I was driving on the highway with the cruise control on. When I tapped the brakes to turn off cruise control, my speedometer was stuck at my cruise control speed of 65. My vehicle came to a complete stop and my speedometer backed off to 45 MPH, but would not return to zero. After stopping, then turning onto another highway, my speedometer was still stuck at 45 MPH. My cruise control was previously set at the speed limit for the highway at 65 MPH and I hit the button to resume cruise control. When I reached my destination, I turned my vehicle off, thinking it would reset to zero without power; yet, it is still stuck at 45 MPH and my car is off and parked in my driveway.
2004 GMC Envoy acceleration complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
I was driving in town and my speedometer stopped working at 0. The oil gauge is not working, pegged out at the max and my engine light is now constantly on. These events, particularly the speedometer not working, is a major safety hazard. Not driving at controllable speeds can lead to an accident and death. The parts and labor to fix this problem is $550. While researching this problem on the internet, I've found out that this is a common problem with gmc's in this year. There should be a recall with the cluster unit on 2004 gmc envoys. Gmc should try to prevent deaths that their products may create.
I purchased a 2004 gmc envoy with approximately 50000 miles on it in may of 2006. About 4 months later, the speedometer started acting slightly erratic, reporting speeds varying by 10-20 MPH (I.e. On the highway, keeping up with traffic at 65 MPH, the speedometer would report 45 MPH or sometimes 80 MPH. Over the past few weeks, the problem has gotten much worse, with the speedometer reporting 120 MPH at highways speeds, and 50 MPH at a stop, sometimes not registering any speed at all (o MPH). The cruise control has also stopped working, which I am assuming is related to the speedometer malfunction. I searched online, and apparently there are many other gmc owners with the same exact problem. Please see link below: http://www.topix.net/forum/autos/chevrolet-tahoe/t2bgkbgi55eknu77c/p1 this is the first gmc car I have purchased and I am dissatisfied with this safety issue. I am a pretty good guess at how fast I am going, however without an accurate speedometer I feel I am taking unnecessary chances. As a realtor, I often have clients in my vehicle and I am concerned for their safety as well. I filed a complaint with gmc, but I was referred to the dealer as there are no current recalls for this problem. The dealer says that this is a $500 fix, and I am concerned as this appears to be a manufacturer defect, based on the number of other consumers with this same issue. I never expected to have an issue this problematic with a vehicle 2 years old. I hope that by reporting this issue, the federal safety agency will be able to help me and the other hundreds or thousands of consumers with this safety issue. Thank you for your time.
Dt*: the contact stated while exiting the off-ramp of the highway at 20-25mph, the check engine and reduced power light illuminated and there was a loss of all vehicle power. Although the engine restarted after several attempts, the vehicle was towed to the dealer for inspection. The dealer determined the accelerator sensor needed to be replaced. Afterwards, the loss of power persisted and the accelerator sensor was again replaced by the dealer as well as the computer. Additionally, the horn intermittently worked, but the horn was not inspected.
Dt: contact stated the accelerator pedal had to be replaced. While accelerating to make a left-hand turn the accelerator would not take. The service dealer replaced the accelerator pedal. The repair was covered under the warranty of the vehicle. This remedied the problem. *ak updated 11/29/05.
I purchased a 20054 gmc envoy in february and we took our first long distance trip this summer. At interstate speeds on downhill slopes the cruise control bucks continuously, which I consider potentially dangerous. The local dealer told me that this was inherent in the design of the vehicle, and that many others did this also. I have never encountered this with other vehicles that I have owned.
