2003 GMC SIERRA 1500 Complaints

ON 8/9/15 AT APPROXIMATELY 3:25PM AN INDIVIDUAL PULL OUT IN FRONT OF ME. WHEN I APPLIED THE BRAKES TO KEEP FROM HITTING HIM, THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR BOARD. I NOTICED AT THE TIME THE "SERVICE BRAKE SYSTEM" INDICATION WAS SHOWING ON THE DRIVER CID. I WAS ABLE TO DRIVE THE TRUCK TO A SAFE LOCATION AND PARK IT. I LOOKED UNDER THE VEHICLE AND NOTICED BRAKE FLUID ON THE GROUND UNDER THE RIGHT FRONT WHEEL. THE TOW TRUCK DRIVER ALSO CHECKED AND NOTICED BRAKE FLUID SHOOTING UP WHEN THE HOOD WAS UP. AT THAT TIME, HE NOTICED THE RIGHT FRONT BRAKE LINE HAD RUSTED THROUGH. THE TRUCK WAS THEN TOWED TO CUNNINGHAM GMC IN SPRINGFIELD, TN.

COMPLETE BRAKE FAILURE. ALL BRAKE LINES RUSTED OUT. HAD TO USE THE EMERGENCY BRAKE TO STOP. BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. ALL THE BRAKE FLUID WAS GONE. SPENT $1008 TO FIX THE VEHICLE. NO PREVIOUS WARNING, NO MESSAGE UNTIL THERE WAS THE COMPLETE BRAKE FAILURE. *TR

I AM AN ASE MASTER TECHNICIAN, I OWN AN AUTO/TRUCK REPAIR FACILITY. WE ARE A STATE OF OREGON AUTHORIZED DEQ REPAIR FACILITY, STATE OF OREGON DAS FLEET REPAIR FACILITY, US ARMY BASE VEHICLE REPAIR SHOP AND MORE. DRIVING MY TRUCK TO TACOMA WASHINGTON. I WAS TOWING A VEHICLE ON IN THE RIGHT SLOW LANE, AND "REDUCED ENGINE POWER" LIGHT CAME ON. ENGINE VIBRATED AND RUNS ON 1/2 CYLINDERS. CANNOT BRAKE OR STEER, TOTAL LACK OF POWER. SEMI-TRUCK NEARLY REAR ENDS ME AS I CANNOT GO OVER 10 MPH. NO THROTTLE RESPONSE, PERIOD. I WAS IN ROAD CONSTRUCTION ZONE AND EVERYONE WAS SLAMMING ON THEIR BRAKES TO AVOID PILE-UP AS I HAD NO SHOULDER TO PULL OVER TO. A MILE OR SO LATER I PULLED OVER, AND SHUT OFF TRUCK. RESTARTED FEW MINUTES LATER AND CEL WAS ON, BUT REDUCED ENGINE POWER LIGHTS OUT. I CONTINUED MY DRIVE, BUT NOW CAUTIOUSLY. IT HAPPENED 3 MORE TIMES GETTING TO TACOMA, AND 5 TIMES RETURNING BACK TO PDX. NOW AFRAID OF TRUCK. I FINALLY ARRIVED TO MY SHOP THE NEXT DAY AND SCANNED. CODES READ MAF FAIL, TPS FAIL. REPLACED THROTTLE PEDAL ASSY, THROTTLE BODY WITH POSITION SENSOR, WIRING TO THE THROTTLE BODY, CHECKED GROUNDS, REPLACED BATTERY AND MORE AS STATED BY GM TECH'S. STILL HAPPENS EVERY DAY. SEEMS LIKE UNDER LOW ACCELERATION, ENGINE BUCKS THEN CEL APPEARS AND REDUCED ENGINE POWER RETURNS. GM HAS NO OFFERS OR EXPLANATIONS FOR REPAIRS. I AM A CERTIFIED ASE MASTER TECHNICIAN AND HAVE NEVER SEEN OR HEARD OF THIS UNTIL I WENT ONLINE TO SEE IF THIS HAPPENS TO OTHERS. THIS IS A MAJOR PROBLEM WITH MOST GM OWNERS IN THE "FLY BY WIRE" TYPE OF VEHICLES. NO FIXES, NO HELP FROM GM. THIS HAS AND IS STILL OCCURRING EVEN TODAY 1/27/2015 WITH NO FIXES. VEHICLE IS BEING PARKED UNTIL FURTHER NOTICE AS THIS VEHICLE IS DANGEROUS TO DRIVE. ASE MASTER TECHNICIAN #[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).' *TR

WHILE DRIVING TO THE STORE I APPLIED THE BRAKE AND IT WENT STRAIGHT TO FLOOR WITHOUT ANY PRE-WARNING OF A BRAKE ISSUE. I WAS ABLE TO STOP WITHOUT CRASHING AND FOUND THAT THE BRAKE LINE ROUTED OVER THE GAS TANK RUSTED THROUGH SPILLING OUT BRAKE FLUID WHICH CAUSED THE BRAKE RESERVOIR TO EMPTY. AFTER DOING SOME RESEARCH NHTSA IS WELL AWARE OF THE RUSTED BRAKE LINES ON GM MODELS, SO I AM NOT TELLING YOU ANYTHING NEW. I EXPECT ALTERNATORS, STARTER MOTORS, AND OTHER MECHANICAL COMPONENTS TO FAIL AND NEED REPLACED BUT BRAKE LINES SHOULD BE MANUFACTURED USING STAINLESS STEEL. HOW CAN THIS BE ANY DIFFERENT THAN A CAR IGNITION TURNING OFF CAUSING POTENTIAL CRASHES AND LOSS OF LIFE. NHTSA SHOULD HAVE GM RECALL VEHICLES AND/OR REIMBURSE OWNERS FOR THIS HIGHLY POTENTIAL SAFETY ISSUE. *TR

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. WHILE DRIVING 40 MPH, THE CONTACT'S VEHICLE CRASHED INTO THE PASSENGER SIDE OF ANOTHER VEHICLE. THE AIR BAGS FAILED TO DEPLOY. THE CONTACT SUSTAINED INJURIES TO THE FACE, KNEE, AND BACK THAT REQUIRED MEDICAL ATTENTION. IN ADDITION, THE PASSENGER SUSTAINED HIP AND SHOULDER INJURIES THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 177,000.

TRUCK WAS BEING DRIVEN IN TRAFFIC AND AS APPROACHING STOP LIGHT AND BRAKES WERE APPLIED PETAL WENT ALL THE WAY TO FLOOR AND HAD TO SWERVE TO MISS STOPPED TRAFFIC. UPON INSPECTION BRAKE LINE ON DRIVERS FRONT SIDE OF TRUCK AND LAYING ON TOP OF THE FRAME WAS RUSTED ALMOST COMPLETELY IN HALF! QUICK THINKING AVOIDED ACCIDENT .THIS TRUCK HAS ONLY BEEN DRIVEN ON CITY STREETS AND NEVER OFF ROAD FOUR WHEELING AND FEEL THIS IS MANUFACTURING DEFECT AS STAINLESS STEELS LINES SHOULD NOT RUST IN HALF IF IN FACT THEY ARE STAINLESS STEEL TO BEGIN WITH.TRUCK IS AT GMC NOW TO BE REPAIRED. *TR

WHILE HAVING MY VEHICLE CHECK OVER FOR THE WINTER, THE MECHANIC INFORM ME THAT THE FRONT BRAKE LINES ARE VERY RUSTY AS WELL AS THE FUEL LINES AND THE COOLING LINES GOING TO THE TRANSMISSION. THIS SITUATION IS VERY DISTURBING SINCE I HAVE VERY LOW MILEAGE. THE TUBING USED FOR THE BRAKE AS WELL AS THE FUEL LINES SHOULD BE ABLE TO WITHSTAND RUSTING FOR THE LIFE OF THE VEHICLE. IF THE MATERIAL USED BY GM WAS NOT UP TO SPECIFICATION AS FAR AS CORROSION PROTECTION EITHER COMPENSATION TO REPAIR IT IS IN ORDER A RECALL SHOULD BE MADE.

TL* THE CONTACT OWNS A 2003 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE OPERATING THE VEHICLE, THE INSTRUMENT PANEL WOULD NOT FUNCTION PROPERLY.
