Chevrolet Trailblazer SS Problems

Reduced Power and Check Engine Light

The throttle position sensor (TPS) on the 2008-2009 Chevrolet Trailblazer SS is known for failure which causes:

This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.

To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.

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.

Chevrolet Trailblazer SS Recalls

Door Window and Lock Switches May Stop Working

Fluid may enter the driver's door module, causing corrosion that could result in a short circuit in the door module. A short circuit may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing an odor, smoke, or a fire. Dealers will inspect the driver's door module, if it is functioning correctly, a protective coating will be applied. If the module is not functioning correctly, it will be replaced. The GM recall number is 12180.
