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.

2004 Chevrolet Trailblazer Owner Comments

My complaint is on the Chevrolet Trailblazer. I have personally witnessed at least 8 instances in my area where the brake lights on the Trailblazer don't work. The 3rd light on top of the lift gate works, but the regular brake lights don't work. Every time it has been both of them not working. That leads me to believe it isn't just a bulb being burnt out. I have luckily not witnessed any accidents resulting from this issue, but my father owns a Trailblazer and if there is something wrong electrically causing this problem I don't want the same thing to happen to his resulting in him potentially being rear ended. I saw one on I94 just East of I696 yesterday. I notified the woman and she said that she knew so hopefully it is just the bulbs, but I don't know for sure.
