The contact had taken the vehicle to a local dealer where they were unable to service the vehicle. The contact had also taken the vehicle to an independent mechanic who informed him that there was a TSB placed on the vehicle. He explained that the incorrect type of transmission fluid had been placed in the transmission which would cause the failure that he had experienced. The contact then called Sewell Buick GMC of Dallas (7474 Lemmon Ave, Dallas, TX 75209) where he was informed that he would be charged a diagnostic fee prior to the repair. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 45,000.

All four OEM Bridgestone Dueler A/T P285/45R22 M+S tires are showing premature cracking in sidewall near the bead/wheel. The cracks appear on the full circumference of the tire and vary in length from short to several inches. Depth of cracking is estimated to be 1/16" and growing. The tires, with date code 2318, were on the brand new truck when purchased from the dealership in Aug 2018. The vehicle currently has 16k miles. Both the dealership and local Tires Plus chain have confirmed the issue, but there is not a suitable remedy. Bridgestone will not warranty the tires and replacement under the GM "warranty" is the same price as new aftermarket tires. I believe this is a pending safety concern.

I LEFT HOME TO GO TO THE STORE. WHILE DRIVING ON THE HIGHWAY MY SUNROOF EXPLODED. THERE WERE NO CARS OR TRUCK IN FRONT OF ME OR PASSING ME. NOTHING HIT MY TRUCK. IT SOUNDED LIKE A SHOTGUN GOING OFF INSIDE THE TRUCK. THE SUNROOF EXPLODED SENDING GLASS EVERYWHERE. I WAS DRIVING ON A 5 LANE HIGHWAY, IT WAS RAINING, BUT NOT A BAD STORM. THE ROAD WAS STRAIGHT AND IN GOOD CONDITION. IT HAPPENED SO FAST I DID NOT KNOW WHAT WAS GOING ON. I PULLED INTO A GAS STATION TO CHECK MY TRUCK. I FOUND GLASS ALL IN THE BED OF THE TRUCK AND MOST OF THE SUNROOF GONE. I HAVE TAKEN IT TO THE DEALER AS THE TRUCK IS UNDER WARRANTY. I WAS TOLD THE WARRANTY DOES NOT COVER DAMAGE AND SO FAR NO ANSWER IT THEY WILL COVER IT. I HAVE HAD THE TRUCK FOR ALMOST 3 YEARS AND IT IS NEARING THE END OF THE WARRANTY.
