• 12/26/2013· SERVICE BRAKES

  I WAS I 91 SOUTH HEADING IN TO HARTFORD CT, TRAFFIC WAS HEAVY AND AS A RESULT I WAS TRAVELING APPX 20 MPH AS I ENTERED THE RAMP EXIT LANE. I STEPPED ON BRAKE PEDAL AND THE PEDAL WENT TO THE FLOOR, FORTUNATELY I WAS ABLE TO VEER INTO THE BREAKDOWN LANE AND AVOID HITTING OTHER CARS. I SLOWLY MADE IT TO MY PLACE OF EMPLOYMENT AND LATER HAD THE TRUCK TOWED HOME. AS IT TURNS OUT I DISCOVERED THE ALL BRAKE LINES HAD CORRODED AND HAD TO BE REPLACED. I CONTACTED GM AS I THOUGHT IT VERY UNUSUAL FOR ALL BRAKES LINES TO BE SO SEVERELY CORRODED. THEY ATTRIBUTED THE SEVERE CORROSION TO THE FACT THAT THE TRUCK WAS 10 YEARS OLD AND REFUSED TO COVER THE EXPENSE AND CONSIDERED THE CASE CLOSED. BY DOING A SIMPLE INTERNET SEARCH I FOUND THAT THIS SAME PROBLEM IS QUITE COMMON AND MY MECHANIC ALSO INFORMED THAT GM ( POSSIBLY AS A RESULT OF THIS BEING A COMMON ISSUE) HAS MADE A AVAILABLE A BRAKE LINE REPLACEMENT KIT. *TR

• 12/20/2006· EXTERIOR LIGHTING

  MY 2004 GMC SIERRA WOULD LIGHT ALL FOUR TURN SIGNALS WHEN THE LEFT TURN SIGNAL WAS APPLIED, AS IF THE HAZARD LIGHTS WERE ON. TOOK IT TO DEALER AND THEY SAID THEY HAD NEVER SEEN ANYTHING LIKE IT BEFORE. PAID ALMOST 200 DOLLARS TO GET IT LOOKED AT AND FIXED. AFTER GOING HOME, I SEE THAT OTHER SIERRA USERS HAVE THE SAME PROBLEM. MORE SHOCKING, I SEE THAT GM HAD THE EXACT SAME PROBLEMS WITH SOME ENVOYS, BARBADOS, TRAILBLAZERS, AND OTHERS, AND PERFORMED A SAFETY RECALL AT NO CHARGE. IT IS OUTRAGEOUS THAT ALL VEHICLE OWNERS WITH THESE PROBLEMS WERE NOT NOTIFIED AND THE FAULTY COMPONENTS REPLACED. HAVE BEEN TRYING TO GET IN TOUCH WITH GM ABOUT THIS AND THEY HAVE YET TO SEND ME ANYTHING BUT CARBON-COPY E-MAILS AND RUNAROUNDS. *JB

  #1 04 SIERRA 4X4 RETURNED TO DEALER AFTER 2 WEEKS (9/18/04) WITH 1523 MILES FOR HARD SHIFTING. CLUTCH WAS NOT INSTALLED CORRECTLY FROM FACTORY. ENGAGE AND DISENGAGE POINT IN CLUTCH PEDAL TRAVEL IS AT FULL DEPRESSION INTO THE FIREWALL. #2 PASSENGER DOOR HARD TO CLOSE FULLY. DRIVER SIDE DOOR CLOSES AS EXPECTED WITH LITTLE EFFORT. PASSENGER DOOR WILL NOT CLOSE COMPLETELY WITHOUT UNDUE FORCE BEING APPLIED OR A WINDOW CRACKED. #3 RETURNED TRUCK TO A DIFFERENT DEALERSHIP ON 9/15/05 WITH 8,190 AND AGAIN 12/15/05 WITH 10,282 MILES. FOR A KNOCKING NOISE DURING TURNING, CLUTCH NOT ENGAGING AND DISENGAGING CORRECTLY, PASSENGER DOOR NOT CLOSING COMPLETELY, AND A NEW RATTLING NOISE FROM THE TRANSMISSION ALONG WITH A WHINE NOISE FROM THE GEARS. THE DEALERSHIP FIXED THE KNOCKING NOISE FROM A SERVICE BULLETIN CONCERNING A STEERING BUSHING. THIS DEALERSHIP ALSO STATED THEY FOUND NOTHING WRONG WITH THE CLUTCH OR THE TRANSMISSION OR THE PASSENGER DOOR. NONE OF THE PROBLEMS WERE FIXED #5 I IMMEDIATELY TOOK THE TRUCK TO AN INDEPENDENT TRANSMISSION SPECIALIST AFTER PICKING IT UP FROM THE DEALERSHIP FOR A 3RD OPINION ON 12/20/05 WITH 10,284 MILES. HIS OPINION WAS FLATLY STATED THAT THE TRUCK HAS MAJOR PROBLEMS WITH THE CLUTCH AND THE TRANSMISSION. HIS EVALUATION WAS THE CLUTCH WAS NOT INSTALLED CORRECTLY FROM THE FACTORY AND DEPRESSION INTO THE FIREWALL WAS NOT CORRECT. THE TRANSMISSION HAS SYNCHRONIZER AND POSSIBLE BUSHINGS AND BEARINGS THAT WERE FAILING. HE STATED THE NOISES ALONE WERE DEFINITE INDICATORS THAT THE TRANSMISSION HAS PROBLEMS AND THAT ANYONE WOULD KNOW THAT A CLUTCH IS NOT REQUIRED TO BE DEPRESSED INTO THE FIREWALL FOR PROPER OPERATION WHICH IN TIME WILL LEAD TO PREMATURE CLUTCH FAILURE. THIS EVALUATION COST ME $30 AND 3 HOUR LOST FROM WORK. *JB

  I EXPERIENCE BRAKE PEDAL PULSATION (LOW SPEED ABS ACTIVATION) WHEN ROLLING TO A STOP. MY GMC ONSTAR REPORT SAYS THERE IS NOTHING WRONG WITH MY ABS BRAKING SYSTEM YET I HAVE THIS PROBLEM. THE PROBLEM SEEMS TO BE RUSTED AND/OR FROZE UP WHEEL SPEED SENSORS AS VERIFIED BY TWO DIFFERENT MECHANICS. I UNDERSTAND THEY WERE RECALLS BY GMC OF OTHER TRUCKS EXPERIENCING THIS SAME PROBLEM. I REALLY HATE TO PAY $750 FOR NEW FRONT WHEEL BEARING ASSEMBLIES. I WANT MY TRUCK RECALLED FOR THIS PROBLEM. THERE IS A GMC TECHNICAL BULLETIN 03-05-25-007D. I AM NOT SURE THE ABS WILL FUNCTION PROPERLY WHEN REALLY NEEDED?? *TR

  STEERING LINKAGE PROBLEMS: I'VE HAD THE SAME PROBLEM SINCE I'VE OWNED MY TRUCK. MY FATHER, WHO ALSO HAS A 2500HD, HAS THE SAME PROBLEMS AS WELL. THEY LUBED AND GREASED THE SHAFT AT ONE POINT UNDER WARRANTY, BUT THE PROBLEM HAS RETURNED AND IS PERSISTENT IN BOTH OF OUR TRUCKS. BOTH OF OUR TRUCKS ARE '04 MODELS AND I HAVE LESS THAN 40K MILES ON MINE. IT FEELS LIKE THE STEERING WHEEL WILL COME UNATTACHED FROM THE LINKAGE. NOT A VERY SAFE PROBLEM TO HAVE. I HOPE SOMEONE WILL TAKE THESE COMPLAINTS SERIOUSLY. *JB

• 12/14/2006· ELECTRICAL SYSTEM

  SPEEDOMETER FAILS TO RESET TO ZERO. WHEN VEHICLE COMES TO A STOP, THE SPEEDOMETER INDICATOR STOPS AT A SPEED ABOVE ZERO (I.E., 30, 40, 50 MPH). WHEN THE VEHICLE RESUMES TRAVELING, THE SPEEDOMETER INDICATOR STARTS INCREMENTING AT THE SPEED AT WHICH IT STOPPED (I.E., 30, 40, 50 MPH). THEREFORE, THE INDICATED SPEED IS MUCH HIGHER THAN THE ACTUAL SPEED. THIS IS NOT ONE INCIDENT, BUT AN ONGOING CONTINUOUS PROBLEM, AND VERY DANGEROUS. *NM

• 12/13/2012· SERVICE BRAKES

  I WAS APPROACHING A ONE LANE COVERED BRIDGE ON THE WAY HOME FROM WORK AND ANOTHER APPROACHING VEHICLE FAILED TO YIELD. I MADE AN EMERGENCY STOP BY PRESSING FIRMLY ON THE BRAKES. BRAKE PEDAL WENT RIGHT TO THE FLOOR. I HAD TO QUICKLY USE MY FOOT OPERATED EMERGENCY/PARKING BRAKE TO STOP FROM HAVING A HEAD ON COLLISION. I HAD TO PAY CLOSE TO $1200 TO HAVE THE ENTIRE BRAKE LINE SYSTEM REPLACED DUE TO SEVERE RUST OF THE BRAKE LINES. I AM VERY FORTUNATE THAT THIS TURNED OUT THE WAY IT DID. MY LIFE AND THE LIVES OF OTHERS ARE BEING ENDANGERED BY GM NOT USING A MATERIAL THAT IS RESISTANT TO CORROSION. *TR
