THE FAILURE PROGRESSIVELY WORSENED AND THE CONTACT HAD TO MEMORIZE IN WHAT GEAR THE VEHICLE WAS PLACED. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE.

IGNITION SWITCH IS STICKING IN RUN POSITION. I HAVE TO TURN THE SWITCH BACK AFTER CRANKING TO TURN OFF THE ABS /PARKING BRAKE LIGHT. TRIED A NEW SWITCH DIDN'T SOLVE THE PROBLEM. IS THIS PART OF THE RECALL PROBLEM. *TR

NOVEMBER 5, 2014: TURN KEY AND SYMPTOM OF A DEAD BATTERY. STARTER CLICKS ONCE. NO LIGHTS WILL WORK AT ALL. TOOK BATTERY OUT, CHARGED IT OVERNIGHT, AND HAD IT TESTED. TEST REVEALS BATTERY IS GOOD (SHOULD START VEHICLE) BUT WEAK (NEEDS A CHARGE). PUT BATTERY BACK IN, CONNECTED IT, PUT KEY IN, TURNED IT, AND VEHICLE STARTED EASILY. ............. NOV. 15, 2014: TURN KEY BUT, ELECTRICAL SYSTEM IS COMPLETELY DEAD. THEN, TAKE KEY OUT FOR FIVE MINUTES, PUT BACK IN, AND STARTS RIGHT UP LIKE NOTHING WRONG. *TR

THE DRIVE INDICATOR ON MY DASH BOARD CLUSTER DOES NOT LIGHT UP AND SHOW WHAT GEAR IM IN. CALLED BEFORE BECAUSE THERE IS A RECALL FOR THIS YEAR AND MODEL OF TRUCK BUT MY VIN WAS NOT INCLUDED IN RECALL BUT I HAVE THE SAME ISSUE. *TR

THE REAR SPEAKERS ON MY 2005 GMC SIERRA 1500 CREW CAB QUIT WORKING AND HAVEN'T CAME BACK ON. I HAVE BEEN TO DIFFERENT FORUMS AND THIS SEEMS TO BE A VERY COMMON OCCURRENCE. *TR

SPEEDOMETER SHOWS INCORRECT SPEED BY APROX. 20 MPH LESS THAN THE ACTUAL SPEED AT TIMES. *TR

SPEEDOMETER READING ERRATICALLY. 20MPH WHEN PARKED, SOMETIMES 40 WHEN PARKED. UNABLE TO DETERMINE ACTUAL SPEED. APPARENTLY THIS IS AFFECTING THOUSANDS OF GM VEHICLES AND GM KNOWS ABOUT THIS ISSUE BUT WON'T DO ANYTHING ABOUT IT. MAYBE A CLASS ACTION LAWSUIT IS IN ORDER? A SILENT RECALL IS IN PLACE IF YOU HAVE LESS THAN 80K MILES, IF YOUR VEHICLE FALLS WITHIN THE RANGE OF VIN #'S, IF IT HAPPENED ON A DAY THAT DOESN'T END IN Y. GM NEEDS TO BE RESPONSIBLE AND STAND BEHIND THEIR PRODUCT. ESPECIALLY IF THEY KNOW ITS A SAFETY ISSUE. *TR

I BOUGHT MY GMC USED IN 2008 AND I HAD NO PROBLEMS UNTIL A JUNE OF 2012 WHEN MY SPEEDOMETER STARTED TO GET MY SPEED TOTALLY WRONG. AT TIMES IT WOULD SAY I WAS DRIVING OVER 120 MPH OR WHEN IN IDLE IT WOULD EVEN SAY THE SAME THING. THE SPEEDOMETER PICKS A DIFFERENT SPEED DAILY. JUST A FEW WEEKS AGO IN JULY OF 2012 MY GAS GAUGE WENT COMPLETELY OUT SO I HAVE NO IDEA HOW MUCH GAS IT LEFT IN MY TRUCK. I HAVE TO GUESS BY MILEAGE NOW IN HOPES THAT MY ELECTRICAL DOESN'T GO COMPLETELY OUT NOW. *TR

ODI #10403836, 2005 GMC 1500 SIERRA, VIN#, COMPLETE FAILURE OF DASH INSTRUMENTS, STARTED WITH THE OIL GAUGE, THEN THE RPM INDICATOR, NOW THE SPEEDOMETER, RUNS UP TO 120 MPH SEVERAL TIMES A WEEK ONLY GOING AT UNKNOWN, UNSAFE SPEED WHICH I CAN ONLY ASSUME TO BE THE LEGAL LIMIT OF 70 MPH, THIS IS A SAFETY ISSUE AS WELL AS A MONETARY LOSS FOR ACCIDENTS AND OR SPEEDING TICKETS. IN ADDITION THE INSTRUMENT LIGHT FOR THE TRANSMISSION DOES NOT WORK AND YOU CAN NOT TELL WHAT GEAR YOU ARE IN ANOTHER POTENTIALLY DANGEROUS SITUATION, ON TOP OF THAT THE CHECK ENGINE LIGHT COMES ON REPEATEDLY CAUSING MINOR REPAIR COSTS EACH TIME IT OCCURS. THERE HAS TO BE CUSTOMER RECOURSE, WHEN THIS ORIGINALLY STARTED THE DEALERSHIP STATED THAT NOT TO WORRY AS SOON A RECALL WOULD BE ISSUED AS IT HAD FOR THE PRIOR YEARS, AS YET NO OFFICIAL RECALL OTHER...

TRUCK IS NOW 6 YEARS OLD, JUST OVER 70,000 MILES. 3 TO 4 YEARS AGO (MAYBE MORE) THE #5 SPEED ON THE AIR SYSTEM BLOWER STOPPED WORKING. PERHAPS LAST SUMMER OR FALL, I CHECKED THE FUSES: ALL GOOD. I FINALLY FOUND THE WIRING HARNESS PLUG TO THE FAN AND FOUND THE #5 LINE HAD MELTED INSULATION AND THE SURFACE OF THE CONTACT PRONGS BLACKENED. I SANDED THEM AND REINSTALLED THE PLUG. ALL SPEEDS WORKED, FOR A WHILE, BUT SOON BECAME INTERMITTENT. THEN ALL SPEEDS STOPPED WORKING TOTALLY. AT LAST, I REMEMBERED THAT I STILL HAD AN EXTENDED WARRANTY WITH MASTERTECH, CHECKED IT AND WAS ABLE TO GET THE HARNESS REPLACED UNDER THE WARRANTY. THE WORKMAN WHO DID THE REPAIR SAID THAT THIS ITEM WAS A COMMON PROBLEM WITH THE 2005 SIERRA. WHILE I DO NOW HAVE A WORKING FAN CONTROL, I AM AFRAID TO USE THE #5 FAN SPEED. *TR

SPEEDOMETER DOESN'T WORK CORRECTLY, READING 60 MPH WHEN WE WERE TRAVELING APPROX 40. ALSO BULBS BURNED OUT IN IT MAKING IT UNREADABLE AT NIGHT. BULBS ARE NON-REPLACEABLE IN THIS INSTRUMENT CLUSTER, SO YOU NEED TO REPLACE ENTIRE CLUSTER TO FIX BULB ISSUE. POOR DESIGN, EXPENSIVE, AND ANNOYING PROBLEM AT ONLY 99,000 MILES. *TR

SPEEDOMETER FLUXUATE SPORADICALLY, WRONG SPEED SHOWING. TOOK TO DEALER, DIAGNOSIS AS COMPONENT FAILURE. GMC ACKNOWLEDGE PROBLEM, BUT REFUSE TO RECALL. DEALER WILL REPLACE ODOMETER IF LESS THAN 80,000 MILES. *TR

SPEEDOMETER FAILED AT 68,000 MILES. IT STICKS ALL THE WAY PAST 120 MPH. CAN'T SEE HOW FAST I'M GOING, DEALER REFUSES TO FIX IT. TRIED THREE DEALERS. *TR

SPEEDOMETER FAILURE. VERY DANGEROUS - WHILE TRYING TO RESUME SPEED ON AN INTERSTATE I NEARLY CRASHED INTO THE INTERSTATE BARRIER/WALL ON A CURVE THE OTHER NIGHT BECAUSE THE SPEEDOMETER READ 70. I THEN SLOWED TO "STAY WITH THE FLOW" AND SPEEDOMETER READ 35 (ASSUMING TRAFFIC WAS DRIVING THE SPEED LIMIT OF 70). NOW IT START OF OK AND THEN BEFORE YOU KNOW IT WILL START TO DROP AND AFTER A STOP WILL STAY AT 0 WHILE DRIVING INTERSTATE SPEEDS, WILL STICK AT 55 WHEN PROBABLY GOING ABOUT 10. IT IS ALL OVER THE PLACE. THE FAILURE IS NOW DAILY AND IS FAR TOO DANGEROUS TO MY FAMILY AND I TO DRIVE. HOPE THIS GETS RECALLED QUICKLY BEFORE IT CAUSES DEATHS. *TR

TL*THE CONTACT OWNS A 2005 GMC SIERRA 1500. WHILE DRIVING AT 65 MPH, THE CONTACT NOTICED THAT THE ABS LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. AN HOUR LATER, THE CONTACT NOTICED THAT THE VEHICLE DISPLAYED DIFFICULTY STOPPING. AFTER INSPECTING THE VEHICLE, THE CONTACT NOTICED THAT THE DRIVER SIDE TIRE WAS TILTED AND SMOKE AND FLAMES HAD BEGAN RISING FROM BEHIND THE WHEEL. THE CONTACT CALLED THE FIRE DEPARTMENT BUT NO REPORT WAS FILED. THE VEHICLE HAD NOT BEEN INSPECTED AT THE TIME OF THE COMPLAINT. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 49,000. UPDATED 07/26/10. *LJ UPDATED 08/06/10*JB

WIRING HARNESS BETWEEN FAN SWITCH AND FAN MOTOR GET VERY HOT AT THE CONNECTION AND MELTS THE CONNECTION. *TR

SPEEDOMETER WORKS OCCASIONALLY, UNKNOWN SPEED TRAVELING. *TR

WE OWN A 2005 GMC SIERRA AND THE SPEEDOMETER HAS GONE OUT. WAS INFORMED IT IS AN INTERNAL GAUGE CLUSTER THAT HAS GONE OUT AND IT WILL TAKE $400-$600 TO FIX IT. I HAVE RESEARCHED ONLINE AND THIS HAS BEEN A PROBLEM WITH TRUCKS SINCE AT LEAST 2007. THERE SHOULD BE A RECALL ON THIS AND THE CUSTOMERS SHOULD NOT HAVE TO PAY FOR THIS TO BE FIXED. GMC REFUSES TO DO A RECALL AND SAYS THAT THERE IS NOTHING THEY CAN DO. *TR

MY SPEEDOMETER FAILED IN DEC OF 2009 ON MY GMC SIERRA PICKUP. IN THE COLD IT ALWAYS REGISTERS 0 MPH AND WILL START TO WORK AFTER AN HOUR ON THE ROAD. *TR

SPEEDOMETER HAS SUDDENLY STOPPED WORKING ON MY 2005 GMC SIERRA 1500. I HAVE LEARNED THERE IS A RECALL FOR MODEL YEARS 2003-2004. SEEMS LIKE THE PROBLEM MAY EXTEND TO FURTHER YEARS. *TR

THE SPEEDOMETER AND FUEL GAUGE ON MY 2005 GMC SIERRA 1500 CREW CAB ARE ERRATIC AND OCCASIONALLY NON OPERATIVE. SPEEDO READS 120 MPH AT TIMES WHEN THE VEHICLE IS STOPPED. SOMETIMES DOES NOT READ AT ALL, STAYS AT ZERO WHEN DOING FREEWAY SPEEDS. FUEL GAUGE READS EMPTY WHEN 1/4 TANK, THEN AFTER A RESTART WILL SHOW PROPER(?) LEVEL. *TR

05 GMC SIERRA SPEEDOMETER ERRATIC AT FIRST,15,000 ML.,NOW AT 62,000 ML. DOESN'T WORK. I WAS GOING 50 AT A STOP SIGN. I HAVE MY OWN BUSINESS AND PULL TRAILERS W/ EQUIPMENT AND THE RIGHT SPEED IS CRITICAL FOR THE TOWING WEIGHTS. THE LAW ENFORCEMENT AGENCIES WILL NEVER TAKE A FAULTY SPEEDOMETER AS A REASON FOR GOING OVER THE SPEED LIMIT. INTERSTATE DRIVING IS AT A MINIMUM BECAUSE GOING WITH THE FLOW WILL MEAN OVER HEATING OF THE SMALL TRAILER TIRES ON THE TILT BED TRAILER. NO ACTION YET IT JUST QUIT TODAY,1-4-2010 , AND I AM FILING THIS COMPLAINT TO ADD TO THE NUMBERS OF OTHERS THAT HAVE ALREADY FILED. *TR

SPEEDOMETER STICKS AND DOESN'T RETURN TO 0 AND CONTINUES TO RISE EVERY TIME THE VEHICLE ACCELERATES UNTIL THE SPEEDOMETER IS PEGGED OUT AND THEN IT STICKS THERE. *TR

THE SPEEDOMETER OF MY GMC SIERRA 1500 IS ERRATIC WHEN IT IS WET OUTSIDE. WHEN THE VEHICLE IS PARKED AND THE IGNITION KEY IS IN MY POCKET THE SPEEDOMETER READS ANYWHERE FROM 40 TO 50 MPH. WHILE DRIVING THE SPEEDOMETER INDICATES UP TO 120 MPH. HOW MANY PEOPLE HAVE TO COMPLAIN ABOUT THIS SAFETY CONCERN BEFORE SOMETHING IS DONE. A SEARCH OF YOUR DATABASE INDICATES MANY COMPLAINTS. HELP. *TR

THE CONNECTOR THAT PLUGS INTO THE BLOWER MOTOR UNDER THE GLOVE BOX BECAME TOO HOT AND MELTED THE PLASTIC RESULTING IN THE A/C AND HEAT NOT TO WORK (THIS INCLUDES THE WINDSHIELD DEFROSTER). I'VE BEEN LOOKING UP PROBLEMS AND SOLUTIONS AND FOUND THAT THIS IS A RECURRING PROBLEM WITH GMC AND CHEVY TRUCKS YET THERE HAS NOT BEEN ANY RECALL, IN FACT THE DEALERSHIPS HAVE AN EXTREMELY OVERPRICED KIT TO FIX THEIR FAULTY WIRING. ABOUT 66,000 MI. *TR

GMC SIERRA 2005 SPEEDEMOTER BAD, CANNOT TELL WHAT SPEED I'AM GOING. 37.000 MILES ON TRUCK... *TR

SPEEDOMETER STOPPED WORKING AT 20000 MILES. IT WAS WORKING FINE THEN STARTED TO WORK ONLY OCCASIONALLY AND HAS NOW COMPLETELY STOPPED WORKING. WE HAVE NOT HAD IT REPAIRED AS OF YET. IT IS VERY UNSAFE TO DRIVE NOT KNOWING WHAT SPEED YOU ARE TRAVELING AT, PLUS CAN RESULT IN TRAFFIC VIOLATIONS CAUSING YOUR INSURANCE TO INCREASE. *TR

I'M CURRENTLY AT 84,000 MILES ON MY 2005 GMC SIERRA, AND WHEN STOPPED WITH THE TRUCK IN PARK MY SPEEDOMETER IS SHOWING 90MPH THEN PROCEEDS UP FROM THERE WHILE DRIVING. I THINK THERE'S SOMETHING THAT NEEDS TO BE DONE. I HAVE SEVERAL FRIENDS WITH THE SAME YEAR MODEL VEHICLES MANUFACTURED BY GM. ALL HAVE THE SAME PROBLEMS. TALKED TO A DEALER ABOUT GETTING IT FIXED THEY TOLD ME IT WAS GOING TO COST 300 FOR THE PART, AND 200 DOLLARS TO HAVE IT PROGRAMMED.... *TR

I OWN A 2005 GMC SIERRA AND THE SPEEDOMETER HAS FAILED. I OWN A GPS SO I USE THIS TO HELP DETERMINE THE SPEED I AM TRAVELING. I BROUGHT MY VEHICLE INTO THE DEALER ON SEVERAL OCCASIONS AND CONTACTED GM AND THEY STATED THEY COULD NOT HELP ME THAT I WOULD HAVE TO PAY $380.00 TO GET IT REPAIRED. TWO DAYS AFTER BRINGING INTO MY LOCAL DEALER I RECEIVED A LETTER IN THE MAIL STATING THERE WAS A CLASS ACTION LAWSUIT AGAINST GM FOR DEFECTIVE SPEEDOMETERS ON CERTAIN MAKES AND MODELS. *TR

I WAS DRIVING MY 2005 GMC SIERRA 1500 TRUCK AND THE CAB FILLED WITH SMOKE THE A SMALL FIRE DEVELOPED ON THE WIRE BUNDLE THAT CONNECTS TO THE FAN BLOWER UNDER THE DASH PASSENGER SIDE. I HAD TO PULL OVER AND PRY THE BURNT CONNECTOR OFF OF THE RESISTOR / BLOWER HOOK UP. THE FUSE DID NOT WORK AND THE CONNECTOR CONTINUED TO BURN UNTIL I SHUT OFF THE TRUCK AND REMOVE THE CONNECTOR. I PLAN TO TAKE THE TRUCK INTO SKILLMAN GMC SINCE A FUSE DID NOT BLOW PRIOR TO THE BURNING OF THE WIRING. ALSO I DID A BRIEF SEARCH AND FOUND OTHERS HAD SIMILAR ISSUES WITH EITHER THE GMC SIERRA AND THE CHEVY SILVERADO TRUCK. *TR

2005 GMC SIERRA - IF THE VEHICLE SITS FOR 3-4 DAYS WITHOUT BEING DRIVEN, THE BATTERY GOES DEAD. NOTHING HAS BEEN LEFT ON. *JB

ELECTRICAL SYSTEM, ALL MY TRUCK LIGHTS DIM VERY LOW WHEN I ROLL THE WINDOWS UP OR DOWN WHEN DRIVING, WHEN I HIT THE BRAKES ALL LIGHTS DIM AND VOT. DROPS WE HAVE TAKEN IT IN TO THE SHOP A LOT FOR THIS AND STILL NO FIX. SERVICE ENGINE LIGHT STAYS ON AND MY TEMPERATURE GAUGE DOESN'T WORK I TOOK IT IN AND THEY SAID THIS PROBLEM IS ONLY IN ALASKA AND THERE IS NO FIX. FRONT DIFF HAS BEEN A PROBLEM SINCE THE DAY WE PICKED IT UP THE HAVE FIXED DIFFERENT THINGS ON IT. *JB
