I WAS MOVING THE VEHICLE IN THE DRIVEWAY WHEN THE BREAK PEDAL WENT TO THE FLOOR. THE TRUCK STOPPED SO I GOT OUT AND LOOKED UNDER IT AND SAW BREAK FLUID POURING OUT OF A BREAK LINE THAT HAD COMPLETELY RUSTED THROUGH. THE FORMER OWNER HAD ALREADY HAD ANOTHER BREAK LINE REPLACED BECAUSE HIS BREAKS HAD RUPTURED DUE TO THE LINES RUSTING THROUGH WHILE DRIVING AT HIGHWAY SPEEDS AND TOWING A FIFTH WHEEL CAMPER. HE WAS ABLE TO AVOID WRECKING AND CAME TO A STOP. THIS TRUCK HAS LOW MILES AND ABOUT 90% OF ITS USE HAS BEEN DURING THE SUMMER SO IT HAS HAD LIMITED CONTACT WITH SALTED ROADS YET THE ENTIRE UNDERCARRIAGE OF THE VEHICLE IS RUSTING AT AN INCREDIBLE RATE. I AM FORTUNATE THAT I WAS SIMPLY MOVING THE TRUCK RATHER THAN HAULING MY CAMPER ON THE HIGHWAY WHICH IS IT'S TYPICAL USE; I AND/OR OTHERS COULD HAVE BEEN SEVERELY INJURED OR KILLED. THE RUSTING THROUGH OF THE BREAK LINES IS A SAFETY ISSUE!

DRIVING TO WORK ONE DAY, A CAR IN FRONT OF ME SUDDENLY STOPPED TO TURN LEFT. I HIT MY BRAKES AND FELT A "POP" AND THE BRAKE PEDDLE WENT STRAIGHT TO THE FLOOR, NO BRAKES. I WAS TRAVELING ABOUT 55 MPH SO AT THAT POINT, I AM A 55 MPH SPEAR ON WHEELS. I SWERVED TO THE RIGHT AND DROVE ACROSS SOMEONE'S DRIVEWAY AND THROUGH THEIR YARD. THIS WEEKEND WAS THE CITY WIDE GARAGE SALES, AND THANKFULLY, THESE FOLKS WERE NOT HAVING A SALE IN THEIR DRIVEWAY OR YARD, OR ELSE THIS COULD HAVE BEEN A TERRIBLE ACCIDENT. THE ONLY RUST ISSUE WITH THIS TRUCK IS THE BRAKE LINES AND FUEL LINES. IF YOUR LINES RUST BEFORE YOUR BODY RUST, THEN I FEEL THERE IS A SERIOUS DESIGN FLAW. IF IT WAS SOMETHING ELSE RUSTING THEN IT WOULDN'T BE AS BIG OF A DEAL. BUT WHEN YOU ARE TALKING BRAKE LINES, IT IS JUST A MATTER OF TIME BEFORE THIS FLAW CAUSES ANOTHER CATASTROPHIC BRAKE FAILURE, LEADING TO AN ACCIDENT INVOLVING SERIOUS INJURY OR DEATH. A 10 YEAR OLD TRUCK SHOULD NOT HAVE THIS PROBLEM. I HAVE OWNED VEHICLES THAT WERE 15, 20 YEARS OLD AND HAVE NEVER HAD TO REPLACE BRAKE LINES. SOMEONE'S LIFE IS WORTH SO MUCH MORE THAN A CHEAPLY MADE BRAKE LINE. *TR

I WAS DRIVING MY 03 SIERRA, APPROACHING A STOPLIGHT AT A BUSY INTERSECTION WHEN I APPLIED THE BRAKES. THE TRUCK BEGAN TO SLOW AT FIRST BUT THEN THE PEDDLE IMMEDIATELY WENT COMPLETELY TO THE FLOOR. I BEGAN TO PUMP IT BUT THERE WAS NO RESPONSE. I WAS HEADING TOWARD THE INTERSECTION, THE LIGHT WAS RED, WITH BUSY CROSS TRAFFIC. THE STREET I WAS ON IS NARROW AND STEEP AND I BEGAN TO PICK UP SPEED. I SHIFTED THE TRANS INTO THE LOWEST GEAR AND STEPPED ON THE EMERGENCY BRAKE. THE TRUCK FINALLY CAME TO A STOP IN THE MIDDLE OF THE INTERSECTION, AS ONCOMING CARS LUCKILY AVOIDED HITTING ME. WHEN I WENT TO MY MECHANIC TO ARRANGE TO HAVE THE TRUCK TOWED, HE KNEW IMMEDIATELY WHAT THE PROBLEM WAS. HE TOLD ME, SIGHT UNSEEN, THAT THE BRAKE LINE UNDER THE DRIVER'S SIDE HAD RUPTURED. LATER, UPON INSPECTION, HE WAS CORRECT. HE ALSO TOLD ME THAT THIS WAS A VERY COMMON PROBLEM WITH THAT YEAR. HE REPLACED THE LINE AND I THOUGHT THAT HAD SOLVED THE PROBLEM; UNTIL TWO DAYS AGO. AGAIN, I AM DRIVING DOWN A HILL AND THE SAME THING HAPPENED. I WAS TOWING A VERY LARGE TRAILER THIS TIME AND THE EMERGENCY BRAKE HAD LITTLE AFFECT. LUCKILY, THERE WAS LITTLE TRAFFIC AND I WAS ABLE TO RIDE IT OUT WITHOUT INCIDENT. I HAVE SINCE DISCOVERED THAT THIS IS A PROBLEM WITH NOT ONLY THE 03 YEAR BUT 4 OR 5 YEARS PRIOR ALSO. ANOTHER MECHANIC TOLD ME THAT THE ENTIRE SYSTEM OF LINES SHOULD BE REPLACED SINCE GM USED A UNCOATED STEEL WHICH BEGINS TO BE COMPROMISED WITHIN JUST A FEW YEARS WHERE SALT IS HEAVILY USED IN THIS AREA. IT IS OBVIOUS THAT GM USED UNCOATED STEEL INSTEAD OF COATED OR STAINLESS TO SAVE A FEW DOLLARS. HAD MY 17 YEAR OLD SON BEEN DRIVING, THE OUTCOME COULD HAVE BEEN DISASTROUS. THIS IS ONLY ONE OF MANY PROBLEMS I HAVE HAD WITH THIS TRUCK. ANOTHER IS ERRONEOUS SPEEDOMETER READINGS. I WILL ADDRESS THESE IN ANOTHER POST. *TR

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.

AS I BEGAN BACKING OUT OF MY DRIVE WAY MY BRAKE PEDDLE WENT TO THE FLOOR AND I HAD A RAPID DECREASE IN BRAKING POWER. UPON INVESTIGATION I NOTICED BRAKE FLUID LEAKING FROM THE BRAKE LINES RIGHT ABOVE THE FRAME RAIL ON THE DRIVER SIDE. IF THIS HAPPENED WHILE DRIVING IT COULD HAVE LED TO INJURIES OR FATALITIES ESPECIALLY WHEN SUCH A LARGE AND HEAVY TRUCK SUDDENLY LOSES BRAKING POWER. *TR

WAS DRIVING DOWN ROAD AT SPEED LIMIT, HIT BRAKES, REAR BRAKE LINE BURST (WAS SEVERELY RUSTED). I WAS UNABLE TO STOP VEHICLE AND PROCEEDED THROUGH A RED LIGHT AT A BUSY INTERSECTION WITH MY 2 YEAR OLD ON BOARD IN HIS CAR SEAT. HOW WE BOTH MADE IT OUT OF THAT INCIDENT UNSCATHED IS AMAZING. I WAS UNABLE TO STOP AND HAD TO PULL OFF TO THE SHOULDER AND HIT THE PARKING BRAKE. IT TOOK MY SON A GOOD 2 MONTHS BEFORE HE WAS ABLE TO RID HIMSELF OF FEAR AND ANXIETY DUE TO WHAT HAPPENED. *TR
