Selected complaints filed with NHTSA by 2006 GMC Envoy owners, lightly cleaned up (personal details are redacted by NHTSA).

Went to drive home at night lights were working then all the sudden went out. Pulled over checked fuses n restarted auto and still no lights, the dash board lights were out as well. Safety of other drivers and my family were affected. Did have to have a friend come and get us. And went to get auto next day n still no lights. When got home checked everything agine and fuses were ok the wireing look all intact. Still no lights. Or dash lights.

Had problems with the heater's blower motor not blowing or sometimes blowing but not on every speed. Looked up issue on youtube and found many videos of the same issue and the videos showed them having to replace the heater's blower motor resister. As the resister was being replaced, we noticed the resister was melted onto the plug it plugs into and the thick red wire was also melted. Resister got replaced and the blower speeds all worked again. Shortly after installation of the new resister, the number 5 speed failed but all others continued. Three months later, the resister failed. Exchanged and replaced the resister again and worked on all speeds but 5 again. Had a smell to it while in use, we got use to it and thought nothing of it anymore. …

I have a 2006 GMC Envoy denali that caught fire this morning, it was an electrical fire, caused in the HVAC blower circuit, the circuit fuse did not blow, the cabin filled with smoke, and an open flame was created. I managed to put the fire out, however someone else in this situation might not have even been able to pull off a busy highway, let alone extinguish the fire as it was under the dash behind the glovebox. The symptoms before the fire were as follows: 1)a faint burning electrics smell (electrical smoke is very distinctive) 2)blower quit running(within 30 seconds of smell) 3)cabin filled with smoke (within 1 minute of smell) to the point I could not see out the windshield 4)open flame was present under dash (within 2 minutes of smell) the vehicle was in motion, 50mph, heating system was running, outside temperature 5* fahrenheit. …

Tl* the contact owns a 2006 GMC Envoy. The contact stated that the motor in the driver's door shorted out and the window regulator and motor were burnt. As a result, the vehicle almost caught fire. Smoke appeared from the door panel, which the contact managed to put out. Coyle Chevrolet Buick GMC (1801 broadway st, clarksville, in 47129, [phone]) diagnosed that the vehicle needed a new power window switch, fuse, and harness. The repairs were completed by an independent mechanic. When the contact discovered that the vehicle was included in NHTSA campaign number: 13V248000 (electrical system, visibility), the manufacturer was called and advised that the vehicle be taken to the dealer for reimbursement. The dealer did not reimburse the contact and presented the repair paperwork to the manufacturer. …

Both daytime running lights and headlights and high beams cut off while driving. Was pulled over for defective equipment. Wires in passenger headlight melted, didnt check drivers side. There are recalls on the 06 Envoy headlights, but I was informed that it doesnt apply to my VIN. Even though I am can no longer drive at night due to vehicle defect

As I was driving down I-75 at 10:30 pm my headlights just randomly went off! I was driving approximately 70 MPH and I was in an area that had no lights alongside the road. I slammed on my brakes to attempt to move to the side of the road. After I slowed enough to move over, my headlights went back on. I was so shook up, I'm not sure if my rear lights went off as well. This type of incident happened again this past weekend and I had to pull to the side of the road and actually shut off the engine and re-start my car twice before my lights went back on.today, on my way to work, in the dark, just before I was pulling into our parking lot, they went off again. I also have noticed that when I press on the automatic window buttons, my lights dim and then brighten. Another issue is the dash light for the gas cap turns on and off randomly while driving the car. …

While servicing my vehicle at an authorized GM dealership, I was notified of the recent recall regarding headlamps which get hot and can fail. It has been nearly 8 months since that recall was issued, and yet there remains no identifiable remedy or solution as to how they will resolve the issue and repair / replace the defective components.. Entitled to safe vehicles, I am unsure as to how or why GM would believe that 8 months to not even have announced a solution is an absurdity. At this point, the period of time in which the manufacturer has had to develop and implement a solution is simply unacceptable as a consumer. I am under the belief that their solution to the problem is simple, they are going let the vehicles age a few more years and hope by that time, additional vehicles requiring repair will no longer be on the road and the issue will magically go away. …

I have had 2 problems with this vehicle. The first one was at 28000 miles, about 3 weeks after I bought the vehicle. The resistor for the heat/ac fan caught fire while I was driving at about 5 MPH in heavy traffic. The fire went out on it's own by the time I had room to pull over (about 15-20 seconds). I was unable to get the part replaced right away so I had to drive around in cold and icy conditions without even being able to run the defroster. The second problem was that at about 32000 miles my gas gauge broke. I had just filled the tank and was driving at about 65 on the highway. The gas gauge needle dropped to empty and stayed there. I made sure that I was not leaking gasoline and continued on my way. It worked intermittently for a while but is now completely broken. …
