Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I just bought a used 04 GMC Envoy with 30,000 miles on it. Now about a month after I bought it I'm having problems with the speedometer. Sometimes it works sometimes it doesn't. when it does not work it reads to high or two low. I can be driving down the road at 65 and it will drop below 0. or I can be stopped at a light and it shows 40. A quick search on the web shows thousands of people with the same problem. I feel GM and GMC should have to do a recall on this as it could be a life and safety item. For example one could slow to the recommend speed for a curve or a turn. If the speedometer is reading two low then the person would be traveling two fast for the turn. I see also where a class action law suit is in the works on this.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 37,500 miles
The problem was first noticed in November of 2006 when I received a speeding ticket, I was not speeding according to my speedometer. The dealership said my speedometer was working properly when in fact it was not. After another stop by police, I took the truck to different dealer and I was told the same thing. I was again stopped on 7/4/2007 for speeding. I removed the gauge cluster and sent it to specmo myself for testing and specmo found the speedometer defective; wire chaffing and servo motor intermittent shorting, they repaired it.

Vacation to yosemite, the tachometer gets stuck and gives the wrong reading, without any warning. It has been consistently giving me the wrong RPM ever since. I have done nothing to correct the problem.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 57,568 miles
Speedometer stared moving up and down with the speed of the vehicle but would have a jerky movement now the speedometer no longer resets to zero. At a full stop the speedometer will read from 40 to 70 mph and at speeds a low as 40 mph the speedometer will report speeds up to a 120 mph. This problem does not all the driver to accurately judge the speed of the vehicle. As of this complaint I have not fixed the problem but all indications from other people is that the instrument cluster will have to be replaced or reconditioned.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 55,000 miles
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: 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 NHTSA will be able to help me and the other hundreds or thousands of consumers with this safety issue. Thank you for your time.
