#38 of 520 2005 GMC Envoy Problems
Jun 16, 2009 (5:05 am)
I have been experiencing problems with my 2005 GMC Envoy. The speedometer stopped working and reads 120 miles an hour no matter how fast I'm traveling. The gas indicator also stopped working and stays on "E" even with a full tank of gas. I also recently had to have the head gasket, fan clutch, water pump, and thermostat fixed at a costs of about $2500. This vehicle is too new of a model to be experiencing these severe problems. Has anyone experienced these problems?

I have been having problems with my speedometer for the past 6 months, off and on. I finally couldn't take it anymore and decided to check the internet to see if anyone else was having issues. I was shocked to find so many!!
I talked to GM today and their response was that Envoys were not covered under the special coverage. I was told to get a diagnostic run on my truck by a GM service shop and to have it fixed. Once that's complete I can then send in my paperwork and then they'll decide IF they want to pay for it or not!!! Has anyone actually had their claim paid?
I know there have been a few class action lawsuits filed because of this issue. Does anyone know of one in Texas? If not, is anyone interested in trying to create one?
I don't understand why GM will not fix the problem when they know what it stems from. It's wrong that we as consumers have to pay for any repairs out of our own pockets first when GM knows of the defect!

I hope this will help some of you for this problem, the speedometer on my Envoy some times started to work from 60,went back to 40 wen I park, and finely stop working at 120 even wen i turn the engine off, then I read from this forum about the stepper motors, so I did as he say, went to ebay and bought the stepper motors cost me $35.00 + sh & han, all 6 of them and follow the replacement instructions they sent me, it took me about an hour to replace the speedometer motor and re-install the cluster in to my car and now is working fine.

I also have a envoy with a speedometer issue. It says i'm doing 120 no matter how fast or slow i'm going. I have no other issues electrically no service engine or fuel guage problems. Could it possibly be a sensor or something?

I recently spent a bundle to replace my instrument cluster due to speedometer problems. I don't understand why GM won't stand behind this repair, when the same speedometers have been recalled on a number of other GM products. The best thing we all can do is to report our problems to the National Highway Transportation Safety Board -- they have a website that allows ready filing of complaints. If the feds get a sufficient number of complaints, they might actually act on our behalf.
Funny thing is, on all the GM vehicles I've owned, the old analog speedometers never failed. GM should be ashamed of the way they're treating Envoy owners -- don't know about anyone else, but I'll certainly think twice before buying another GM product.
#45 of 520 never again GMC Envoy
Oct 22, 2009 (8:31 am)
Mine started with the Service engine soon light on/off for about 6 months, took it in they told me it was the Crank to Cam system about $450-500.00. I told them forget it. Then I was told the Service Engine light was a faulty thermostat. Now my speedometer jerks and sometimes pegs out at 120 and stays there. My cruise control Works intermittenly this vehicle has been nothing but trouble. My mechanic calls it prosessed. If I start the car several times the speedometer drops back to 0. It only happens when I drive it over an hour or so.
Anyonw else had trouble with Cruise Control also?

Did you try to send them a message to the Transportation board? I will write a letter along with anyone else on these Envoy's. The only good thing I say about mine is the Stereo is Awsome. Now that will probably jinx.
#47 of 520 04 envoy water temp sensor location
Oct 29, 2009 (12:50 am)
I have an 04 envoy where the water temp sensor is intermittently according to the code reader. I purchased one from auto zone and went home to put it in. That was a couple of months ago and I've still not found the darn thing. Can't find schematics to locate it. Anybody know where the sensor is located?
