2010 MAZDA CX-9 Structurebody Problems

WE TOOK OUR 2010 CX-9 WITH 99,000 MILES THE MAZDA DEALER IN UNION NJ BECAUSE OF A NOISE IN THE CAR AND WERE TOLD THAT THE REAR SUBFRAME HAS ROTTED OUT AND IS DESTROYING THE REAR DIFF MOUNTING BOLTS. WE WERE ALSO TOLD THE EXHAUST SYSTEM IS ALSO ROTTED OUT AND THE VEHICLE IS UNSAFE TO DRIVE. IF WE GO OVER A POT HOLE, THE WHOLE UNDERCARRIAGE OF CAR CAN FALL OUT. THIS CAR WAS NOT KEPT AT THE BEACH AND WELL MAINTAINED.

I'VE OWN MY 2010 CX-9 SINCE NEW, AT 96K MILES THE BOLT MOUNT FOR THE HATCH BACK POWER LIFT RIPPED OUT OF THE SHEET METAL OF THE HATCH WITH A PIECE OF METAL AND BOLT FLYING. I USE THE CAR ONLY FOR PRIVATE USE AND NO HEAVY DUTY USAGE. BOLT LOOKED RUSTED (SORRY I THROUGH IT AWAY). THE MAZDA DEALER TELLS ME THAT IT IS A VERY UNCOMMON OCCURRENCE, AND THAT IS NOT COVERED BY MAZDA. I SEE IN BLOGS THAT IT IS NOT THAT UNCOMMON. THE BOLT AND METAL BREAKING MAY CAUSE GLASS BREAKAGE OR DAMAGE TO SOMEONE WHILE THE DOOR IS BEING OPENED.
