THE CONTACT STATED THAT THE DEALER ONLY CLEANED THE ABS SENSOR FOR CORROSION. YEARS LATER, THE BRAKE PEDAL FAILED TO RESPOND DUE TO INTERNAL CORROSION REGARDING THE SENSOR. ALSO, THE ABS KEPT INTERMITTENTLY ACTIVATING AND CAUSED EXTREME DIFFICULTY WHEN BRAKING. THE BRAKE PEDAL FAILED TO STOP THE VEHICLE AND CAUSED THE DRIVER TO HAVE TO REVERSE MORE THAN TWICE TO PREVENT A CRASH. THE DEALER WAS NOTIFIED OF THE FAILURES AND INDICATED THAT THE ABS SENSOR MAY NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS NOT AVAILABLE.

WENT TO STOP AND THE BRAKE PEDAL PUSHED AGAINST MY FOOT INSTEAD OF GOING DOWN. WAS MOVING SLOWLY AND THE BRAKE PEDAL INSTEAD OF STOPPING THE CAR PUSHED MY FOOT UP FROM THE BRAKE PEDAL AND I WENT OVER A PARKING BRAKE. MECHANIC VERIFIED THAT WHEN WHEEL SENSOR GOES BAD THE VEHICLE THINKS THE BRAKES ARE LOCKING UP AND THE ABS SYSTEM GOES ON PUMPING BRAKE PEDAL. HAPPENED MULTIPLE TIMES AS APPROACHED STOP LIGHTS PUSHING ME INTO INTERSECTION INSTEAD OF STOPPING.. I BELIEVE WHEN THE WHEEL SENSOR IS BAD IT SHOULD NOT PUT ME OR OTHERS IN A DANGEROUS SITUATION.

DURING A NORMAL STOP AT A STOP SIGN ON A RURAL ROAD, A STEEL BRAKE LINE RUPTURED DUE TO EXCESS CORROSION. THIS ONE LINE BETWEEN THE MASTER CYLINDER AND ABS MODULE IS THE ONLY LINE THAT PROVIDES PRESSURE TO THE FRONT BRAKES, WHICH SUPPLY ROUGHLY 75% OF THE VEHICLE'S BRAKING POWER. THE RUPTURE RESULTED IN RAPID FLUID LOSS AND THEREFORE A LACK OF PRESSURE IN THE HYDRAULIC SYSTEM TO ALLOW FOR ADEQUATE BRAKING. NEEDED TO SWERVE INTO A DITCH TO AVOID A CRASH WITH CROSS TRAFFIC.VISUAL INSPECTION INDICATES MOST BRAKE LINES ARE EXTREMELY CORRODED, AND WERE OBVIOUSLY MADE WITH SUBSTANDARD MATERIALS AS COMPARED TO OTHER MANUFACTURERS. I DO RECOGNIZE THAT THIS IS AN OLD VEHICLE, HOWEVER OTHER VEHICLES OF SIMILAR AGE AND DRIVEN IN SIMILAR ENVIRONMENTS DO NOT HAVE THIS ISSUE. ONLINE RESEARCH, MOST NOTABLY THE COMPLAINTS FILED TO NHTSA, INDICATE THIS IS A COMMON PROBLEM WITH CHEVY/GMC TRUCKS OF THIS ERA. ALTHOUGH OTHER OEM'S (SUBARU) HAVE ISSUED RECALLS IN SIMILAR SITUATIONS, IT APPEARS THAT THE GM THAT THE PUBLIC BAILED OUT JUST A FEW YEARS AGO HAS DECIDED TO DENY THAT THIS IS A PROBLEM, GAMBLING THAT THE THE COST OF LAWSUITS ASSOCIATED WITH DEATHS DO NOT EXCEED THE COST OF A RECALL.

BRAKE FAILURE FOR THE SECOND TIME ON THE VEHICLE. ORIGINAL BRAKE LINES WERE REPLACED 7 OR 8 YEARS AGO DUE TO FAILURE AT MY OWN COST (RUSTED LINES, LEADING THEM TO FAIL AS THE BRAKES WERE APPLIED), ALL LINES WERE REPLACE WITH GM REPLACEMENT LINES BY A QUALIFIED TECHNICIAN. ORIGINAL FAILURE RENDERED THE BRAKES 0% OPERATIONAL, GRAVITY (UPHILL) WAS THE ONLY THING THAT STOPPED THE VEHICLE. THE MOST RECENT FAILURE (ON JULY 29, 2017) AFFECTED THE BRAKE LINE RUNNING TO THE FRONT-RIGHT CALIPER, LINE FAILED WHERE IT CROSSED OVER THE SKID PLATE NEAR THE CENTER-LINE OF THE VEHICLE UP FRONT BY THE LOWER RADIATOR SUPPORT. LINE FAILED DUE TO CORROSION. REAR BRAKES APPEAR TO BE WORKING BUT ARE NOT SUFFICIENT TO STOP THE VEHICLE IN A SAFE MANNER. NO ACCIDENT OCCURRED, LINE FAILED AS APPROACHING A LIGHT TURNING RED WHILE GOING UPHILL, ROLLED THROUGH THE INTERSECTION PRIOR TO THE LIGHT TURNING GREEN FOR CROSSING TRAFFIC AND WAS ABLE TO STOP THE VEHICLE AS IT DRIFTED TO A STOP UPHILL. THE QUALITY OF THE GM BRAKE LINES ARE VERY SUSPECT TO SAY THE LEAST. THE BRAKE LINES ARE DANGEROUS AND SEEM TO BE MORE SUSCEPTIBLE TO CORROSION THAN ANY OTHER BRAKE LINE ON ANY OTHER VEHICLE I'VE EVER OWNED, OR ANY OF MY FRIENDS OR FAMILY HAVE EVER OWNED. I CAN ONLY IMAGINE IF THE LINES FAILED UNDER DIFFERENT CIRCUMSTANCES (WHILE TOWING THOUGH MOUNTAINS WHILE GOING DOWNHILL FOR EXAMPLE, THIS WOULD BE A LIFE-THREATENING SITUATION). PLEASE DETERMINE IF THESE LINES ARE FAULTY FOR THE SAKE OF OTHERS WITH THESE VEHICLES, AND THE SAKE OF OTHER MOTORISTS THAT COULD BE IMPACTED WHEN THE BRAKES ON THIS LARGER VEHICLE FAIL. IF THEY ARE FOUND TO BE FAULTY OWNERS SHOULD BE NOTIFIED THAT THESE BRAKE LINES ARE SUBPAR, AND THAT THE MANUFACTURER'S REPLACEMENT LINES ARE ALSO SUBPAR.
BRAKE LINE RUNNING ON TOP OF FRAME FROM MASTER CYL TO ABS HAS CORRODED TO THE POINT OF FAILURE. IT HAS RUSTED THROUGH AND LEAKS BRAKE FLUID. BRAKES HAVE FAILED. THIS VEHICLE HAS NEVER LEFT FLORIDA AND IS STILL HELD BY ORIGINAL OWNER.

WHILE DRIVING MY VEHICLE AND TOWING A 4000+ POUND BOAT, MY BRAKE PETAL WENT TO THE FLOOR. WHEN I GOT OUT OF THE VEHICLE, THERE WAS BRAKE FLUID LEAKING ON THE GROUND. I DETACHED THE BOAT AND ATTEMPTED TO SEE IF I COULD DRIVE THE VEHICLE TO THE REPAIR FACILITY. THERE WAS NO BRAKING POWER AVAILABLE SO THE VEHICLE WAS TOWED TO A REPAIR FACILITY. REPAIRS WERE AROUND $900 FOR A REPLACEMENT OF ALL THE RUSTED BRAKE LINES.

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.
