Four problems related to instrument panel have been reported for the 2006 GMC Envoy. The most recently reported issues are listed below.
Fuel gauge is not working properly on my vehicle. It stays on "e" when there is plenty of gasoline in the car. There have been several complaints about this that I have seen on websites. Ocassionally the gauge willl move up but then go back to "e". I went to dealer and they said it is a bad fuel senor guage which is in the gasoline tank. Seems like this is a common issue and could cause other problems. The fuel gauge has been like that for over 6 months, as the cost was astronomical and I believe there should be a recall. Additionally, recently my oil pressure gauge has shown the max amount and then last night it went down to the lowest amount on the instrument panel. It goes back and forth from high to low and the oil pressure low light comes on the instrument panel and then goes off. It says to stop engine. There does not appear to be anything physically wrong with my engine and I will be taking it to the dealer tomorrow to confirm that. I believe both of these issues are caused by a faulty instrument panel or electrical system included in gm's models. I have a family member with an older GMC SUV with similar issues and they also had issues with a GMC truck they used to have but got rid of it, due to the malfunctions. Seems like a very common issue that should be resolved by ge.
Driving when three lights showed up on instrument panel stabilitrak, check engine and reduced engine power light came on the Envoy completely turned it self off. I waited a few minutes then started the car. It started the check engine light was the only light on. I got home and restarted car all lights disappeared. Next day driving the same thing happen. Three more times on the way to mechanic the Envoy turned itself off. Find out the programmable control module pcm was defective. This car was purchased as a certified used vehicle 07/08. I then find out the part is readily available and not a special order. They refurbish this part with a one year warranty. I can not believe that GMC would engineer a car to entirely shut down when driving this could have been very dangerous had I been on the freeway going 65 mph, also that this should not happen as it is not a wear and tear issue. The codes that showed up were apparently not covered by GMC. With this part being readily available I must not be the only one who has had this happen. This was a costly repair, and I feel that someone should look to see if this has happen to others, before someone gets hurt or killed.
Starting in December 2007 every time I fill my gas tank the sensor light comes on and stays on, after a few miles the check engine light comes on. The gas gauge reads empty, then it will read something else. So I have to always reset my mileage so that I know how far I have went. This GMC is only 2 years old. It drives me nuts with this problem. It will finally reset to where the light goes off and the check engine light will go off. For a couple of days then I have to fill it again. I almost dread going to put gas in.
The check engine light came on and followed shortly by the engine quitting, 1 time at idle, 2 times in while under way in traffic.
