Six problems related to ignition switch have been reported for the 2004 GMC Envoy. The most recently reported issues are listed below.
Bought my 2004 GMC Envoy in may 2009. After about a month and a half of driving it, all dash gauges started working intermittently, and the warning bell would go off, and all warning lights started flashing. Shortly after that began, all gauges quit working all together every other time I would start the vehicle. Took the vehicle in for repair, they replaced ignition switch and half way home from the repair shop, it all started over again. Been doing it ever since.
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.
Upon attempting to start the vehicle, all the dash board warning lights and turn signal indicators came on and stayed on. All the gauges started acting erratically and all the needle indicators started jumping at random. When I turned off the vehicle and tried to start the vehicle again, the vehicle started without any problems. The very next time I tried to start the vehicle; it did the very same thing as mentioned above (gauges acting erratically, etc. ). I attempted to start the vehicle several more time each time with the same result. Finally the vehicle started and no further problems were experienced. I drove the vehicle for approximately 1200 mile over the next few days. Yesterday, I was driving home at a speed of approximately 35 mph when the vehicle suddenly and without warning quit. I coasted to a safe spot on the shoulder of the road. I tried multiple times to restart the vehicle. Each time the vehicle exhibited the same symptoms as mentioned above e. G. Gauges acting erratically. After about 5 min. The vehicle started normally and I was able to drive home. In my driveway I attempted to start the vehicle several time. Each time the vehicle exhibited the same symptoms as mentioned above e. G. Gauges acting erratically. Upon consulting with a local mechanic and a local dealer, I was informed the problem was most likely a bad ignition switch. The vehicle is currently having the switch replaced.
