Cruise Control problems of the 2004 GMC Envoy

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.

The cruise control is intermittent.

2004 GMC Envoy xl speedometer and tachometer inaccurate readings. Speedometer readings some as high as 115-120. Have no idea the actual speed at which I am travelling. Terrified to think of using cruise control when travelling interstates many times each year. Have reviewed online comments and I am not the only person experiencing this problem. Gm/GMC appears to know about the problem based on the comments and dealer/service responses. Stands to reason that a faulty instrument panel could affect other functions of car. Not knowing speed at which I am travelling is dire safety issue. What has ntsha done to address this issue with gm/GMC?.

Car lurched forward and engine speeded up when pulling into my driveway at home. Most of my dashboard gauges have been failing over the last year including the speedometer. I was using the cruise control prior to the event. I think it may be related to the computer. I was able to stop the car by turning off the engine. The brakes would not stop the car. The dealer has advise me that they know about the instrument panel failing but no recall has been issued.

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.

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.

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. . Read more...

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.
