• 12/29/2014· SERVICE BRAKES

  I WAS TRAVELING AT 35 MPH AND APPROACHED A STOP LIGHT. THE BRAKES FAILED AND I WENT THROUGH THE RED LIGHT. I NEARLY WAS HIT BY ONCOMING TRAFFIC. THE BRAKE LINE HAS A SEVER LEAK AT A RUSTED AREA IN THE LINE. *TR

• 12/29/2010· ELECTRICAL SYSTEM

  SPEEDOMETER FAILED AT 68,000 MILES. IT STICKS ALL THE WAY PAST 120 MPH. CAN'T SEE HOW FAST I'M GOING, DEALER REFUSES TO FIX IT. TRIED THREE DEALERS. *TR

• 12/29/2006· STEERING,SERVICE BRAKES, HYDRAULIC

  TRUCK HAS BEEN IN DEALER NUMEROUS TIMES FOR SEVERE NOISE OF POWER STEERING PUMP, LOSS OF BRAKE BOOST AND STEERING ASSIST AT LOW SPEEDS. PUMP WAS REPLACED AND NOISED DISAPPEARED FOR JUST OVER 2 WEEKS AND STARTED AGAIN. DEALER EXPLAINED THAT GM IS AWARE OF PROBLEM, BUT IS ONLY TAKING CALLS ABOUT THE PROBLEM FROM ONE AREA CODE WHILE THEY TRY TO ISOLATE. DEALER THEN REPLACED THE STEERING GEAR WITH NO CORRECTION OF PROBLEM. AT A STANDSTILL, TURNING THE STEERING WHEEL ABOUT 3/4 TURN RESULTS IN COMPLETE LOSS OF STEERING ASSIST AND SOMETIMES BRAKE BOOST, PLUS EXCESSIVE PUMP NOISE. DEALER IS NOW TRYING TO TELL ME THIS IS NORMAL. THERE IS A TECHNICAL BULLETIN ON THIS PROBLEM. GM HAS INSTRUCTED DEALERS NOT TO REPLACE THE POWER STEERING PUMP. AS THEY HAVE RECEIVED TOO MANY PUMPS UNDER WARRANTY THAT APPEAR TO HAVE NO PROBLEM. DRIVING THE VEHICLE AT 1200 RPM AND STEERING RIGHT OR LEFT WILL GENERATE A GROANING NOISE THAT DROWNS CONVERSATION IN THE CAB AND AT TIMES RESULTS IN REDUCED OR FAILED BRAKE BOOST. THE SAME LOUD GROANING NOISE OCCURS WHEN SLOWING THE VEHICLE FROM HIGHWAY SPEEDS WITHOUT ANY TURNING OF THE STEERING WHEEL, AS THE ENGINE RPM FALLS THROUGH THE 1200 RPM RANGE. SOUNDS LIKE A HYDRAULIC SYSTEM WITH AIR IN THE SYSTEM, LOW FLUID OR BEING PUSH TO OVER-CAPACITY. GM IS NOT BEING RESPONSIVE TO THE EXCESSIVE NUMBER OF CUSTOMER COMPLAINTS. I KNOW OTHERS WITH THE SAME PROBLEM ON SEVERAL YEARS OF 2500HD DURAMAX TRUCKS. IT IS NOT AT ALL DIFFICULT TO FIND OTHERS WITH THIS EXACT SAME COMPLAINT. THE NOISE APPEARS TO BE AN UNDER CAPACITY HYDRAULIC SYSTEM FOR POWER STEERING AND BRAKE BOOST. GM IS EITHER IGNORING THE PROBLEM OR HOPING THE PROBLEM TRUCKS WILL EXPIRE WARRANTY. MORE OWNERS NEED TO COMPLAIN AND FORCE A RECALL TO REPAIR THIS DEFECT IN DESIGN. CONTRARY TO MY DEALER'S ASSERTION, THIS IS NOT NORMAL. I HAVE BEEN DRIVING LONG ENOUGH TO KNOW "NORMAL" AND A "PROBLEM DODGE" WHEN I SEE IT.

• 12/28/2014· SERVICE BRAKES

  AROUND THE MIDDLE OF DECEMBER 2014 THE "SERVICE BRAKE SYSTEM" MESSAGE APPEARED ON MY 2005 GMC 1500 SIERRA SLE. I CHECKED THE BRAKE FLUID RESERVOIR AND IT WAS NEARLY EMPTY. I COULD NOT FIND WHERE THE FLUID HAD LEAKED FROM SO I SERVICED THE RESERVOIR WITH 12 OUNCES BRAKE FLUID TO THE FULL MARK. FROM ABOUT DECEMBER 15, 2014 UNTIL 28 DECEMBER 2014, I LOST ABOUT 7 OUNCES OF BRAKE FLUID. NO TRACE OF BRAKE FLUID CAN BE FOUND ON THE DRIVEWAY. I CRAWLED UNDER THE TRUCK AND HAD MY WIFE PRESS THE BRAKES WHILE I LOOKED FOR A LEAK. I FOUND THE LEAK NEAR THE LEFT REAR WHEEL AREA ON A VERY CORRODED BRACKET. IT APPEARS TO BE A VERY SMALL HOLE BECAUSE THE FLUID COMES OUT AS A FINE MIST AND NOT A STREAM. THE RIGID BRAKE LINE CONNECTS TO A FLEXIBLE BRAKE LINE AT THE BRACKET AND THERE IS A LOT OF RUST AT THE CONNECTION AS WELL AS THE BRAKE LINE. I HAVE FOUND RUST FORMING ON OTHER BRAKE LINES AS WELL. *TR

• 12/11/2017· SERVICE BRAKES,ENGINE,FUEL/PROPULSION SYSTEMCrash

  COMPLAINT ON GM EXHAUST MANIFOLD BOLT DEFECT, INFERIOR BRAKE/ FUEL LINES. MINE IS A 2005 GMC. DEFECTIVE EXHAUST BOLTS AFFECT 12 MILLION GM TRUCKS FROM 1999 TO 2007. GM EXHAUST BOLTS ARE TO SMALL BRITTLE FOR SECURING EXHAUST MANIFOLDS. BOLTS SNAP OFF CAUSING EXHAUST LEAKS. TRUCKS NOT PASSING EMISSIONS AND DANGEROUS EXHAUST FUMES ENTERING THE DRIVERS COMPARTMENT OF THE VEHICLES WHILE DRIVING. I AND MY FAMILY GET A CARBON MONOXIDE HEADACHE WHEN I DRIVE IT AND HAVE HAD TO PULL OVER TO THE SIDE OF THE ROAD FEELING LIKE I WAS GOING TO PASS OUT, OPEN WINDOWS AND SIT UNTIL I FELT BETTER. I HAVE ALSO HAD PROBLEMS GETTING MY TRUCK TO PASS EMISSIONS DUE TO THE LEAKS AND THE LEAKS ARE CAUSING THE VEHICLES TO BE NONE EPA COMPLIANT BECAUSE OF O2 SENSOR ERRORS RESULTING IN FAILED EMISSION TEST. ALSO BRAKE AND FUEL LINES ARE NOT SUITABLE FOR NORTHERN STATES CAUSING BRAKE FAILURE WITH OUT WARNING, FUEL LINES ARE ALL RUSTED AND SWELLED IN DANGER OF BURSTING CAUSING FIRE WITHOUT WARNING. FORD AND OTHER VEHICLES I HAVE WORKED ON USE STAINLESS FUEL LINES AND LOOK LIKE NEW FOR LIFE OF VEHICLE. I HAVE ALSO SEEN OTHER MANUFACTURERS USE POWDER COATED BRAKE LINES ON THE ENTIRE VEHICLE AND 20 YEAR OLD VEHILCES SHOW NO RUST PROBLEMS. MY 2005 GMC FROM THE REAR END BRAKE HOSE TO THE WHEEL CYLINDERS THEY USED POWDER COATED BRAKE LINES. THOSE LINES LOOK LIKE NEW YET. GM KNEW THE POWDER COATED LINES WERE BETTER WHY DID THEY USE FAULTY GALVANIZED STEEL ON THE REST OF THE TRUCK? AS IT IS NOW MY TRUCK CAN'T BE OPERATED ON THE ROAD WITHOUT $3000 IN REPAIRS DUE TO GM USING POOR QUALITY PARTS. THE TRUCK HAS HAD THESE PROBLEMS FOR OVER 5 YEARS NOW AND ONLY HAS 138,000 MILES. TRUCKS LIKE THIS IN SOUTHERN STATES HAVE OVER 250,000 MILES, LINES STILL GOOD. RECALL NEEDS TO BE DONE.

• 12/11/2013· ELECTRICAL SYSTEM,SEATS

  THE DRIVER SEAT HEATER RANDOMLY TURNS ON BY ITSELF. IT RANDOMLY SWITCHES FROM THE SEAT TO THE BACK OF THE SEAT TO BOTH AT THE SAME TIME, IN NO PARTICULAR ORDER. WHEN I TURN IT OFF IT JUST COMES RIGHT BACK ON AGAIN. I HAD THE MODULE IN THE DOOR REPLACED ONE TIME, BUT IT STILL DOES IT. I LIVE IN THE SOUTH, SO IT'S EXTREMELY UNBEARABLE DURING THE SUMMER MONTHS. I WILL GO FOR WEEKS AT A TIME WHEN IT DOESN'T DO IT, BUT THEN IT JUST SEEMS TO START AGAIN. THERE REALLY DOES NOT SEEM TO BE ANYTHING IN PARTICULAR THAT TRIGGERS IT. I THOUGHT MAYBE IT WAS GETTING WET WHEN IT RAINS, BUT SINCE I LIVE IN THE SOUTH WE HAVE HIGH HUMIDITY 95% OF THE TIME, SO WE HAVE MOISTURE PROBLEMS HERE ALL THE TIME. I CAN GO FOR WEEKS THAT IT DOESN'T HAPPEN, THEN IT JUST STARTS UP AGAIN. I HAVE SEARCHED THE PROBLEM ON GOOGLE AND FOUND THAT OTHER PEOPLE COMPLAIN ABOUT THE SAME PROBLEM WITH THIS PARTICULAR MODEL, BUT I CAN NOT FIND A SAFETY RECALL ISSUED BY GMC. *TR

  I HAVE HAD THE BRAKES GO OUT 3 DIFFERENT TIMES ON ME IN THE LAST YEAR. THERE ARE NO SIGNS OF PROBLEMS AND YOU STEP ON THE BRAKES AND A LINE BLOWS. YOU HAVE NO BRAKES PEDDLE GOES TO THE FLOOR AND LITTLE TO NO STOPPING. ONE TIME I WAS COMING DOWN A DIRT ROAD TO A STOP SIGN AND STEPPED ON THE BRAKES AND A LINE BLEW AND THE ABS KICKED IN BECAUSE OF THE DIRT ROAD AND I COULD NOT STOP AND WENT RIGHT THROUGH A INTERSECTION. THEY USED CHEAP LINES, AND NOW PEOPLE IN THE NE WHERE SALT IS USED ARE HAVING PROBLEMS. I COULD HAVE BEEN KILLED.THE LINE RUSTY OUT WHERE THEY BEND AND SALT AND DIRT BUILD UP. THERE IS NO REASON THEY CAN NOT MAKE THESE LINES OUT OF SS OR AS WITH THE NEWER LINES THEY ARE COATED. WHY COME OUT WITH A COAT LINE IF THERE IS NOT A PROBLEM. *TR

• 12/06/2015· SERVICE BRAKES

  ON 11-30-2015 I LOST THE BRAKE SYSTEM WHILE DRIVING ON A CITY STREET. UPON INSPECTION I FOUND A RUPTURED BRAKE LINE FROM THE PRIMARY SIDE OF THE MASTER CYLINDER. THE BRAKE LINE HAD FAILED DUE TO CORROSION. INSPECTING OTHER BRAKE LINES, I FOUND OTHERS THAT HAD CORROSION WHERE PLASTIC CLIPS WERE USED TO LOCATE LINES. I HAVE OWNED THIS TRUCK SINCE NEW AND HAVE CARED FOR IT METICULOUSLY. THE TRUCK HAS 66,00 MILES ON IT. I HAVE NEVER OWNED ANY VEHICLE THAT HAD IT BRAKE LINES RUST THROUGH LIKE THIS. A MAJOR CATASTROPHE TO ME AND MY FAMILY WAS AVERTED BY PULLING OVER AT THE FIRST SIGN OF FAILURE. GM SHOULD BE HELD LIABLE FOR EVERY VEHICLE IT MANUFACTURED WITH POOR QUALITY MATERIALS THAT CAN CAUSE FAILURE TO THE SINGLE MOST IMPORTANT PART OF AN AUTOMOBILE, THE BRAKES. AS YOU CAN SEE FROM THE ATTACHED PHOTOS, THIS TRUCK IS NOT RUSTED ANYWHERE ELSE.
