Chevrolet Trailblazer Repair and Maintenance

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

Chevrolet Trailblazer Problems

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 HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Chevrolet Trailblazer Recalls

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.

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.

Vehicles first sold, or currently registered, in certain states where salt is used to de-ice the roads are being recalled because fluid may enter the driver's door module, causing corrosion that could result in a short in the circuit board. A short 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. As of this time, the remedy plan is still being finalized and a notification schedule has not been determined. The GM recall number is 12180.

The lights dim when you use the windows, the center console has no support, the seats are falling apart, wind noise is unbelievable, and speakers are all out of wack s...

I have had nothing but problems with this vehicle after the first year and Chevy dealership would not do anything to help. I have had the fuel sensor go bad, the fuel pump, fuel contector, the shocks and struts have all been replaced within the first year. I used to be a chevy buyer all my life and lately have no faith left in Chevrolet.

Bought my vehicle from Enterprise with 6700 miles on it. It is 4wd with the in-line six with almost 300 hp. It has performed well overall with 20-21mpg avg if I keep below 70 on frwy. All add-ons like ac/stereo/power windows, mirrors, door locks/etc all still work fine after three years. Interior is 2-tone with camel colored seats and upper part of SUV and black carpets and dash area. The...
