Speedometer started acting inconsistent and then "fixed" itself the last week of December 2009. At that time it would not drop below 20mph. After seemingly being ok, the first week of Jan. 2010, the speedometer jumped to 80mph and hung there and pegged out at 120mph when driven. I made appt. With gmac in winston salem, nc and was told the entire instrument cluster would have to be replaced @ $600+. panel has been ordered and to be installed end of week. Now I see that there has been a letter sent out by gmac that I never received, to replace this cluster if less than 70,000 miles. I now have a little less than 73,000 miles. Apparently this has been a major problem"?"

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 ipc problem for GMC Envoy 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. Matt dye

My vehicle's instrument cluster fails on a regular basis after checking into the situation with GM dealers there is a recall on the Sierra's and Yukon which have the same cluster as my vehicle but GM refuses to stand behind the defect on the Envoy. Parts have not been replaced yet on my vehicle hoping that GM will wake up and realize this is a common problem on the Envoy and that it requires attention. The issue occurs on a regular basis normally several times per month, after a few days the cluster will reset and work as normal but has been very frustrating to deal with. When problem occurs I have to use my gps Navigator to tell what speed I am traveling. The cost of the replacement is approx. $650.

Faulty speedometer in 2004 GMC Envoy, bad steeper motors in all 6 gauges. Speedometer inaccurate, will go past 120mph, will affect tach eventually, all gauges will go bad. The problem is faulty steeper motors GM was supplied these by delphi electronics. GM won a class action suit, why no relief to Envoy owners" this affects all 2003-2004 Envoy, they were included in the original service bulletin then removed" why no recall on these items GM is aware of this but as of today no action has been taken.

An independent mechanic stated that he could rebuild the transmission. The vehicle has not been repaired. The failure mileage was 44,386 updated 07/28/09 the transmission failed at 58,000 miles.

My 2004 GMC Envoy speedometer stopped working properly. There was no fore-warning. If I'm on the highway going 60 mph, it reads I'm goin 25 mph. The needle falls below "0" when idling. I've called a GMC dealer and they said there is no recall for this although I've read many exact complaints online.

- Rockland, MA, USA

I own a 2004 GMC Envoy and the speedometer has stopped working correctly. It is very erratic and goes anywhere between 10-100 miles over the speed I am traveling. I've been stopped twice for speeding and received a fine for $170. Gms states it is not a safety issue, I disagree! when I was stopped I tried explaining to the police officer what was wrong, however he didn't want to her it.

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 Chevy 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 Chevy that are on recall).

Speedometer does not work at times. Sometimes it will just stay at "0", others it will be at various speeds even while in park.

Speedometer quit working on my 2006 GMC Envoy.

- Afton, WY, USA

The tachometer would quit working but it happened only a couple of times in Jan 2008 & again in June 2008 and when we turned the car off and started it the next time it seemed to be fine as if it needed reset. In Jan of 2009 the speedometer began to fail at first occasionally then all the time at the same time the tachometer sporadically failed. So we took it to the dealership and had them replace the instrument cluster in the dash (they kept the old part) and GM refused to help with the problem sitting the mileage on the vehicle at the time of the repair.

The speedometer has a malfunction that will make the speedometer read very erratic, at a steady speed the speedometer has been all the way over to the 120 mph and on other days it will stay a zero. This problem occurs frequently, not everyday but I would say atleast once every 2 weeks. I believe there could be grave consequences., you have absolutely no idea how fast or slow you are actually going, especially if there are no cars traveling the same direction as you. I will attempt to repair this item myself since the dealer says it can cost $300-$700 to fix.

Ltr from senator cardin on behalf of constituent re problems with his 2004 GMC Envoy. The speedometer and tachometer stopped working. The consumer stated it was impossible to determine the speed he was traveling.

- Cumberland, MD, USA

Speedometer failed. At first it did not correctly reflect vehicle speed, then fluctuated rapidly over the course of several days, and finally failed completely.

- Springfield, VA, USA

Speedometer on my 2004 gmv Envoy behaves erratically and does not work. When starting up auto speedometer could be at zero or up to 100 or continues to not function at all. Needless to say I have no ideal at exactly what speed I am traveling. I have read on the web that many others have this same complaint. I would think this should be a "safety issue" and should be reason for a recall.
