2002 GMC Yukon Xl Denali Brakes Problems

I WAS DRIVING ON 58 WEST IN STUART VA WHEN WE CAME AROUND A CURVE AND AN 18 WHEELER WAS BROKEN DOWN IN THE MIDDLE OF OUR LANE. TWO VEHICLES WERE STOPPED BEHIND THE TRUCK. I QUICKLY APPLIED THE BRAKES AND THE PEDAL WENT TO THE FLOOR. I WAS ABLE TO MANEUVER BETWEEN THE STOPPED TRAFFIC AND THE ONCOMING VEHICLE IN THE OPPOSING LANE TO AVOID A CRASH. A BRAKE LINE HAD BLOWN CAUSING THE BRAKE FAILURE. I HAD ALREADY EXPERIENCED BRAKE FAILURE IN ANOTHER GM MODEL, AND WAS QUESTIONING HOW IT WAS POSSIBLE THAT ONE PERSON COULD HAVE TWO SEPARATE BRAKE LINE FAILURES ON TWO SEPARATE BUT SIMILAR VEHICLES. AS I RESEARCHED IT BECAME CLEAR THAT THIS TYPE OF BRAKE FAILURE WAS COMMON ON THESE TYPES OF VEHICLES. I'VE LIVED IN SOUTHWEST VIRGINIA MY ENTIRE LIFE, AND I HAVE OWNED 30-40 VEHICLES OF ALL MAKES AND MODELS, BUT I HAVE ONLY EXPERIENCED NEAR CATASTROPHIC VEHICLE FAILURE ON TWO OF THOSE VEHICLES, A 2001 CHEVROLET SUBURBAN AND A 2002 GMC YUKON. TO SAY THAT THESE BRAKE LINE FAILURES COULD BE AVOIDED THROUGH ROUTINE MAINTENANCE IS A BRAZEN ATTEMPT TO DEFLECT CULPABILITY TOWARDS A CONSUMER MARKET NEITHER DESIGNED NOR EQUIPPED TO DIAGNOSE PENDING FAILURE WITHOUT WARNING. THESE VEHICLES HAVE INNUMERABLE SENSORS TO INDICATE ALL TYPES OF OF POTENTIAL ISSUES, EVEN SO FAR AS TO REMIND THE DRIVER WHEN THE OIL NEEDS TO BE CHANGED. IF THE MANUFACTURER FEELS THE OWNER IS SO INEPT AS TO TRACK OIL CHANGES EVERY THREE THOUSAND MILES, HOW ON EARTH DO THEY EXPECT THOSE SAME PEOPLE WOULD BE ABLE TO DIAGNOSE THE DEGRADATION OF BRAKE LINES, MOST OF WHICH ARE HIDDEN? I'VE NEVER BEEN TO A SHOP AND BEEN ASKED AS PART OF THE MANY SERVICES THEY OFFER, INCLUDING STATE SAFETY INSPECTIONS, "WOULD YOU LIKE US TO TEST YOUR BRAKE LINES FOR POTENTIAL FAILURE?" CV AXLES, BALL JOINTS, BRAKE PADS, ALL ARE INCLUDED IN INSPECTIONS. NOT BRAKE LINES, BECAUSE THEY ARE NOT MAINTENANCE PARTS. GM IS WHOLLY RESPONSIBLE.

WHILE UNDER VEHICLE TO REPLACE GAS FILTER IT HAD BECOME EVIDENT TO ME THAT THE BRAKE LINES WHERE THEY ENTER THE ABS UNIT WERE FAIRLY RUSTED. AS I INVESTIGATED FURTHER TO AREAS NOT EASILY VISIBLE I HAD DISCOVERED THAT ALL THE HYDRAULIC BRAKE LINES ARE EXTREMELY RUSTED AND IMMINENT FAILURE IS EVIDENT. IN MENTIONING THIS TO A FRIEND HE SUGGEST I CHECK ON LINE AS HE HAD HEARD OF THIS PROBLEM. I WAS ABSOLUTELY TAKEN ABACK TO SEE HOW COMMON THIS FAILURE IS ON THESE VEHICLES AND THAT GMC IS AWARE OF IT, YET THEY HAVE NEVER APPRISED ME OF THIS "POSSIBLE CONDITION"' AND THAT I SHOULD TAKE NECESSARY ACTION TO PREVENT FAILURE WHICH COULD RESULT IN SERIOUS INJURY OR DEATH ! I HAVE BEEN A MECHANIC FOR MANY YEARS AND HAD WORKED FOR GM SOME YEARS BACK. I HAVE NEVER OBSERVED SUCH DETERIORATION IN A VEHICLE OF THIS AGE. THIS VEHICLE IS EXTREMELY WELL MAINTAINED IN BOTH PERIODIC AND PREVENTATIVE MAINTENANCE. I DO NOT LIVE BY THE WATER, WE LIVE IN A MODERATE CLIMATE AND VEHICLE IS NOT SUBJECT TO ANYTHING BUT NORMAL DRIVING CONDITIONS. I HAVE (COLLECTIBLE VINTAGE CARS) OLDEST BEING 36 YEARS OLD AND THE LINES ON ALL CARS LOOK NEW OR IN GOOD SHAPE. TO MY FURTHER DISSATISFACTION I HAD CONTACTED GMC AND THEY DENY ANY KNOWLEDGE OF THIS PROBLEM OR CONDITION. I THINK ALL PARTIES CONCERNED SHOULD CONSIDER THE POSSIBLE CATASTROPHIC OUTCOME OF THIS COMPONENT FAILURE AND ALSO TAKE INTO ACCOUNT THE SIZE AND WEIGHT OF THESE VEHICLES AND THE POSSIBLE SECONDARY CONSEQUENCES IN AN ACCIDENT AND TAKE IMMEDIATE REMEDIAL ACTION. *TR

I RECENTLY EXPERIENCED A TOTAL BRAKE FAILURE AFTER DRIVING TO THE GROCERY STORE TODAY. YESTERDAY, I REALIZED THAT TO STOP, I HAD TO PRESS THE BRAKE PEDAL ALMOST ALL THE WAY TO THE FLOOR. I KNEW SOMETHING WAS WRONG BECAUSE MY BRAKES HAD BEEN WORKING JUST FINE. TODAY I NOTICED THE SAME PROBLEM AND REPORTED IT TO MY BOYFRIEND, WHO CONDUCTED A VISUAL INSPECTION AT THE BRAKE LINES AND UNDERNEATH THE DRIVER SIDE SEAT, BRAKE FLUID WAS LEAKING OUT RAPIDLY AND WAS PUDDLING UNDERNEATH THE VEHICLE. HAD I NOT STOPPED, I WOULD HAVE BEEN IN A SERIOUS ACCIDENT. AS A RESULT, I CAN NOT DRIVE MY VEHICLE BECAUSE THE BRAKES ARE NO LONGER WORKING. I HAVE A 2002 GMC YUKON DENALI XL. *TR

DEALER WAS VERY UNCOOPERATIVE IN SEEKING GM REMEDIATION ASSISTANCE FOR US OR TAKING ANY SELF-INITIATIVE ANYTIME TO KEEP US INFORMED, VEHICLE OUT OF SERVICE & HAS BEEN AT DEALER FOR GOING ON 3 DAYS NOW, AFTER NOT FOLLOWING UP WITH US NOR RETURNING OUR CALLS JUST REACHED DEALER RIGHT BEFORE CLOSING TIME & WAS INFORMED THEY STILL CANNOT LOCATE PARTS AT FACTORY OR ANYWHERE ELSE, FACT THAT 4 LINES DEFECTIVE SIMULTANEOUSLY & STILL UNABLE TO LOCATE PARTS CLEARLY INDICATES MANUFACTURING DEFECT...

AFTER TWO PREVIOUS "REPAIRS" (ONE A RECALL), OUR GMC ABS BRAKES ARE NOW MALFUNCTIONING FOR THE THIRD TIME. THE ABS BRAKE SYSTEM ACTIVATES ON DRY PAVEMENT AT SLOW SPEEDS, RESULTING IN A LONGER THAN NORMAL STOPPING DISTANCE. ON NUMEROUS OCCASIONS, COLLISIONS HAVE NARROWLY BEEN AVOIDED AS THE ABS BRAKE PEDAL "CHATTERING" PREVENTS NORMAL BRAKING AT CRUCIAL TIMES. *TR
