2003 GMC Sierra 1500 Hd

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

I RECEIVED A LETTER FROM GENERAL MOTORS A FEW YEARS AGO ABOUT A SPEEDOMETER DEFECT. THE LETTER EXTENDED THE MANUFACTURES WARRANTY TO 7 YEARS 80,000 MILES ON THE GAUGE CLUSTER DUE TO DEFECTS. THE LETTER SAID IN BOLD UNDERLINED WORDS NOT TO BRING THE TRUCK IN IF IT IS NOT EXPERIENCING ANY PROBLEMS. IT IS NOW PAST THE EXTENDED WARRANTY AND THE SPEEDOMETER IS NOT WORKING. IT IS STUCK AT 80MPH AND WILL NOT MOVE. I TOOK IT TO THE GMC DEALERSHIP AND GM WILL NOT FIX THE UNIT SINCE IT IS TO OLD. I BELIEVE IT IS VERY DANGEROUS NOT TO KNOW HOW FAST YOU ARE GOING, THIS IS A KNOWN PROBLEM BY GM AND GM HAS NOT HAD TO HAVE A RECALL ON THE UNIT? GM SHOULD HAVE A RECALL FOR ALL THE AFFECTED CARS AND TRUCKS WITH THIS KNOWN PROBLEM. *TR
