2007 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.

2007 Chevrolet Trailblazer Recalls

Driver's Door Window Switch Shorts And Catches Fire

The driver's door power window switch module may get contaminated with liquids causing a fire hazard. Dealers will replace the driver's door switch module free of charge to resolve the concern.

Headlights & Daytime Running Lights

These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

Power Door Locks And Windows Do Not Operate

The module that operates the power window and lock switches can allow moisture in, causing corrosion that can lead to a short circuit. This results in window and lock functions not working, and creates a fire risk. Dealers will inspect and replace affected modules free of charge to resolve the concern.
