2008 VAN-CON CHEVY Engine And Engine Cooling Problems

I HAVE TAKEN THE VEHICLE TO THE SHOP. THEY SUGGEST REPLACING EGR VALVE AND CLEANING THE THROTTLE BODY. $210 TOTAL AND THEY ARE STILL TELLING ME THAT IT MIGHT FIX THE PROBLEM. I HAVE SEEN HUNDREDS OF POST BUT NO RESOLUTION TO THE TRACTION CONTROL LIGHT AND ABS LIGHT COMING ON. *TR

I HAVE MANY THINGS GOING ON. IT SURGES FORWARD WHEN I START IT, SERVICE AIR BAG LIGHT COMES ON/OFF. USES OIL AND ANTI-FREEZE. BACK BRAKES MAKES NOISE WHEN I BACKUP, LEAKS WATER THROUGH THE DRIVER DOOR. UNCONTROLABLE ON SNOW. FRONT TIRES ARE WEARING ON THE INSIDE. MY TRACTION CONTROL SEEMS TO BE ACTING UP. I BOUGHT IT WITH 48,000 MILES ON IT, AND IT HAS 53,000 MILES ON IT NOW. *TR

WHILE DRIVING OVER THE ROCKIES, PULLING A 5TH WHEEL, MY ENGINE BEGAN TO SMOKE BUT NOT HEAT UP. I PULLED OVER, LOOKED UNDER THE HOOD AND CALLED FOR HELP. THE FINDING WAS THAT THE FAN ASSEMBLY HAD COME LOOSE, BECAUSE OF A DEFECTIVE OR NEVER PROPERLY TIGHTENED BEARING, SENDING THE FAN FORWARD, DESTROYING THE SCHROUD WHICH THEN PUT A HUGE HOLE IN THE RADIATOR, EMPTYING IT. I OF COURSE NEEDED TO BE TOWED. I WAS TOLD BY THE DEALER THAT THIS IS NOT "UNCOMMON" AN YET THEY HAVE FAILED TO SHOW ME ANY PROOF OR EXPLAIN HOW THIS SHOULD EVER HAPPEN. IF IT IS INDEED COMMON FOR THE FAN TO LOOSEN ON A HUGE TRUCK, IT CERTAINLY SHOULD BE A RECALL ISSUE. THE INCIDENT WAS DESCRIBED AS A COOLANT LEAK TO CUSTOMER SERVICE. THIS OBVIOUSLY GOES WAY BEYOND A LEAK. I WAS OUT OF WARRANTY AND EVEN THOUGH THEY PROMISED...
