1999 GMC SIERRA 1500 Complaints

THE FIRST TIME I BOUGHT THE VEHICLE IT OVERFLOWED FUEL WHEN I FILLED THE FUEL TANK TO IT'S CAPACITY. I ASSUMED A VENT LINE WAS LOOSE, BUT KNEW IT WOULD BE A BIG JOB TO DROP THE FUEL TANK AND CHECK, SO I JUST LIMITED THE AMOUNT OF FUEL I WOULD FILL THE TANK WITH. ON JAN 5, 2007, THE FUEL PUMP QUIT WORKING AND AFTER DROPPING THE TANK NO VENT LINE WAS FOUND TO BE LOOSE. UPON FURTHER INVESTIGATION, I DETERMINED THE FUEL PUMP MOUNTING FLANGE ON THE TANK WAS ABOUT HALF CONNECTED, THUS WHERE THE FUEL WOULD LEAK FROM WHEN THE TANK WAS FILLED TO CAPACITY. IT APPEARED THE MOUNTING FLANGE IS FUSED ON AND THERE WAS NOT AN ADEQUATE BON MADE. IT WAS ON ABOUT 1/32" WIDE FOR 180 DEGREES AND ONLY ABOUT 1/16" WIDE THE OTHER 180 DEGREES. I HAVE SINCE REPAIRED THE TANK USING A PRODUCT CALLED JB WELD AND ALSO INSTALLING (4) #10 MACHINES SCREWS WITH WASHERS AND LOCKING NUTS HOLDING THE FLANGE TO THE TANK. *JB

AFTER THE WARRANTY RAN OUT AND AT ABOUT 60,000 MILES THE TRANSMISSION STARTED SHIFTING HARD FROM FIRST TO SECOND GEAR. THE CHECK ENGINE LIGHT STARTED COMING ON INTERMITTENTLY. WHEN THE ENGINE CODE WAS CHECKED IT WAS THE 1870 TRANSMISSION SLIPPAGE CODE. AFTER CHECKING ONLINE THERE WERE HUNDREDS OF OTHER CUSTOMERS WITH THE SAME PROBLEM. I TOOK IT TO THE DEALER AFTER THE CONDITION WORSENED AND THE DEALER RECOMMENDED REPLACING THE TRANSMISSION WITHOUT EVEN SEEING THE PROBLEM DUPLICATED. THIS SHOULD HAVE BEEN A RECALL ITEM YEARS AGO. I HAVE HAD TO REPLACE THE ELECTRONIC FUEL PUMP TWICE. ONLINE THERE WERE NUMBERS OF CUSTOMERS WITH THIS SAVE REPLACEMENT PROBLEM. I HAVE AN OLDER VEHICLE THAT HAVE NEVER HAD THE FUEL PUMP REPLACED. *NM

DT*: THE CONTACT STATED WHILE DRIVING 25 MPH, THE BRAKE PEDAL WAS MUSHY WHEN DEPRESSED, AND THE STOPPING DISTANCE WAS EXTENDED. THIS WAS ACCOMPANIED BY A CLACKING NOISE IN THE FRONT END. UPON INSPECTION, IT WAS NOTED THAT BRAKE FLUID WAS LEAKING FROM THE UNDERSIDE OF THE VEHICLE BELOW THE DRIVER'S SEAT. THE VEHICLE WAS NOT SEEN BY A DEALER FOR THIS INCIDENT, HOWEVER THE VEHICLE HAD PREVIOUSLY BEEN TAKEN TO A PRIVATE REPAIR SHOP, WHERE THEY NOTED THAT THE CALIPER FITTINGS AROUND THE BRAKE SHOES WERE CORRODED. THE BRAKE LINE FITTINGS WERE REPLACED, WHICH CORRECTED THE CORROSION. THE MANUFACTURER WAS ALSO NOTIFIED. THERE WAS A NHTSA RECALL# 00V345000, WHICH PERTAINS TO THE PIPING AND FITTINGS ON THE SERVICE BRAKES. THE VEHICLE WAS NOT INCLUDED IN THE RECALL DUE TO THE VIN.

DT*: THE CONTACT STATED WHILE BACKING THE VEHICLE OUT OF A PARKING SPACE, A HUMMING NOISE WAS HEARD. WHILE DRIVING THE VEHICLE 50 MPH, THE NOISE CONTINUED. THE CONTACT DETERMINED THE HUMMING NOISE WAS THE BRAKE MODULE PUMP RUNNING AND DISCONNECTED THE PUMP UNTIL THE VEHICLE COULD BE TAKEN TO THE DEALERSHIP. AFTER THE ENGINE WAS TURNED OFF, THE HUMMING NOISE CONTINUED. THE DEALERSHIP CONFIRMED THE HUMMING NOISE WAS COMING FROM THE BRAKE CONTROL MODULE AND THERE WAS EITHER A FAULTY ELECTRONIC COMPUTER RELAY IN THE BRAKE MODULE OR IN THE VALVE BODY OF THE BRAKE MODULE. UPDATED 10/18/2006 - THE CONSUMER IS CONCERNED THAT THE BRAKES MAY FAIL. *NM

MY ABS SYSTEM HAS FAILED THE MOTOR RUNS CONSISTENTLY BY THE PUMP UNDER THE DRIVERS SIDE DOOR, I PULLED THE WIRE CONNECTION HARNESS TO SILENCE IT AND NOW I HAVE A CONSTANT YELLOW ABS AND RED BRAKE LIGHT ON THE DASH PANEL. THE DEALERSHIP DID THE FRONT SENSOR RECALL BUT STILL HAVE THE EXISTING PROBLEM. THIS HAPPENED 3 YEARS AFTER I BOUGHT IT BUT MY WARRANTY WAS UP AFTER 1 1/2 YEARS BECAUSE OF MY DISTANCE FROM MY EMPLOYER ATE UP THE WARRANTY. *JB

DT*: THE CONTACT STATED WHILE APPROACHING A STOP SIGN AT 15 MPH, THE VEHICLE'S BRAKES FAILED. THE DEALERSHIP WOULD NOT ACCEPT THE VEHICLE BECAUSE THE SERVICE DEPARTMENT COULD NOT OFFER AN IMMEDIATE APPOINTMENT. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP WHO DETERMINED THE PLASTIC PROTECTION OF THE BRAKE FLUID LINE WAS NOT COMPLETELY COVERING THE LINE RESULTING IN A RUSTED LINE DUE TO CONDENSATION. BRAKE FLUID LEAKED FROM THE LINE CAUSING THE BRAKE FAILURE. *AK THE BRAKE LINE HAD SEVERE RUST. UPDATED 10/02/06. *JB

ON MY 2001 GMC SIERRA TRUCK THE WARNING LIGHTS CAME ON FOR THE ABS AND THE PARKING BRAKE I TOOK IT TO THE MECHANIC AND WAS TOLD THE EBCM (ELECTRONIC BRAKE CONTROL MODUL) NEEDS REPLACED. I SPOKE WITH THE MECHANIC AND HE POINTED OUT THAT THERE IS A LOT OF THESE BEING REPLACED ON THIS YEAR OF VEHICLE. *JB
