Reduced engine power and engine light. Have had just about everything replaced I have my repair bills. Truck will run fine after being in shop then starts all over again. Throttle body has been replaced twice. It will drop me down to 20mph on the highway and I am afraid it is going to cause a bad wreck. It happened to me today and I am out of town I have drove 600 miles with a horse trailer to pick up a rescue horse and am afraid to start home with no clue what is wrong with this truck when I reset the battery it will work fine but I am telling you that it is going to cause a bad wreck. I don't mind paying for it just tell what the hell is wrong so I can get it fixed probably before someone gets hurt or killed.

My truck exhibited the same issues as #10240: Special coverage adjustment-heating, ventilation, and air conditioning blower not fully functional or inoperative - (May 9, 2011). However my auto climate fan was not covered. I believe this is a recall issue. My truck became smoky from the overheating wires and the HVAC system would run after cutting off the ignition.

- Rocky Mount, NC, USA

The truck was purchased with 113,000 miles on it and no apparent problems when bought. After about 3 months of ownership, the "service airbag" message appeared intermittently for the next few weeks. After that time, the message was constant on. Took the truck to my local dealer who charged to "repair" it. Message came back after about a week of driving. Message now reappears at random intervals. Don't know if the problem is with the airbag sensors, the control unit, or any peripheral switches. Dealer is incompetent and do not trust to fix the problem. Already paid good money to have this problem repaired and am not going to continue to pay for incompetence. Message appears when vehicle is in motion and when vehicle is started at random. Message will sometimes disappear for weeks at a time, then, reappear at random.

2006 GMC Sierra quit running on a trip we were taking. It started missing and eventually wouldn't restart. The truck has 82K on it and is very well maintained. The engine would turn over but not start... no spark? it has been to various service mechanics as well as my attempt to figure out what is wrong with it. Many new parts have been used: Icm, crank sensor, cam sensor, coil... no difference. This vehicle quitting on a very busy highway could have caused significant injury to myself and/or my passenger. When the truck was new it had an intermittent miss and while still under warranty I returned to the dealer. There they were unable to find anything that would cause the problem. This same miss was periodically present up until the time it quit running altogether.

My fan high speed burst out and I had a strong else trial burning smell. I had my truck looked at to find that my wiring harness and resistor had burnt. I had them replaced this last September. Since then I have had to replace two more resistors and one more wiring harness. I talked to two dealerships and no one told me about the, "special warranty adjustment". I had to research the internet to find this out. When I took my truck back to the original dealer, they blamed me for not knowing the language. I am glad I did not burn my truck up like several other had (found on the internet). Now the dealer tells me that main controller has failed and I have to pay over $400 in repairs. How do I know that the main controller did not burn out the resistor or wiring harness? I am concerned that large corporations are playing with our lives.

I have had to replace the tail light lenses several times because the tab that secures the lenses to the vehicle breaks and the result is lights just hanging on the truck by the electrical cords. I have the same problem involving my other vehicles in the past made by GMC namely a second family GMC Sierra that was made in the year 2004, and a Chevrolet Silverado. The electrical lighting on the dashboard has been malfunctioning for a long time. I noticed the malfunction during the first year I bought the truck. I have had to replace electrical switch in the air conditioning/heating the mechanic told me that the wiring is heating up and causing the short to the switch. The new switch has shorted out just like he said it would. I have a notification that my airbag needs servicing. There has been no accident involved to cause this issue. I bought this vehicle new and have been the primary driver since 2006 when I bought the vehicle.

Loss of fan - blower motor (HVAC) high speed operation failure. With loss of high speed fan, other fan speeds (lower) operation became intermittent, works after jiggling blower motor wire bundle at connection point on blower motor resistor. Visual inspection shows melted wire harness connector at blower motor resistor, unable to separate (remove) the connector. Searched NHTSA ODI database and found three very related defect complaints - inop fan, smoke and melted wires, fan loss. Fan failure could lead to fire from melted electrical connections, loss of visibility due to windshield icing in winter, fogging over when driving in changing weather. Windshield defroster requires operative fan and defroster is a required safety item. Dealer replaced blower motor electrical connector, wire harness, and fuse, charging parts to warranty and me for the labor. This appears to be a very common defect in this product line. There is a technical service bulletin for the repair including replacement of the connection wiring to insure any melted insulation is removed. This should be a safety recall. Dealer has old parts.

This complaint is about an electrical short in the wiring and plug going to the fan motor on the inside cab of my 2006 GMC truck. This truck has 43000 miles on it and carried it in to be fixed and was told nothing could be done because it was out of warranty. I'm very disappointed because I feel that this is a hazard. This plug has been going bad for some time now because I could smell the odor in the truck but could not pinpoint where it was coming from. After the fan motor stopped working I traced the problem down to the plug and found where it had been melting away. This is when I drove it back to the dealership and was told nothing could be done because it was out of warranty. I feel this should be a defect and not something that should be a warranty issue. This plug got very hot for a long period of time and melted it could have started a fire.

: the contact stated the speedometer displayed an incorrect reading up to 10 mph more than the driven speed. The vehicle was seen by a dealer, who determined this was due to the oversized tires on the vehicle which affected the overall telemetry. The vehicle was sent to an independent repair shop and an after market hyper-tech computer chip was installed to override the computerized telemetry of the vehicle. Updated 05/30/06.
