2012 DODGE CARAVAN Structure Problems

I PURCHASED A NEW VAN ON JULY 5, 2013. ON JULY 8, 2013, I DROVE 4 MILES, AND STOPPED AT A RED LIGHT. I ACCELERATED TO APPROX. 40 MPH, WHEN SUDDENLY THE VAN SHIFTED TO THE RIGHT MOMENTARILY, UPON WHICH I REGAINED CONTROL IMMEDIATELY. SUDDENLY, THE VAN JOLTED RIGHT AGAIN, JUMPED THE CURB, CLIMBED AN EMBANKMENT, AND WOULD NOT STOP ACCELERATING. I KEPT PUSHING THE EMC CONTROLS FORWARD....BUT IT WOULD NOT STOP THE VEHICLE. IT IS NOT THAT THE VEHICLE KEPT ACCELERATING, BUT RATHER, THE VEHICLE WOULD NOT STOP ACCELERATING. AS A RESULT, THE VEHICLE ONLY STOPPED WHEN I CRASHED THROUGH A LARGE EVERGREEN TREE (FRONT RIGHT PASSENGER AREA). THE VAN CONTINUED TO ACCELERATE UNTIL I RAN HEAD FIRST INTO A HARDWARE STORE, WHICH ULTIMATELY STOPPED THE VEHICLE. THERE WAS AN ANALYSIS PERFORMED, AND I EXPRESSED GREAT CONCERN OVER THE LACK OF INFORMATION DISCLOSED IN THE REPORT. THE ACCIDENT OCCURRED...
