1). Dash light stays on constantly and reads SERVICE AIR BAG. This was checked out at an auto repair shop. If air bag doesn't respond, it could be fatal. 2). Check engine light is always on. Was checked out at an auto repair shop and repaired on 10/19/2021. 3). Right engine exhaust manifold is cracked and leaking exhaust. Was checked out at a muffler repair shop. In time I'm afraid fumes my leak into the truck cab. 4). A brake line ruptured and was repaired on 09/02/2020.

TL* THE CONTACT OWNS A 2005 GMC SIERRA. THE CONTACT STATED THAT WHILE THE VEHICLE WAS PARKED AND TURNED OFF THE FOG LAMPS ACTIVATED INDEPENDENTLY. WHILE INSPECTING THE VEHICLE IT WAS DISCOVERED THAT THE DRIVER SIDE DASHBOARD HAD MELTED AND A BURNING ODOR WAS PRESENT INSIDE THE CABIN OF THE VEHICLE. THE FIRE DEPARTMENT WAS NOT NOTIFIED. THE CAUSE OF THE FAILURE WAS NOT YET DETERMINED. THE MANUFACTURER AND LOCAL DEALER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 160,000.

THE PASSIVE ALARM SYSTEM IS MALFUNCTIONING APROX EVERY 10 CRANKS. WHEN THIS HAPPENS YOU ARE STUCK FOR AT LEAST A HOUR BEFORE IT WILL START. DEALERSHIP CAN NOT FIND THE PROBLEM AND A COMPLAINT WAS MADE TO GMC COMPLAINT DEPARTMENT I HAVE CHANGED NUMEROUS PARTS M SWITCHES AND BOXES ,

CHARGING SYSTEM FAILURE MESSAGE KEEPS COMING UP ON VEHICLE...REPLACED ALTERNATOR THREE WEEKS AGO AND IT SEEMS TO SOLVE THE PROBLEM...FOR A WHILE AT LEAST...TWO NIGHTS AGO TRUCK DIED...REPLACED BATTERY WITH A BRAND NEW ONE YESTERDAY AND TRUCK IS STILL SITTING ON THE SIDE OF THE ROAD AS BATTERY IS NOT GETTING CHARGE FROM ALTERNATOR.

Instrument panel stops working from time to time. My Guages go crazy. My rpm and speedometer mess up and can't tell how fast I'm going. This has been going on for a few years now. My airbag sensor light is on and was In a light wreck few months ago. Hit pretty hard on front end of truck and yet neither one of my airbags deployed.

THE SPEEDOMETER IS FAILING. IT WORKS ERRATICALLY. IT EVENTUALLY GOES TO ZERO AND STAYS THERE UNTIL I STOP AND RESTART THE TRUCK OR LET IT SIT OVERNIGHT.

THE GEAR SHIFT INDICATOR LIGHT HAS GONE FROM DIM TO NO LIGHT AT ALL SO YOU CAN NOT SEE WHAT GEAR YOU ARE IN. THIS HAPPENS ANYTIME THE VEHICLE IS RUNNING.

ALWAYS TURNS OFF WHILE DRIVING OR WHILE AT IDLE

THE RUNNING LIGHT SOCKETS BURNED OUT. I CAN SEND YOU THE BURNED OUT SOCKET BUT NEED AN ADDRESS.

2005 GMC SIERRA. CONSUMER WRITES IN REGARDS TO VEHICLE SPEEDOMETER STOPPED WORKING. *SMD

TODAY WHEN I PARKED MY GMC SIERRA 2500HD, I TURNED OFF THE KEY SWITCH AND I NOTICED MY BLOWER MOTOR WAS STILL RUNNING. AFTER A SHORT PERIOD OF TIME I SMELT SOMETHING BURNING. I WENT OUT UNDERNEATH THE HOOD OF MY VEHICLE LOCATED THE FUSE BOX AND REMOVED THE 40 AMP BLOWER MOTOR FUSE AND THAT SHUT DOWN THE HEATER AND THE SMELL STARTING GOING AWAY. IT WAS 19 DEGREES HERE IN OKLAHOMA AT THE TIME OF INCIDENT. I DID SOME RESEARCH ON THE INTERNET AND GOT SEVERAL HITS ABOUT GMC TRUCKS THAT EXPERIENCED THE SAME ISSUE EXCEPT SOME OF THE VEHICLES BURNED COMPLETELY TO THE GROUND. I ALSO GOT INFORMATION FROM THE INTERNET THAT GENERAL MOTORS OF CANADA RECALLED ALL THERE GM PRODUCTS THAT HAD THE SAME BLOWER MOTOR ASSEMBLY. I FILED A COMPLAINT WITH GENERAL MOTORS, DETROIT. THEY SAID THEY HAD NO RECALLS. *TR

TL*THE CONTACT OWNS A 2005 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE AT A STOP SIGN, ALL THE LIGHTS ON THE INSTRUMENT PANEL BEGAN FLASHING INTERMITTENTLY. ALSO, THE HEADLIGHTS TURNED ON AND OFF INDEPENDENTLY, THE SPEEDOMETER AND TEMPERATURE GAUGES SHOWED INACCURATE READINGS. THE VEHICLE WAS TAKEN TO THE DEALER, WHERE IT WAS DIAGNOSED WITH ELECTRICAL FAILURES ON THE COMPUTER SYSTEM. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 70,000.

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

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

MY SPEEDOMETER RECENTLY MALFUNCTIONED AT AROUND 77,000 MILES AND I BROUGHT IT TO THE ATTENTION OF THE DEALERSHIP'S SERVICE MANAGER, JEFF BEVINGTON, AT RALLY GMC AUTO GROUP IN PALMDALE, CA (WHERE I PURCHASED THE VEHICLE NEW IN 2005). I WAS GIVEN SERVICE BULLETIN #07187C - SPECIAL COVERAGE ADJUSTMENT INSTRUMENT PANEL CLUSTER GAUGE NEEDLE FUNCTION (MARCH 20, 2009), WHICH INDICATES THE FOLLOWING: THIS BULLETIN IS BEING REVISED TO INCLUDE CERTAIN 2005 MODEL YEAR VEHICLES IN THE U.S. ADDITIONALLY, FOR U.S. 2003-2005 MODEL YEAR VEHICLES, GM WILL PROVIDE THE INSTRUMENT PANEL CLUSTER (IPC) ONLY, AT NO CHARGE TO THE CUSTOMER FOR VERIFIED FAILURES BETWEEN 70,001 MILES (110,001 KM) AND 80,000 MILES (130,000 KM).

HOWEVER, JEFF BEVINGTON TOLD ME THAT SINCE MY VEHICLE IS OLDER THAN 7 YEARS AND OVER 70,000 MILES, IT IS NOT COVERED??? HE SUGGESTED I CALL THE GM TOLL FREE NUMBER (800) 222-1020 AND ASK IF THEY CAN HELP. I CALLED AND SPOKE TO DONTES WHO TOLD ME THAT GM HAS NO RECORD OF THE SERVICE BULLETIN MENTIONED ABOVE??? *TR

PROBLEMS TURNING IGNITION SWITCH BACK AND FORTH, AND ALL OTHER GENERAL MOTORS TRUCK THIS MODEL BOTH CHEVROLET AND GMC HAVE HAD SAME EVENT. FATHERS TRUCK IS 2007 CHEVROLET SUBURBAN HAS SAME PROBLEM. *TR

THE SPEEDOMETER READS FAULTY SPEEDS, AS MUCH AS 20 MPH OVER THE ACTUAL SPEED. *TR

MY VEHICLE WAS PARKED IN MY DRIVEWAY. I WAS WALKING DOWN THE DRIVEWAY AND THOUGHT THE CAR WAS BEING STOLEN AS IT WAS STARTING. THERE WAS NO ONE IN THE CAR. THE CAR DID START SEVERAL TIMES ON ITS OWN SO I DISCONNECTED THE BATTERY CABLE AND HAD IT SERVICED IMMEDIATELY. HOW LONG IT HAD BEEN DOING THIS I DO NOT KNOW. I DO KNOW IT HAD NOT BEEN DOING THIS ON THE PREVIOUS DAY AS I WALK BE THERE EVERY DAY AT LEAST 2 TIMES. *TR
