WHILE DRIVING UP TO AN INTERSECTION I APPLIED THE BRAKES AND THE PEDAL DROPPED TO THE FLOOR, NO BRAKES. THE CROSS TRAFFIC WAS APPROACHING AT 50 MPH, AND MY ROAD STOPPED SO I HAD TO MAKE A LEFT OR RIGHT. LUCKILY, BY SOME MIRACLE THE ONCOMING TRAFFIC JUST MISSED SLAMMING INTO ME. I HAVE NEVER RECEIVED ANYTHING FROM GM ASKING FOR ME TO HAVE THE BRAKE LINES CHECKED, EVEN THOUGH I SEE ONLINE THAT I AM FAR FROM ALONE WITH THIS PROBLEM. I SEE YOU STARTED INVESTIGATING THIS ISSUE IN 2010 - WHY HAVEN'T YOU DONE ANYTHING ABOUT THIS? I WAS ALMOST KILLED AND NO ONE IS WARNING OWNERS OF GM TRUCKS I GUESS WHEN THE GOVERNMENT OWNS PART OF GM THEY DON"T HAVE TO WORRY ABOUT RECALLS....... THE CONSUMER STATED THE REASON THE BRAKES FAILED, WERE DUE TO RUSTED OUT BRAKE LINES.
