Gas gauge bounced around intermitently for weeks regardless of fuel level. Now it just reads empty. Air compressor hasn't worked since last November. Fuel pump went out last night. Remote keyless entry has never worked. Check engine light is always on. What a lemon. Will never buy GMC ever again.
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.
GMC Envoy denali xl 2006 fuel guage issue. 1st incident - fuel guage showed 1/4 tank gas available while travelling in I-70 IL when vehicle ran out of gas while travelling at 65mph passing semi truck. Other vehicles behind me had to react to immediate slow down of our vehicle. Managed to successfull pull over to verge of road without incident. Not realizing fuel guage was faulty a week later similar situation occured - ran out of gas as I was pulling up to an intersection - lights had just turned red and I was unable to apply enough pressue to brakes as we were heading downhill that I went through red light and 2 cars had to take evasive action to avoid crashing in to me. 2 young children in car at the time of incident. Realizing there was an issue - entire fuel pump system was replaced - total cost over $800.
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.
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 to work again once fuel pump/sending unit were replaced. The total repair was expensive (parts and labor).
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.
The fuel gauge shows empty even when the tank is full. After the gauge has read empty for a while, the engine light then comes on. This is going to cost me 724. 00 to get fixed, b/c the fuel pump needs replacing.
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.
