ELECTRICAL SYSTEM
FIRST THE FUEL GAUGE WAS ERRATIC THEN FAILED, THEN THE SPEEDOMETER PEGGED AND IS FAILING TO SHOW EVEN CLOSE TO TRUE SPEED AS IN SHOWING 100+MPH IN AN ACTUAL +/-35MPH RANGE. CIRCUMSTANCES MATCH DESCRIPTION OF COMMON PROBLEMS WITH INSTRUMENT CLUSTER FAILURES ON THAT MAKE AND MODEL. *TR

ENGINE
TRUCK IS LEAKING OIL, AND I HAVE A SMALL PUDDLE OH GARAGE FLOOR. BROUGHT TO ORIGINAL SELLING DEALER TO BE CHECKED. THEY CLAIMED THERE WAS A PLUG ON BACK OF ENGINE THAT WAS LEAKING. THEY HAD VEHICLE FOR 3 1/2 DAYS, AND CLAIMED IT WAS FIXED. THEY HAD OVER 1 PAGE OF SEALS, GASKETS, PLUG WERE REPLACED. DROVE APPROXIMATELY 50 MILES, AND IT STARTED LEAKING EXACTLY THE SAME AS BEFORE. RETURNED TO DEALER AGAIN, AND WAS TOLD BY THE SERVICE TECHNICIAN THAT IT WAS NORMAL TO SEE IT HAVING A LEAK DUE TO THE SILICONE THAT WAS USED ON ENGINE PARTS WHEN IT WAS BUILT !!! I WAS ADVISED TO DRIVE IT FOR 1 WEEK AND BRING IT BACK AGAIN. AT THAT POINT IN TIME, I CONTACTED GM AND WAS TOLD TO GET A SECOND OPINION AT ANOTHER DEALERSHIP. I BROUGHT IT TO THEM ON 11/15/13. IT HAS BEEN THERE NOW FOR 6 DAYS. I WAS JUST TOLD THAT THEY HAVE 4 PAGES OF NEW PARTS THAT HAVE TO BE ORDERED TO REPAIR IT. THEY (DEALERSHIP) REQUESTED THAT GM REPLACE THE ENGINE AND WAS DENIED. CONSIDERING THIS IS THE 3RD TIME TRYING TO REPAIR THE SAME PROBLEM, THEY SHOULD EITHER RE-PURCHASE OR LEMON LAW THIS. *TR

SERVICE BRAKES
WHILE DRIVING THE TRUCK ON A RESIDENTIAL STREET, THE BRAKES COMPLETELY FAILED WHEN I DEPRESSED THE BRAKE PEDAL (IT WENT TO THE FLOOR) AND ATTEMPTED TO STOP. I LOST ALL NORMAL BRAKING ABILITY AND HAD TO STOP BY DOWN SHIFTING AND APPLYING THE EMERGENCY BRAKES. WHEN I GOT THE TRUCK STOPPED AND GOT OUT, I FOUND THAT THE BRAKE FLUID WAS POURING OUT ONTO THE GROUND. A QUALIFIED MECHANIC INSPECTED THE TRUCK AND FOUND THAT THE BRAKE LINES WERE RUSTED THROUGH AND HAD RUPTURED. HE WENT ON TO TELL ME THAT THIS PROBLEM IS A FREQUENTLY OCCURRING KNOW PROBLEM WITH GMC PICKUP TRUCKS AND THAT GMC REFUSES TO ACKNOWLEDGE THE ISSUE. *TR

SERVICE BRAKES
WHEN TRAVELING THROUGH AN INTERSECTION AT A GREEN LIGHT ANOTHER VEHICLE ILLEGALLY ENTERED THE INTERSECTION. I SAW THE VEHICLE AND ATTEMPTED TO STOP BUT WHEN I HIT THE BRAKES THE PEDAL WENT DOWN TO THE FLOOR AND NO BRAKING ACTION OCCURRED. I WAS TOLD I BLEW A BRAKE LINE. THE CAR WAS REPAIRED OF THE DAMAGE FROM THE ACCIDENT BUT I HAD TO PAY FOR THE BRAKE LINE REPAIR. AFTER GETTING THE TRUCK BACK I BROUGHT IT BACK TO THE REPAIR SHOP FOR AN ALIGNMENT WITHIN A FEW DAYS. WHILE THE REPAIR SHOP WAS DRIVING THE CAR IN FOR THE ALIGNMENT A SECOND BRAKE LINE BLEW. THERE IS NOT A RECALL FROM GMC AND THERE NO REASON WHY THE BRAKES LINES SHOULD BE RUSTING OUT AND BLOWING ON A CAR THAT IS WELL MAINTAINED. *TR

SERVICE BRAKES
WHILE TRYING TO PARK MY VEHICLE IN A PARKING LOT THE BRAKES ANTI-LOCK SYSTEM ENGAGED. I WAS PULLING FORWARD TO BACK INTO A STALL. THERE WAS A PERSON WALKING DOWN THE PARKING LOT SOME DISTANCE IN FRONT OF ME. AS I APPLIED THE BRAKES TO STOP GOING FORWARD AND START TO BACK THE ABS SYSTEM ENGAGED AND I COULD NOT STOP. THE GENTLEMAN IN FRONT OF ME THOUGHT I WAS GOING TO HIT HIM, AND QUITE FRANKLY I THOUGHT THAT I WAS ALSO. THE PAVEMENT WAS DRY, THE TEMPERATURE WAS ABOUT 62 DEGREES. THIS IS A DANGEROUS SITUATION. THERE IS NOTHING WRONG WITH MY BRAKES AT HIGHER SPEEDS. I HAVE READ SOME THINGS ABOUT ISSUES WITH THE ABS SPEED SENSORS ON THE WHEELS. IF THIS IS THE CASE GM NEEDS TO RECALL ALL OF THESE VEHICLES BEFORE THERE ARE SERIOUS ACCIDENTS OR DEATHS!! *TR

SERVICE BRAKES
AFTER STARTING THE TRUCK, I STEPPED ON THE BRAKE PEDAL TO SHIFT OUT OF PARK. UPON PRESSING THE BRAKE PEDAL, MY FOOT WENT TO THE FLOOR AND A LOUD POP/SNAP NOISE WAS HEARD. THE REAR STEEL BRAKE LINE HAD CORRODED AND BURST. AFTER BEING TOWED TO THE MECHANIC AND BEING INSPECTED, I WAS TOLD THAT ALL STEEL BRAKE LINES WERE CORRODED AND HAD TO BE REPLACED. THE MECHANIC ALSO NOTED THE EXTREMELY HIGH FAILURE RATE OF THE BRAKE LINES IN FULL SIZE GM VEHICLES FROM THAT TIME PERIOD. THIS IS THE SECOND GM TRUCK I HAVE OWNED THAT A BRAKE LINE FAILURE HAS OCCURRED; EXPERIENCING THE SAME FAILURE WITH MY 1992 CHEVROLET SILVERADO. *TR

FUEL SYSTEM, GASOLINE
THE GAS GAUGE IS NOT DEPENDABLE. SOMETIMES ACCURATE, BUT MORE OFTEN, NOT ACCURATE. IT IS A CONTINUOUS PROBLEM. YOU MAY RUN OUT OF GAS AT ANY MOMENT, IN TRAFFIC, ON THE INTERSTATE AT HIGH SPEEDS, THEN YOU HAVE NO STEERING OR BRAKES, ENGINE IS DEAD. IT HAS HAPPENED MANY TIMES, ONCE WHEN IT SHOWED 3/4 TANK FULL. I HAVE A 2001 CHEVY REGULAR CAB PICKUP TRUCK THAT DOES THE SAME THING. I HAVE TALKED TO MANY OTHER OWNERS THAT HAVE THE SAME PROBLEM. IT IS DEFINITELY A FACTORY DEFECT. *TR

SERVICE BRAKES
I BOUGHT A 2006 SIERRA DENALI WITH 65000 MILES ON THE TRUCK IN MAY OF 2013. I LOST MY BRAKES AND ALMOST REARENDED A MAN PULLING INTO HIS DRIVEWAY. I ALSO HAD MY 3 KIDS AND MY FIANCE IN THE TRUCK WITH ME. I TOOK MY TRUCK TO ROBERTSONS GMC IN WAREHAM,MA AND THEY TOLD ME MY BRAKE LINES WERE COMPLETELY ROTTED AS WELL AS MY FRAME. I ALSO HAD A EXTENDED WARRANTY WHICH DID NOT COVER IT BECAUSE IT WAS A PRE-EXISTING PROBLEM. I JUST DON'T UNDERSTAND HOW GM CAN GET AWAY WITH ALL OF THESE FRAME CORROSION AND BRAKE LINE CORROSION PROBLEMS WITHOUT HAVING TO FIX THE PROBLEMS WITH THERE TRUCKS. I HAVE RESEARCHED ALOT ON THESE PROBLEMS AND IT SEEMS LIKE NO ONE IS HOLDING GM RESPONSIBLE AND MAKING THEM FIX THE CORROSION PROBLEM.I THINK THEY SHOULD HAVE TO FIX THE PROBLEM LIKE TOYOTA DID WHEN THEY HAD FRAME PROBLEMS SO THAT THEY CAN STOP PRODUCING VEHICLES THAT DONT LAST 10 YEARS WITHOUT ROTTING AWAY. *TR

SEATS
I HAVE A 2014 GMC SIERRA SLT WITH POWER SEATS. THE DRIVER'S SEAT IS LOOSE (NOT THE SAME ISSUE THAT WAS RECENTLY RECALLED WITH MANUALLY RECLINING SEATS). WHEN YOU MAKE A SHARP TURN AT SPEED THE DRIVERS SEAT SLIDES LEFT OR RIGHT DEPENDING ON THE DIRECTION YOU ARE TURNING. THERE ARE NUMEROUS COMPLAINTS IDENTICAL TO THIS ONE ON THE FORUMS ONLINE AND GM CLAIMS THEY HAVE NO SOLUTION AND TO SPEAK WITH THE LOCAL DEALER. MY LOCAL DEALER DOES NOT NOW KNOW WHAT TO DO AND SAYS THEY CANNOT FIX IT. THIS IS A VERY DANGEROUS SITUATION AND COULD CAUSE AN ACCIDENT! PLEASE HAVE GM FIX IT OR ISSUE A RECALL! *TR

SERVICE BRAKES
I HAVE A 2002 GMC SIERRA AND JUST PULLED OUT OF MY DRIVEWAY GOING DOWN THE STREET TO STOP SIGN AND BRAKE PEDDLE WENT ALL THE WAY TO THE FLOOR CAUSING ME TO GO THRU STOP SIGN. LUCKY NO ONE WAS GOING THE OTHER WAY! MANAGED TO MAKE IT BACK HOME AND NOTICED DRIVEWAY ALL WET .LOOKED UNDER TRUCK AND NOTICED THE BREAK LINES ALL ROTTED! I CANT BELIEVE THAT GENERAL MOTORS WOULD MAKE STEEL BRAKE LINES KNOWING THAT STEEL WILL ROT !DID THEY JUST FIGURE THAT OUT? I THOUGHT THEY SHOULD KNOW BETTER!!!! WHY DON'T I HERE ABOUT OTHER VEHICLE MAKES DON'T HAVE THIS PROBLEM. DID THEY JUST LEARN ABOUT STEEL? THIS IS AND IMPORTANT SAFETY ITEM AND BREAKS NEED TO WORK ALL THE TIME. I ALSO NOTICED THE MY FUEL LINES ARE SHOWING THE SAME SIGNS. GM SHOULD REPAIR AND LEARN FROM THIS BAD CHOICE TO INSTALL INFERIOR EQUIPMENT FOR SUCH AN IMPORTANT SYSTEM IN ANY VEHICLE. I HAVE SINCE REPAIRED MY BREAK LINES AT A VERY EXPENSIVE $1,500 ! *TR

STRUCTURE:BODY, POWER TRAIN
AT THIS OCCURRENCE THE HOOD LATCH DOES NOT KEEP THE HOOD TIGHT WHEN CLOSED. THE HOOD RATTLES AT SPEEDS OVER 35MPH AND APPEARS AS THOUGH IT IS GOING TO OPEN. AS A RESULT OF ATTEMPTING TO SUFFICIENTLY SECURING THE HOOD, I SUBSEQUENTLY DENTED THE HOOD. I HAVE HAD THE BODY DEPARTMENT AT THE LOCAL DEALERSHIP LOOK AT IT AND THEY FOUND THAT THE HOOD LATCH NEEDED TO BE ADJUSTED. AFTER ANOTHER 2500 MILES, THIS RATTLE HAS RETURNED. THE COMPLAINT IS THAT THIS IS THE SECOND 2013 SIERRA DENALI THAT I HAVE OWNED SINCE OCTOBER 2012, SINCE THE DEALERSHIP BOUGHT BACK THE FIRST ONE AFTER NUMEROUS PROBLEMS INCLUDING THE TRANSMISSION BEING REPLACED AT 6250 MILES AND NUMEROUS EFFORTS TO FIX THE HOOD. SAME PROBLEM TWO TRUCKS IS A CAUSE FOR CONCERN! *TR
