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

  • 59,000 miles


My 2004 Trailblazer only had 59,000 miles on it when the speedometer began not working. Some times it reads I'm going 80 when I'm at a stop, other times (maybe one day out of 10) it works fine for about a day. The fuel and oil gauges are also not working correctly. The fuel says it is past full until it's completely empty and the oil does the same. The check engine light also comes on a lot for no reason. I also have a right tail light and blinker out even though I have had the bulbs changed. I have had a mechanic look at the wiring/electrical and can not find a problem. The estimated total repair costs are $1100 so far.
