WHEN COMING UP TO AN INTERSECTION, THE TRUCK FAILED TO COME TO A COMPLETE STOP, IN DRY CONDITIONS, WITH AMPLE STOPPING DISTANCE. THE TRUCK WAS REVVING AT A HIGH RPM, AND CONTINUED TO PUSH FORWARD WITH THE BRAKE PEDAL PUSHED AS HARD AS POSSIBLE. THIS RESULTED IN A ROLLING COLLISION. VEHICLE FINALLY STOPPED WHEN SHIFTED INTO PARK. IMMEDIATELY CALLED DEALERSHIP, AND GM. AFTER 2 DAYS IN THE DEALERSHIP THEY STATED NOTHING IS WRONG, AND WILL NOT INVESTIGATE ANY FURTHER. I WILL NOT DRIVE THE VEHICLE ANY LONGER AFTER THIS SCARY INCIDENT.*JB
