2011 GMC SIERRA Power Train Problems

FIRST OFF WOULD BE MY DASHBOARD AIR BAG, THE DASHBOARD PLASTIC IS CRACKING WITH THE CONCERN ON FLYING DEBRIS I BROUGHT MY GMC 1500 INTO MY LOCAL SERVICE/SALES CENTER AND HE TOLD ME WITH OUT A RECALL THERE IS NOTHING HE COULD DO FOR ME. SECOND I HAVE BEEN DEALING WITH WHAT SEEMS TO EITHER THE POWER TRAIN OR BRAKES FROM DAY ONE I PURCHASED MY TRUCK. WHAT IT DOES IS WHEN I COME TO A COMPLETE STOP, RELEASE THE BRAKE, AND THEN APPLY THE ACCELERATOR I GET A BIG CUR PLUNK SOUND AND FEELING OF THE TRUCK JERK. THIS IS COMING FOR THE REAR END OF MY TRUCK I WOULD ASSUME THE REAR AXIAL. I HAVE BROUGHT THIS UP TO MY LOCAL SERVICE/SALES CENTER , MULTIPLE TIMES.

WHY IS THIS DANGEROUS? I FOUND MYSELF IN A LEFT TURN ONLY LANE/GREEN LIGHT WITH OPPOSING TRAFFIC, AND I ATTEMPTED THE LEFT TURN WITH ONCOMING TRAFFIC BECAUSE I THOUGHT THAT I HAD AMPLE TIME BUT THE VEHICLE JUST SAT THERE FOR 1 - 2 SECONDS, AND WITH THAT I FOUND MYSELF IN A DANGEROUS PREDICAMENT BECAUSE THE ONCOMING TRAFFIC WAS GETTING VERY CLOSE.
