Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

Fuel gauge has been fluctuating wildly for a couple of months, generally reading empty (even after fill up) but occasionally full (when a fill up is needed). Dealer said fuel gauge sensor was bad & that it would be approx $900 to fix. Looking into the problem online I see there are thousands of people with the same problem.

2004 Chevy Trailblazer fuel gauge not working it goes around in circles does not measure fuel and has caused vehicle to run out of gas, the gauge started measuring incorrectly, then moving from full to empty going in circles now its stuck arrow pointing downward, my family and I were lucky that the vehicle behind us was not speeding or else he would have slammed into the back of our SUV and caused a serious accident.

Instrument panel failure, ran out of gas on a busy four lane highway during morning rush hour. I was in the left hand lane and was unable to move to the shoulder. I now became a major traffic problem until some nice citizen helped me push the truck out of harms way, having to stop both lanes of traffic so I could cross. Had I a working gas gauge I feel this would not have happened, none of the instruments in the vehicle work, Chevy has recalled other models of this year with the same problems, but not the Trailblazer. Why?

The gas hand and the tachometer are not accurately calculating. The gas hand is halfway between the E and the F (at the 6 on a clock) when the tank is full and various times of the day, it moves all over the dial.

Daily failure of seedometer on my 2004 Chevrolet Trailblazer. This was in addition to failure of the fuel gauge. The speedometer problem was inconsistent and made me question the actual speed at every moment and made me measure based on other traffic. It is a very distracting way to drive with all gauges moving at times and then returning to a fixed setting. I had the clusterboard replaced by the dealer who claimed this was not a common problem. Instrument panels on 3 year old cars do not fail unless there is a manufacturing problem. Please prevent accidents in the future this is not a safe way to operate a vehicle.
