1999 Chevrolet Silverado complaints

WHEN SLOWING TO A STOP, BRAKE PEDAL STARTS TO PULSE, THEN ,ABS EFFECT KICKS IN AND DRIVERCANNOT STOP VEHICLE. BRAKES HAVE BEEN QUESTIONABLE FROM BEGINNING, HOWEVER WITHIN THE LAST 8 MONTHS HAVE BECOME INCREASINGLY UNSTABLE. DURING PAST MONTH, THERE HAVE BEEN 5 "NEAR MISSES" WITH OTHER CARS, GARAGE DOORS AND STATIONERY OBJECTS WHERE TRUCK HAS FAILED TO STOP.

AFTER SHUTTING OFF VEHICLE ABS PUMP KEPT RUNNING. DEALER STATED ABS PUMP HAD TO BE REPLACED.*AK

THE ANTILOCK BRAKE CONTROLLER FAILED. I TALKED TO THE DEALER HERE IN TUPELO, AND HE SAID THAT IT WAS OUT OF WARRANTY AND THEY WOULD NOT FIX IT UNLESS I PAID. I CHECKED ON THE COST AND THEY SAID THAT IT WOULD COST AROUND 950.00 BUT WOULD BE ABOUT A MONTH BECAUSE THEY ONLY HAD A COUPLE OF THE UNITS THAT WOULD FIT MY TRUCK AND THEY WERE KEEPING THEM ON HAND FOR WARRANTY CALLS. I ASKED THEM WHY THE LONG DELAY AND THEY SAID THEY WERE GOING OUT QUITE OFTEN. I CALLED GM CUSTOMER SERVICE TO INQUIRE AND WAS TOLD THEY WERE UNAWARE OF ANY PROBLEMS WITH THE ANTILOCK SYSTEMS ON MY YEAR OF TRUCK. THAT DID NOT SEEM TO BE THE SAME INFORMATION I RECEIVED FROM THE DEALER, SO I CALLED 7 MORE DEALERS IN THE SURROUNDING AREA AND TALKED TO THE SERVICE DEPARTMENTS. ALL I HAD TO DO WAS SAY THAT I WAS HAVING PROBLEMS WITH MY ANTILOCK BRAKES AND THEY SAID "OH IS THE PUMP RUNNING ALL THE TIME?" THEY SAID THAT WAS A VERY COMMON PROBLEM AND THEY HAD TO REPLACE THEM ALL THE TIME. I THEN THOUGHT THAT I WOULD SEE IF I COULD LOCATE A USED ONE IN A SALVAGE YARD AND REPLACE THE CONTROLLER MY SELF... I CALLED NUMEROUS SALVAGE YARDS AND FOUND QUITE A FEW OF 1999 SILVERADO'S BUT ALL OF THEM HAD ALREADY HAD THE CONTROLLER REMOVED. I THEN CALLED GM BACK AND TOLD THEM OF WHAT I HAD FOUND OUT, THEY WERE VERY NICE BUT IN EFFECT TOLD ME "TOUGH" SO I THOUGHT I WOULD WRITE TO YOU AND FILE MY COMPLAINT AND SEE IF YOU HAVE HAD ANY OTHERS.*AK

APPROXIMATELY ONE WEEK AGO I BEGAN NOTICING PROBLEMS ON ROUGH SURFACES WITH MY ANTI-LOCK BRAKES. WHENEVER THE BRAKES WERE APPLIED ON A ROUGH SURFACE THE ANTI-LOCK BRAKES ACTUATED BUT DIDN'T SEEM TO BE STOPPING THE CAR. I ATTRIBUTED THE PROBLEM TO BE SIMPLY A FUNCTION OF THE ROUGH SURFACE COMBINED WITH THE RAINY CONDITIONS AT THE TIME. YESTERDAY MORNING WHEN I STARTED MY VEHICLE THE ABS LIGHT CAME ON AND I IMMEDIATELY NOTICED A LOUD CLICKING NOISE WHICH CONTINUED EVEN AFTER TURNING OFF THE IGNITION. I HAD TO REMOVE THE 60 AMP FUSE FOR THE BRAKE SYSTEM TO STOP THE PUMP FROM ACTUATING. I TOOK THE VEHICLE TO THE DEALER AND WAS INFORMED THAT THE ELECTRONIC MODULE WHICH OPERATES THE SYSTEM HAD SHORTED OUT. THIS SAME PROBLEM HAS BEEN EXPERIENCED BY 6 OTHER PEOPLE I WORK WITH HERE AT EGLIN AFB.*AK

AFTER TURNING OFF VEHICLE THEY CAN STILL HEAR ABS ENGAGING. CAUSE UNKNOWN. DEALER NOTIFIED.*AK

THE EBCM (ELECTRONIC BRAKE CONTROL MODULE) FAILED, LEAVING ME WITH NO ANIT-LOCK BRAKES. I BELIEVE THIS IS DUE TO THE FACT THAT THEY MOUNTED THIS ELECTRICAL SYSTEM UNDERNEATH THE TRUCK (EXPOSED TO ALL ELEMENTS) RATHER THAN UNDERNEATH THE HOOD. IN FACT, CHEVROLET MUST BELIEVE THE SAME THING, BECAUSE THEY CHANGED THE DESIGN IN 2000 (THEY NOW PUT THIS COMPONENT UNDERNEATH THE HOOD). I KNOW THIS HAS HAPPENED TO MANY PEOPLE (SEE DISCUSSION THREAD "SILVERADO ABS MODULE FAILURE" ON HTTP://WWW.4X4REVIEW.COM/DISCUSSIONS/CHEVY/). FURTHERMORE, CHEVROLET WANTS TO CHARGE ALMOST $1800 TO FIX THIS ($711 FOR JUST THE PART, BUT SPECIAL TOOLS ARE REQUIRED TO CALIBRATE IT). I THINK THIS COST IS PROHIBITIVE (ALMOST 10% COST OF THE VEHICLE) TO MANY PEOPLE, CAUSING THEM TO NEGLECT THIS REPAIR AND GO WITHOUT ABS. THE CENTRAL POINT OF THIS COMPLAINT IS THAT THIS IS A DESIGN FLAW AND CHEVROLET REFUSES TO PROVIDE ANY COST ASSISTANCE.*AK.WATER CAN ALSO GET INTO THE HYDR, PUMP AND BRAKE DOWN THE BRAKE FUEL,CAUSING BRAKE FAILURE.

AT APPROXIMATELY 24,000 MILES THE STEERING COLUMN DEVELOPED A RATTLE THAT WAS LOUDER WHEN TURNING OR DRIVING ON BUMPY ROAD. DEALERSHIP REPLACED THE INTERMEDIATE STEERING MODULE AT APPROXIMATELY 26,000 MILES. THE SAME BEHAVIOR BEGAN OCCURING AT APPROXIMATELY 50,000 MILES. MECHANIC INDICATES THAT THE INTERMEDIATE STEERING MODULE HAS EXCESSIVE PLAY. MANUFACTURER DOES NOT ACKNOWLEDGE A PROBLEM, AND I HAVE STOPPED DOING BUSINESS WITH THE DEALERSHIP BECAUSE OF SHODY SERVICE.*AK

CONSUMER STATES VEHICLE HAS STALLED 3 TIMES WITHIN THE LAST 18 MONTHS FOR NO REASON, THE VEHICLE STOPS PULLING AS IF THE TRANSMISSION HAS LOST ITS POWER TRAIN.(IDC CONSULTING, LEONARD PHILANDEZ ON BEHALF OF CONSUMER).*JB

THE ABS MODULE STARTED RUNNING WHEN IT DID NOT NEED TO BE AND WOULD NOT SHUT OFF. I CONTACTED SERVICE DEPARTMENT AT MOLLE CHEVROLET IN BLUE SPRINGS, MO, AND THEY KNEW EXACTLY WHAT THE PROBLEM WAS BECAUSE THEY HAD SEEN THE SAME THING SEVERAL TIMES BEFORE. THEY WANTED AROUND $1000 TO FIX IT. I FEEL LIKE GM NEEDS TO RECALL THIS COMPONENT IF IT IS FAILING WITH SUCH HIGH FREQUENCIES. I DON'T FEEL AS SAFE DRIVING WITHOUT ABS ESPECIALLY IN A PICKUP WHICH IS LIGHT ON THE REAR END AND CAN SLIDE EASILY IN AN EMERGENCY SITUATION.*AK

STICKING ACCELERATOR PROBLEM STARTED LESS THAN 20,000 MILES. ACCELERATOR LINKAGE NEEDS TO BE REPLACED . ACCELERATOR PEDAL HAS TO BE MASHED WITH EXCESSIVE FORCE TO BECOME UNSTUCK WHICH INCREASES UNINTENDED SPEEDS. DEALER WAS NOTIFIED. *AK JG

I ALREADY FILLED OUT A VEHICLE OWNER'S QUESTIONNAIRE TO SEND THROUGH THE MAIL WITH MY SIGNATURE TO AUTHORIZE NHTSA TO PROVIDE A COPY OF THE REPORT TO THE MANUFACTURER. REFERENCE NO. 8008990. I INCLUDED A COPY OF A RECALL NOTICE ON THE 2000 CHEVROLET SILVERADO 1500. THE RECALL STATES: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ABS MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL. THE BASE BRAKES WOULD REMAIN FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING SYSTEM (DRP), WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE. THIS IS THE SAME MALFUNCTION MY 1999 SILVERADO 1500 HAS. THE ABS SYSTEMS ARE IDENTICLE IN THE 1999 AND 2000 SILVERADO. THE REPLACEMENT PART NUMBER IS THE SAME FOR A 1999 AND A 2000. I DON'T BELIEVE THIS IS A COINCIDENCE, THAT THIS PART HAS FAILED IN MY 1999, WHEN IN FACT THIS IS THE SAME PART IN THE 2000'S THAT WERE RECALLED.*AK
