2015 CHEVROLET SILVERADO HD Steering Problems

NEW TRUCK, 15372 MILES, NO OFF ROADING OR ROUGH SURFACE DRIVING. PULLS TO THE RIGHT. CONCERNED ABOUT SUSPENSION/STEERING FAILURE. THE VEHICLE PULLS TO THE RIGHT. TWO CHEVY DEALERS HAVE LOOKED AT THE ISSUE WITH NEGATIVE RESULTS. THERE IS NO REASON OTHER THAN MANUFACTURING ERROR THAT WOULD CAUSE THE PROBLEM. BOTH CHEVY DEALERS HAVE REPORTED THAT THE TIRES ARE IN GOOD CONDITION AND ONE DID AN ALIGNMENT. THE ALIGNMENT,I PAID FOR,DID NOT RESOLVE THE ISSUE. I AM CONCERNED BECAUSE I USE THE VEHICLE TO PULL A TRAVEL TRAILER AS IT IS DESIGNED FOR. CHEVY,IN MY OPINION, IS NOT RESPONSIVE TO MY CONCERNS. I AM CONCERNED ABOUT LOOSING THE ABILITY TO CONTROL/STEER THE VEHICLE IF THE UNIDENTIFIED ISSUE IS NOT DISCOVERED OR RESOLVED BY CHEVY. I PROPOSE THAT DEFECTIVE PARTS,OR TIRES HAVE BEEN USED ON THE VEHICLE WHEN BUILT AND THEY ARE FAILING. SINCERELY THE CONSUMER STATED THE VEHICLE PULLED THE RIGHT....
