I have this continual gas smell coming from somewhere in the vehicle while it is parked and while driving. It has only just recently started. I'm not sure if it has anything to do with a recent Valvoline oil and tranny fluid change. Does anyone have a clue?

Back in October 2008, I received a letter to make me aware of an issue with some 2004 Chevy Trailblazers in certain states (CT, Del, DC, Ill, Ind, Iowa, Maine, Mryld, Mass, Mich, Minn, Miss, NH, NJ, NY, Ohio, Pa, RI, VT. WV, Wis). "Corrosion may cause small perforations with fuel tank modular reservoir assembly. Perforations may allow small amount of fuel to accumulate in a recessed area outside of the fuel tank. If this were to occur, it would be accompanied by a fuel odor. If left uncorrected and the corrosion is allowed to progress, a fuel spray from the pipes may begin to occur."

Thanks for your info. I have since taken the Trailblazer in for repair. I also found out there is a recall on that exact revservoir assembly. It seems that those metal pipes you were referring to are the only metal parts and on my Blazer the pipes snapped and sprayed fuel out when the mechanic put it on the rack. Very dangerous! The parts are expensive, about $550 alone + labor. There is a reimbursement form through GM you can obtain if you don't take it to a GM dealer for repair..

I see it's been a few months since anything was posted on this subject. I found this info through a simple search and it has proved very helpful. I live in PA and about 2 weeks ago I detected an odor of gas near the rear of my 2004 TB Ext. I did not see any sign of a leak at 1st but after a few days I did notice a stain on the driveway. I printed out the info above and brought the TB to a local Chevy dealer. The dealer verified that the reservoir assembly was rusted and leaking and that the gas tank was also rusted. I was told the reservoir assembly was covered but the gas tank was not and that would cost $600 to replace! I objected, stated that I felt it was all related to inferior manufacture and that this is a serious safety issue. I asked for the number of the regional service rep and the dealer provided me with a toll free number. After negotiating the menu system I reached a rep who took my info including VIN & mileage (65K) and forwarded to a local regional service manager who contacted the dealer and myself a few days later. I was just informed today that GM would cover the entire cost of the repair! I haven't had a whole lot to complain about with the TB. I replaced a driver side front wheel bearing 2 months ago, that part was only available through GM and cost about $250. The A/C stopped working at the end of the summer & the system won't hold a charge so I still need to have that checked out. I get fairly decent mileage with the straight 6, almost 20. I'm beginning to feel, though, that it's starting to nickle & dime me. Thanks for the postings, it was a tremendous help.

I just posted a message on a gas leak on the 2004 TB & forgot to mention this. I had about 60K miles on the straight 6 when I noticed an exhaust leak that got progressively worse. I brought it to a local shop who replaced it for me and was told when he went to the dealer for the part that "we have sold a few of these." The shop had a heck of a time, about half the bolts would not come out & had to be drilled. Good thing the 6 gave then just ehough room to do this. I wonder how prevalent this problem is & if anyone else out there has encountered it?
