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.

Whenever I drive at night the exterior and interior lights flicker and sometimes go out completely when I brake or allow the truck to coast. When I use the gas the problem resolves but since I have to stop sometime this isn't a good fix. The electrical gauge on my dash fluxuate with the lights going from low to high and back again. I've taken into 2 dealerships but they "can't duplicate the problem" I work nights so I am driving mostly during the night. How is it save for a young woman to drive alone at night without lights? this is an ongoing problem that has happened since I purchased the truck and has not been resolved.
