2004 Chevrolet Trailblazer Problems

Fuel Level Sensor Failure

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 inline 6 cylinder engine in this Trailblazer is one of the best engines from GM in years. Combine this fine engine with a smooth shifting automatic transmission and you end up with a fine running midsize SUV.
