NHTSA Complaint #10217735 — 2007 CHEVROLET SILVERADO 2500

I HAVE TAKEN MY 2007 CHEVY SILVERADO 2500HD CREW CAB IN TO THE DEALER MANY TIMES, THEY HAVE FIXED THE PROBLEM A FEW TIMES THEN PROCEED TO SAY IT IS NORMAL FOR IT TO DO WHAT IT DOES. THE FRONT TIRES TURN IN TOWARDS EACH OTHER WHEN IT IS IN FOUR WHEEL DRIVE, AND CAUSES THE TRUCK TO DRIFT OFF WHERE IT WANTS TO. I HAVE TAKEN IT IN TO MEROLLIS CHEVY MANY TIMES, THEY HAVE FIXED IT A FEW THEN JUST TELL ME ITS NORMAL. FRIDAY FEB 8 2008 I GOT MY TRUCK BACK FROM MORAN CHEVY AFTER 2 DAYS BEING IN THE SHOP, AND THEY SAID EVERYTHING WAS GOOD LATER THAT DAY WHEN I HAD TO USE FOUR WHEEL DRIVE I HAD THE SAME PROBLEM BUT WORSE THAN WHEN I TOOK IT IN, THE PROBLEM WAS NOT FIXED SATURDAY AS I WAS DRIVING HOME THE ROADS WHERE BAD AND I PUT THE TRUCK INTO 4 WHEEL DRIVE THINKING IT WOULD BE SAFE SINCE THEY STATED THEY FIXED IT, IT WASN'T. AS I WAS GETTING ON THE FREE WAY THE TRUCK STARTED TO DRIFT OUT OF CONTROL AND SLAMMED INTO THE MEDIAN ON THE FREE WAY. THE FIRST TIME I EVER TOOK THE TRUCK IN FOR THIS PROBLEM IT ONLY HAD 371 MILES ON IT. IT HAS BEEN NOTHING BUT PROBLEMS EVER SINCE THEN. *TR
