1999 GMC SIERRA 1500 Complaints

BRAKE LINE FAILER DO TO POOR ROUTING FROM FACTORY AND SUBSTANDARD MATERIAL USED ON OEM LINES (BARE STEEL) . ALWAYS REPLACE OEM LINES WITH POWDER COATED AFTERMARKET OR STAINLESS "ONLY" INSPECT "ALL LINES & HARDWARE & CLIPS TO FRAME ECT FOR CORROSION". BRAKE FAILER OCCURED WHILE TOWING ANOTHER AUTO WITH TRAILER ATTACHED NO WARNING.

WHILE DRIVING ON A STREET IN MY NEIGHBORHOOD, WE FOUND THAT THE IGNITION SWITCH COULD BE MOVED TO THE "OFF" OR "ACCESSORY" POSITION WHILE DRIVING. NOTICED THAT STEERING, BRAKES, AND OTHER COMPONENTS BECAME DISABLED. LUCKILY WE WERE ABLE TO SAFELY MOVE THE VEHICLE TO THE ROADSIDE AND ASSESS THE SITUATION. A PROBLEM LIKE THIS COULD RESULT IN CATASTROPHIC SYSTEM FAILURE IN THE VEHICLE WHILE DRIVING AT HIGH SPEEDS, AND COULD CAUSE POSSIBLE DEATH IF WE WEREN'T AWARE OF THIS PROBLEM. PLEASE INFORM OTHER VEHICLE OWNERS OF THIS POSSIBLE DANGEROUS ISSUE.

WHEN COMING TO A STOPLIGHT, I APPLY THE BRAKES AND THE PEDAL GOES DOWN MORE THAN IT SHOULD, BUT I GET STOPPED. WHILE HOLDING THE BRAKE AND WAITING FOR THE LIGHT TO CHANGE THE BRAKE PEDAL GOES SLOWLY TO THE FLOOR. NEXT, I PULL INTO A PARKING LOT AND GET STOPPED. I PUT THE TRUCK IN PARK AN LOOK UNDER THE HOOD AT THE BRAKE MASTER CYLINDER, NO FLUID LEAKS, THEN I C LOOK AT EACH WHEEL, NO FLUID LEAKS. I GET TURNED AROUND AND HEAD HOME BECAUSE I KNOW SOMETHING IS WRONG. DRIVING HOME THE BRAKE PEDAL IS SOFT. I'M SOON HOME AND I PARK THE TRUCK BUT WITH THE MOTOR STILL RUNNING, I SLOWLY DEPRESS THE BRAKE PEDAL, IT GOES SLOWLY TO THE FLOOR, NEXT TIME I DEPRESS THE BRAKE PEDAL IT GOES TO THE FLOOR IN A SPLIT SECOND. I GET OUT AND INSPECT UNDER THE TRUCK. I SEE BRAKE FLUID LEAKING FROM THE LINES RUNNING DOWN THE FRAME RIGHT UNDER THE DRIVERS DOOR.

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE MADE AN ABNORMAL GRINDING SOUND FROM THE REAR END AFTER HITTING A POTHOLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE REAR DIFFERENTIAL WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE REAR DIFFERENTIAL WAS REPLACED FOUR TIMES. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 186,000.

BRAKE LINES RUSTED , ABS FAILURE ,GAS LINES RUSTED, TRANS COOLING LINES RUSTED. THESE WERE ALL FAILURES THAT NEEDED REPLACEMENT THROUGH THE YEARS I HAVE OWNED IT. NOW FRAME RUSTED AND CRACKED . TRUCK BASICALLY SHOT .

FRAME CROSS MEMBER BEHIND THE CAB IS RUSTED THROUGH. I HAVE OWNED VEHICLES IN "SALT" STATES AND NOT HAD THE FRAME RUST OUT. THIS SHOULD NOT BE CONSIDERED A "WEAR ITEM". THIS CAN LEAD TO A FAILURE WHEREBY THE FUEL TANK FALLS DOWN LEADING TO A HIGH RISK OF FIRE. THIS WAS FOUND DURING A REPLACEMENT OF THE BRAKE LINE (3RD SET) ASSEMBLY AND REMOVAL OF THE TRUCK BED.

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. WHILE THE VEHICLE WAS IN NEUTRAL, THE INSTRUMENT PANEL GAUGES FAILED AND FLICKERED WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

I AM THE ORIGINAL OWNER OF A 1999 GMC SIERRA THAT JUST HAD BRAKE LINE FAILURE ON 7/14/16 ON THE INTERSTATE THAT CAUSED AN ACCCIDENT. I HAD COMPLETE LOSS OF BRAKES, PEDAL TO THE FLOOR. I USED LOW GEAR AND PARK BRAKE TO MINIMIZE DAMAGE BUT STILL MADE CONTACT. IT IS CURRENTLY AT PATRIOT BUICK GMC IN WILLIAMSBURG VA FOR REPAIR WHERE I BOUGHT IT NEW. I FEEL ME HAVING TO PAY $1000+ FOR THE BRAKE LINE REPAIR AND NOW A COURT DATE AND INSURANCE ISSUES THAT ARE NOT MY FAULT. WE NEED TO DISCUSS GMC MAKING SOME RESTITUTION AS THERE IS NO RUST ANYWHERE ELSE AND THIS TRUCK HAS ONLY BEEN IN VA. I HAVE OTHER GM CARS FROM THE 60'S, 70S AND 2000S THAT HAVE NO RUST ISSUE. FUEL LINE WAS LEAKING AS WELL AND SOME NEEDED REPLACMENT.GM SERVICE REQUEST 8-2250924255 I ALSO HAD THE PS REAR BRAKE ROTOR SHIELD COME OFF AND SCRAPE MOVING PARTS LAST YEAR.
