NHTSA Complaint #10824726 — 2006 CHRYSLER PACIFICA

I HAVE A 2006 CHRYSLER PACIFICA, HAVE HAD IT 2 YEARS NOW. WHEN I TOOK IT TO THE GARAGE TO GET AN OIL CHANGE MY MECHANIC CALLED ME OVER TO THE SERVICE BAY TO SHOW ME THAT HE HAD FOUND THAT THE ENGINE SUB-FRAME WAS ALMOST RUSTED THROUGH. THE MECHANIC WENT ON TO TELL ME THAT WHEN IT FINALLY RUSTS THROUGH THAT THE ENGINE WILL DROP DOWN ON TO THE ROAD AND CAUSE ME TO LOSS ALL STEERING CONTROL AND THAT THE ENGINE MAY SLIDE UP UNDER THE CAR THUS RESULTING IN AN ACCIDENT, I HAVE TO DRIVE A MAJOR FREEWAY EVERYDAY TO GET TO WORK AND IF THAT HAPPENS TO ME THERE IS A GOOD CHANCE THAT I OR SOMEONE ELSE COULD GET SERIOUSLY HURT/AND KILLED. WHEN I CONTACTED MY LOCAL CHRYSLER DEALER HE ALL BUT LAUGHED WHEN I ASKED WHAT CHRYSLER WAS GOING TO DO ABOUT THIS SAFETY HAZARD, HE TOLD ME THAT CHRYSLER IS NOT GOING TO RECALL THESE CARS FOR THIS PROBLEM AND THAT I WAS ON MY OWN IN GETTING IT FIXED, NOW I AM STUCK WITH A CAR THAT HAS NO VALUE AND IS DANGEROUS TO DRIVE. WHAT CAN I DO?
