WHILE DRIVING 65 MPH AND PULLING A TRAILER VEHICLE STALLED. PRIOR TO STALLING THERE WAS SOME HESITATION AND JERKING AS IF NOT GETTING FUEL TO ENGINE. THE DEALER TOOK VEHICLE TO DEALERSHIP IN ARIZONA, AND FUEL PUMP HAD TO BE REPLACED. THIS WAS THE SECOND OCCURRENCE FOR FUEL PUMP PROBLEM. ALSO, EXPERIENCED STEERING PROBLEM. THE STEERING WOULD BE STICKING, AND IT WOULD JAM WHEN MAKING TURNS EITHER LEFT OR RIGHT. THE MECHANIC AT DEALERSHIP HAD TO REPLACE A SEAL IN COLUMN SHAFT OF STEERING WHEEL. *AK THE LIGHT CLUNK NOISE IN THE STEERING, LOW VOLTAGE, AND INSUFFICIENT FUEL PRESSURE ON ACELERATION INTERMITTENTLY. *SC

MY VEHICLE WAS REPAIRED ON 1-24-2013, AND SO FAR IT APPEARS THAT MY PROBLEM HAS BEEN RESOLVED, HOWEVER IT APPEARS GM IS NOT REALLY FIXING THE PROBLEM. I AM CONCERNED ABOUT THIS FOR THE NEXT OUT OF TOWN TRIP I TAKE. *TR
