Truck service engine light has continuously come on and off. The transmission went and lost all gears at 52,000 miles, after the vehicle had been in at 31,000 miles for the same reason. There have been multiple items in which the service engine light has been on: Transmission several times but dealership could not find anything, fuel cap, fuel tank neck, internal gauge for the fuel tank, and only to get the vehicle back on 3/19/08 and for the service engine light to come on again. I swear this truck is a total lemon! I have had nothing but problems with this vehicle, and every time I have taken it to the dealership they can never find anything wrong. This last time was a total fight with the dealership regarding the transmission, along with no morals and respect for the consumer from GM themselves or the dealership. I believe that I have ended up with a lemon, and there is not a darn thing I have been able to do about it because no one seems to think that there is a problem. Contacted on-star to run diagnostic checks every time the service engine light has come on and they can not seem to find anything so I end up taking it to the dealer for $65 an hour for diagnostic check and being told there is something else wrong with the truck and was assured that they ran all diagnostic checks and cleared all the codes after fixing the transmission. This is beginning to become very annoying, costly, and unreliable when transporting children in what I call an unsafe vehicle. I have put more money into this vehicle than what it is worth with such low miles!

While driving and approaching a stop for a red light, there was a very loud crashing sound from under the vehicle. The vehicle was no longer able to drive in 1st gear or reverse. The vehicle was able to propel itself in 'd', but was very sluggish as if trying to start driving a manual transmission in 2nd or 3rd gear. While the vehicle was in neutral it would still propel itself when the accelerator was depressed. It was no longer able to be moved manually by pushing, it would only move when driven forward or when the rear wheels where lifted off the ground when it was towed. The dealer has recommended a new transmission.

There is an issue with either the transfer case or transmission of my 2004 GMC Envoy XL. On several occasions, while performing slow maneuvers (20 mph or less) in and out of parking spaces or making slower right or left hand turns, the vehicle feels as if it is being held back by something, until a loud clunk is heard as if a gear disengages, and then the vehicle jumps forward. This has proven to be dangerous to me, as I have felt more than once like I hit something. The vehicle also experiences very hard downshift, into first gear as the vehicle comes to a stop. This issue first appeared on the vehicle in December 2004, and has continued intermittently through the current date date (for more than 5 separate instances).

When I first bought the vehicle the transmission was shifting eratiecly for a while. I took vehicle to dealer, and they said nothing was wrong drive it until it breaks. 3 months and about 3,000 miles later I had not had another problem. Until I pulled up to a stop sign at a busy intersection. I checked for trafic and went to pull out except that the Envoy would barely move. It was like the brakes were on or something was holding the vehicle back from moving. The cross traffic was quickly approaching and I had no choice but to slam on my brakes and hope the other person didnt hit me as I was sticking out in the intersection. The other person swerved and missed me. I pushed down on the accelerator again and slowly rolled through the intersection. I stopped on the other side of the intersection and tried to start again. The same result of no acceleration as the car slowly began rolling and continued to accelerate to a normal speed but at much higher RPM. I took it to the dealer and they said that is was stuck in second gear. Park and reverse also worked but none of the other forward gears worked manual shifting the transmission or setting at any other drive position. They said they fixed it because of a service bulltin put out by GM. They told me they fixed a wiring harness, replaced the ignition switch and cleared all the codes.

I own a 2004 Envoy XL with a V-8 motor. I have complained to the dealer, who states they can't find a problem, that the transmission jerks extremely bad when it changes into 2nd gear and then again when it shifts into drive. I have been told by other Envoy owners that they have actually had their transmissions replaced, and one friend had even had his vehicle exchanged under the lemon law. The dealer had virtually done nothing to correct the problem. Other dealers in my area don't want to mess with the vehicle, and it only has 6500 miles on it. I'm beginning to believe that I've been stuck with a lemon.
