GMC Envoy adaptive cruise 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).

Check engine light accompanied by engine cut-off when cold weather since november 2009. Twice gmc dealership couldn't duplicate issue and no idea for check engine light. New development of fuel gauge failure each time of gas fill-up accompanied by fluctuating fuel level indicator. Clicking noise coming from gas pedal for 3 years with increasing frequency. Electrical system including gauges, speedometer, power steering noise, cruise control seem to be having issues. Dealership claims no recalls, but electrical issues appear to be common according to edmunds.com forums for gmc envoys.

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.

Vehicle has had numerous electrical problems. Mirrors won't adjust, seat won't adjust, radio doesn't work, service engine light comes on, service air bag light comes on, car stalls at traffic lights, cruise control won't work unless I turn off engine and restart. Vehicle was serviced by one dealer who could not find anything wrong. Second dealer could only find air bag module burned up and charged $1500 to replace.

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).
