THE BRAKES FAILED WHILE DRIVING ON A CITY STREET CAUSING MY VEHICLE TO NEARLY STRIKE A NUMBER OF CHILDREN AT A CROSSWALK. AFTER EXAMINATION BY A MECHANIC, IT WAS DETERMINED THAT THE BRAKE LINE HAD CORRODED AND BURST UNDER PRESSURE. I HAVE RECEIVED NO NOTICE OF THIS POTENTIAL FAILURE FROM GMC EVEN THOUGH IT HAS BEEN INVESTIGATED BY THE NHTSA. SHOULDN'T THE MANUFACTURER HAVE AN OBLIGATION TO REPAIR THIS POTENTIALLY LETHAL PROBLEM? AT A MINIMUM I FEEL THAT GMC AND/OR THE NHTSA HAVE A MORAL OBLIGATION TO NOTIFY OWNERS OF AFFECTED VEHICLES THAT THEY ARE DRIVING A POTENTIALLY DEADLY VEHICLE.
BRAKE FAILED WHEN APPLIED.MECHANIC SAID LINE IS RUSTED CAUSING LEAK. *JS
TOTAL BRAKE FAILURE, NO BRAKES. STEEL BRAKE LINE RUSTED THROUGH ON FRAME RAIL NEAR GAS TANK CAUSING FLUID CONTAINER TO EMPTY COMPLETELY. NO ADVANCED WARNING LAMP OR INDICATION OF FAILURE. TO REPLACE THE LINE, THE FUEL TANK MUST BE REMOVED. DEALER CHARGE $800.00 AND UP. *TR
I HAD A PANIC STOP WHILE DRIVING MY SUV, AND THE BRAKE PEDAL WENT TO THE FLOOR, OFFERING ALMOST NO BRAKING ABILITY. THIS CAUSED ME TO SHARPLY SWERVE AROUND THE CAR IN FRONT OF ME, DRIVE THROUGH A RED LIGHT AT A BUSY INTERSECTION INTO ONCOMING TRAFFIC, AND FIND A SAFE PLACE TO LAND.

I WAS DRIVING ON THE HIGHWAY AT APPROX. 60 MPH... WHEN ALL OF A SUDDEN I HEARD A CHIMING NOISE AND MY "SERVICE BRAKE SYSTEM" ALERT CAME ON! I THEN ATTEMPTED TO SLOW DOWN AND TO MY UNFORTUNATE DISCOVERY THE BRAKE PEDAL WENT STRAIGHT TO THE FLOOR. (SCARY) I LET THE VEHICLE COAST A BIT TO SLOW DOWN AND TRIED PUMPING MY BRAKES.. NOW PLEASE KEEP IN MIND I WAS DRIVING WITH MY 2 CHILDREN IN THE BACK SEAT. (SCARIER) I WAS ABLE TO SLOWLY STOP AND PULL OVER. I DISCOVERED THE REAR BRAKE LINE WAS LEAKING.. LONG STORY SHORT MY HUSBAND CAME AND WAS ABLE TO DRIVE IT HOME.. BUT BASICALLY BY THE GRACE OF GOD!!! I DID SOME RESEARCHING- CALLING A FEW DIFFERENT DEALERSHIP AND SERVICE LOCATIONS AND WAS TOLD IT WOULD COST ANYWHERE FROM $1,500 TO $600.00 TO HAVE THE LINES REPLACED,ECT. I AM FURIOUS THAT GM IS TRYING TO THROW THIS ON THE CONSUMER STATING THIS WAS A "MAINTENANCE ISSUE"... I HAVE READ NUMEROUS STORIES OF PEOPLE (REAL PEOPLE) HAVING THIS SAME PROBLEM, BUT GM WANTS TO SAY THIS IS OUT FAULT!!?!?!? NO WAY... IS THERE ANY RECOURSE? THANK GOD WE DID NOT HAVE AN ACCIDENT. *MY HUSBAND HAD A FRIEND OF HIS WHO WORKS ON VEHICLES TAKE A LOOK AND STATED THE LINES WERE COMPLETELY RUSTED AND CORRODED!!* *TR

I WAS DRIVING OUR 2003 GMC YUKON XL HOME AND THE BRAKES WENT THE FLOOR, LET ME TELL YOU THIS IS VERY SCARY ESPECIALLY WITH SUCH A LARGE VEHICLE. LUCKILY I WAS A BLOCK AWAY AND MADE IT HOME PUMPING THE BRAKES. THE BRAKE LINES BROKE JUST ABOVE THE REAR AXLE. BOTH LINES COME OUT OF A CONNECTOR AND THEY WERE VERY SEVERELY RUSTY, IT IS TOUGH TO SEE UNLESS YOU REMOVE THE SPARE TIRE. IF YOU LOOK AT THE SAME BRAKE LINES THAT RUN ACROSS THE REAR AXLE, THEY LOOK FINE. DON'T LET THAT FOOL YOU, THEY MAY BE VERY RUSTY UP FARTHER WHERE YOU CAN'T SEE. DOESN'T MAKE SENSE TO ME, BUT WE ALSO LOST OUR BRAKES WITH NO WARNING IN OUR 2002 GMC YUKON. THIS HAS HAPPENED WITH 2/2 GMC FROM 2002 AND 2003 THERE MUST BE MANY OTHERS AND ACCIDENTS FROM THIS HAPPENING, ITS A VERY FAST LOSS OF BRAKE FLUID WITH NO WARNING. GM HAS TO DO SOMETHING ABOUT THIS IF THEY WANT OUR BUSINESS AGAIN. *TR
