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.

2006 gmc sierra 1500. Consumer writes in regards to a letter received from gmc regarding an heating issue with the vehicle *tgw the consumer stated the problem seems serious enough to warrant a recall, rather than waiting for the problem to occur.

2006 gmc sierra c1500. Consumer writes in regards to resistor and connector wiring replacement.
Blower motor wiring harness wires melted and started smoking on my 2006 gmc sierra.
Tl*the contact owns a 2005 gmc sierra 1500. While attempting to use the air conditioner the contact noticed that no air would blow out of the vents. The contact examined the vehicle and stated that the resistor failed. The failure was not diagnosed and there were no prior warnings. The current and failure mileages were 130000.
The blower motor resistor overheated and melted the wiring harness,almost caused a fire,burnt my fingers trying to stop it from starting to burn,my 7 year old was with me.
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 the federal safety agency 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.
Dt*: 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.
