2007 GMC SIERRA Structurebody Problems

MY DASH HAS LARGE GAPS/CRACKS IN THE DASHBOARD. THESE RANGE FROM THE WINDSHIELD ALL THE WAY THE FRONT PIECE OF TRIP. THE DASH IS COMPLETELY SEPARATED. RIGHT IN THE CENTER OF THE DASH, AROUND THE AIRBAGS, AND THE OTHER SMALLER PARTS OR THE DASH ARE CRACKED TOO. I USE A SUN SHIELD, SO THAT IS NOT THE CASE. MY DAUGHTER AND I HAVE BOTH CUT OUR HANDS ON THE DASH. SHE WAS SO SURPRISED WHEN SHE GOT IN THE TRUCK THAT SHE ASKED IF I HAD A WRECK, AND THEN RAN HER HAND OVER THE DASH AND CUT HER PALM AD TWO FINGERS. I ALSO CUT MY HAND WHILE TRYING TO CLEAN IT SO THAT STUFF DOES NOT DROP DOWN THE CRACK, SUCH AS DIRT OR DUST, CAN'T THAT START A FIRE WITH THE WIRES AND THE HEATER DOWN THERE? ANOTHER THING IS MY VENTS DON'T WOK LIKE THEY ARE...

DRIVER DOOR. WON'T UNLOCK HAVE TO GET OUT OF TRUCK ON RIGHT SIDE , TOOK IT TO DEALER SAID IT NOT AND EASY FIX OVER 1200 DOLLARS TO REPAIR, LOOK ON LINE A LOT OF OTHER WHO HAVE SERRIA TK HAVE HAD PROBLEMS WITH THE LOCKING SYSTEM NOT WORKING, WITH THE DOOR NOT UNLOCKING HAS TO BE A SAFTEY ISSUE.

THE REAR END WENT OUT AND FENDERS ARE COMING LOOSE UNIVERSAL JOINTS ARE GOING OUT REPLACED THEM, RADIO WENT OUT, FRONT BUMPER FELL OUT OF PLACE, FUEL RELAY SWITCH WENT OUT , WHAT HAPPENED TO GMC TOP OF THE LINE TRUCKS AND I'VE HAD GMC BEFORE AND NEVER HAD THIS PROBLEM AND HAD THEM FOR YEARS PART STORE DOES NOT HAVE RIGHT NUMBERS FOR UNIVERSAL JOINT. *TR
