I WAS COMING TO A STOP AND I LOST MY BRAKES I WAS ABLE TO GET IT STOPPED. TOOK IT TO MY MECHANIC RIGHT AWAY AND WAS TOLD THE BRAKE LINE BURST AND HIT MY GAS LINE BUSTING IT AS WELL. THEY HAD THE VEHICLE FOR OVER 3 WEEKS. THEY REPAIRED THE GAS LINE EASY ENOUGH BUT THE BRAKE LINE HAD TO BE COMPLETELY REPLACED. *TR
TL* THE CONTACT OWNS A 1999 GMC SIERRA. THE CONTACT STATED THAT WHILE DRIVING VARIOUS SPEEDS, HE SMELLED A STRONG GASOLINE ODOR INSIDE OF THE VEHICLE. THERE WAS ALSO FUEL VISIBLE ON THE GROUND. THE CONTACT INSPECTED THE VEHICLE AND NOTICED THAT BOTH THE FUEL AND BRAKE LINES WERE COMPLETELY RUSTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 71,000.
I WAS RETURNING FROM HUNTING TRIP ,AND WHEN I GOT OFF I-75 FREEWAY TO GO TO MY HOME TRAFFIC SIGNAL AHEAD WAS RED AND PEDAL WENT TO FLOOR. FORTUNATELY,THE LIGHT SWITCHED TO GREEN AND I WAS ABLE TO MANEUVER TO NOT COLLIDE WITH CAR STOPPED AHEAD. I NURSED IT HOME VIA BACK STREETS AT VERY LOW SPEED AND TO THE REPAIR SHOP THE NEXT MORNING. MECHANIC REPLACED BRAKE LINE. THE FUEL LINE WAS RUSTED OUT AT THE FUEL FILTER AND DISCOVERED WHILE OTHER MAINTENANCE WAS BEING PERFORMED. THE UNDERCARRIAGE IS EXTREMELY RUSTED AND I AM CONCERNED ABOUT PULLING MY TRAVEL TRAILER DUE TO RUSTY CONDITION OF THINGS. ROCKER PANELS ARE RUSTED OUT AS WELL AS REAR FENDER WELLS. SURELY GM CAN CONTROL CORROSION BETTER THAN THEY ARE DOING. SOMEONE IS GOING TO BE HURT OR KILLED DUE TO THESE VEHICLES RUSTING SO BADLY. *TR
TL* THE CONTACT OWNS A 1999 GMC SIERRA. WHILE DRIVING APPROXIMATELY 35 MPH ON A FOUR LANE HIGHWAY, THE CONTACT CAME TO AN ABRUPT STOP AND THE BRAKE PEDAL SUDDENLY TRAVELED TO THE FLOOR WITHOUT RESISTANCE. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE THE TECHNICIAN INFORMED THAT THE BRAKE LINE QUALITY WAS POOR WITH INEXPENSIVE MATERIALS. THE VEHICLE WAS REPAIRED AT THE COST OF $850. IN ADDITION, THE FUEL LINES EXHIBITED LEAKAGE DUE TO EXCESSIVE CORROSION WHICH WAS REPLACED ON A SEPARATE OCCASION. THE MANUFACTURER WAS NOTIFIED AND THEY STATED THAT THERE WERE NO COMPLAINTS FILED ON THE BRAKE LINE SYSTEM. THE FAILURE MILEAGE WAS APPROXIMATELY 60,200. THE VIN WAS UNAVAILABLE. UPDATED 06/16/11*LJ THE CONSUMER ALSO STATED THERE WAS A PROBLEM WITH THE FUEL LINES. UPDATED 06/21/11
FUEL PUMP/SENDING UNIT FAULTY. GAUGE DOES NOT READ PROPER FUEL LEVELS. ONE MINUTE WHILE GOING DOWN ROAD YOU HAVE A FULL TANK NEXT MINUTE LIGHT COMES ON FUEL GAUGE READS EMPTY. SOMETIMES GAUGE WILL NOT READ FUEL IN TANK AT ALL. I HAVE COME ACROSS OTHER GMC OWNERS WHO HAVE THE SAME COMPLAINT. GUYS AT SHOP SAY IT IS COMMON TO REPLACE THE FUEL PUMP/SENDING UNIT. *TR
THE FUEL GAUGE ON MY 1999 GMC SIERRA EXT. CAB DOES NOT WORK. IT HAS NEVER WORKED. I DID NOT SEE THE PROBLEM AS URGENT UNTIL MY BROTHER-IN-LAW, WHO HAS THE EXACT SAME TRUCK, GOT STRANDED IN MEXICO BECAUSE HIS FUEL PUMP WENT OUT. HE HAS HAD THE SAME PROBLEM SINCE HE HAS HAD HIS TRUCK AND IT COST HIM $300.00 DOLLARS TO CHANGE THE FUEL PUMP OUT. THAT WAS CHEAP BECAUSE HE DID THE WORK HIMSELF. I HAVE DONE SOME RESEARCH ON THE INTERNET AND HAVE SEEN THE SAME PROBLEM WITH SEVERAL TRUCKS OF THE SAME MODEL AND YEAR. I WENT TO THE LOCAL DEALERSHIP AND THERE IS NO RECALL ON THE FUEL PUMP FOR MY TRUCK AND WOULD RESPECTFULLY REQUEST THAT THE FUEL GAUGE/PUMP FOR THE 1999 GMC/CHEVY 1500 TRUCK BE LOOKED INTO FOR CONSIDERATION FOR A RECALL. *NM
DT*: THE CONTACT STATED THERE WERE TWO PROBLEMS WITH THE VEHICLE. FIRST, THE FUEL GAUGE WORKED INTERMITTENTLY, BUT THE VEHICLE HAS NOT BEEN INSPECTED BY THE SERVICE DEALER CONCERNING THIS ISSUE. THERE WERE NO WARNING INDICATORS PRIOR TO THE INTERMITTENT FAILURE OF THE FUEL GAUGE. SECOND, THE PASSENGER WINDOW DROPPED INTO THE DOOR WITHOUT WARNING. THE VEHICLE WAS INSPECTED BY THE CONTACT AND IT WAS DISCOVERED A CABLE WAS BROKEN THAT HELD THE WINDOW IN PLACE. A SHIM WAS ADDED TO KEEP THE WINDOW IN STATIONARY POSITION.
MY GAS GAUGE ON MY 1999 GMC SIERRA HAS NOT WORKED FOR OVER TWO YEARS. COST OF REPAIR TO HIGH. *NM
THE GAS GAUGE IN THE CONSUMER'S 1999 GMC SIERRA FAILED. CONSUMER FEELS THAT THE COST OF REPAIRING THE PART WAS TOO HIGH. THE CONSUMER HAS SPOKEN TO OTHER OWNERS WITH THE SAME PROBLEM AND BELIEVES THE MANUFACTURER SHOULD HAVE RECALLED THE PART. *NM *NM
FUEL GAUGE LOW FUEL LIGHT COMES ON INTERMITTENTLY EVEN AFTER JUST FILLING UP AND FUEL GAUGE BOUNCES ALL OVER THE PLACE. *NM
THE REAR STRAP THAT HOLDS THE GASOLINE TANK IN MY VEHICLE BROKE DUE TO CORROSION OF THE STRAP. THE TANK STAYED INPLACE UNTIL I COULD DRIVE TO THE DEALER TO HAVE IT REPLACED. THE DEALER WAS NOT CONCERNED AND ORDERED THE PART AND SCHEDUELD TO REPLACE IT IN A WEEK. *NM
DT: THE CONTACT STATED THAT THE FUEL GAUGE INDICATOR IWASNOT WORKING CORRECTLY. WHEN THE FUEL TANK WAS FILLED UP THE GAUGE WILL MOVE TO EMPTY, AND THE LOW FUEL LIGHT WILL COME ON. AFTER DRIVING THE VEHICLE FOR A WHILE THE GAUGE WILL MOVE TO FULL. BUT WITH CONTINUED DRIVING THE GAUGE WILL DROP DOWN TO EMPTY, AND THE FUEL LIGHT WILL COME ON AGAIN. THE SERVICE DEALER STATED THAT THE SENSOR NEEDED TO BE REPLACED. THE CONTACT HAD NOT REPLACED THE SENSOR. *AK
GAS TANK GAUGE WORKS ONCE IN A WHILE. OUR MECHANIC SAID IT WAS PROBABLY DUE TO MOISTURE. ALSO, THE REAR DIFFERENTIAL COVER IS EITHER CRACKING OR RUSTING THROUGH. I PUT A NEW GASKET ON IT AND THE NEXT DAY IT WAS LEAKING AGAIN BUT NOT AT THE GASKET. ABOUT 1/3 UP FROM THE BOTTOM, YOU CAN SEE WHERE FLUID IS LEAKING THROUGH THE COVER. I CALLED 2 DEALERS (1 CHEVROLET, 1 GMC). THEY BOTH GAVE ME NUMBERS TO OTHER DEALERS (1 IN PA., 1 IN IA., 1 IN UPPER MI.). THE TWO OUT OF STATE DEALERS TOLD ME THAT THE PART WAS FOR A CUSTOMER AND WOULD NOT SELL IT. THE ONE IN MI. ALSO SAID THAT, IN ADDITION TO "THAT MUST BE A POPULAR PART, BECAUSE I'VE HAD EVERY DEALER IN THE COUNTRY CALL ME." IS THIS PART A DEFECTIVE PIECE? *NM
TRUCK RUNNING SLUGGISH. DIFFICULT TO START AT TIMES. HOOKED UP TO COMPUTER A COUPLE TIMES AND SHOWED DIFFERENT SENSORS BAD AT DIFFERENT TIMES. DRIVING TO WORK ON 7/7/2005 VEHICLE SUDDENLY SHUTS DOWN, ABLE TO PULL INTO A RESTURANT PARKING LOT. PROBLEM : FUEL PRESSURE REGULATOR CLOGGED ( THIS IS A VACCUM LINE NO GAS SHOULD GO THROUGH IT) CAUSING GAS TO FLOW AT 60 POUNDS FUEL PRESSURE INTO THE INTAKE MANIFOLD CAUSING A FIRE. BECAUSE OF THIS THE MANIFOLD BURNED A BIG HOLE WHERE #4 CYLINDER WOULD BE LOCATED. THIS HAPPENED WHILE I WAS DRIVING 55 MPH DOWN THE ROAD & WAS POSSIBLY STILL BURNING WHILE I WAITED IN MY VEHILCLE TO BE PICKED UP. I BELIEVE THIS IS A DANGEROUS & SHOULD BE LOOKED AT. MY GIRLFRIENDS NEPHEW FOUND THE PROBLEM & REPLACED THE INTAKE MANIFOLD & FUEL PRESSURE REGULATOR. WHILE WORKING ON MY 99 GMC SIERRA HER BROTHER WHO DRIVES A 2000 GMC SIERRA DESCRIBES THE SAME PROBLEMS I WAS EXPERIENCING & PROMPTLY BRINGS OVER HIS TRUCK. UPON LOOKING AT HIS FUEL PRESSURE REGULATOR IT ALSO WAS FULL OF GAS ! HIS WAS FOUND EARLIER WITHOUT RESULTING IN FIRE & HIS FUEL PRESSURE REGULATOR WAS REPLACED. I CONTACTED GMC & THEY HAVE GIVEN ME A HARD TIME, BECAUSE THEY WANTED ME TO TAKE IT TO A GMC GARAGE, I WAS NOT GOING TO PAY TO HAVE IT TOWED THERE . BUT PLAN ON STOPPING THERE MONDAY 7/18/05 TO SHOW THEM THE PARTS ( I HAVE THE FUEL PRESSURE REGULATOR & THE INTAKE MANIFOLD WITH THE HOLE BURNT THROUGH)

THE FUEL GAUGE LOCATED ON THE DASHBOARD MALFUNCTIONED. THE LEVER FLUCTUATEED BETWEEN FULL AND EMPTY. THE ACCURATE AMOUNT OF FUEL IN THE TANK WAS UNKNOWN. TO CORRECT THIS FAILURE THE FUEL LEVEL SENSOR HAS TO BE REPLACED. THIS IS A COMMON FAILURE WITH THESE VEHICLES. *JB
