2004 GMC CANYON Structurebodydoor Problems

I WENT TO WORK THIS MORNING AND MY 2004 GMC CANYON TRUCK WAS RUNNING FINE, ABOUT 2 HOURS LATER I RAN AN ERRAND, STILL NO ISSUES WITH THE TRUCK. AROUND 2:00PM I WENT TO RUN ANOTHER ERRAND AND SMELT SOMETHING LIKE BURNING PLASTIC, I OPENED MY TRUCK TO FIND THAT MY FRONT PASSENGER SIDE DOOR WAS SMOLDERING. THE TRUCK WAS FULL OF SMOKE AND THERE IS NOW A HOLE IN THE SIDE OF MY DOOR FROM WHERE THE PLASTIC MELTED! I HAVE NO IDEA HOW THIS COULD HAVE HAPPENED, BUT THIS IS MY ONLY SOURCE OF TRANSPORTATION AND I OFTEN TAKE MY GRANDDAUGHTERS ON TRIPS WITH ME. I PLAN TO TAKE IT TO A GMC DEALERSHIP AND HAVE THEM LOOK AT IT SO MAYBE THEY CAN TELL ME WHAT CAUSED THIS PROBLEM. ALSO, THE BACK SEATS IN THIS TRUCK BLOCK A LOT OF THE VIEW OUT OF THE REAR WINDOW...

I HAVE A 2004 GMC CANYON WITH NO KEY HOLE IN PASSENGER SIDE TO UNLOCK DOOR. IT IS A EXTENDED CAB REAR SEATS FOR KIDS. WHEN I PARALLEL PARK IN STREET I HAVE TO TAKE MY KIDS INTO ONCOMING TRAFFIC TO UNLOCK DRIVERS DOOR WHILE THEY ARE IN HARMS WAY. THEY COULD GET HIT BY A ONCOMING CAR HEADING TOWARDS US. I FEEL IT SHOULD HAVE A SAFETY RECALL ON IT. THE 2007 MODELS HAVE A KEY HOLE IN BOTH DOORS I FEEL MINE SHOULD HAVE ONE AS WELL. THE DEALERSHIP DIDN'T INFORM ME ABOUT THE DEFECT. GM DOESN'T CARE ABOUT THEIR PAST MISTAKE, BUT THEY FIXED THE NEW MODELS WITH KEY HOLES. THEY DON'T FEEL I HAVE A VALID CLAIM WORTHY OF GETTING A KEY HOLE IN MINE FOR MY KIDS SAFETY,THEY SHOULDN'T HAVE TO ENTER THE VEHICLE FROM THE STREET. IT'S A SAFETY ISSUE. *TR
