE REAR...
