#5 of 24 2004 Chevy Trailblazer 6 cyl Cracked Exhaust Manifold
Nov 10, 2009 (5:54 pm)
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?

I was just informed that I have the same issue with my 2004 GMC Envoy XL. First thing I asked was whether they've had seen similar cases.

#8 of 24 Gas smell / noisy exhaust
Nov 01, 2011 (10:26 am)
We recently purchased a used 2004 Chevy Trailblazer EXT, 2WD. We've had the vehicle about a month and have now noticed a strong gas smell coming in through the vents. The smell seems stronger when the vehicle is just sitting and we have just put gas in the tank. We have also noticed that the exhaust just keeps getting louder. It seems to be the loudest when sitting in the front, passenger seat. Any ideas on what this could be? I see in the past that there was a recall (in one of the states that I live in). Does this recall ever expire or will the dealership always pay for this repair? Any thoughts or ideas would be appreciated. Thank you!

#12 of 24 04 trailblazer gas smell
Nov 26, 2011 (6:51 am)
I too have a smell of gas coming from somewhere under the truck. A code can up for p0128 but that is for Thermo temp and should have nithng to do with the smell. If I take off the air cleaner I get a real strong odor of fuel. Any suggestions?

On mine the fuel pump canister on the top of the fuel tank had rusted out. At 1st no leak was apparent by a puddle on the ground only the odor and I thought the fuel cap might have been defective. After about 2 weeks drips on the ground became noticeable. I understand this is a common condition especially if the vehicle is operated in northern states and winter conditions where roads are heavily salted. In my case this was covered under the emissions control warranty which is over and above the standard warranty, 80K miles if I remember correctly. If this applies to you you may have to dispute this with your dealer as they don't seem to always offer this info. The cost of the job can run in the $600 - $800 range if I remember correctly. Good luck!
#14 of 24 04 Trailblazer, Gas smell/noisy Exhasust/1&2 ignition coils keeps going out
Jul 11, 2012 (5:10 am)
I have replaced all 6 of the ignition coils in my truck at least twice now, but I'm having to replace the number 1 and 2, constantly, my truck will run for a month tops, and then the smell starts getting stronger, the exhaust gets louder, and one of the ignition coils has went out. Has anyone else had a problem with their ignition coils.
