2015 Gmc Sierra 1500 Wheels Problems

I RECENTLY PURCHASED A GMC SIERRA 1500 FROM CARMAX FITTED WITH A SET OF CROSSCONTACT LX20'S. THE TRUCK HAD ABOUT 18,000 MILES OR FEWER WHEN I BOUGHT IT AND IT NOW HAS 31,000 MILES ON IT. THE TWO FRONT TIRES STARTED TO DISINTEGRATE AROUND 28,000 MILES AND NOW HAVE BECOME UNSAFE AND UNUSABLE. I CONTACTED YOUR CUSTOMER SUPPORT OFFICE AND WAS TOLD THAT THEY COULD NOT DO ANYTHING FOR ME AS I WAS THE SECOND OWNER AND I SHOULD CONTACT CARMAX. OF COURSE CARMAX SAYS, CALL CONTINENTAL. THE CODE ON ALL 4 OF MY TIRES IS A32A WBDE 2215. I HAVE ENCLOSED A FEW PHOTOS OF THE FRONT TIRES, THE BACK TIRES ARE SHOWING THE SAME SEPARATION FROM THE STEEL BELT, BUT NONE OF THE TREAD HAS COME OFF YET. I BELIEVE THE TURNING BACK AND FORTH OF THE FRONT TIRES HAS ACCELERATED THEIR DEMISE. I HAVE PURCHASED 4 NEW GOODYEAR TIRES BECAUSE I TRULY FEAR FOR MY FAMILIES SAFETY. I WOULD APPRECIATE YOUR TIME AND CONSIDERATION IN THIS MATTER.

BOUGHT SET OF FOUR DYNAPRO HT P255 70R17 TIRES. HAD TO TAKE THEM IN FOR RE-BALANCING THREE TIMES DUE TO ROUGH BUMPY RIDE. THIRD RE-BALANCING WAS TO A DIFFERENT DEALER THAN THE ORIGINAL SELLER. HE SAID TIRES WERE BADLY "OUT OF ROUND". ORIGINAL DEALER REPLACED TIRES WITH MICHELIN. HAD TO HAVE THESE TIRES 'ROAD FORCE BALANCED' AND PROBLEM WAS SOLVED.

TRUCK SHAKES AT HI-WAY SPEED. REPLACED TIRES AS TOLD BY DEALER AND ROAD FORCE BALANCE AND HAD NO EFFECT ON THE SHAKING.

WITHIN ONE YEAR OF PURCHASING THIS VEHICLE, AND OCCURRING NUMEROUS TIMES OVER THE COURSE OF 15,000 MILES, THIS VEHICLE SUDDENLY AND WITHOUT WARNING COMPLETELY LOST CONTROL IN WET CONDITIONS. VEHICLE WAS ALWAYS OPERATED WITH ALL SAFETY MECHANISMS INCLUDING TRACTION CONTROL ON. VEHICLE WAS ALWAYS OPERATED AT OR BELOW THE POSTED SPEED LIMITS AND WELL BELOW SPEED LIMITS IN WET CONDITIONS. ACCELERATING FROM A STOP AND TURNING ONTO ROADS EITHER FROM A STOP SIGN OR RED LIGHT, THE VEHICLE REPEATEDLY SPUN 90 TO 180 DEGREES FOR NO REASON. THE VEHICLE ALSO ON SEVERAL OCCASIONS COMPLETELY LOST CONTROL LATERALLY AND SLID SIDEWAYS AS IF ON ICE; SOMETIMES IN TRAFFIC AND FORTUNATELY NO DAMAGE OR INJURY OCCURRING. VEHICLE HAS BEEN TO THE DEALER WITH TIRES AND SUSPENSION FOUND TO BE WITHIN LIMITS. SINCE NO INDIVIDUAL COMPONENT WAS DEFECTIVE EITHER THE VEHICLE, TIRES, OR THE COMBINATION MUST BE INTRINSICALLY UNSAFE. GM CUSTOMER CARE WAS CONTACTED AND CASE [XXX] OPENED. GM WILL NOT PERFORM ANY ACTION OR REPLACE TIRES SINCE THEY CANNOT DUPLICATE THE LOSS OF CONTROL ON DRY ROADS. GM'S OFFICIAL RESPONSE TO ME WAS TO TAKE THE VEHICLE TO THE DEALER DURING A RAIN STORM AND WITH ONE OF THEIR TECHS IN THE VEHICLE, I WAS TO REPLICATE MY PROBLEM FOR THEM TO WITNESS. GM'S OFFICIAL RESPONSE TO ME, INCLUDING CUSTOMER CARE CONSULTANT AND DEALER SERVICE MANAGER WORKING THROUGH HIS DISTRICT MANAGER, WAS TO INTENTIONALLY MAKE THE VEHICLE LOSE CONTROL ON A PUBLIC ROAD. THIS SEEMS COMPLETELY IRRESPONSIBLE AND POTENTIALLY CRIMINALLY TO ME SHOULD ANY PROPERTY DAMAGE OR INJURY OCCUR AS A RESULT. I HAVE REPLACED THE TIRES AT MY OWN EXPENSE OF NEARLY $1000 ON A NEARLY NEW $50K+ TRUCK IN ORDER TO DRIVE SAFELY.
