IllustrationAT ABOUT 10 MPH WHEN BRAKING BRAKE PEDDLE GETS HARD ABS TRIES TO ENGAGE. BUT YOU HAVE NO BRAKES. I HAVE HEARD ITS DUE TO A CORRODED ABS SENSORS. WHY THERE IS NO RECALL WHEN THIS IS A SAFETY ISSUE IS BEYOND ME. THIS IS A DESIGN FLAW AS SEVERAL MECHANICS HAVE SAID ON LINE. *TR

WHEN BRAKING AT LOW SPEEDS THE ABS WOULD COME ON AND THE VEHICLE WOULD NOT STOP ON SOLID DRY PAVEMENT. UPON MY INVESTIGATION WHAT I FOUND WAS THE FRONT HUB BEARING SEAL RUSTED OUT. THIS CAUSED ROAD SALTS/WATER TO ENTER THE HUB ASSY.. THIS THEN CREATED A RUST THAT GATHERED ON THE MAGNETIC ABS SPEED SENSOR . THE GM CAMPAIGN UNDER NHTSA CAMPAIGN NUMBER: 05V379000 SAYS THIS IS DUE TO AN EXTERIOR RUST ISSUE. THIS IS NOT WHAT I FOUND ! WHEN THE GM PROCEDURE TO REPAIR THIS IS DONE , IT WILL FIX THE PROBLEM FOR A SHORT TIME BECAUSE THE RUSTED GREASE IS REMOVED FROM THE SENSOR TIP . I REPLACED BOTH FRONT HUB ASSY AND THIS IS NOW NOT A DEFECT . MY COMPLAINT IS THAT MANY HAVE REPORTED THAT , THIS IS A ONE TIME FIX, SO IT IS MY BELIEF GM SOLD THIS QUICK FIX TO NHTSA TO CHEAP OUT ON THE REAL FIX , WHICH IS TO REPLACE THE FRONT HUB ASSY AND USE SEALS WITH A RUST RESISTANT METAL . IT IS A LOT CHEAPER TO REMOVE THE RUST OFF THE SENSOR TIP , THAN TO FIX THE REAL CAUSE WHICH IS A RUSTED DAMAGED HUB ASSY DUE TO POOR METAL QUALITY OF THE GREASE/HUB BEARING SEAL. I HAVE BEEN WORKING ON TRANSPORTATION VEHICLES SINCE 1977 INCLUDING VEHICLES WITH ABS BRAKING SYSTEMS . *TR

I WENT TO MOVE MY TRUCK FROM MY DRIVEWAY TO THE STREET. AS I WAS LEAVING THE DRIVEWAY I HAD TO PUSH AS HARD AS I COULD TO GET THE TRUCK TO STOP. I WAS ABLE TO STOP THE TRUCK ONLY WHEN THE BRAKE PEDAL WAS AS FAR AS I COULD PUSH IT DOWN. I DROVE IT AROUND THE BLOCK TO SEE IF THE BRAKES WOULD WORK BETTER. I STILL HAD TO PUSH DOWN ALL THE WAY AND IT LOOK A LONG TIME TO STOP. I WAS NOT CONFORMABLE DRIVING MUCH OVER 10 MPH. WHEN I GOT BACK TO THE DRIVEWAY I NOTICED A LINE OF FLUID. I LOOKED AT THE REAR DRIVE SIDE WHEEL WELL AND THERE WAS BRAKE FLUID ALL OVER IT. IT APPEARS THE BRAKE LINE TO RUSTED THROUGH. *TR

WHILE DRIVING ONE DAY, I NOTICED THE TOW/HAUL BUTTON DIDN'T WORK, THEN THE GAS GAUGE. EVENTUALLY, WITHIN A YEAR, ALL THE GAUGES STOPPED WORKING. SOMETIMES THEY GO ON AND LATER OFF AGAIN. I DON'T KNOW IF THEY ARE EVEN ACCURATE TO ANY DEGREE WHEN THEY DO COME ON. ABOUT A YEAR AGO THE TRUCK SHUT OFF WHILE I WAS DRIVING BUT AFTER I WAS SAFELY OFF THE ROAD IT STARTED AGAIN. THAT HAS NOT HAPPENED SINCE. I HAVE TRIED TO FIND THE PROBLEM BUT AS OF NOW I HAVE BEEN UNSUCCESSFUL. MYSELF OR MY MECHANIC, WHO WORKS FOR THE COUNTY AND IS VERY CAPABLE. I KNOW MANY PEOPLE WITH THE SAME OR SIMILAR VEHICLES AND THIS SEEMS TO BE QUITE COMMON. I ALSO OWN A 2003 SUBURBAN AND THESE THINGS ARE STARTING WITH THAT TRUCK TOO. THESE HAVE BEEN GOOD TRUCKS BUT I WANT TO BE SAFE AND NOT HAVE TO GET RID OF MY VEHICLES. ABS,WIPERS,DEFROST,HVAC, AND ALL GAUGES ARE AFFECTED. I HAVE REPLACED HVAC CONTROLS AND DASH GAUGES AND OTHER PARTS BUT STILL THE SAME PROBLEMS. SUCH AS WHATEVER HVAC CONTROLS THAT I PUT IN IT STILL ONLY WORKS ON HIGH. WATCH OUT IF YOUR SPEEDOMETER ACTS STRANGE. *TR

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.
