2011 TOYOTA TUNDRA Wheels Problems

THE TUNDRA IS A 2011 AND THE REAR DRIVER SIDE WHEEL HAS BEEN THE ISSUE. I WAS ON A CITY STREET ABOUT 2AM WHEN A LOUD CRASH AND THUNDERING MADE DRIVING VERY HARD. THE REAR WHEEL HAD SHEARED OFF AND WAS PASSING ME BY AS I SLOWED DOWN SPARKS FLYING LIKE THE FOURTH OF JULY!! I HAD BEEN GOING 25 MILES AN HOUR IN A RESIDENTIAL SETTING. I HAD THE TRUCK TOWED TO THE DEALER WHOM AGREED THIS WAS AN OBSCURE OCCURRENCE, TO WHICH THEY WARRANTIED AND FIXED IT. THIS OCCURRED AT 250,000 MILES SO THAT SEEMED LIKE A SATISFACTORY ENDING! HOWEVER, AT 3500 MILES LATER GOING 70MPH DOWN INTERSTATE 20 AT 4 AM A HORRENDOUS CRASH ( NOISE) AND ALMOST FLIPPING THE SAME TIRE SHEARED AGAIN PASSING ME BY!! I WAS LUCKY THAT I DIDNT FLIP!
