POWER TRAIN
GM PERFORMED A RECALL FOR FRACTURED TRANSMISSION DIPSTICK TUBE ON MY TRUCK. THEY TOOK A TUBE OF FOAM AND PLASTIC STRAPPED IT TO THE TUBE. I NEVER SAW THE REASONING! THE TUBE HAS FRACTURED AND NOW HAS TO BE REPLACED. WHY DID THE NOT FIX THIS PROPER IN THE FIRST PLACE. NOW I NEED TO MAKE TWO MORE APPOINTMENTS TO GET THIS FIXED. MY TRANSMISSION IS OPEN TO THE ELEMENTS, WATER AND DIRT! *TR

EXTERIOR LIGHTING
2014 GMC SIERRA 1500 Z-71 PROJECTION HEADLIGHTS ARE WITH OUT A DOUBT A SAFETY HAZARD. NOT ONLY ARE THEY DIM BUT THEY DO NOT "PROJECT" FAR ENOUGH DOWN THE ROAD IN EITHER THE LOW OR HIGH BEAM MODES. UNSAFE BECAUSE ONE OVER DRIVES THE BEAM PROJECTED. UNSAFE BECAUSE ONE CANNOT SEE OFF TO THE SIDES WHERE DEER AND OTHER ANIMALS APPROACH SOMETIMES AT HIGH SPEEDS. THERE IS NO DOUBT IN MY MIND THAT GENERAL MOTORS WILL HAVE TO CHANGE OUT THESE HEADLIGHTS EITHER SOONER OR LATER UNDER A RECALL. *TR

SERVICE BRAKES
ON 9-19-2014 THE TRUCK WAS STOPPED AT A RED LIGHT AND STARTED TO INCH FORWARD. SLIGHT PRESSURE ON THE BRAKE PEDAL STOPPED THE MOVEMENT. THE EVENT WAS SO QUICK AND SLIGHT I THOUGHT NOTHING ABOUT IT. I TURNED ON THE FREEWAY AND DROVE 30 OR 40 MILES BEFORE TOUCHING THE BRAKE PEDAL AGAIN. WHEN I DID IT WENT ALMOST TO THE FLOOR WITHOUT SLOWING THE TRUCK SPEED ANY APPRECIABLE AMOUNT. AT THAT POINT I KNEW I HAD A SERIOUS PROBLEM. I GEARED THE TRUCK DOWN AND WAS ABLE TO AVOID BEING INVOLVED IN AN ACCIDENT. IF I HAD NEEDED TO COME TO A FULL AND FAST STOP IT COULD EASILY HAVE BEEN A DISASTER. AN INTERNET SEARCH REVEALED GM HAS HAD THIS PROBLEM FOR SOME TIME WITHOUT NOTICE TO TRUCK OWNERS THAT IT EXISTS. AN INSPECTION OF THE BRAKE LINES WAS DONE AND INDICATED A FAILURE IN THE BRAKE LINE SYSTEM DUE TO RUST. THE FUEL LINES SHOWED THE SAME KIND OF DETERIORATION. PICTURES CAN BE PROVIDED TO VERIFY THE LACK OF ADVANCED RUST CONDITIONS TO THE UNDERNEATH OF THE TRUCK OTHER THAN THE BRAKE LINE SYSTEM, THE FUEL LINE SYSTEM, AND THE DRIVE SHAFT. THE TRUCK WAS PURCHASED NEW IN SOUTH CAROLINA AND HAS BEEN DRIVEN THERE 90% ON THE TOTAL MILEAGE ON IT. *TR

SERVICE BRAKES
MY 16 YEAR OLD DAUGHTER WAS DRIVING THE TRUCK AT THE TIME OF THE FAILURE. SHE HAS HER TEMPORARY LICENSE AND WAS DRIVING FOR THE THIRD TIME. AFTER DRIVING IN TOWN AND ON SOME RURAL ROADS, SHE STARTED GETTING TOO CLOSE TO OTHER CARS AT STOP LIGHTS AND STOP SIGNS. I BEGAN TELLING HER TO STOP SOONER, SHE SAID SHE WAS TRYING. IT ONLY GOT WORSE SO WE WENT HOME. SHE ALMOST RAN INTO OUR HOUSE AS TRIED TO STOP IN THE DRIVEWAY. BECAUSE SHE IS A NEW DRIVER, SHE DID NOT REALIZE THE BRAKES WERE GOING OUT. AFTER WE GOT OUT OF THE TRUCK I NOTICED A PUDDLE OF FLUID FORMING UNDER THE DRIVER SIDE. I DETERMINED THAT IT WAS BRAKE FLUID. I RAISED THE HOOD AND HAD HER PRESS ON THE BRAKE PEDAL. BRAKE FLUID STARTED SPRAYING OUT OF A BRAKE LINE NEAR THE FRAME. THE BRAKE LINES FROM THE MASTER CYLINDER TO THE ABS MODULE ARE VERY RUSTY ALONG WITH EVERY OTHER BRAKE LINE. THIS TRUCK MAY BE 12 YEARS OLD AND HAVE 87,000 MILES BUT I HAVE ALWAYS TAKEN VERY GOOD CARE OF IT AND IT STILL LOOKS NEW INSIDE AND OUT. I DO NOT BELIEVE A MAJOR SAFETY COMPONENT LIKE THE BRAKES SHOULD BE FAILING AT THIS TIME. OTHER CRITICAL COMPONENTS HAVE WARNING SYSTEMS TO ALERT YOU TO POSSIBLE FAILURES BUT WHEN THERE IS NO WAY TO TELL IF SOMETHING CRITICAL WILL FAIL I BELIEVE THOSE PARTS SHOULD BE MADE TO LAST. IF THE LIFE EXPECTANCY OF A PART IS LIMITED, THE MANUFACTURER SHOULD RECOMMEND SERVICE AT A REASONABLE INTERVAL. MY DAUGHTER IS NOW SCARED TO DEATH TO DRIVE ANY OF OUR CARS BECAUSE SHE FEELS IT COULD HAPPEN AGAIN. I AM JUST GLAD I WASN'T PULLING MY 20 FOOT BOAT AND HAD TO MAKE A PANIC STOP AT HIGHWAY SPEEDS WHEN THE LINE FAILED. SOMEONE COULD HAVE GOT INJURED OR KILLED I AM CURRENTLY GETTING QUOTES TO HAVE IT REPAIRED. SO FAR I HAVE RECEIVED PRICES RANGING FROM $600-1500. I FEEL GM SHOULD COVER MOST TO ALL OF THESE EXPENSES BECAUSE THEY USED SUB-PAR PARTS TO BUILD A CRITICAL COMPONENT OF THE BRAKE SYSTEM. *TR

STRUCTURE:BODY, LATCHES/LOCKS/LINKAGES
AT 35K THE DRIVERS SIDE FRONT DOOR ACTUATOR FAILED AND WAS REPLACED UNDER WARRANTY. AT 40K THE PASSENGER SIDE DOOR ACTUATOR FAILED. I WAS TOLD THIS IS A COMMON PROBLEM WITH THIS VEHICLE DUE TO DEFECTIVE PARTS USED BY GMC. WITH NO ABILITY TO OPEN OR CLOSE THE PASSENGER DOOR FROM THE DRIVERS CONTROL, A POTENTIAL SAFETY ISSUE EXISTS. E.G. UNABLE TO PREVENT AN INTRUDER FROM ENTERING THE CAR AT A STOP LIGHT, OR ALLOW A SCARED CHILD TO EXIT AFTER AN ACCIDENT. *TR

SERVICE BRAKES
THIS SELDOM USED, WELL MAINTAINED, GARAGED TRUCK, BLEW OUT THE BRAKE LINES ON LEFT SIDE ON THE FRAME, UNDER THE DOOR, RESULTING IN TOTAL BRAKE FAILURE. I HAD TO USE THE PARKING BRAKE TO STOP THE VEHICLE. I WAS ON MY WAY TO PICK UP A #9000 BOAT. IF I HAD THAT BOAT BEHIND THE TRUCK, IT COULD HAVE KILLED ME, OR OTHERS ON THE ROAD. BRAKE LINES ARE NOT A NORMAL SERVICE PART. REPLACING ALL THE BRAKE LINES IS COSTING ME 1300, AT A MINIMUM. MY NEIGHBOR NEXT DOOR HAS A SIMILAR 2004 GMC SIERRA, WITH ABOUT THE SAME MILEAGE, ONLY HIS IS A 1/2 TON, WHERE MINE IS 3/4 TON. HIS TRUCK HAD THE SAME FAILURE THE WEEK BEFORE, IN THE EXACT SAME LOCATION ON THE LINES. DO A SIMPLE SEARCH LOOKING FOR BRAKE FAILURES ON THESE VEHICLES, AND YOU FIND THAT ITS WELL DOCUMENTED. THIS SHOULD BE A RECALL BEFORE PEOPLE ARE KILLED. THERE IS NO WAY THAT I SHOULD BE LOOKING AT BRAKE LINE FAILURE ON A 10 YEAR OLD GARAGED TRUCK THAT HAS A TOW CAPACITY OF OVER 10,000 #'S. HOW SHOULD SOMEONE DETECT THE INTEGRITY OF THE BRAKE LINES TO DETERMINE WHEN THE SHOULD BE REPLACED? *TR

SERVICE BRAKES
I WENT OUT TO MY TRUCK IN THE MORNING AND MY DASH BOARD INDICATOR TOLD ME TO GET MY BRAKES CHECKED; EVERYTHING WAS FINE THE NIGHT BEFORE. I BROUGHT THE TRUCK INTO MYMECHANIC AND FOUND OUT THAT MY BRAKE LINE IS CORRODED AND BROKEN. ALSO FOUND OUT THAT THIS A RECURRING AND CONSISTENT PROBLEM WITH THE GMC SIERRAS. I HAVE MY TRUCK SERVICED BY AN AUTHORIZED SERVICE CENTER ON A REGULAR BASIS AND THIS HAS NEVER BEEN MENTIONED TO ME. THIS NEEDS TO BE A RECALL ITEM! SERIOUS SAFETY THREAT. CANNOT IMAGINE WHAT COULD HAVE HAPPENED IF THIS OCCURRED 2 DAYS LATER WHEN I WAS PULLING OUR 40 FOOT RV. SHOULDN'T GM BE RESPONSIBLE FOR THIS? MY TRUCK IS NOW IN THE SHOP GETTING THE BRAKE LINE REPLACED. *TR

POWER TRAIN
INITIALLY I FELT THE PROBLEM AS A SLIGHT "MISSING" IN THE ENGINE UNDER VERY LIGHT ACCELERATION BETWEEN 40 MPH AND 55MPH AND MORE PRONOUNCED UNDER CONSTANT THROTTLE GOING UP GRADES ON THE HIGHWAY AT A SPEED OF ~55 MPH (1400-1500 RPM). THE VEHICLE SEEMED TO BE "LUGGING", AND THEN THE RPM WOULD INCREASE BY ~20% IMMEDIATELY FOR A SHORT DISTANCE AND THEN DROP BACK (ALL AT CONSTANT THROTTLE) TO 1400-1500 RPM. WHEN DRIVING ON THE HIGHWAY IN CRUISE CONTROL AT 60 MPH AND GOING UP A GRADE, THE VEHICLE WOULD SHOW SIGNS OF "STRAINING" AND IMMEDIATELY INCREASE IN THE RPM BY ABOUT 20% WITH AN ATTENDANT ACCELERATION. THEN THE RPM WOULD INCREASE INSTANTLY BY ABOUT 1000 RPM AND THE VEHICLE ACCELERATES RAPIDLY UNTIL I ENGAGE THE BRAKES. MY DEALER OBSERVED THE SAME CHARACTERISTICS AND DETERMINED THAT IT WAS A TORQUE CONVERTER PROBLEM AND ON 07/25/2014 THEY INSTALLED A NEW TORQUE CONVERTER, WHICH PROVED TO HAVE NO EFFECT ON THE PROBLEM. I WAS INFORMED BY THE SERVICE MANAGER THAT GMC TECHNICAL SERVICES INFORMED HIM OF A SERVICE BULLETIN (#PIP4681D: RANDOM BUMP CHUGGLE OR FISHBITE SENSATION WHILE CRUISING AT APPROXIMATELY 1,300 RPM- OCTOBER 31, 2013) THAT ADDRESSED THE PROBLEM, AND FURTHERMORE NO FURTHER CORRECTIVE ACTION COULD BE TAKEN. ON AUGUST 6,,2014 I WAS DRIVING AT CONSTANT SPEED OF 60 MPH ON A MAJOR HIGHWAY IN "CRUISE CONTROL" AND MODERATE TRAFFIC. WHILE GOING UP A LONG GRADE FOLLOWING ANOTHER VEHICLE AT A SAFE SPEED, MY VEHICLE IMMEDIATELY JUMPED ~400 RPM AND THEN ABRUPTLY CHANGED TO A LOWER GEAR AND ACCELERATED SUDDENLY PUTTING ME AT RISK OF COLLIDING WITH THE VEHICLE AHEAD OF ME. I QUICKLY APPLIED BRAKES AND WAS ABLE TO AVOID AN ACCIDENT. I IMMEDIATELY CONTACTED GMC CUSTOMER SERVICES WHO OPENED A CASE NUMBER ([XXX]) AND ASSIGNED A REP. TO MY CASE. I HAVE SUBSEQUENTLY BEEN INFORMED OF THE GMC COMPANY LINE--"THE VEHICLE IS OPERATING AS DESIGNED", "LIVE WITH IT"!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE HEATING AND AC CONTROLS WERE REPLACED 2 TIMES IN 2007.AND ARE STILL NOT WORKING PROPERLY TODAY I WAS DRIVING HOME WITH THE AC ON BECAUSE IT'S 99 DEGREES IN LOS ANGELES COUNTY AND LIKE IT HAS BEEN DOING FOR YEARS IT STARTED BLOWING HOT AIR ON ITS OWN. I HAVE SEE OTHER GM VEHICLES WITH THE SAME ISSUE. SO I BELIEVE GM IS RESPONSIBLE FOR CORRECTING THIS ISSUE. *TR

POWER TRAIN, VEHICLE SPEED CONTROL
TRAVELING AT A LOW SPEED ON MY PROPERTY AND THE TRUCK ENTERED INTO A "REDUCED POWER" MODE. WHICH CUT OFF ALL POWER TO THE DRIVE TRAIN. YOU WERE LEFT WITH NO ABILITY TO GO FRONT OR BACK. AFTER SHUTTING OFF THE TRUCK AND RESTARTING IT RETURNED TO NORMAL. LOCAL GMC DEALER SAYS HE GETS ONE A MONTH FOR THIS CONDITION. COSTS TO REPAIR EXCEEDS A $1000. LOST OF POWER COULD HAPPEN ANY TIME. VERY DANGEROUS SITUATION. *TR
