2004 GMC Envoy Owner Comments

problem #13

  • miles


My Envoy's cruise control will not engage at any speed above 60 mph. When the cruise control button is pressed the cruise control light will come on and go off again, without engaging the cruise control setting. However, at anything 55 and under the cruise control will engage fine. Also my 4X4 will not work either.

Speedometer flucuates past 120 and sometimes drops past 0 while driving. The fuel gauge will show full even when it's not.

After driving vehicle tends to lunge forward even after brakes are stepped on or after parked at a red light, in the first case driving at highway speeds, the speedometer freezes and hangs, during this occurrence we do not know what speed limit we are going which is scary and a safety concern especially with children in the car, to troubleshoot the problem and bring speedometer down to zero mph, the car would need to be turned on and off numerous times to set back to zero

Envoy 4WD 8-cyl

Speedometer is completely disabled, RPM and battery guages inoperable and gas guage sometimes does not work. I understand there was a recall but I did not receive any notification and now I am told it will cost between $400 and $500 to repair.

Envoy 6-cyl

  • 46,000 miles
Right after purchasing. Engine light has been on. Purchased in June/2006, with 40,000miles. 1yr after the RPM gauge quit working, right afterwards, the fuel gauge started messing up, going back & forth, then went out completely, battery/oil gauges are out now. The seat belt lights/airbag lights bing constantly & does not tighten up when put on brakes. When this happens the check gauges light comes on, and at the same time I have difficulty getting it in gear. I am also having trouble setting my cruise control.

The contact owns a 2004 GMC Envoy. When attempting to accelerate, the vehicle hesitates abnormally. The contact took the vehicle to the dealer, but they could not duplicate the failure and provide a remedy. The failure and current mileages were 75,000. Updated 06/03/09 updated 06/04/09.

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.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 64,000 miles


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 Envoy. GMC should try to prevent deaths that their products may create.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 55,000 miles
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: 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 NHTSA will be able to help me and the other hundreds or thousands of consumers with this safety issue. Thank you for your time.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 34,000 miles
: 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.
