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.

CarComplaints.com Notes: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

I own a 2004 Chevy Trailblazer and the speedometer has progressively gotten to the point of being completely inoperable. The first time I noticed the speedometer read 120 mph when I was driving on the highway were the speed limit was 55 mph and I was driving with the flow of the traffic. I turned the car off and the speedometer still read 50mph. As of a month ago my fuel, oil, battery, and temp gauge are all inop; the needles never move. With this my battery, seatbelt, ABS, and parking park stay illuminated. This is a safety concern because I never know how fast I'm going, how much fuel I have, if my car is running hot, I have no warning indication of anything going on with my vehicle.

2004 Chevy Trailblazer 4WD fuel gauge not accurate, going from F-E while driving after filling with gas. From online research this is the fuel sender problem that is a wide problem from all Trailblazers.

My 2004 Chevrolet Trailblazer developed a leaking fuel tank and I keep getting "service engine" lights. I understand there have been many complaints however GM has not called for a recall. This is a serious safety hazard and appears to be a common problem. Reference complaint #05012.

Bought a 2004 Chevy Trailblazer and fuel gauge is not working on it. Quit right after we bought it. We had also bought a 2000 Chevy Silverado in 2004 fuel gauge went out on it, it has the electronic sensor/sending unit built onto the fuel pump. Fuel pump works great just the sensor is broke. What is with these on the Chevrolet. I have heard of others with same issue on their Chevrolet.
