2004 GMC SIERRA Complaints

BRAKE LINE FAILURE AS AN EMERGENCY STOPPING PROCEDURE WAS IN PLACE. VEHICLE EVENTUALLY STOPPED, BUT REAR ENDED THE FORWARD VEHICLE. BRAKE LINE CORROSION IN HARD PIPING WAS DIAGNOSED AS THE PROBLEM AS THE HARD BRAKE LINE RUPTURED. *TR

WHEN COMING TO A RED LIGHT I TRIED TO STOP MY TRUCK. UPON PRESSING THE BRAKE PEDDLE THE FIRST TIME I STARTED TO SLOW DOWN. UPON PRESSING THE BRAKE PEDDLE THE SECOND TIME, THE PEDDLE WHEN TO THE FLOOR AND DID NOT SLOW ME DOWN. I HAD TO RUN THE RED LIGHT AND US MY E BRAKE TO SLOW DOWN AND FINALLY STOP AT A GAS STATION. WHILE WAITING FOR AAA TO PICK ME UP NOTICED BRAKE FLUID COMING OUT FROM UNDER DRIVERS SIDE. TRUCK WAS TOWED TO MY SON'S HOUSE. AFTER LOOKING UNDER THE TRUCK HE TOLD ME THE BRAKE LINES FROM THE FRONT OF THE TRUCK HAD BROKEN. HE SUGGESTED WE REPLACE ALL THE BRAKE LINES, WHICH WE DID. ALL THE ORIGINAL LINES WERE ROTTING AWAY. WHEN WE REMOVED THE BRAKE LINES THEY ALL BROKE INTO PIECES . WE REPLACED ALL THE ORIGINAL LINES WITH STAINLESS STEEL LINES AT COST OF $400.00 PLUS I FOUND A FRONT AND A REAR CALIPERS FROZEN, SO I REPLACED ALL THE BRAKES AND CALIPERS. THERE IS NO WAY THE BRAKE LINES ON A 8 YEAR OLD TRUCK SHOULD BE FOUND IN THIS SHAPE. THE ORIGINAL LINES LOOKED LIKE ALUMINUM COATED STEEL. *TR

TL* THE CONTACT OWNS A 2004 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE JERKED VIOLENTLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 90,000....UPDATED 10/19/12 *BF UPDATED 10/25/12

I LEFT MY HOUSE FOR WORK AND APPROX. 3 BLOCKS FROM MY HOUSE I ATTEMPTED TO SLOW DOWN TO MAKE A RIGHT HAND TURN. I PRESSED ON THE BRAKES AND THE PEDAL WENT ALL THE WAY TO THE FLOOR. I HAD NO BRAKES. AT THIS TIME AND THIS WAS THE FIRST TIME, THE BRAKE LIGHT ON THE DASH CAME ON. I WAS DRIVING AT 30 MPH WITH NO BRAKES, I COASTED INTO A PARKING LOT AND USED THE PARKING BRAKE TO STOP THE TRUCK. OUTSIDE AND UNDER THE DRIVERS DOOR OF THE 2004 SIERRA EXTENDED CAB THERE WAS BRAKE FLUID LEAKING. THE 8 YEAR OLD TRUCK HAD RUSTED BRAKE LINES THAT FAILED. MY CONCERN IS THAT I LOST ALL BRAKES WITHOUT WARNING. AFTER A LITTLE RESEARCH I NOTICED MANY OF THESE TRUCKS HAVE THE SAME PROBLEM. THEY ARE 5000 POUND TORPEDOS ON THE ROAD AND WITHOUT WARNING. WILL SOMETHING BE DONE BEFORE A SERIOUS ACCIDENT OCCURS? I TRIED CONTACTING GMC VIA THEIR WEBSITE E-MAIL BUT AN ERROR MESSAGE OCCURRED. TRY A COMPLAINT ON THEIR SITE.....IT DON'T WORK!!! *TR

I WAS LEAVING MY DRIVEWAY AND COMPLETELY LOST ALL BRAKES AND COULD NOT STOP. I HAD TO SLAM ON THE PARKING BRAKE TO STOP. A BRAKE LINE BLEW. ALL THE BRAKE LINES AND FUEL LINES ARE COMPLETELY ROTTED.THIS VEHICLE ISN'T EVEN 10 YEARS OLD YET. THE FUEL LINE AND BRAKE LINES ARE A MAJOR SAFETY ISSUE. THIS TRUCK IS A 2500 AND I USE IT FOR TOWING TRAILERS IF THAT BRAKE LINE WENT WHILE TOWING IT WOULD HAVE BEEN A MAJOR ACCIDENT. THE ENTIRE UNDERNEATH OF THIS TRUCK IS SO RUSTED THE FRAME BRAKE LINE AND FUEL LINES ARE TERRIBLE. SOMEONE IS GOING TO GET KILLED FROM GM'S CHEAP STEEL. *TR

ALL BRAKE LINES ARE RUSTED ABOUT INTO... ONE BUSTED, I HAD BEEN ON INTERSTATE FOR TWO HOURS AND LUCKILY I PULLED INTO MY DRIVEWAY AND LOST ALL BRAKES. BRAKE LINES SHOULD NOT BE IN SUCH A RUSTED STATE FOR THIS TRUCK, GM SHOULD BE MADE TO RECALL FOR THIS PROBLEM ... THIS IS LIFE THREATENING UNDER SUCH CONDITIONS! AND SHOULD BE ADDRESSED AS SOON AS POSSIBLE. *TR

I WAS COMING DOWN A HILL NEAR MY HOME & TAPPED ON THE BRAKES TO SLOW DOWN. SUDDENLY ALARM BELLS STARTED DINGING, THE ENGINE WARNING LIGHT CAME ON & "SERVICE BRAKES IMMEDIATELY" POPPED UP ON THE MESSAGE CENTER. THE BRAKE PEDAL WAS SLIGHTLY SOFTER THAN NORMAL BUT I MADE IT HOME OK. THE FOLLOWING DAY I TOOK THE TRUCK TO MY MECHANIC TO HAVE HIM CHECK OUT THE PROBLEM. MUCH THE SAME AS MANY OTHERS HAVE COMPLAINED ABOUT, ALL FOUR BRAKE LINES BETWEEN THE MASTER CYLINDER & THE ABS CONTROLLER WERE BADLY RUSTED OUT WHILE ONE HAD FAILED COMPLETELY (CAUSING THE ALERT/ALARM). THE LINES FROM THE ABS CONTROLLER TO THE INDIVIDUAL WHEELS ARE ALSO COMPLETELY RUSTED BUT AS OF NOW HAVEN'T FAILED. HE REPLACED THE ONE RUPTURED LINE & SUGGESTED THAT I HAVE THE OTHERS DONE AS SOON AS POSSIBLE AS THEY ALL LOOK VERY BAD. LOOKING AT THE UNDERCARRIAGE OF THE VEHICLE THERE WAS VERY LITTLE OVERALL RUST ON ANY OTHER COMPONENTS OR THE FRAME, JUST ON THE BRAKE LINES. ESTIMATED COST FOR REPLACING ALL THE LINES AS NEEDED - $800. *TR

BRAKE FLUID ALL LEAKED AND I BARELY STOPPED THE TRUCK ON MY HOME DRIVEWAY. DEALER SAYS I NEED TO REPLACE ALL FOUR METAL BRAKE LINES. *TR

THE MANUAL SHIFT ON THE FLY SYSTEM (MSOF) WITH NEW VENTURE GEARS AUTOMATIC TRANSFER CASE IS DEFECTIVELY DESIGNED. A METAL ANTI-RATTLE CLIP WORKS IT WAY THROUGH THE CASE HOUSING, CAUSING ALL FLUID TO LEAK OUT OF THE TRANSFER CASE. THE CLUTCHES THEN BURN OUT RENDERING THE TRANSFER CASE USELESS. THE RESULT IS NO 4 WHEEL DRIVE (NO POWER TO FRONT WHEELS) WHEN SHIFT ON THE FLY IS PRESSED, LEAVING DRIVER SLIDING ON SNOW OR ICE--WHICH HAPPENED TO ME IN A NEAR WRECK. I RECOVERED FROM THE SLIDE AND GOT THE VEHICLE HOME AND THEN TO A REPAIR SHOP (ONCE THE SNOW MELTED) FOR A NEW TRANSFER CASE (REPAIR ONGOING). DRIVERS MAY RELY ON THE 4WD IN INCLEMENT WEATHER TO CERTAIN CONDITIONS AND BE INJURED WHEN THE 4WD DOES NOT ENGAGE DUE TO THE DEFECTIVE TRANSFER CASE. THIS CONDITION IS SO COMMON IN THE GMC SIERRA/CHEVY SILVERADO THAT THERE ARE NOW PARTS TO PREVENT THE CLIP FROM EATING THROUGH THE HOUSING: THE MERCHANT AUTOMOTIVE UPGRADE PROVIDES THE SOLUTION THAT SHOULD BE DONE TO ALL 4WD MODELS WITH THE DEFECTIVE TRANSFER CASES: HTTP://WWW.YOUTUBE.COM/WATCH?V=NJ5ZS8WOMNK&FEATURE=RELATED THE CONDITION WOULD NOT IMPACT 2WD MODELS, HOWEVER. IT SHOULD BE REMEDIED BY GENERAL MOTORS. *TR

BRAKE LINES RUSTED THROUGH AT LEFT SIDE JUST BELOW DRIVERS DOOR, WHICH RESULTED IN A LOSS OF BRAKES!!!!! AFTER FURTHER INSPECTION ALL BRAKES LINES ARE SEVERELY RUSTED AND MUST BE REPLACED. THIS IS ONLY A 2004 TRUCK!!!!!!!! *TR
