2004 GMC Sierra

I WAS I 91 SOUTH HEADING IN TO HARTFORD CT, TRAFFIC WAS HEAVY AND AS A RESULT I WAS TRAVELING APPX 20 MPH AS I ENTERED THE RAMP EXIT LANE. I STEPPED ON BRAKE PEDAL AND THE PEDAL WENT TO THE FLOOR, FORTUNATELY I WAS ABLE TO VEER INTO THE BREAKDOWN LANE AND AVOID HITTING OTHER CARS. I SLOWLY MADE IT TO MY PLACE OF EMPLOYMENT AND LATER HAD THE TRUCK TOWED HOME. AS IT TURNS OUT I DISCOVERED THE ALL BRAKE LINES HAD CORRODED AND HAD TO BE REPLACED. I CONTACTED GM AS I THOUGHT IT VERY UNUSUAL FOR ALL BRAKES LINES TO BE SO SEVERELY CORRODED. THEY ATTRIBUTED THE SEVERE CORROSION TO THE FACT THAT THE TRUCK WAS 10 YEARS OLD AND REFUSED TO COVER THE EXPENSE AND CONSIDERED THE CASE CLOSED. BY DOING A SIMPLE INTERNET SEARCH I FOUND THAT THIS SAME PROBLEM IS QUITE COMMON AND MY MECHANIC ALSO INFORMED THAT GM ( POSSIBLY AS A RESULT OF THIS BEING A COMMON ISSUE) HAS MADE A AVAILABLE A BRAKE LINE REPLACEMENT KIT. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT STATED THAT WHILE REVERSING INTO HER RESIDENTIAL GARAGE, THE BRAKES FAILED. THE CONTACT MENTIONED THAT AFTER INSPECTING THE VEHICLE, SHE NOTICED THAT ONE OF THE BRAKE LINES HAD FRACTURED AND ALL THE REST OF THE BRAKE LINES WERE COMPLETELY CORRODED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 78,000.

AFTER EXITING ONTO THE HIGHWAY AND ATTEMPTING TO BRAKE TO MAKE A RIGHT TURN I EXPERIENCED CATASTROPHIC BRAKE FAILURE. WHEN THE BRAKE PEDAL WAS APPLIED THERE WAS NO PRESSURE, AND THE PEDAL WENT STRAIGHT TO THE FLOOR. NO WARNING LIGHTS OR SENSORS WERE ACTIVATED BEFORE THE TOTAL BRAKE FAILURE. THE VEHICLE WAS TOWED TO A LOCAL GMC DEALERSHIP. THE DEALERSHIP ADVISED ME THAT THE BRAKE LINE "BLEW OUT" FROM THE FRONT LEFT CALIPER BECAUSE OF RUST. I RESEARCHED SUCH PROBLEMS AND FOUND THAT SIMILAR COMPLAINTS WERE NUMEROUS AND THAT THE NHTSA HAD INITIATED AN INQUIRY/INVESTIGATIONS INTO EXCESSIVE RUST ON BRAKE COMPONENTS OF GMC VEHICLES CAUSING THIS TYPE OF TOTAL BRAKE FAILURE. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME STUCK TO THE FLOOR BOARD. THE VEHICLE WAS TOWED TO THE DEALER, WHO INSPECTED THE VEHICLE AND FOUND THAT THE REAR BRAKE LINE WAS LEAKING DUE TO CORROSION. THE REAR BRAKE LINE WAS REPLACED. THE MANUFACTURER WAS NOT AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 97,047 AND THE APPROXIMATE FAILURE MILEAGE WAS 99,000. UPDATED 11-04-13 *BF UPDATED 11/8/2013 *JS

VEHICLE IN FRONT OF ME STOPPED SUDDENLY. MY BRAKES FAILED AS MY FOOT/PEDAL HIT THE FLOOR. ALL I HEARD WAS BUZZING. I HIT THE VEHICLE IN FRONT OF ME. MECHANIC SHOWED ME THE RUSTED OUT BRAKE LINE THAT FAILED. ADVISED ME THAT THE ABS PUMP JUST PLAN EMPTIED MY MC TO MAKE UP PRESSURE LOSS. MY COMPLAINT ISN'T SO MUCH THE FACT THAT MY BRAKE LINE RUSTED OUT AS IT IS A 10 YEAR OLD TRUCK, (ALTHOUGH STAINLESS LINES WITH STEEL CONNECTORS WOULD BE A HUGE IMPROVEMENT). BUT MY COMPLAINT IS THAT THE ABS SYSTEMS IN THESE TRUCKS, AND MAYBE OTHER VEHICLES ARE FLAWED. BACK BEFORE ABS CAME OUT, IF A LINE WAS DAMAGED OR FAILED FOR WHATEVER REASON THE SEPARATED RESERVOIRS IN MC'S WOULD AT LEAST GIVE YOU FRONT OR REAR BRAKES TO STOP. THAT WAS THE BEST SINGLE DESIGN IMPROVEMENT MANUFACTURERS MADE TO BRAKES, AND I'VE BEEN DRIVING WHEN MC'S ONLY HAD ONE RESERVOIR. TO HAVE A COMPLETE MC DRAINED FOR A LINE FAILURE IS LUDICROUS. *TR

DRIVING ON THE FREEWAY, I STEPPED ON THE BRAKES TO SLOW DOWN AS TRAFFIC WAS HEAVY IN A AREA THAT IS SLOW IN THE MORNING. THE BRAKES STARTED TO SLOW ME DOWN, THEN WITHOUT WARNING THE PEDAL WENT TO THE FLOOR AND I COULD NOT SLOW THE TRUCK. I TOOK ACTION AND MOVED ONTO THE NEXT LANE TO AVOID A CRASH. I CONTINUED TO APPLY THE BRAKES WHICH ONLY WORKED A LITTLE BIT UNTIL I CAME TO A STOP. I HAD THE TRUCK TOWED TO MY HOUSE. UPON INSPECTION, ONE OF THE FOUR BRAKE LINES THAT RUN ALONG THE OUTSIDE OF THE FRAME UNDER THE DRIVERS SEAT HAD BURST DUE TO EXTENSIVE RUST. IN FACT ALL FOUR OF THE BRAKE LINES IN THIS LOCATION HAD EXTENSIVE RUST. I HAD TO HAVE ALL FOR REPLACED. *TR

UPON APPLYING BRAKES TO SHIFT INTO REVERSE, PEDAL WENT TO FLOOR AND ALL WARNING LIGHTS CAME ON. HAD TRUCK TOWED TO GARAGE, AND UPON INSPECTION A METAL BRAKE LINE HAD RUSTED OUT. AFTER REPLACING BRAKE LINE GARAGE WAS BLEEDING BRAKES AND ANOTHER LINE FAILED. WAS TOLD BY MECHANIC THAT I SHOULD HAVE ALL THE METAL LINES REPLACED BECAUSE OF SEVER RUSTING OF THE METAL. THIS SEEMS TO BE MORE PREVALENT IN GENERAL MOTORS THAN ANY OTHER BRAND. I WAS TOLD THAT THE USE OF SALT BRINE SOLUTION IN OUR AREA FOR WINTER FREEZING IS THE REASON BEHIND THIS. I WAS TOLD THAT THE MECHANIC IS SEEING AT LEAST ONE VEHICLE A WEEK WITH THIS PROBLEM. *JS

MY MOTHER BORROWED MY TRUCK TO RUN AN ERRAND ON HER WAY HOME SHE CALLED TO TELL ME THAT THE "SERVICE BRAKE SYSTEM" MESSAGE HAD APPEARED IN THE DIC. MOMENTS LATER THE VEHICLE LOST ALL STOPPING ABILITY. THANKFULLY DUE TO THE COMBONATION OF AN EMPTY ROAD GOOD DRIVING NO COLLISION OCURED. THIS MORNING I GO TO INVEGISTATE TO FIND COMPLETE RUST THROUGH ON TWO OF THE STEEL HYDRAULIC LINES LOCATED JUST BEHIND THE DRIVERS FRONT WHEEL. ALL STEEL LINES IN THIS TRUCK BRAKE, FUEL, AND, TRANSMISSION COOLER HAVE SIMILAR EXTENSIVE RUST DAMAGE. THIS IS EXTREMELY DANGERIOUS AND WILL BE EXPENSIVE TO REPAIR AS TO ENSURE SAFETY ALL METAL LINES WILL NEED CHANGING. I CAME TO FIND OUT THAT NOT ONLY IS THIS A VERY COMMON ISSUE WITH THESE TRUCKS BUT THAT GM IS DOING NOTHING TO HELP OWNERS NOR DO THEY OFFER CORRECT QUALITY OE STYLE REPLACEMENT LINES. I WAS QOUTED OVER $1000 BY TWO SEPERATE DEALERS IN MY AREA. MY TRUCK IS WELL TAKEN CARE OF AND IS DRIVEN MUCH LESS THAN THE NATIONAL AVERAGE THIS FAILURE HAS TRULY UPSET ME I DONT SEE BUYING ANOTHER GM PRODUCT IN THE FUTURE. *TT
