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.

Trailblazer 6-cyl

"service engine soon" light would flash on then immediately off, truck would feel like it momentarily lost power while driving. Recently the fuses for all the gauges have been blowing out repetitively. The speedometer does it more than the others. Have replaced them several times in the past three months. Chevy was helpfully "guessing" at first but finally told us there was nothing they could do towards the end of our 3 year warranty. We haven't taken it back to them for the ongoing problems.
