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 HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

This has been the worst vehicle I have ever owned. I've replaced all exterior lights at least twice. That's not even then biggest problem. I haven't been able to pass emissions testing! The check engine light came on, of course shortly before testing. I replaced the oxygen sensors in accordance with the codes. I also replaced a leaking fuel pump. The check engine light was back on in a d...
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.

GM replaced the radio free. So...
Best highway car/truck I ever owned, great on long trips and holds road when semis whiz past. Small problems like leaky A/C (condensation) and mediocre gas mileage bring it down a notch or two.
