PARKED MY 1999 CHEVROLET K PICKUP AT A STORE AND JUST BEFORE I TURNED THE ENGINE OFF, THE ABS LIGHT CAME ON. WHEN THE IGNITION WAS OFF, THERE WAS A GRINDING NOISE FROM UNDER THE VEHICLE. APPARENTLY THE ABS MODULE WAS STILL RUNNING. I CRAWLED UNDER THE VEHICLE AND UNPLUGGED IT. WHEN I TOOK IT TO MY GM MECHANIC, HE TOLD ME THAT THE EBCM SHORTED OUT AND APPARENTLY HAPPENS FREQUENTLY TO THIS MODEL. IT COST ME $781 FOR THE PART PLUS LABOR OF $202.50. I WAS UNIMPRESSED, ESPECIALLY TO FIND OUT THAT THERE HAS BEEN SO MUCH PROBLEM WITH THIS AND THAT THERE IS NO RECALL FOR IT. CAN YOU HELP? ISN'T THIS A SAFETY ISSUE? MY VEHICLE ONLY HAS 50496 MILES ON IT.*AK

ABS PUMP WENT OUT, LUCKLY I HAD AN EXTENDED WARRANTY AND ONLY HAD TO PAY $100.00 INSTEAD OF $800.00. ALSO MANY OTHER TRUCKS IN THE AREA WITH SAME PROBLEM. HAD KLUNKING NOISE IN REAR END CARRIED TO TWO DIFFERENT DEALER SHIPS AND COULD NOT FIND ANYTHING. SOUNDED LIKE TRANSMISSION WAS PLAYING CATCH UP WITH REAREND. THREE MONTHS AFTER WARRANTY GOES OUT IT DOES THE SAME THING AND BUST THE GEARS IN TRANSMISSION. MOTOR SOUNDS LIKE IT IS KNOCKING WHEN YOU FIRST CRANK IT UP. THE DEALERSHIPS AROUND ARE QUICK TO SELL YOU A CAR BUT WILL NOT STAND BEHIND YOU WHEN THERE ARE PROBLEMS. THIS WILL PROBALLY BE MY LAST CHEVY!!! *JB

THE ABS MODUAL ON MY 1999 K1500 CHEVYROLET TRUCK HAS GONE BAD. THE PUMP STAYS ON AT ALL TIMES, UNLESS YOU PULL OUT THE FUSE FOR THE ABS. BY DISCONNECTING THE FUSE, THE ABS BRAKES ARE DISABLED FOR THE TRUCK. THIS ALSO LEAVES THE ABS LIGHT AND BRAKE LIGHT IN THE DASH ON. THE REPLACEMENT FOR THIS PART IS AROUND $1000. THIS APPEARS…

THE ABS MODUAL ON MY 1999 K1500 CHEVYROLET TRUCK HAS GONE BAD. THE PUMP STAYS ON AT ALL TIMES, UNLESS YOU PULL OUT THE FUSE FOR THE ABS. BY DISCONNECTING THE FUSE, THE ABS BRAKES ARE DISABLED FOR THE TRUCK. THIS ALSO LEAVES THE ABS LIGHT AND BRAKE LIGHT IN THE DASH ON. THE REPLACEMENT FOR THIS PART IS AROUND $1000. THIS APPEARS TO BE A FAIRLY COMMON PROBLEM ON THIS MODEL TRUCK.MY FATHER IS HAVEING THE SAME LUCK WITH HIS 1999 K2500. NOTE THAT THE DEALER RECOMMENDED FIX, SHORT OF REPLACING THE UNIT, IS PULLING OUT THE FUSE. *AK

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.
