FUEL/PROPULSION SYSTEM
ON THE DURAMAX DIESEL, WHILE UNDER A LOAD (TOWING, FULL BED) FUEL LINES COLLAPSE CAUSING SEVERAL CHECK ENGINE LIGHTS AND VEHICLE TO GO INTO "LIMP" MODE. MUST RELEASE VACUUM IN FUEL SYSTEM (BY LOOSENING THE FUEL FILTER THEN RE-BLEEDING THE FUEL SYSTEM) IN ORDER FOR THE CODE TO GO OFF. HAPPENED SEVERAL TIMES, ONCE WHILE TOWING UP HILL. IF THIS HAD CAUSED AN ACCIDENT, I WOULD HAVE BEEN A GM SHARE HOLDER. VEHICLE HAS STALLED OUT SEVERAL TIMES IN THE WINTER DUE TO A COMBINATION OF THE WINTER DIESEL AND THE VACUUM FUEL SYSTEM. ONCE WHILE ON AN ICY ROAD, ON MY WAY TO WORK AT 4AM. GM NEEDS TO RECALL THIS. *TR

THE FRONT BUMPERS PLASTIC FOG LIGHT ASSEMBLY BECOMES LOOSE AND FALLS OFF. THIS CAN CAUSE CRASH AND ACCIDENT BECAUSE OF FALLING OFF PARTS FROM CAR. THIS SEEMS TO BE A KNOWN ISSUE WITH THE PLASTIC BUMPER PARTS FOR THE FOG LIGHTS. THE SUGGESTION IS TO REPLACE THIS WITH A CHROME OR METAL BUMPER SO THAT PLASTIC PEACES DO NOT BECOME WARPED AND BREAK OFF. THIS HAPPENS AT THE BOLT POINTS FOR THE FRONT BUMPER FOG LIGHT HOLDER ENTIRE PLASTIC PEACE. *TR

SERVICE BRAKES
THIS IS THE SECOND TIME A BRAKE LINE HAS BURST ON THIS TRUCK. THIS IS DANGEROUS. I HAD THE TRUCK TAKEN TO LOCAL SHOP AND WAS TOLD ALL BRAKE LINES ARE IN DANGER OF RUPTURE. HOW CAN GMC PUT THIS JUNK STEEL IN THEIR BRAKE LINES? WHEN PEOPLE START GETTING KILLED IF THEY HAVENT ALREADY MAYBE SOMETHING WILL BE DONE. I SMELL SOME LAWYER GETTING RICH HERE. *TR

FUEL SYSTEM, DIESEL
I HAVE A 2009 GMC SIERRA 2500HD 4X4 AUTOMATIC DIESEL LMM. WHILE TOWING MY TRAVEL TRAILER ON THE FREEWAY AT 65MPH THE DASHBOARD DISPLAYED THE MESSAGE "ENGINE POWER REDUCED" ALL OF A SUDDEN. WHILE THIS WAS BEING DISPLAYED THE VEHICLE SLOWED RAPIDLY TO 35MPH AND THE VEHICLES BEHIND ME WERE SCRAMBLING TO MOVE OVER. I LIMPED THE VEHICLE TO THE NEAREST EXIT AND CONNECTED MY OBDII READER AND IT DISPLAYED THE CODE OF P0087 LOW FUEL RAIL PRESSURE. I LIMPED THE VEHICLE TO THE NEAREST AUTO PARTS STORE AND CHANGED THE FUEL FILTER AS A PRECAUTION. I WAS ABLE TO LIMP THE VEHICLE HOME THE REST OF THE WAY WITHOUT ANY FURTHER ISSUES BUT THE REMAINDER OF MY COMMUTE WAS DOWN HILL - LUCKILY. I WOULD LIKE TO KNOW IF THERE IS ANY FURTHER INFORMATION ON THIS AND WHAT THE MANUFACTURER IS GOING TO DO IF AT ALL. *TR

SERVICE BRAKES
SLOWING FOR TRAFFIC LIGHT GOING DOWNHILL AND BRAKE PEDAL WENT TO FLOOR. PUMPING DID LITTLE SO USED PARKING BRAKE TO STOP. CLOUD OF WHITE SMOKE OUT OF TAIL PIPE AS ENGINE SHUTTERED AND VALVES CHATTERED. FRONT DRIVERS SIDE BRAKE LINE FAILED FROM EXTERNAL CORROSION SHOOTING FLUID ON HOT EXHAUST MANIFOLD. WHEN PEDDLE WENT TO FLOOR MASTER CYLINDER PASSED FLUID INTO BOOSTER AND THROUGH VACUUM LINE INTO INTAKE OF ENGINE CAUSING WHITE CLOUD OF BRAKE FLUID BURNING WITH GAS INTERNALLY ALMOST SHUTTING MOTOR DOWN AND LOSS OF ALL POWER. REPLACED CORRODED BRAKE LINES AND MASTER CYLINDER. NEGLIGENT DESIGN AND MATERIALS QUALITY IN MY OPINION. NOW BOTH FRONT CALIPERS DRAG AND SHAKE STEERING WHEEL. WHERE IS SAFETY RECALL? BRAKE LINES ARE NOT A MAINTENANCE ITEM! TRY REPLACING ONE AS THEY WERE INSTALLED TO NEVER COME OFF. WOULD TOYOTA HAVE BEEN GIVEN A PASS ON THIS ISSUE FOR THIS MANY YEARS OF COMPLAINTS, THOUSANDS OF FAILURES, INJURIES AND DEATHS? *TR

ELECTRICAL SYSTEM
WILL HAPPEN INTERMITTENTLY, AS DESCRIBED BY OTHER GMC OWNERS. SEE SIMILAR ISSUE WITH OTHER OWNERS AT THIS ADDRESS: HTTP://WWW.GM-TRUCKS.COM/FORUMS/TOPIC/129454-MY-FIX-ON-MY-SILVERADO-ELECTRICAL-PROBLEM/?HL=STALLING SEE ALSO: NHTSA REFERENCE #10036550 TSB REFERENCE #PIT-4730A VEHICLE IS UNMODIFIED. THE ISSUE IS WITH THE BATTERY CABLES AND ATTACHMENT TO THE FRAME AND FUSE PANELS. AFFECTS A WIDE VARIETY OF GM AND CHEVY MODELS, AND SHOULD DEFINITELY HAVE A RECALL, AS THIS CAUSES A VERY DANGEROUS SITUATION. WHAT HAPPENS IS : 1. TRUCK WILL BE RUNNING FINE, AS IT SHOULD. INTERMITTENTLY, WITHOUT WARNING WILL START HAVING DOOR LOCKS GO UP AND DOWN, ALONG WITH CHECK ENGINE LIGHTS, GAUGE CLUSTER RESETTING AND COMPLETE POWER LOSS TO THE ENGINE AND COMPONENTS (POWER STEERING, BRAKES, ETC.) 2. UPON SHUTTING OFF ENGINE EXPERIENCING FULL POWER LOSS. CANNOT CRANK ENGINE UNTIL POWER HAS BEEN RESTORED BY POPPING HOOD AND WIGGLING BATTERY TERMINAL CABLES. THE REASON WHY THIS IS DANGEROUS AND SHOULD HAVE AN IMMEDIATE RECALL, IS FIRST, WHEN THIS HAPPENED I WAS TRAVELING AT 80MPH. THE VEHICLE COMPLETELY SHUT OFF, CAUSING ME TO HAVE TO GUIDE TO THE SIDE OF THE ROAD WITHOUT THE ABILITY TO USE BLINKER, POWER STEERING, OR POWER BRAKES. I HAVE COMMUNICATION WITH OTHER GM OWNERS OF THE SAME YEAR RANGE, BUT AFFECTING MULTIPLE GM AND CHEVY MODELS. (ONE IS 2009 YUKON, DESCRIBING THE SAME ISSUES.) I KNOW THAT THIS COMPLAINT HAS BEEN ISSUED BY OTHER PEOPLE AS WELL. IT IS TIME FOR ACTION. *TR

SERVICE BRAKES
WHILE DRIVING I NOTICED SMOKE COMING FROM UNDER THE HOOD AND A FLUID DRIPPING ONTO THE FLOOR OF THE TRUCK. THEN THERE WAS ABSOLUTELY NO BRAKES. PEDAL TO THE FLOOR. I WAS ABLE TO GET IT INTO A PARKING LOT AND COASTED IN NEUTRAL TIL IT STOPPED ON A PARKING CURB. THE BRAKE LINE HAD RUSTED THROUGH AND RUPTURED, AND THE FLUID WAS SPRAYING INTO A HOLE IN THE FIREWALL AND INTO THE CAB OF THE TRUCK. THIS IS THE THIRD BRAKE LINE THAT HAS RUPTURED IN SUCH A MANNER. NO WARNING AT ALL, AND THEN SUDDEN LOSS OF BRAKING. THE WARNING LIGHT DID NOT COME ON UNTIL THE TRUCK HAD BEEN SITTING FOR OVER AN HOUR WHILE I WAS WAITING FOR A TOW, AND A LARGE AMOUNT OF FLUID HAD LEAKED OUT. I'M JUST GLAD THIS HAD HAPPENED AT A LOW SPEED AND NOT ON AN EXIT RAMP FROM THE FREEWAY. THE RUPTURES ARE OCCURRING WHERE THE LINES RUN FLAT ACROSS A SUPPORT. THIS IS A POOR DESIGN. *TR
