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.

2006 GMC Envoy Owner Comments

problem #12

Jun 052011


  • 81,000 miles


The contact owns a 2006 GMC Envoy. While driving approximately 65 mph, the contact noticed that the fuel gauge displayed an inaccurate fuel level reading. The vehicle then suddenly stalled due to the lack of fuel present in the fuel tank. The roadside assistance dispensed the required fuel into the fuel tank and the vehicle resumed as normal. The vehicle was taken to an authorized dealer, who stated that the fuel tank sensor was faulty. The vehicle was not repaired. The manufacturer was made aware of the failure. There was an open investigation under NHTSA action number DP10001 which closed and a preliminary evaluation had been opened. The approximate failure was 81,000.

Vehicle fuel gauge shows empty after filling fuel tank. After driving 30-50 miles, fuel gage appears normal. This started about 30 days ago. More recently, however, fuel gauge is inconsistent even after the 30+ miles. Some times it shows full, one half. I must refuel vehicle more often to be sure there is fuel in the tank.

Fuel gauge is inaccurate. Reads completely empty then moves up and down while driving around town. I never know how much gas I really have in it.

  • 80,000 miles
I have a 2006 GMC Envoy which has a faulty gas gauge. When I fill up my gas tank, the gas gauge shows the tank as being "empty" with the orange light on indicating an empty tank. As some fuel burns off the top (after approximately 20-25 miles), the gas gauge then moves to the "full┐ end of the gauge. While driving, the gas gauge continuously shows that it has more fuel in the tank than it actually does. Because I was concerned that the gas gauge was inaccurate and would result in running out of gas, I started resetting my odometer and tracking mileage after each fill up. Based on the mileage tracked thus far, I estimate the gas gauge to show that it has approximately 1/4 ┐ 1/3 more gas than what is in the tank.

Fuel gauge is erratic causing the driver not to know when the level may be dangerously low and leave him/her stranded. Gauge will register "empty" when the tank is full. The 'check engine" light sometimes comes on after 50-100 miles the gauge will register "full". it may or may not begin to read some level after that. The check engine light will go off. This is the second GMC vehicle I have owned to have this problem.

Envoy 6-cyl

  • 33,000 miles


Beginning in 2009 my 2006 GMC Envoy began having problems with the fuel tank sensor. It would show empty when in fact it was full. Now the problem is continuous. I must use to odometer to guess when I need to refuel the vehicle. I do not know when I may run out of gas. If this happens in a high traffic area if would definitely cause a safety hazard to myself and to other drivers.

GM Envoy 2006 fuel level gauge has been failing on thousands of cars for years and I am having the same issue. The Envoy and trailblazers gauge drops to empty, then bounce between fuel and empty then is stays on E until the repair is made. This has caused my wife to run out of gas in the middle of a busy highway and almost causing a major accident. GM dealerships says they have been aware of the problem for years and there is no recall and owners must pay GM $800 to repair this known issue that I find have been going on since 2005. GM refuses to recall the fuel sensor and says they will only repair if under warranty for free. The labor is $670 part bring the repair to $800+. if this issue is searched online you will find thousands of complaints and the fear of this causing a major accident if it has not already occured. This major issue needs to be recalled and corrected at GM's expense.

  • 50,000 miles
A few months after I purchased my 2006 GMC Envoy, my gas gauge started to act crazy. I took it into a repair shop and they told me it was going to cost around $800 to fix because they had to drop the tank. Since my car was out of warranty I could not afford to fix it. After some internet searching I noticed that hundreds of people have had the same issue with their GM product. Now my check engine light keeps turning on and I can't pass my emissions inspection to renew my plates until it is fixed. I have been keeping track of my gas via tracking my mileage, but have run out on a busy street. It is very expensive to fix and unsafe to keep in the condition it is in.

I own a 2006 GMC Envoy, in 2007 the fuel sensor stopped working at approximately 20K miles, so I couldn't tell how much gas I had, when full it registers as empty, it was supposedly fixed and then the fuel line came apart while I was driving. Now I am once again having the same issue with the fuel sensor, the vehicle now has 80K miles. I have contacted GM, but they are of no help. Upon checking the message boards there are thousands of Envoy & trailblazers with the same issue.

It seems that my vehicles fuel sending unit is defective after only 47,000 miles and through further investigation I found there are many other owners of this line of vehicles that are experiencing this identical problem. I have been told that it will cost over $800 to repair this with no guarantee that it won't happen again. I think this problem should be recalled as most owners of this vehicle are quite upset that they have to pay out of pocket for this defective part to be replaced.
