GMC Envoy Problems

Erratic Fuel Gauge Operation on GMC Envoy

Problem Description and Possible Solution

The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

Fuel gauge started to fluctuate between full & empty. Week later after starting the rig, fuel gauge would slowly fall to empty (regardless of fuel level)and stay on empty. Now stays on empty even when full. Keeping track of mileage for fuel level. Really GM? Recall, Recall, Recall...
Started having this problem about a year ago. Haven't had the problem fixed yet. Received the letter from GMC a few months ago. Can't understand why GMC will only pay half the cost?? There are several sites on the internet talking about this problem, so it's obvious that there are thousands of other customers who have this same problem. This site says that GM has extended the warranty to 10 years/120,000 miles, so if it's under warranty, then why should WE have to pay anything???
Gas light stays on most of the time. And gauge goes up and down at will. GM should have recalled this junk called ENVOY!!!
The problem I have is the floater is sticking on the GMC Envoy XL 2004. Is there a solution to this problem besides taking it to the shop? There is no recall that I know of.
Fuel gauge stopped working years ago. I was relying on the milage. I finaly found someone that had the float arm and contacts available instead of purchasing the entire fuel pump. It cost me $45 for this piece instead of the $400+ for the pump. Easy enough job, but make sure you have at least one complete set of fuel line clips as they will break off when you start pulling the fuel lines apart. GM dealer will tell you you need to replace the entire fuel line at $50 esch...not true.
Fuel gauge "floating" between full and empty w/a full tank of gas. Today after filling tank, gauge stayed on "E"!
Fuel tank gauge moves all over- when i start up in morning gauge goes to where it should then after 10 minutes goes down to E. GM should recall this!! Plus the divers side window doesnt work either! I take care of ny cars! GM I am really disappointed in you
I just purchased a 2007 GMC Envoy SLT and filled the tank up. The third day driving it the gas guage went to empty and the low fuel warning beep and display came on. I couldn't believe I was out of gas but because I was unfamiliar with the vehicle I put more gas in and of course it did not take much gas becuase my tank was still almost full. When I started the vehicle again the guage went back to full and acted normal for another day. Now the same thing is happening everyday. I start the vehicle and the fuel gauge reads properly and then after a few minutes of driving it goes back to empty again and the low fuel warning light and beep comes on. I now am relying on the trip monitor to keep track of how many miles I have gone and can know when I really need to put gas in. I contacted GMC to see if they had any record of this problem and the lady told me no. GMC made me an appointment to have it looked at by the dealer and said depending on the outcome they may be able to help with the expense of the repair since it is still under 100K miles although the fuel guage or pump are not covered by the powertrain warranty that is still in affect. I am bringing it to the dealer next week and I am afraid of what I will hear. I paid 14K cash for the vehicle and did not plan on spending another 1K on repairs!!
Same as others. Erratic fuel gauge... goes from E - F regardless of the fuel level. Plus it makes the check engine light come on.
Started out with the fuel level indicator being all over the place and then showing empty. Now the level indicator does not work at all and low fuel light always on. Has not been fixed yet.
Gas light was on so I filled up and after filling up went to crank car and it didn't crank as easliy as usual, gas light would not go off and gauge stayed on E, finally the check engine light came on. The next day took to a shop to be looked at and gas gauge was finally reading and low fuel light finally off...they said they are not 100% sure because it is running fine now but they think the fuel pump is slowly going out have not replaced it yet $795 to do so so trying to hold off till after Christmas I just bought this car used 4 months ago URGH! Wondering if this is something that is covered under the original 100000mi warranty...have not had a problem with it since I got it back from the shop two days ago and this morning I stopped at gas station and I still have 1/2 a tank of gas...left it running and when I got back in my car low fuel light on again and gas gauge reading E as I drove to work this all went away and it is running normal again.
vehicle always showed gas level on "E"...then one day vehicle just cut off because gas was low...never experienced running out of gas before...
