MY BRAKE LINES ON MY SILVERADO HAVE BEEN REPLACED 5 DIFFERENT LINES IN 4 YEARS THE TRUCK HAS 90,000 MILES ON IT AND IN THE LAST MONTH 3 TIMES IVE LOST BRAKES THE GUY WHO FIXES MY BRAKE LINES TELLS ME THE LINES ARE RUSTED OUT EACH TIME THIS HAPPENS, HE TOLD ME HE CANT TELL BY SIGHT WHEN THEY WILL FAIL CAUSE THEY LOOK OK BUT THAT'S NOT THE CASE, I'VE READ THIS IS A ISSUE WITH THESE VEHICLE'S IVE BEEN LUCKY SO FAR (KNOCK ON WOOD) BUT THE COST AND THE STRESS OF HAVING YOUR BRAKES FAIL IS UNACCEPTABLE SEEING THE LINES ARE NOT UP TO NORMAL STANDARDS, SOMEONE SHOULD BE HELD RESPONSIBLE FOR THIS ISSUE
SEATBELTS DOES NOT CATCH AND WILL NOT RECOIL. STARTED OUT AS LOOSE NOW IT WILL NOT RETRACT. STARTED WHEN I APPLIED THE BRAKES WHEN A DOG RAN IN FRONT OF ME AND SEATBELTS DID NOT CATCH AND MY CHEST HIT THE STEERING WHEEL. THE SEATBELTS DID NOT RETRACT AFTER IT PULL OUT. I WAS TRAVELING 55 MPH WHEN THE DOG CROSSED THE HIGHWAY.
IN JULY OF 2018, MY 2002 CHEVROLET SILVERADO HAD MAJOR BRAKE FAILURE AS I WAS DRIVING ABOUT 35 MPH APPROACHING A RED LIGHT. I PRESSED ON THE BRAKES, IT WENT TOTALLY TO THE FLOOR AND I WAS UNABLE TO STOP, BLOWING RIGHT THROUGH RED LIGHT.

IN JULY OF 2018, MY 2002 CHEVROLET SILVERADO HAD MAJOR BRAKE FAILURE AS I WAS DRIVING ABOUT 35 MPH APPROACHING A RED LIGHT. I PRESSED ON THE BRAKES, IT WENT TOTALLY TO THE FLOOR AND I WAS UNABLE TO STOP, BLOWING RIGHT THROUGH RED LIGHT. MY MECHANIC TOLD ME THE MY BRAKE LINE RUSTED THROUGH, AND ALL THE BRAKES LINES, AS WELL AS THE FUEL LINE IS TOTALLY RUSTED. I WAS TOLD THAT THIS IS VERY COMMON IN THIS CHEVROLET / GM MODEL ERA. HE SAID IF ALL HE WERE TO DO IS REPLACE BRAKE LINES IN THIS 1999 TO 2006 ERA, IT WAS ENOUGH TO KEEP HIS BUSINESS BOOMING. WHAT SHOCKING STRUCK ME IS THAT HE TOLD ME THEY ALL FAIL UNDER THE DRIVERS SIDE DOOR, ALONG THE FRAME, BEFORE THE ABS MODULE. THIS IS DEFINITELY A SAFETY HAZARD THAT SHOULD BE ADDRESSED. MYSELF, AS WELL AS OTHERS COULD OF BEEN KILLED WHEN I WAS UNABLE TO STOP AT THE RED LIGHT. JOHN D. NORRISTOWN, PA.
THERE IS A MAJOR SAFETY DESIGN FLAW IN THE 1999-2002 BRAKE SYSTEM. THE FRONT TIRES THROUGH THE SALT AND GRIME FROM THE ROADS ONTO THE BRAKE LINES WHERE CHEVROLET HAS LOCATED THEM IN THE DESIGN. THIS CAUSES THE BRAKE LINES TO CORRODE AND BURST DURING DRIVING. MINE HAVE NOW BURST FOR THE SECOND TIME IN THE LAST 5 YEARS. THE FIRST…

THERE IS A MAJOR SAFETY DESIGN FLAW IN THE 1999-2002 BRAKE SYSTEM. THE FRONT TIRES THROUGH THE SALT AND GRIME FROM THE ROADS ONTO THE BRAKE LINES WHERE CHEVROLET HAS LOCATED THEM IN THE DESIGN. THIS CAUSES THE BRAKE LINES TO CORRODE AND BURST DURING DRIVING. MINE HAVE NOW BURST FOR THE SECOND TIME IN THE LAST 5 YEARS. THE FIRST TIME IN 2013 I WAS DRIVING AT ABOUT 35-40 MPH WHEN I WENT TO MAKE A RH TURN AND THE BRAKES WENT TO THE FLOOR. THIS TIME I HAD WENT TO A LOCAL GAS STATION AND WAS ON THE WAY HOME WHEN I STOPPED TO TALK TO A NEIGHBOR AND ONCE AGAIN THE BRAKE PEDAL WENT TO THE FLOOR. I DRIVE THE TRUCK VERY LITTLE SO I HAVE ONLY PUT JUST OVER 17,000 MILES ON THE NEW SET OF BRAKE LINES THAT I HAD INSTALLED BY A CHEVROLET DEALER IN 2013. I LIVE IN SOUTHERN INDIANA, JUST NORTH OF LOUISVILLE, KY SO OUR WINTERS ARE NOT THAT HARSH, SO THE AMOUNT OF SALT FROM ROADS IS PRETTY LIMITED. I HAVE TALKED WITH OTHER CHEVROLET SILVERADO, YUKON AND SUBURBAN OWNERS AND THEY ALL SHARE HAVING THE SAME ISSUES WITH THEIR BRAKE LINES. I HAVE WENT TO YOUTUBE TO SEE HOW TO MAKE THE REPAIRS MYSELF AND HAVE SEEN COUNTLESS VIDEOS ON INDIVIDUALS REPAIRING THEIR BRAKES BECAUSE OF THE CORROSION AND THE BRAKE LINES BURSTING. COME ON NHTSB WHAT ARE YOU WAITING ON BEFORE YOU ISSUE A RECALL, SOMEONE TO DIE OR BE PERMANENTLY DISABLED! DO THE RIGHT THING AND ISSUE A RECALL TO FIX THE BRAKES WITH STAINLESS STEEL LINES, ROTORS, CALIPERS AND BRAKE PADS THAT WILL NOT RUST AFTER A FEW YEARS!
I FIRST OF ALL ABOUT A YEAR AGO AND NOTICED 2ND GEAR HAS GONE OUT IN IT SINCE I VERY RARELY WENT IN THE REVERSE IT DIDN'T NOTICE THAT TELL HER I WAS IN A PREDICAMENT AND HAD TO PUSH IT OUT AND NOW IT'S STUCK IN FIRST GEAR
I WAS DRIVING AT LOW SPEED ON A STREET THAT IS 25MH AS I BREAK TO STOP AT THE STOP SIGN MY ABS ACTIVATED. ALMOST CAUSED ME A SERIOUS ACCIDENT BECAUSE I COULDN'T STOP SO I HAD TO BREAK SO HARD MY BUT WAS ACTUALLY OFF OF THE SEAT. AND THIS CONTINUES TO HAPPEN SO NOW I HAVE TO TAKE THE ABS FUSE OUT TO DEACTIVATE MY ABS.

TAKATA RECALL - HAVE BEEN STRANDED NUMEROUS TIMES AS IT HAS APPEARED TO BE THE FUEL PUMP NOT GETTING GAS TO START THE CAR. SOMETIME CAN HEAR PUMP RUNNING AS I HAVE REPLACE 3-4 PUMPS SINCE 2012 OR 13. SOME TIME BEATING UNDER TANK HELPS. THERE SEEM TO BE NUMEROUS COMPLAINTS ABOUT THIS PROBLEM. SECURITY LIGHT FLASHING AND START SOMETIME WHEN IT IS RESET. SOUNDS WONDERFUL WHEN IT RUNS. CAN IT BE THE COMPUTER? TOWED TO A SAFE LOCATION AFTER NOT STARTING AND DIAGNOSTIC TECHNICIAN SHOW 10% FUEL PRESSURE. I PARKED WENT IN TO MAKE A PAYMENT AT A BUSINESS AND WOULD NOT START FOR 4 DAYS
VEHICLE WAS TRAVELING DOWN A STATE HIGHWAY WHEN IT WENT OFF THE ROAD, DOWN A SHORT EMBANKMENT, HIT AT LEAST 2 TREES BEFORE COMING TO REST. THE COLLISION WAS A FRONTAL COLLISION AND THE VEHICLE WAS A TOTAL LOSS. THE AIRBAG, HOWEVER, DID NOT DEPLOY DURING THE ACCIEENT.

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
