I OWN A 2006 GMC SIERRA. I PURCHASED THIS VEHICLE FROM A RELATIVE (70 YEAR OLD WOMAN) AND IT HAS 22,000 MILES ON IT. I HAVE JUST HAD A MECHANICAL ISSUE BEGIN. WHEN SLOWING THE VEHICLE TO APPROXIMATELY 5 MPH, THE VEHICLE ABS ACTIVATES AND THE TRUCK THRUSTS FORWARD. I WAS ADVISED BY A MECHANIC THAT THIS IS A FAILURE OF BOTH FRONT WHEEL HUB ASSEMBLIES. BECAUSE THIS VEHICLE HAS SO FEW MILES ON IT I BEGAN LOOKING ON LINE FOR RECALL INFORMATION. I AM SHOCK HOW MANY PEOPLE HAVE ALSO EXPERIENCED PROBLEMS AROUND 20,000 MILES, SOME RESULTING IN CRASHES. I ALSO LEARNED THAT THE COMPANY THAT MANUFACTURES THE HUB ASSEMBLIES HAS ISSUED A RECALL FOR THE PARTS UNLESS IT WAS INSTALLED BY THE FACTORY (GM). THIS ISN'T RIGHT AND SOMEONE WILL GET INJURED BADLY. GM SHOULD RECALL THE VEHICLE. *TR
