2004 Cadillac Sts

I WAS STANDING AT THE BACK OF THE VEHICLE (CADILLAC SRX) AND I LEANED AGAINST THE BACK BUMPER WITH MY LEG, AND BURNED MY LEG ON THE TAILPIPE. I WAS STANDING "FLUSH" WITH THE BUMPER, AND IT BURNED MY LEG BECAUSE IT STICKS OUT TOO FAR (ABOUT 1/2 INCH TOO FAR) FROM THE BUMPER. THIS IS THE SECOND BURN THAT MY FAMILY HAS EXPERIENCED; ONE MONTH AGO MY 7 YEAR OLD SON BURNED HIS LEG ON THE TAILPIPE AS WELL. HIS BURN WAS MUCH WORSE - IT BLISTERED AND BLED AND SCABBED OVER. HE WAS CLIMBING INTO THE BACK OF THE VEHICLE TO RETRIEVE AN ITEM FROM THE TRUNK. I BELIEVE THAT CADILLAC NEEDS TO FIX THE TAILPIPES ON THE CAR BY EITHER SHORTENING THEM BY 3/4" OR 1 INCH, OR BY EXTENDING THE BUMPER SOMEHOW. THIS IS A DESIGN ERROR, AND A SAFETY ISSUE! I WANT CADILLAC TO TAKE CARE OF THIS BEFORE ONE OF MY YOUNGER KIDS, OR SOMEONE ELSE IS BURNED. CADILLAC HAS TOLD ME THERE IS NOTHING THAT THEY CAN DO, AND I DO NOT FIND THIS ACCEPTABLE!
