A guide to problems, costs, maintenance and repair for your 2007 Chevrolet Trailblazer SS

2007 Chevrolet Trailblazer SS Problems

Air Compressor for Rear Air Springs May Fail

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

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.

Flush cooling system every 60,000 miles

GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.
