My 2004 gmc envoy has developed an erratic speedometer. The speedometer reflects inaccurate speeds causing an unsafe driving condition. I contacted my local gmc dealer who researched to find no recall concerning this problem I then submitted my complaint to the bbb hotline and was rebuffed their also. I have consequently done additional research and have found that gm has issued a special coverage adjustment bulletin for 2003-2004 cadillac escalade, chevrolet avalanche, silverado, suburban and tahoe, gmc sierra and yukons. The speedometer unit in these models are very similar in both appearance and are manufactured by the same supplier gm uses. The adjust bulletin is #07187 dated september 28,2007 and covers the condition for a period of 7 years or 70,000 miles regardless of ownership. After visiting many gmc and chevrolet chat rooms it is readily apparent that this problem is very common and will eventually result in a fatal accident. I am requesting that the federal safety agency formally investigate this problem before this happens.

Speedometer quit working on my 2006 gmc envoy.
Problem started out as erratic reading with speedometer. After approx. 5 days speedo finally wouldn't register at all took vehicle to authorized dealer to be repaired - $555.00 charge to replace instrument panel and reprogram. Called gm for financial help as I noticed there were alot of failures with gmc SUV's and pick-up trucks. Gm would not acknowledge there was a problem which I feel is totally disingenuous. Speedometer is necessary to be working as a safety issue. Because I was out of state at the time of part breakdown I felt I had no choice but to have problem fixed before my return trip home (1250 miles). Judging how many other envoys have had same problem, I feel gm is dodging their responsibility I noticed that there has been class-actions against them for the same problem.
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 gradually decreased from interstate speed (70mph) to 0 MPH while driving. Speedometer fails to operate. I personally know 2 people who have had this happen on a 2004 envoy.
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.
The tach on my '04 envoy with 67k miles started acting erratic and has completely failed just as all the other service bulletins . This has corrected itself buis till erratic. Gm needs to address the faulty electronic gauges on these '04 envoys.
Ltr from senator cardin on behalf of constituent re problems with his 2004 gmc envoy. *nj the speedometer and tachometer stopped working. The consumer stated it was impossible to determine the speed he was traveling.
Instrument cluster. Speed odometer and tach not accurate. I have had 2 speeding tickets because I don't know how fast I am going. Not sure of the date it first happened but it is getting worse. Gm dealer in my area was rude to my wife and said they will not cover it.
I began experiencing problems with the instrument panel on my 2004 gmc envoy a few months ago. The entire panel would go out and all the gauges bottomed out. I could not tell my speed, gas level, rpms, etc. The panel would stay out for a few days then return to normal. Also on occasion the speedometer would stick at 60 MPH and only correct itself if I pulled over and turned the truck off then back on. Finally, about two weeks ago the entire instrument panel went out and has never come back on. I have dropped it off at the dealership for service and am awaiting their response. This problem has caused me to run out of gas twice because I was unable to judge my fuel level. Luckily both times I was in an area with easy access to the shoulder of the road. I currently have approximately 55,000 miles on my truck. (I can't be sure of this, however, since the odometer is a part of the panel that is out.) this is a serious and, according to my research, recurring problem the gmc should be forced to correct and pay for.
Speedometer failed. At first it did not correctly reflect vehicle speed, then fluctuated rapidly over the course of several days, and finally failed completely.
Tl*the contact owns a 2004 gmc envoy. While drving 20 MPH the speedometer stopped working. The dealer stated that they assumed it was a part of the manufacturers recall and repaired the vehicle. The dealer confirmed after the repairs were made that the vehcle was not within the recall VIN range. The dealer has billed the contact for the repairs. The failure mileage was 52,000 and the current mileage was 55,000.
Speedometer malfuctions.
I have a 2004 gmc envoy in which the speedometer has stopped working. I researched this on the internet and it is a common occurrence. I almost caused a wreck because the speedometer said I was going faster than I really was and the cars behind me almost ran into me. This is a safety issue that I feel should be investigated. Could you please assist w any recall measures. It costs over 500.00 to replace this.
My 2004 gmc envoy MPH and RPM gauges are not working properly, I called the dealership and an extended warranty was put on all gmc/chevy trucks and SUV for the dashboard cluster except for the envoy, any newer models. The part is at least 500 and advised can only be done by dealership due to programming. Im furious, my truck is only at about 53,000 miles. This defect needs to be under recall for the envoy asap!
This past month the speedometer set at 40 MPH with car in "park" position. Afterward when driving, my actual speed had 40mph added to the reading. This has occurred three times so far in october 2008.
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.
Speedometer stopped working.
Driving at slow speed and noticed speedometer was reading incorrectly--much higher than actual. Vehicle driven several times since, with continued incorrect speed rating. All original equipment at 68,000 miles with no previous repair noted.
Speedometer quit working properly on friday, july 11. By monday morning, it was back to normal.
Speedometer stopped working.
My speedometer gets stuck and does not function at times. Although no harm has been caused, it is a concern that I've seen many others file complaints on.
The speedometer on my 2004 gmc envoy does not work properly. It will sometimes show that the vehicle is going a certain MPH while the vehicle is in park. Example: vehicle is in park. Speedometer shows 34 MPH. When driving, the speedometer bases it's speed off of 34 MPH being at 0 and actual speed is 34mph higher than what I am actually going. Also, vehicle speedometer will sometimes get stuck past 120mph because of the needle being at a certain speed when the vehicle is not even moving.
The fuel gauge on my 2004 gmc envoy is not working.
The MPH and RPM gauges not working. Needle would not go down to zero. Would get stuck in one MPH and continue to increase from there. Was able to get it down to zero in 5mph increments by starting and shutting down the engine, but then after driving it would stick at 40 and up. Thought it was strange that my other 2004 chevy truck received a recall letter for the exact problem my gmc was having. Had to pay out of pocket to replace dash board cluster(over $500.00). I needed to know the speed I was driving. Very dangerous situation.
The speedometer and tachometer are not working and the check engine light is coming on.
Tl*the contact owns a 2004 gmc envoy. While driving 40 MPH, the speedometer sporadically failed and displayed inaccurate readings. The contact is in the process of having the vehicle inspected. He called the manufacturer and is awaiting their response. The powertrain was unknown. The failure and current mileages were 26,500.
Speedometer reads erratically.
Speedometer has stopped working properly. Most of the time it is stuck above 120 MPH. It never shows the correct speed the vehicle is going.
I own a 2004 gmc envoy and I like others have a speedometer that has failed also....and the tachometer has also failed...sometimes the speedometer shows the speed but it is not the correct one...as I was on the freeway and it showed I was going 10mph....other times it just sits on 0....
