Ignition switch failure at speed causing loss of power to fuel pump which ultimately meant loss of power to vehicle at freeway speeds. Was told by gm that there is no recall on this particular ignition switch at this time.

My fuel gauge stopped working over a year ago and I do not have the funds to repair it. The engine repair light is continuously lit and I have run out of gas on a major interstate. This as a major safety issue for a woman in today's society( kidnapping, rape, runover by another vehicle) I have learned to fill up every 3 days regardless of miles driven. I was driving on the interstate 3 days ago and the car just dies, with a full gas tank, 103 degree temperature and 2 children in the car. Try crossing major interstate traffic @ 80 miles an hour with 2 children, if this is not a safety issue I don't know what is. We had to tow the car and took it to a mechanic and he said the problem with the fuel gauge is located in the same mechanism as the fuel pump and caused the fuel pump to become so corroded that it stopped working. The need exists for an immediate safety recall, before there is a death or serious injury due to a mechanical default that has affected thousands of gmc envoys and gmc refuses to stand behind their products because it is not a safety issue. It is a safety issue......

Fuel gage in our 2006 gmc envoy first became erratic then failed. Took vehicle to local reputable repair facility. They informed me that the sending unit on the fuel pump is known to fail in this vehicle. Had to replace fuel pump (I was told fuel pump and sending unit were one piece). The fuel gage began to work again once fuel pump/sending unit were replaced. The total repair was expensive (parts and labor).

2006 gmc envoy fuel gauge started to work erratically - would go to empty after car was filled up. Eventually stopped working altogether and the check engine light would cycle on and off. My wife drives this truck to work and could have a serious problem if she ran out of gas on the freeway. Luckily, the first time it ran out of gas was in a residential neighborhood. Took it into the shop and was told that they couldn't just replace the problem part (which is the fuel sensor) and need to replace the entire fuel pump at a cost of nearly $1100.00 updated ivoq 08/24/10

Fuel system: the fuel gage has been going to empty after a fill up. After about 50 miles it would appear to work until more gas added. Now it is in total failure with an obd light intermittently. Obd light useless as no way to immediately determine if the gauge is the only problem. Have been using the trip odometer to approximate fuel remaining for more than 10k miles. Fear is that the associated fuel pump will fail as is all one part.

2006 gmc envoy - fuel gauge shows empty regardless of how much fuel is in the tank. Since I have no idea how much fuel is remaining, I have run out of gas several times, including a couple on the interstate. The problem started around october of 2008, but costs almost $700 to fix, started at 37500 miles so it was just out of warranty, and there are hundreds of postings online about this problem stating it's a defect with the fuel pump.

My 2006 gmc envoy's gas gauge has been fluctuating from empty to full on fill ups for over 2 months and now it is stuck on empty even when tank is filled. My mechanic said it would cost $800 to replace the fuel sending unit and fuel pump. Many other owners have similar issues.
