Vehicle was being driving approximately at 55 MPH. Engine loss power, gas pedal lost resistance and went all the way down to the floor board. Vehicle was pulled over to the side of the road and engine was stalled and all the dash lights were flashing one and off. Engine started to have white smoke coming from under the hood. After a few minutes, the white smoke turned into black smoke and the engine caught on fire. Vehicle was engulfed in flames after a few minutes.

On-going issues with my 2004 gmc envoy since purchase. Leave home, travel to destination, usually a short distance, when trying to restart vehicle all dash lights come on, radio works, windows work, etc., turn the key to start and nothing happens, no attempt at starting what-so-ever. Makes no difference with temperature, time of day, rain/shine, etc. Often if you leave the vehicle to sit for an hour, it will restart, sometimes sooner, sometimes not at all. First incident happened when we had 308 km on the vehicle, now we have 68,000 km and problem still exists. They have changed the ignition switch numerous times, reprogrammed the settings for international vs domestic in regards to the apparent security system that I have, which we discovered has never worked either. Numerous issues with the ABS coming on with dry pavement. Water in rear backup lights, they were drained and re-sealed. Rust on all interior door panels, back door and hood where joints meet, repaired. Water on the floor at the door when it rains, fixed seal at door. Drivers side door locked when you left the vehicle without locking it myself, reprogrammed. Interior door trim/seal repeatedly falls off from back right passenger door. 10 months left on our lease....can't wait to find a new vehicle. Completely not satisfied with the vehicle or by the service we have received.

When key was turned in ignition all lights would work ,but engine would not turn over. Speedometer would jump to 70 MPH ,and tachometer would jump to approximately 2000 rpms even though engine was not running. Dealer diagnosed problem to be faulty ignition switch due to low voltage at position ignition one.

Headlights, interior lights, all lights on vehicle flicker while driving on the highway. The vehicle does this when there is no apparent load on the electrical system (I.e. Blower, defroster, AC, power seats, windows etc.) the lights become very dim and then bright again in the matter of a few seconds. This can be dangerous to vehicles in front of you and approaching as they believe they are getting "flashed" by your vehicle. It is very unnerving driving with this random occurrence.
