Verbatim from NHTSA complaints, newest first
“The contact owns a 2004 GMC Envoy. The contact stated that while the vehicle was parked and unoccupied, the contact noticed that the front passenger's door was on fire. The contact stated that he arrived home just in time and noticed the fire. The contact stated that, because it was raining, the contact's wife had powered the window up; however, the contact noticed that the window was down when the fire occurred. In addition, the contact stated that the fire was blazing, and after the fire was extinguished, the smoke was still visible. The contact extinguished the fire. The contact disconnected the battery. In addition, the contact stated that it could have been a huge fire because the fuel tank had just been refilled prior to the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 133,295.”
“Headlight's,taillight's,turn signals stop working whenever they want.It's pretty scary to lose your headlight's when your driving at night.There's nothing i can do about it,except to sit wherever it happend and wait for them to come back on.My wife was following me one day and told me my brakelight's and turn signal stopped working and started to work again,she said this happened a couple time's at the same red light.There a couple of thing's (electrical)inside the vehicle that don't work anymore but i really dont care about them.To get the odometer to work i have to knock pretty hard on the plastic cover that cover's the instrument cluster,sometimes it stay's on,most of the time it wont stay on.The DIC (driver control center) doesn't work anymore.I cant even get to it.The speakers on the left side of the vehicle dont work anymore.I thought i would tell you about the inside also because it could be part of the problem.All of this happened when i was driving home from my daughter's two night's ago.I bought this vehicle about three or four's year's ago,and i had no problem's with it untill the other night.The person i bought it from is a good friend of mine.He…”

“MY DASH PANEL GAUGES BEGAN FAILING ONE BY ONE. MY HEADLIGHTS WILL SOMETIMES NOT COME ON AFTER STARTING THE CAR WITH THE HEADLIGHT SWITCH ON AUTO. A FLICK OF THE HEADLIGHT SWITCH IN AND OFF, DOES NOT MAKE THE HEADLIGHTS COME ON. SOMETIMES THEY COME ON AFTER DRIVING AROUND, AND THEN WILL GO OFF WITHOUT TOUCHING THE SWITCH. NOW, MY SIDE BRAKELIGHTS WILL NOT OPERATE CORRECTLY WHEN THE BRAKE PEDAL IS PRESSED. ONLY THE THIRD BRAKE LIGHT ILLUMINATES.”
