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.

On several occasion over the past year my fuel gauge in my 2004 Chevrolet trailblazer lt has read inaccurately leading to breaking down due to the vehicle running out of gas while the gauge was still reading at least 1/4 tank moments before the engine stalls. On all occasions I was driving on the freeway the gauge showed 1/4 tank and then all od a suddenly dropped to E with the fuel warning light coming one. Within a few miles of this sudden drop and the warning light coming on the engine would stall due the vehicle being out of gas. I have complained to my local dealer on several occasions and all they have offered to me is to replace the sending unit, which in this model is integrated with the fuel pump at the cost of almost $800. This seem wrong to me. Now that I have read that this seems to be a problem on these types of vehicles I am even more upset that the local dealership told me my issue is an isolated issue and they have never heard of any problems with the fuel gauges in these vehicles.

I own a 2004 Chevy trailblazer. I purchased it used from a dealer in December of 2010. I notice since I have owned it that there is something wrong with the gas gauge. It will show a decent amount of gas in the tank then by the time I get out of my driveway it is showing empty. It will go up and down all the time. I know I am not out of gas, because I make sure to put gas in every day because I am not sure what is in the tank because of this problem. I was going to take it to a mechanic to have them look at it and fix the problem. Since seeing that an investigation is being done for the same exact problem, I decided to write here first. I am requesting that the years investigated also included 2004, since it is the same problem that is being investigated by your Agency.

2004 Chevy Trailblazer ext, gas gauge gives inaccurate reading even we car is in off position, when car is started gauge buries itself and goes well beyond full mark driver cannot depend on accuracy leading to running out of gas on major highway or bridge.

On July 26 the fuel tank broke and the fuel pump went out also on my Chevy trailblazer it was two days before I had it for 30 days I called the dealer and they said that they couldn't do nothing we paid about $2800 dollars to get it fixed you could smell the gas inside the car I was very worried being that it was harmful to my kids and I let the dealer know that and then a week later we got a recall letter from Chevy about the problem the dealer never gave us the car fax report like it states in there dealer front door I would like to do something about this.

The gauges on my 2004 Chevrolet trailblazer do not work. I had this same problem several months ago and took to dealership to fix, they said there was nothing wrong. Now my warranty is out and they again are not working. It is not safe to drive when the speedometer, tachometer, oil gauge, and temperature gauges don't work. Apparently this is a problem that many owners of the same model have reported and nothing has been done about it. This is a safety hazzard and should have a recall associated with it with chrevolet footing the bill. I guess it won't be addressed until deaths or injuries are associated with it.
