2003 GMC Sierra 1500 Hd Problems

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.

BRAKE LINE FAILURE DUE TO EXCESSIVE CORROSION OF THE LINE. AFTER REPLACING THE LINE MYSELF, I PERFORMED A TEST RUN AND YET ANOTHER LINE FAILED DUE TO THE CORROSION PROBLEM. THE ISSUE HAS BEEN ADDRESSED BY GENERAL MOTORS IN CANADA, BUT HAS NOT BEEN ADDRESSED IN THE US. I FEEL THAT TEN YEARS AND ONLY 84,000 MILES IS NOT AN ACCEPTABLE TIMEFRAME/MILEAGE TO BE EXPERIENCING BRAKE LINE CORROSION FAILURE IN THE STATE OF VIRGINIA. IN FACT THE ENTIRE UNDERCARRIAGE OF THE VEHICLE IS CORRODED FAR WORSE THAN MY 2000 HONDA CIVIC WHICH HAS 175,000 MILES ON IT. GENERAL MOTORS SHOULD BE FORCED TO ADDRESS THE CORROSION ISSUES WITH THE SIERRA PICKUP LINE IN THE US. *TR

I EXPERIENCE AN INTERMITTENT PROBLEM WITH MY TRUCK THAT FLASHES AN ERROR CODE "REDUCED ENGINE POWER". THIS IS TIED TO ERROR CODE P1516. USUALLY THIS PROBLEM OCCURS IN COLDER PARTS OF THE YEAR, AND ON A COLD SOAKED ENGINE, BUT IT HAS HAPPENED OTHER TIMES AS WELL. AS SOON AS THE ERROR OCCURS THE THROTTLE SHUTS AND LEAVES THE VEHICLE WITH ONLY INERTIA TO ATTEMPT TO GET OFF THE ROAD. THIS HAS HAPPENED TO ME ON THE INTERSTATE, AND THOUGH I HAVE NOT HAD AN ACCIDENT YET, I DO CONSIDER IT DANGEROUS. I HAVE TAKEN THE VEHICLE TO MY LOCAL DEALER AND INDEPENDENT MECHANICS, AND THEY HAVE BEEN UNABLE TO RESOLVE THE PROBLEM. THIS SEEMS TO BE A WIDESPREAD PROBLEM WITHOUT A SOLUTION. *TR

A FIRE IN THE DASH BOARD IN THE MIDDLE OF THE NIGHT WHILE THE VEHICLE WAS PARKED IN OUR BACK YARD DRIVE WAY. DASH BOARD AREA MELTED WHERE THE HEAD UNIT AND CIGARETTE LIGHTER IS LOCATED. BURNED THE HEAD LINER WHERE A COMPARTMENT WAS. THE WINDSHIELD CRACKED FROM THE INSIDE/OUTWARD. BURNED SPOTS ON THE SEATS FROM THE DASH BOARD BURNING. EVERYTHING IN THE FRONT OF THE CAB IS BLACK. ALL WINDOWS WERE UP AND TRUCK WAS LOCKED. FIRE HAPPENED IN THE MIDDLE OF THE NIGHT WHEN WE WERE ALL ASLEEP. WE DROVE THE TRUCK ON 2/20/14, WITH NO PROBLEMS. PARKED IT IN THE DRIVE WAY ABOUT 5:30 PM ON 2/20/13. NEXT MORNING SAW THAT THE WINDSHIELD WAS CRACKED, BUT FACING OUTWARD. OPENED THE DOOR AND WAS IN SHOCK. THIS TRUCK IS VARY SPECIAL TO US. IT BELONGED TO OUR SON THAT PAST AWAY 1/10/2013. CAN'T SEEM TO FIND IF THERE WAS ANY RECALLS FOR 2003 SIERRA 1500 HD CREW CAB. *TR
