EXHAUST BOLTS HAVE BROKEN ON THE EXHAUST MANIFOLD, THIS VEHICLE HAS THE V8 ENGINE. DEALER EXPLAINS THAT THIS NEEDS FIXED AS CARBON MONOXIDE COULD ENTER THE PASSENGER CABIN. THERE WAS AN ACCIDENT WITH THE VEHICLE A YEAR AGO, I CONTACTED MY INSURANCE COMPANY TO SEE IF IT WAS RELATED TO THE ACCIDENT. THEY CLAIM THAT IT IS NOT RELATED TO THE ACCIDENT AND THAT GM VEHICLES MODEL YEAR 2000 TO 2007 WITH THIS 5.3 V8 ENGINE HAVE REPORTED THESE BOLTS BREAKING AND INFORMED ME TO CONTACT GM ABOUT REIMBURSEMENT FOR REPAIR EXPENSES. I DO NOT HAVE THE $2000 FOR REPAIRS AND AM CONCERNED ABOUT THE SAFETY OF MY FAMILY WHILE IN THE VEHICLE. *TR

THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
