I HAVE TALK TO GM EXECUTIVE OFFICE THAT FIX THE HUB ASSEMBLY AND TAILGATE RECALLS PROBLEM IN 2011 BUT UNWILLING TO DEAL WITH IT NOW AFTER TALKING TO GM DAN. I THINK I NEED OUT SIDE COUNSEL AND ENGINEERING FIRM TO TEST AND TESTIFY ON MY BEHAVE AND 2,300 OTHER OWNERS WITH THE SAME PROBLEM.

I BOUGHT THIS TRUCK FROM DEALER WITH 40151 MILES. I HAVE THIS TRUCK FROM 2007 TO PRESENT TIME WITH THE MILEAGE AT 51,000 MILES. THE TRUCK HAS BEEN USED FOR PERSONAL USE ONLY. I FEEL THAT THERE SHOULD BE A INVESTIGATION INTO THIS PROBLEM BECAUSE THIS WILL EFFECT MILLIONS OF GM TRUCKS. THIS PROBLEM WILL COST OVER $1000. TO FIX BECAUSE OF POSSIBLE FIRE,ENGINE FAILURE, EMISSIONS PROBLEMS, OTHER VERY COSTLY PROBLEMS THAT WILL RELATE TO THE BOLTS BREAKING OFF FROM DEFECT ON THE EXHAUST MANIFOLD. THIS CAN CAUSE VERY SERIOUS PROBLEMS. (THIS IS AS SERIOUS AS THE TOYOTA CAR PROBLEMS OR WORSE). I ALSO THINK WITH THE NEW AIR EMISSIONS STANDARDS THESE TRUCKS WILL NOT PASS THE INSPECTIONS. BECAUSE OF THE EXHAUST LEAKS ON THE MOTOR. THERE IS NO DOUBT I FEEL THIS SHOULD & CAN BE A CLASS ACTION SUIT. GM KNOWS OF THIS DEFECT OF THE BOLT BUT STILL NO RECALL. WHY MUST IT TAKE SOMEONE TO GET KILLED OR HURT BEFORE THEY FIX THE PROBLEM. I DON'T HAVE THOUSANDS TO FIX THIS PROBLEM & NOW WHEN I DRIVE I AM WORRIED ABOUT THE TRUCK GOING ON FIRE. GM MUST DO THE RIGHT THING TO CORRECT THE PROBLEM THE CAUSED. PLEASE KEEP ME INFORMED. THANK [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
