“SUBMISSION FROM CONSTITUENT RE GMC EXECUTIVE LETTER REPLY IN ENGINE STALLING/STOPPING WHILE BEING DRIVEN ON THE FREEWAY OF CALIFORNIA. *SMD THE CONSUMER STATED THE VEHICLE STALLED SEVERAL TIMES.

“EVERYTHING STARTED APRIL LAST YEAR AND ITS ONE THING AFTER ANOTHER SINCE. FIRST MY ENGINE STARTED STALLING, WHILE DRIVING. ONE INCIDENT, I LOST HALF A TANK OF GAS WITHIN A 15 MINUTE RIDE, WHICH I HAVE A 17 GALLON TANK. THEN WHILE DRIVING ON AN EXPRESSWAY, IT SUDDENLY DROPPED FROM 70 TO 20 BEFORE I COULD GET OVER TWO LANES TO GET OUT OF THE WAY OF TRAFFIC. IVE CLEANED THE THROTTLE BODY, IVE CLEANED THE CAMSHAFT ACTUATOR, IVE REPLACED THE AIR FILTER, FUEL FILTER, AND THE OIL TWICE WITHIN A 8 MONTH PERIOD, AND YET IT STILL CONTINUES TO STALL. NOW I RECENTLY CHANGE THE WATER PUMP TO SEE IF THAT WOULD HELP, EVEN THOUGH MY CAR WAS NOT OVER HEATING, NOW ITS STALLING EVEN WORSE; I CANT EVEN MAKE IT THROUGH A DRIVE THROUGH WITHOUT HAVING TO START IT TWICE. SECOND AND EVEN SCARRIER ISSUE, I HIT POT HOLE ONE DAY AND BEFORE I COULD MAKE 15 MILES, I HEARD GRINDING. A CV JOINT HAD TO BE REPLACED, THEN TWO DAYS AFTER THAT THE OTHER CV JOINT BROKE OFF AND BROKE MY FRONT AXLE DISCONNECT ASSEMBLY. DID I HIT ANYBODY? NO THANK GOD I WAS IN THE RIGHT HAND LANE AND COULD GET OVER WITHOUT HITTING ANYONE OR CAUSING INJURY TO MYSELF. IVE REPLACED BOTH CV JOINTS AND THE ASSEMBLY NOW AND…”

“WHEN I START THE TRUCK IN THE MORNING IT SOUNDS LIKE THE ENGINE IS REVVED UP WITH THE LOUD FAN NOISE. I HAD THE FAN CLUTCH REPLACED INDEPENDENTLY AND THE LOUD NOISE CONTINUES AND A SLIGHT LOSS OF POWER AT TIMES WHILE DRIVING AND IT FEELS LIKE IT'S TAKING TOO LONG SHIFT INTO THE NEXT GEAR. THE NOISE IS REALLY HEARD WHEN YOU ACCELERATE ON THE GAS PEDAL. *TR”
