2009 CHEVROLET SILVERADO Steering Problems

DRIVING ON I10 HEADING TO HOUSTON, THE ENTIRE TRUCK COMPLETELY SHUT DOWN, AND THEN TURNED BACK ON, THIS AGAIN HAPPENED 02/2014....THE WHOLE TRUCK SHUT DOWN , THANK GOD THE WHEELS DID NOT LOCK UP OR WE WOULD HAVE BEEN KILLED BOTH TIMES. IT IS AT THE DEALERS ...FREEDOM CHEVY SAN ANTONIO TX....SOMETHING IS BAD ON THE TRUCK...LIKE PLAYING WITH A LIGHT SWITCH...THE DASH, EVERY INSTRUMENT SHUT OFF BOTH TIMES, NOW I AM WORRIED THAT IT WILL HAPPEN AGAIN, AND I CAN NOT AFFORD ANOTHER TRUCK. I THOUGHT THAT THE 1ST TIME WAS JUST A FLUKE, BUT WHEN IT DID IT AGAIN, I KNOW NOW SOMETHING IS NOT RIGHT AND IS VERY DANGEROUS FOR ME AND MY LITTLE GIRL...PLEASE REPLY IF A HUMAN REALLY READS THIS. *TR
