2005 GMC SIERRA 1500 Complaints

WHILE DRIVING AT APPROXIMATELY 55 MPH ON URBAN ROAD I HAD TO SLAM ON MY BRAKES BECAUSE OF A DRIVER BACKING OUT OF A DRIVEWAY IN FRONT OF ME. BRAKES INITIALLY SLOWED VEHICLE THEN BRAKE PEDAL WENT CLEAR TO THE FLOOR. I QUICKLY ENGAGED PARKING/EMERGENCY BRAKE AND WAS ABLE TO STOP JUST IN TIME WHILE SIMULTANEOUSLY RUNNING OFF THE RIGHT SIDE OF THE ROAD. AFTER INSPECTION LEAKING BRAKE FLUID WAS OBSERVED ON LEFT UPPER FRAME RAIL JUST TO THE REAR OF THE RADIATOR. AFTER BEING TOWED HOME FUTURE INSPECTION REVEALED A LONGITUDINAL FRACTURE ON THE BRAKE LINE FOR THE RIGHT FRONT WHEEL. NO INJURIES, MINOR DAMAGE TO RIGHT SIDE (BRUSH SCRAPES). *TR

TL* THE CONTACT OWNS A 2005 GMC SIERRA 1500. WHILE OPERATING THE VEHICLE AND DEPRESSING THE BRAKE PEDAL, THE BRAKING SYSTEM MALFUNCTIONED AND THE STOPPING DISTANCE WAS EXTENDED. THE CONTACT DISCOVERED THAT THE BRAKE FLUID LEAKED FROM THE VEHICLE DUE TO RUSTED BRAKE LINES. THE VEHICLE WAS TAKEN TO THE DEALER WHO REPLACED THE BRAKE LINES, BUT THE FAILURE RECURRED. THE CONTACT INDICATED THAT THE FAILURE OCCURRED ON THREE SEPARATE OCCASIONS. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS 42,000.

CASTECH CYLINDER HEADS ON 2001 THROUGH 2006 5.3L VORTEC ENGINES ARE POROUS AND ALLOW ANTIFREEZE TO SEAP INTO THE OIL. THIS IS A SAFETY CONCERN AS IT CAN DESTROY THE ENGINE (OIL DOESN'T LUBRICATE CORRECTLY, SLUDGE BUILDUP) AND LEAVE SOMEONE, AT THE LEAST, STRANDED, AT THE WORST, IT CAN CAUSE A HUGE ENGINE FIRE. GM HAS BEEN AWARE OF THIS SINCE 2007. THEY ISSUED A BULLETIN DESCRIBING THE PROBLEM AND WHAT NEEDS TO BE DONE TO FIX, BUT NO RECALL. TO FIX EITHER THE CYLINDER HEADS NEED TO BE REPLACED ($2500) OR THE ENTIRE ENGINE NEEDS TO BE REPLACED ($5500). MY VEHICLE IS A 2005 GMC SIERRA 1500 SLE. ALSO THE PROBLEM HAS BEEN CONFIRMED BY A LICENSED MECHANIC. THE FOLLOWING IS A LINK TO THE GM ISSUED BULLETIN. HTTP://WW2.JUSTANSWER.COM/UPLOADS/BLUEGORILLA/2008-12-05_142924_COOLANT_LOSS_5.3.PDF

WHEN BACKING OUT OF A LONG DRIVEWAY, THE BRAKE PEDAL SUDDENLY DROPPED TO THE FLOOR AND BRAKES DID NOT SLOW, STOP OR ENGAGE AT ALL. I PUMPED THE BRAKE SEVERAL TIMES WITH NO RESPONSE WHATSOEVER AND WAS ONLY ABLE TO STOP BY PULLING ONTO THE GRASS WHILE APPLYING THE EMERGENCY BRAKE. I FOUND ONE BRAKE LINE ON THE FRONT DRIVER SIDE HAD RUSTED THROUGH, BUT NONE OF THE OTHERS HAD A LEAK AND THE BRAKE FLUID WAS STILL FULL. WITH ONLY ONE BRAKE LINE DAMAGED I LOST ALL BRAKING POWER.

I DRIVE A 2005 SIERRA 1500 4 WHEEL DRIVE. WHILE DRIVING ON THE FREEWAY THE TRUCK WENT FROM NORMAL 2 WHEEL DRIVE (D ON THE STEERING COLUMN), INTO NEUTRAL. I DID NOTHING TO CREATE THIS ACTION . THE SITUATION WAS EXTREMELY DANGEROUS. I DID PULL OFF AFTER OTHER DRIVERS ALMOST CRASHED DUE TO MY IMMEDIATE DECREASE IN SPEED. ONCE STOPPED I ATTEMPTED TO USE THE STEERING WHEEL SHIFT LEVER TO PUT THE TRUCK IN DRIVE OR PARK. IT WOULD NOT SHIFT, EVEN WITH FOOT ON THE BREAK. I NOTICED MY 4 WHEEL DRIVE SELECTOR SWITCH WAS NOT ILLUMINATED. I PUSHED THE 2WD BUTTON AND IT MADE A TERRIBLE NOISE. I TRIED THE AUTO 4WD BUTTON AND THEN WAS ABLE TO MOVE THE STEERING LEVER BACK TO PARK AND THEN TO D FOR DRIVE. NOW WHEN I SLOW TO TURN THE TRUCK DROPS INTO LOW 4 WHEEL DRIVE WHICH MAKES THE TRUCK SLOW TO 10 MPH MAX. THIS COULD GET ANYONE KILLED EVEN IF INITIALLY ONE HAD PLENTY OF TIME TO TURN. THERE ARE 100S OF FORUMS ON THE INTERNET DEALING WITH EXACTLY THIS PROBLEM YET NOTHING IS BEING DONE. HOW MANY PEOPLE HAVE DIED BECAUSE OF THIS PROBLEM AND NOT HAD THE CHANCE TO TELL? HOW MANY MORE MUST DIE BEFORE ANYTHING IS DONE?

CONCERNING GM 706 CASTECH CYLINDER HEADS/GM TSB 06-06-01-019B I HAVE A 2005 GMC SIERRA WHICH HAS SLOWLY BEEN LEAKING COOLANT FOR ABOUT 6 MONTHS. I HAVE HAD IT LOOKED AT AND THE DEALER INFORMED ME THAT I HAVE A 706 CASTECH CYLINDER HEAD THAT IS NOTORIOUS FOR CRACKING AND LEAKING. THE DEALER TOLD ME THERE WAS COOLANT INSIDE MY OIL AND RECOMMENDED REPLACING THE ENGINE. AS I HAVE BEGUN RESEARCHING THIS ISSUE I REALIZE THESE CYLINDER HEADS AFFECT MILLIONS OF GM VEHICLES AND LOYAL CUSTOMERS. GM HAS ISSUED A TSB AND ARE AWARE OF THE ISSUE AT HAND AND IN MY, AND MANY OTHER CUSTOMERS THIS SHOULD HAVE BEEN A RECALLED ITEM. I AM CALLING ON GM TO FIX THIS ISSUE/MISTAKE.
