SERVICE BRAKES
MY 2006 GMC HAS ONLY 29,000 MILES ON IT. I BOUGHT THE TRUCK IN OCTOBER 2009 WITH 16,000 MILES. I KEEP THE TRUCK CLEAN INSIDE AND OUT, TOP TO BOTTOM INCLUDING UNDER THE VEHICLE. PEOPLE COMMENT TO ME ALL THE TIME ON HOW NICE THE TRUCK LOOKS. BRAKE LINE LET GO IN YARD. PEDAL WENT TO THE FLOOR, NO BRAKES HAD TO HIT REVERSE THEN NEUTRAL AND THE EMERGENCY BRAKE. I HAD JUST RETURNED HOME FROM GOING UP TOWN. THANK GOD IT HAPPENED WHERE IT DID. I HAVE BEEN DRIVING 40 YEARS AND ONLY REPLACED ONE BRAKE LINE IN A 11 YEAR OLD FORD TRUCK AND THAT WAS JUST A SECTION NEAR A BEND. THIS TRUCK NEEDS TO HAVE ALL THE LINES REPLACED. I JUST REPLACED ALL THE TRANSMISSION LINES 4 MONTHS AGO FOR $800.00. SAME THING, ALL RUSTED. I LIVED IN MASSACHUSETTS MY WHOLE LIFE AND I DO MY BEST TO KEEP THE SALT OFF THE TRUCK. LAST TIME I EVER SEEN RUST ISSUES THIS BAD WAS IN THE 1970S WHEN CARS WOULD START RUSTING OUT AFTER 3 YEARS BECAUSE OF THE REUSED STEEL THAT CAME FROM OVERSEAS. *TR

VISIBILITY/WIPER, EXTERIOR LIGHTING
THE HEADLIGHT PERFORMANCE ON THIS TRUCK IS THE WORST I'VE SEEN IN ANY VEHICLE, BUT FOR A TRUCK, I CANNOT BELIEVE THEY ARE ALLOWED ON THE ROAD AT NIGHT. THE OWNER'S MANUAL STATES THEY ARE FACTORY SET AND DO NOT NEED ADJUSTMENT. THAT INFORMATION WAS OBVIOUSLY NOT CHECKED DURING THE QUALITY CHECK OR CHECKED BUT FELT IT WAS AS GOOD AS IT GETS. ON HIGH BEAM, THE DRIVER'S SIDE LIGHT IS POINTING SO FAR UP, IT'S IN THE TREES AND ABOVE THE ROAD. THE RIGHT SIDE HIGH AND LOW BEAMS ARE INADEQUATE FOR ALL PURPOSES, ESPECIALLY SEEING AROUND CURVES AND TURNS. YOU ARE LITERALLY BLIND ON A DARK STREET, EVEN WITH THE FOG LIGHTS. VERY POOR ILLUMINATION OF THE ROAD. I'VE TAKEN IT IN TO THE DEALER FOR ADJUSTMENT AND THEY DID NOT CHANGE ANYTHING. THIS WILL BE THE LAST GM PRODUCT I BUY SINCE IT SEEMS THE LAST THREE VEHICLES I'VE OWNED HAD ISSUES THAT COULD NOT BE RESOLVED. AND I AM A MEMBER OF THE GM FAMILY. FOR THE PRICE OF THESE VEHICLES, THEY SHOULD BE TOP QUALITY. GM SHOULD BE ASHAMED OF THE QUALITY THEY DELIVER TO CUSTOMERS FOR VEHICLES PRICED OVER $45K. *TR

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

DRIVER SIDE AIR BAG EXPLODED. THE BAG ITSELF DID NOT DEPLOY. JUST A LOUD EXPLOSION FILLING THE CAB WITH BLACK SMOKE. VIOLENT BLAST OF AIR/SMOKE AGAINST THE DRIVER. WOULD HAVE BEEN VERY SERIOUS IF NOT DRIVING AT LOW SPEED ON A SIDE ROAD AT THE TIME. *TR

SERVICE BRAKES
I OWN A 2013 GMC SIERRA 4WD CREW CAB THAT IS HAVING BRAKING PROBLEMS. I PURCHASED THE VEHICLE ON 05/29/2013 NEW FROM BILL SMITH BUICK-GMC INC. LOCATED IN CULLMAN, AL AS A NEW VEHICLE AND AT THE TIME OF PURCHASE IT HAD 7173 MILES ON IT AS STATED ON THE ODOMETER DISCLOSURE STATEMENT. THE VEHICLE CURRENTLY HAS 41585 MILES ON IT THAT INDICATED I HAVE DRIVEN THE VEHICLE 36412 MILES. I HAVE HAD TWO INCIDENTS WITH THE BRAKES WHERE THE VEHICLE FAILED TO STOP WITH THE BRAKES FULLY APPLIED. THE FIRST TIME WAS WHEN THE VEHICLE HAD APPROXIMATELY 15000 MILES ON IT. THE SECOND TIME OCCURRED THIS PAST THURSDAY, DECEMBER 18, 2014 WHEN I APPLIED THE BRAKES AT 25 MPH AND THE CAR JUST CONTINUED TO ROLL UP HILL UNTIL I HIT A CAR IN FRONT OF ME. THERE WAS NO DAMAGE TO THE OLDER BUICK LASABER REAR END OR BUMPER BUT MY FRONT BUMPER WAS PUSHED IN ABOUT 2 INCHES. IF I HAD BEEN ON THE LEVEL OR WAS GOING ABOVE 25 MPH I SUSPECT THERE WOULD HAVE BEEN SUBSTANTIAL DAMAGE TO BOTH VEHICLES. WHAT?S HAPPENING IS WHEN THE BRAKE IS APPLIED THE CAR STARTS TO SHUDDER AND SOUNDS LIKE YOUR BANGING ON A TIN CAN. WHEN THAT HAPPENS THE TRUCK IS NOT STOPPING OR SLOWING AT ALL AND THE BRAKE PEDAL IS AS FAR DOWN AS IT CAN GO. PUMPING THE BRAKE WILL CAUSE THE BRAKES TO RECOVER AND THE VEHICLE WILL STOP. THIS PROBLEM HAS NOT BEEN A CONSISTENT ISSUE. THIS LAST THURSDAY IS THE FIRST TIME I COULDN?T STOP IN 26000 MILES. BACK WHEN THE VEHICLE HAD 15000 MILES ON IT THE SAME THING OCCURRED. WHILE DRIVING THE VEHICLE TO WORK THIS MORNING AFTER PICKING IT UP FROM THE GMC DEALERSHIP THAT SAID THERE WAS NOTHING WRONG IT HAPPENED AGAIN. THIS WAS AFTER MAKING SEVERAL STOPS ON HWY 280 IN BIRMINGHAM, AL. THIS TIME I RAN THE RED LIGHT WITH NO CONSEQUENCES BUT MY LUCK WILL NOT CONTINUE. *TR

FUEL SYSTEM, GASOLINE
BEGAN TO SMELL FAINT RAW GAS FUMES AROUND THE VEHICLE IN THE SUMMER. IN THE AUTUMN MONTHS THE RAW GAS ODOR SMELL INTENSIFIED AND WAS VERY STRONG WITH AN OVERCOMING PRESENCE IN THE CABIN WHILE DRIVING. I BROUGHT THE VEHICLE TO MY SHOP FOR DIAGNOSTIC. THE MECHANIC (NON GMC GARAGE) CALLED BACK SEVERAL HOURS LATER AND SAID I HAD BEEN DRIVING A POTENTIALLY DISASTER. HE ASKED ME TO SEE FOR MYSELF. I WAS ABLE TO VIEW THIS FIRST HAND AFTER HE HAD REMOVED THE FUEL TANK FROM THE VEHICLE. THE FUEL PUMP IS MOUNTED INTO A DEEP SUMP ON THE TOP OF THE GAS TANK. THE SUMP WELL IS RATHER DEEP AND COLLECTS MUD, SILT, DEBRIS AND WATER WHILE DRIVING AND THAT COLLECTS AND BUILD UP OVER TIME INTO THE SUMP AND THAT STAYS MOIST AT ALL TIMES. OVER THE COURSE OF 6 YEARS THE FUEL PUMP HOUSING AND MOUNT RING RUSTED, ROTTED OUT AND STARTED LEAKING RAW GAS THAT WAS SPILLING ONTO THE HOT EXHAUST PIPE ALONGSIDE THE FUEL TANK. I DO NOT GO OFF ROAD WITH THE VEHICLE NOR DO I PLOW SNOW WITH IT. THE VEHICLE IS USED PRINCIPALLY IN HIGHWAY DRIVING. A FEW WEEKS LATER I WAS TALKING TO A FRIEND WHO OWNS A 2010 GMC SUBURBAN AND HE HAD THE EXACT SAME PROBLEM. I SUBSEQUENTLY WENT ON LINE, SEARCHED ON GOOGLE, AND DISCOVERED A NUMBER OF OTHER OWNERS THAT HAD THE SAME PROBLEM WITH THEIR VEHICLES. THIS IS A DESIGN FLAW IN WHICH THE TANK IS DESIGNED WITH THE DEEP CIRCULAR DEPRESSION (A PERFECT SUMP CONDITION) FOR THE MOUNTING OF THE FUEL PUMP AND WITH NORMAL ROAD DRIVING (MOST NOTABLY IN THE NORTHEAST OR NORTHWEST WHERE RAIN AND SNOW IS PREVALENT) THE SUMP WILL STAY MOIST WITH MUD AND DEBRIS COLLECTING CAUSING RUST IN THE FUEL PUMP HOUSING/MOUNTING RING. *TR

EXTERIOR LIGHTING
HEADLIGHTS ARE TOO DIM IN 2014 GMC SIERRA. TO THE POINT OF DANGEROUS TO PEDESTRIANS AND WILDLIFE. THE LIGHTS HINDER THE ABILITY OF DRIVERS TO SEE AND AVOID ANYTHING THAT MAY WONDER INTO THE VEHICLES PATH. BY THE TIME THE HEADLIGHT ILLUMINATE THE OBJECT IT'LL BE TOO LATE! "SAVE SOME LIFE", PERSUADE GENERAL MOTORS TO FIX FUTURE VEHICLES AND POSSIBLY RECALL EXISTING ONES. *TR

I PULLED INTO MY DRIVEWAY AND APPROACHED THE GARAGE, APPLIED BRAKES AND ALL THEY DID WAS VIBRATE AND MAKE THAT PULSE NOISE. NO MATER HOW HARD I PUSHED THE PEDAL, THE TRUCK WOULD NOT STOP AND I WENT THROUGH THE GARAGE DOOR AND ALSO KNOCKED OVER MY HARLEY THAT WAS IN THE GARAGE. I CANT BELIEVE THE AMOUNT OF COMMON STORY'S ABOUT THIS BRAKE ISSUE. THERE SHOULD BE A CLASS ACTION LAWSUIT. *TR

AIR BAGS
IN LATE OCTOBER, 2013, I PURCHASED MY 2006 GMC SIERRA C1500 STANDARD CAB, 2WD PICKUP FROM A PRIVATE OWNER. ON OR ABOUT, DECEMBER 01, 2013, I NOTICED THAT THE "SERVICE AIR BAG" WARNING MESSAGE APPEARED INTERMITTENTLY. THE "AIRBAG" ILLUMINATED SYMBOL IN THE DASH INSTRUMENTATION AREA WAS ALSO ILLUMINATED. THIS WOULD RANDOMLY COME ON AND GO OFF DURING NORMAL OPERATION OF THE VEHICLE. I SUBSEQUENTLY TOOK THE TRUCK TO A LOCAL GMC/CHEVROLET DEALER FOR SERVICE OF THIS PROBLEM. THEY CHARGED ME TO FIX THE ISSUE AND IT DID NOT APPEAR FOR ABOUT A WEEK AFTER THEIR REPAIR. I SHOULD HAVE KNOWN BETTER, AS THE DEALERSHIP HAS BEEN UNABLE TO SUCCESSFULLY REPAIR PREVIOUS ISSUES ON OTHER VEHICLES THAT I HAVE HAD SERVICED THERE. THE "SERVICE AIR BAG" MESSAGE HAS BEEN ON CONSTANTLY SINCE ABOUT FEBRUARY, 2014, AS WELL AS THE ILLUMINATED ICON IN THE INSTRUMENT CLUSTER. I HAVE NO CONFIDENCE IN MY LOCAL DEALERSHIP WITH THEIR ABILITY TO REMEDY THE SITUATION AND MAY HAVE TO SEEK THIRD PARTY REPAIR FOR THIS ISSUE. GENERAL MOTORS SEEMS TO HAVE NO WEB SITE TO ASSIST OWNERS AND I MUST NOW GLEAN KNOWLEDGE FROM THE INTERNET IN AN ATTEMPT TO REMEDY THE ISSUE. I CAN FIND NO RECALL INFORMATION FOR MY MAKE AND YEAR OF VEHICLE FOR THIS PROBLEM, BUT, THAT DOES NOT MEAN THAT ONE DOES NOT EXIST. *TR

SERVICE BRAKES
TRUCK WAS IN SHOP FOR UNRELATED MAINTENANCE. BRAKE LINE FAILURE OCCURRED WHILE MOVING TRUCK OUT OF SERVICE BAY. TRUCK IS CURRENTLY UNDRIVEABLE. MECHANIC INDICATED THAT THIS IS COMMON FAILURE AS LOWER QUALITY MATERIAL WAS USED IN THE BRAKE LINES. ADDITIONAL RESEARCH ON WEB INDICATED THIS IS A WIDESPREAD ISSUE. THIS IS THE FIRST I HAD HEARD OF THE PROBLEM. I AM THE ORIGINAL OWNER. I FEEL BLESSED THAT THIS FAILURE OCCURRED IN A NON-TRAFFIC SITUATION. I FREQUENTLY DRIVE THIS TRUCK IN HEAVY TRAFFIC ON I-94. THANKS,[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
