2004 GMC Envoy: adaptive cruise control problems

Filed May 17, 2018 · Acceleration · NM

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.

The speedometer and tachometer of the SUV began to indicate incorrect readings. The speedometer works fine until we go on the highway and travel with the cruise control set between 65-70. Then they will read the incorrect speed for a week or so then start working fine again. The tachometer needle just "hangs." I talked to 2 different repair shops who advised me that this is a common problem with envoy's and trailblazers. The cost to do this is over $500 or more. It appears that several other 2004 gmc envoy owners are experiencing this same problem. A recall should be in order. When I talked to the repair shops they said before they can correct the issue under my extended warranty is to see it happen. Each time I had an appt set it would start working before the appt date so there is nothing they can do. Very irritated that gmc doesn't address this now.

The instrument panel cluster on my gmc envoy 2004 is defective as it is on a multitude of other gm models between 2003 and 2005. One of the consequences is that the speedometer will not work or will report a faulty reading while operating the vehicle. This is an unsafe driving condition and for some reason gm has not yet issued a recall on this problem for gmc envoys of the year 2004 even though other years of this model and other models of gm vehicles have been recalled for this exact issue. Please help gm do the right thing by it's envoy owners. We have certainly bailed them out enough. There is another potentially deadly consequence of this issue. If one were to be driving the vehicle at 60mph using cruise control and the speedometer were to all of a sudden peg itself to 20mph, there would be a sudden and abrupt acceleration as the computer in the car attempted to regain 60mph even though the vehicle was already at that speed. Thank you for your time and attention to this dangerous speed control issue.. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Tl*the contact owns a 2004 gmc envoy. While driving 60 MPH with the cruise control activated, the contact passed out due to a severe medical issue . He lost control of the vehicle and crashed into a tree. Upon impact, both frontal air bags failed to deploy. The contact and passenger were severely injured. The driver sustained a broken clavicle and his teeth were knocked out of his mouth. The passenger sustained a laceration to the head and abdominal injuries. The vehicle was inspected by an insurance adjuster, who was unable to determine why the air bags did not deploy. The vehicle was destroyed. The contact called the manufacturer and was informed that an investigation was implemented and a representative will call him back in five business days. The failure mileage was 42,600.

My RPM gauge is not working. My speedometer works when using in stop and go mode or city driving. But when I am on a trip my speedometer will quit working accurately. It will reflect a much lower speed than I am going. My cruise control is often engaged when the speedometer stops working. But the RPM gauge no longer works at any time. I talked to someone at the chevrolet dealership and they said that the symptoms that I describe are very similar to the 2003/04 chevys that do have a recall. I have not taken any steps yet to fix. I was told that it would be $95 for a diagnostic service and that most likely it would cost $550 to fix (based on what they know about the chevys that are on recall).

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.

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.

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.
