NHTSA Complaint #11182674 — 2008 JEEP COMPASS FWD

I RECENTLY DISCOVERED WHEN BRINGING MY 2008 JEEP COMPASS TO A MECHANIC THAT MY ENTIRE SUBFRAME IS COMPLETELY ROTTED OUT. THE SUBFRAME IS SO ROTTED OUT THAT HE SUGGESTED GETTING IT TOWED HOME BECAUSE THE WHEEL MIGHT COMPLETELY FALL OFF IF I HIT A POT HOLE HARD ENOUGH. THE BODY ON MY JEEP IS NEARLY FLAWLESS AND THE ENGINE ONLY HAS 70,000 ORIGINAL MILES. IS SEE ON OTHER SITES THERE IS A RECALL ON ALL THE COMPASS MODELS LEADING UP TO THE 2007 MODEL DUE TO THE SUBFRAME ROTTING OUT. I HAVE ALSO SEEN THIS IS A COMMON PROBLEM MANY CUSTOMERS HAVE HAD WITH THE 2008 MODEL LEAVING THE VEHICLE COMPLETELY WORTHLESS BEING THAT IT'S TOTALLED. HOW IS IT POSSIBLE FOR THE SUBFRAME TO BE COMPLETELY ROTTED OUT BUT MY ACTUAL FRAME IS COMPLETELY FINE? I'D REALLY LIKE SOME ANSWERS.
