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.

Well I bought this SUV used from americas carmart in gadsden Alabama.they have a 100 plus lots and advertise good used qualtiy cars..when I bought the SUV I wanted to take it to the Chevy dealer but was told their on site certified mechanic checked it all out and with the service agreement thought I was ok....had it two days and the transmission went out..the suspension was also an issue then 12/21/2014..going past 50 it shook like crazy....and then the transmission was slipping againi purchased a service agreement for $ covers what my problems are...but the contract says they can use non manufacter parts which is fine...when I brought it to them with the transmission..they put a junkyard salvage transmission with 100.000 miles on it...when I called them in December about the shaking and suspension and the transmission...they said bring it in...I asked them where they were going to take it..they refused to tell me...and I told them I didn't want a junkyard suspension or transmission as per contract was not suppose to happen..I also asked for a certified mechanic to do the work...they said they would see what they could do.I do a lot of driving in Tennessee..alot of mountain driving and I was not going to have the front end {ball joints, etc go out there..not real safe..they came and got the car...I thought they were going to fix it as agreed...that was on the 8th of they say they are going to sue me for the remaining balance....I just want to call attention to this SUV as it is not safe..and its my opinion they do this a lot to other people...I wanted to draw this to your attention as I would feel bad if I heard of someone getting seriously hurt..due to their inability to sell quality used cars as they advertise...and believe their practices on repairing these cars with a service agreement gets checked into..I filed a complait w/the ftc and agoffice.

I have a 2004 Chevy Trailblazer and the cluster is going bad. Finding out that I'm not the only one that has this problem. I had the same problem with my Chevy Avalanche and it was recalled. I think that this a problem while driving. I think someone should do something before someone gets hurt. Because the gauges go out the on and while driving. It could hurt a young driver that doesn't what to do. GM knows the problem but will not do anything about it. It the same problem that they did a recall on with the trucks. So I think they should fix this problem. So could you please help before someone gets hurt bad over this problem. Thank you please help!

While driving along my tachometer and speedometer on my 2004 Chevy Trailblazer dip below zero. I took it to my mechanic who said the electrical is shot in the dashboard area. My vehicle has to be running for 30 min or more for it to act up. If I leave cruise control on the needle stays, once cruise is turned off I'm doing (hopefully) 70 while my speedometer says I'm doing 20. Searching on the internet I'm not the first to complain about this. Has Chevy recalled the dashboard unit in the 2004 Trailblazer yet?
