NHTSA Complaint #10956171 — 2003 JEEP LIBERTY

MY 2003 JEEP LIBERTY WAS RECALLED IN 2015 BECAUSE OF AN EXPLODING GAS TANK PROBLEM. I TOOK IT TO A DEALERSHIP BUT THEY REFUSED TO FIX THE PROBLEM, SAYING THAT RUST ON THE THREADS OF THE FRAME MOUNTING HOLES PREVENTED THEM FROM MOUNTING A HITCH TO FIX THE PROBLEM. I ASKED THEM IF THEY COULD THREAD A BIGGER HOLE, USE A BOLT AND NUT,OR JUST WELD THE NEEDED REPAIR PART ON - THEY REFUSED. I JUST THIS DAY TOOK MY JEEP TO A DIFFERENT DEALERSHIP TO HAVE A DIFFERENT RECALL REPAIRED SO I ASKED THEM TO CHECK CHRYSLER - JEEP RECORDS ON MY JEEP AND THEY HAVE IT LISTED AS SATISFIED FOR THE EXPLODING PROBLEM. THIS IS NOT TRUE, THEY REFUSED TO FIX IT EVEN AFTER SEVERAL E-MAILS TO THEM. NOW I SEE THAT THERE ARE STILL PROBLEMS WITH THE JEEPS EXPLODING EVEN AFTER REPAIRS HAVE BEEN MADE. HOW DO I GO ABOUT MAKING THIS COMPANY DO A PROPER REPAIR ON MY JEEP?
