2004 GMC Envoy Problems

Rear Suspension Low Due to Failed Air Compressor

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

Erratic Fuel Gauge Operation

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.

I think that speaks for itself. I completely understand normal maintenance but this car goes way beyond normal maintenance.
Over 144,000 miles on this Envoy. Have replaced brakes, shocks and struts, tires (once O/E Michelins went over 124,000 miles, kept them rotated and at a constant 36 psi) Other than a few odds and ends has been a very good vehicle. Bought it new and planning on keeping it for a while.
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!
