2004 GMC Envoy Problems
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.

The check engine light was back on in a d...
This car is the worst problem I have ever had. I would never recommend this car to anyone. The car always has something wrong with it. They even know my car already when I go in the parts store. I think that speaks for itself. I completely understand normal maintenance but this car goes way beyond normal maintenance.
This has been one of the most trouble free vehicles we have ever owned. The I6 has good power and throttle response. The gas mileage is less than ideal, but hey its an SUV.
