I HAVE A 1998 GMC SIERRA PICK-UP TRUCK. I HAVE EXPERIENCED ONGOING ANTI LOCK BRAKE SENSOR ISSUES SINCE LAST SPRING. THEY ENGAGE AT LOW SPEED AND MAKE IT HARD TO STOP IF YOU ARE NOT PREPARED FOR THE FAILURE AT LOW SPEED. THE DEALER I TOOK THE VEHICLE TO (CAPITOL CADILLAC-LANSING MICH.) SAID THEY "COULDN'T RECREATE THE PROBLEM". THIS WAS A RIDICULOUS STATEMENT BECAUSE IT "RECREATED" ITSELF TWICE AS I WAS LEAVING THE DEALERSHIP PARKING LOT. THEY WERE JUST NOT INTERESTED IN DEALING WITH IT. THERE IS AN ACTIVE RECALL FOR THIS PROBLEM. WHY DOES IT NOT INCLUDE MY TRUCK?? I DON'T SEE WHY I SHOULD HAVE TO SPEND HUNDREDS OF DOLLARS TO HAVE THIS FIXED IF GM IS TAKING CARE OF OTHER OWNERS WITH THE SAME PROBLEM. I AM VERY DISAPPOINTED. *NM

BOTH FRONT BRAKE ABS SENSORS ON MY 1998 GMC SIERRA 4 WHEEL DRIVE HALF TON PICKUP TRUCK FAILED DURING A 90 DAY PERIOD IN 2005. THIS CAUSED THE ABS TO ACTIVATE AT LOW SPEED STOPS NEARLY RESULTING IN ACCIDENTS AND REQUIRING THE REPLACEMENT OF BOTH FRONT WHEEL BEARING/ABS SENSOR ASSEMBLIES AT THE COST OF ABOUT $800. THIS VEHICLE WAS PURCHASED NEW IN AUGUST 1998 AND HAS ABOUT 65,000 MILES OF USE. THE LOCAL GM REP AND GMC'S CUSTOMER RELATIONS TELLS ME THAT THERE IS NOTHING GM WILL DO ABOUT IT. THE LOCAL DEALER TELLS ME IT IS A COMMON PROBLEM AND HAS BEEN FOR MANY YEARS!. *JB

BRAKE DESIGN IS INADEQUATE FOR SIZE OF VEHICLE, ONE TON 4WD TRUCK ALSO MOST 3/4 SUBURBANS AND TRUCKS HAVE THE SAME PROBLEM. IN THE PAST THE TRUCK HAS PULL HARD LEFT ACROSS THE ROAD WITH NO PRIOR WARNING, BRAKE PADS ARE REQUIRED TO BE REPLACED DEPENDING ON PADS EVERY 5000-10000 MILES. THIS TRUCK HAS BEEN IN UNDER WARRANTY THREE TIMES TO REPLACE PADS, ONCE TO REPLACE ROTORS, ONCE TO REBUILD CALIPERS, AND ONCE TO REPLACE REAR DRUMS WITH 21000 MILES ON THE VEHICLE. IT APPEARS THAT NORMAL PASSENGER DESIGN SIZE BRAKES WERE USED ON A LIGHT TRUCK AND THAT THE PROPORTIONING BETWEEN FRONT AND REAR UTILIZE THE REAR BRAKES VERY LITTLE. THIS BRAKE LIFE IS WITH OUT ANY TOWING OR HEAVY HAULING. GIVEN THE LIFE WHICH IS ABNORMALLY LOW, DURING STEEP MOUNTIAN DRIVING ON A LONG TRIP THE FRONT PADS COULD FAIL WITHOUT WARNING AND THE FRONT APPEARS TO BE DOING ALL THE BRAKING ON UNDER DESIGNED SIZE PADS. WHY ELSE WILL THE 2000 MODELS CREW CAB 4WD HAVE HUGH 4 WHEEL DISC BRAKE SETUPS?? GM HAS DONE NOTHING TO RETROFIT OR RESOLVE ISSUES EXCEPT REPLACE PARTS OVER AND OVER, REFERENCE GM FILE # 99063603...THANKS IN ADVANCE FOR ANY ASSISTANCE YOU CAN PROVIDE. *AK

I WAS DRIVING ON A DIRT ROAD ( LUCKILY) THE GROUND WAS WET AND IT HAD BEEN RAINING, ANOTHER VEHICLE APPEARED AND I APPLIED THE BRAKES. THERE WERE NO BRAKES. I KEPT TRYING BUT NOTHING HAPPENED UNTIL A FEW MOMENTS LATER. TO AVOID THE OTHER PERSON I TURNED THE TRUCK AND THE REAR END HIT A TREE. I PAID FOR THE REPAIRS MYSELF. THERE WAS A RECALL ON THE BRAKING SYSTEMS OF MY TRUCK IN THAT TIME PERIOD, BUT GMC SAID MY TRUCK WAS NOT INCLUDED. ( THE SAME EXACT PROBLEM WAS OCCURRING IN THE RECALLED VEHICLES.) THIS IS NOT THE FIRST TIME A RECALL HAS EXCLUDED US. BOTH OF OUR VEHICLES HAVE HAD PROBLEMS IDENTICAL TO DEFECTS ON RECALLED AUTOS, BUT FOR SOME REASON THEY WILL NOT CHECK OUR VEHICLES. I BELIEVE THE PROBLEMS ARE THE SAME, BUT DUE TO FINANCIAL IMPLICATIONS THE MANUFACTURER IS TRYING TO LIMIT THE KNOWN AUTOS AS MUCH AS POSSIBLE. *AK
