WE OWN A 2001 GMC SIERRA 1500 PICKUP TRUCK WITH AROUND 55K MILES. LAST DEC 2010 THE BRAKES FAILED WHEN APPLYING PRESSURE. WE THOUGHT THE PROBLEM WAS ONE OF THE REAR CALIPERS; HOWEVER, UPON FURTHER DIAGNOSIS, IT WAS DETERMINED THE BRAKES LINES HAD RUSTED AND SUBSEQUENTLY BURST/RUPTURED DURING A BRAKE APPLICATION. FORTUNATELY, THE VEHICLE WAS CLOSE TO HOME WHEN THE BRAKES FAILED AND WE MANAGED TO GET OUR TRUCK HOME WITHOUT INCIDENT. WE LEFT OUR TRUCK PARKED OVER THE WINTER TO DEAL WITH THE ISSUE WHEN THE WEATHER WOULD BE MORE COOPERATIVE FOR HAVING OUR VEHICLE TOWED TO A REPAIR SHOP. I CONTACTED GM EARLY MARCH 2011 REGARDING OUR PROBLEM AND GM SAID A GM AUTHORIZED DEALER HAD TO DIAGNOSIS THE PROBLEM. WE HAD OUR PICKUP TOWED TO A LOCAL GMC DEALER AND THE DEALER?S SERVICE DEPT CHARGED US $98 TO INSPECT OUR VEHICLE. THE DEALER REPORTED BACK TO GM THAT THE CORROSION WAS CAUSED BY LACK OF MAINTENANCE. THE DEALERS ESTIMATE WAS $4,657 TO REPLACE THE BRAKE LINES AND PERFORM OTHER MAINTENANCE WORK CAUSED BY THE LINES RUPTURING. IF THE "EBCM FOR THE ANTI-LOCK BRAKES DID NOT HAVE TO BE REPLACED, THEN THE DEALER?S ESTIMATED REPAIR BILL WAS REDUCED TO $3,316. I INFORMED GM THAT I'VE OWNED 10 OR SO VEHICLES IN MY LIFETIME AND NEVER HAD ANY BRAKE LINES CORRODE/RUPTURE DURING A BRAKE APPLICATION NOR DID I HAVE TO HAVE PREVENTATIVE MAINTENANCE PERFORMED ON THE BRAKE LINES TO PREVENT THEM FROM CORRODING. OTHER OWNERS OF GM PICKUPS/SUVS HAVE ALSO FILED COMPLAINTS ON NHTSA?S WEBSITE FOR THIS SAME BRAKE LINE FAILURE PROBLEM DUE TO CORROSION. A PRELIMINARY EVALUATION WAS OPENED BY NHTSA TO DETERMINE THE FREQUENCY, SCOPE AND SAFETY CONSEQUENCES OF THE ALLEGED DEFECT IN GM PICKUPS/SUVS MANUFACTURED DURING 1999 TO 2003. THE INVESTIGATION NUMBER IS "PE 10-010" DATED 30 MARCH 2010. THE SUBJECT IS "BRAKE LINE FAILURE DUE TO CORROSION". THIS INVESTIGATION WAS OPENED MARCH 2010 AND I CANNOT LOCATE ANY UPDATES ON THE NHTSA WEBSITE. UPDATED 05/19/11 *TR

PROBLEM IS INTERMITTENT. BRAKE AND ABS WARNING LIGHTS COME ON AND STAY ON UNTIL ENGINE IS TURNED OFF. NO DETECTABLE CHANGE IN BRAKING. SEPARATELY, BUT ALSO INTERMITTENTLY, AT LOW SPEEDS (NO WARNING LIGHTS) THE ABS IS ENGAGED WHILE BRAKING, MAKING THE VEHICLE HARD TO STOP AT TIMES. THIS SEEMS TO OCCUR MOST FREQUENTLY WHEN TURNING TO THE LEFT. SYMPTOMS ARE VERY SIMILAR, IF NOT IDENTICAL TO NHTSA CAMPAIGN ID NUMBER : 05V379000. MANY ANECDOTAL DESCRIPTIONS OF THIS SAME PROBLEM IN 1999-2002 GMC LIGHT TRUCKS CAN BE EASILY FOUND ON THE INTERNET.
THIS PROBLEM CONCERNS MY 2001 GMC SIERRA AND GM'S RECALL NUMBER 05068. THE RECALL CONCERNS THE ABS AND A RUST PROBLEM.

THIS PROBLEM CONCERNS MY 2001 GMC SIERRA AND GM'S RECALL NUMBER 05068. THE RECALL CONCERNS THE ABS AND A RUST PROBLEM. I HAD THE RECALL PERFORMED ON OCT. 19, 2005 AND THERE WAS 47,249 MILES ON THE ODOMETER. I NOTICED A BRAKING PROBLEM LAST WEEK WITH MY TRUCK. AFTER DOING A SEARCH ON THE INTERNET, I DECIDED IT WAS PROBABLY A ABS SENSOR PROBLEM. I TOOK IT TO THE SAME DEALER THAT DID THE ORIGINAL RECALL. THEY CHECKED WITH GM REGIONAL MANAGER AND SAID IT WAS ALREADY COVERED ONCE AND WOULDN'T COVER IT A SECOND TIME. I HAD THE REPAIR DONE AT THE DEALERSHIP ON DEC. 8, 2010 AND THE MILEAGE WAS 65,849. SO THE EFFECT OF THE RECALL ONLY LASTED 18,600 MILES. I KNOW 5 YEARS HAVE PAST, BUT THE SAME ISSUE IN THAT FEW MILES? I SENT AN EMAIL TO GM ON DEC. 9 AND THEY PHONED ME THIS MORNING. SAID THE VEHICLE AGE WAS SUCH THAT THEY WOULDN'T DO ANYTHING. IF I HAD 150,000 MILES OR SO ON THE TRUCK, I WOULDN'T THINK THAT MUCH ABOUT THIS. HOWEVER, THIS IS A PROBLEM THAT GM ISSUED A RECALL ON AND FROM WHAT A UNDERSTAND, THE ORIGINAL RECALL DID NOTHING BUT REMOVE RUST FROM THE SENSOR AND TREAT THE SURFACE. I WOULD THINK A RECALL WOULD LAST MORE THAT 18,600 MILES. I DON'T KNOW IF YOU HAVE HAD ANY OTHER PEOPLE WITH THE SAME CONCERN ABOUT THE RECALL ONLY STALLING A PROBLEM LATER ON DOWN THE ROAD, BUT WANTED TO MAKE YOU AWARE OF THE CONCERN I HAVE. THE BRAKES WILL FAIL AT LOW SPEEDS WHEN THEY ARE APPLIED AND THE MESSAGE CENTER IN THE DASH DOES NOT GIVE ANY MESSAGE. THANK YOU. *TR

BRAKING SYSTEM BEGAN FAILING AT LOW SPEEDS (< 10 MPH), ALMOST CAUSING ME TO REAR END VEHICLES WHEN TRYING TO STOP. TOOK THE VEHICLE TO A DEALER, WHO CLEANED THE WHEEL SPEED SENSORS AT A COST OF $110. ONE MONTH LATER, THE BRAKES BEGAN FAILING AGAIN AND AFTER RESEARCHING ON-LINE, FOUND A GM RECALL FOR 1999-2002 GMC SIERRAS. CONTACTED GM BUT WAS INFORMED ONLY VEHICLES WITH CERTAIN VIN #'S ARE INCLUDED, AND MINE IS NOT ONE OF THEM. I HAVE CHILDREN AND FREQUENTLY DRIVE IN SCHOOL ZONES AROUND SCHOOL BUSES AND CHILDREN AT LOW SPEEDS (<15 MPH). THIS IS A VERY DANGEROUS SITUATION BECAUSE THE VEHICLE WILL NOT STOP.
DRIVING AT APPROXIMATELY 35 MPH, APPLIED BRAKES WHEN APPROACHING A RED LIGHT. BRAKE PEDAL WENT DOWN TO THE FLOOR, TRUCK WENT INTO THE INTERSECTION AND FINALLY CAME TO A STOP. THERE WERE NO INDICATION OF PROBLEM BEFORE THIS OCCURRED. TRUCK TAKEN TO A REPAIR SHOP. ALL BRAKE LINES WERE RUSTED AND WERE REPLACED. I REQUESTED THAT…

ON CERTAIN VANS EQUIPPED WITH SURE-LOK WHEELCHAIR SECUREMENT SYSTEMS, THE SPROCKET TEETH OF THE RETRACTOR ASSEMBLY IS OUT OF ALIGNMENT.
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE WHEELCHAIR MAY NOT BE ADEQUATELY SECURED POSSIBLY RESULTING IN INJURIES TO A WHEELCHAIR OCCUPANT.
Remedy: DEALERS WILL INSPECT AND REPLACE THE WHEELCHAIR SECUREMENT RETRACTORS AS NECESSARY. SURE-LOK WILL HANDLE THE REPAIRS FOR THIS CAMPAIGN. OWNERS SHOULD CONTACT SURE-LOCK AT 1-908-231-1804 OR MOBILITYWORKS AT 1-800-769-8267.

Apr 10, 2001
VEHICLE DESCRIPTION: CERTAIN 2-WHEEL DRIVE PICKUP TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE PROBLEM WAS CAUSED BY A COMPUTER ERROR THAT RESULTED IN THE CERTIFICATION LABEL LISTING TIRE SIZE AND INFLATION PRESSURE INFORMATION THAT DIFFER FROM THE TIRE SIZE AND THE INFLATION PRESSURE INFORMATION FOR THE TIRES ON THE VEHICLE. IF THE VEHICLE OWNER OR SOMEONE SERVICING THE VEHICLE INFLATES THE TIRES ACCORDING TO THE PRESSURE SPECIFIED ON THE LABEL VERSUS THE APPROPRIATE PRESSURE FOR THE TIRES, THE TIRES COULD BE UNDER-INFLATED OR OVER-INFLATED DEPENDING ON THE TIRES MOUNTED ON THE VEHICLE.
Consequence & remedy
Consequence: IF THE TIRES ARE UNDER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE, AND THE TIRE COULD DEGRADE TO A POINT OF ALLOWING SUDDEN AIR LOSS. IF THE TIRES ARE OVER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE AND INCREASE SUSCEPTIBILITY TO ROAD HAZARD DAMAGE. IF SUDDEN AIR LOSS OR A ROAD HAZARD CAUSES DAMAGE TO A TIRE, CONTROL OF THE VEHICLE COULD BE ADVERSELY AFFECTED AND COULD RESULT IN A VEHICLE CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH A NEW LABEL AND INSTALLATION INSTRUCTIONS. HOWEVER, A DEALER CAN INSTALL THE LABEL IF THE OWNER SO DESIRES. OWNER NOTIFICATION BEGAN MAY 31, 2001. OWNERS WHO DO NOT RECEIVE THE LABEL AND INSTALLATION INSTRUCTIONS WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

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.
