I have a 2004 chevrolet trailblazer ext with 161,000 miles on it. A few weeks ago I got to noticing a real strong gas odor in and around the vehicle. I have done a lot of research and have had the vehicle checked out and came to the conclusion that it is the common problem that is affecting many other trailblazer ext owners. It is the fuel tank inlet check valve at the top of the fuel tank. In doing my research I have noticed that many people have had this issue fixed by some recalls that have been issued so I took the vehicle to my local chevrolet dealer to find out about it only to be informed that mine is 41,000 miles past the recall mileage and will cost upwards of $1,000 to fix. I am worried about a possible fire or explosion with this issue. I am afraid to drive it to work every day and to use it to take my children to school. I just wish that chevrolet would fix this so I don't have to worry every day about driving it. I don't feel that there should be a mileage restriction on a safety issue that could result in death or great injury.

Several months the smell of gasoline was very strong in the interior of my SUV. I drove it about five miles from my home with a full tank, as I drove it the smell became much strong, when I reached my destination a person pointed out to me that gasoline was pouring from the bottom of my truck like a water hose. I immediately returned home to park the vehicle. As I tried to recall what may have occurred, I remembered that two days prior to the incident I got an oil change; I assumed that maybe they had done something to aggravate an already existing problem. After they reviewed their work, I was told it was a manufactures problem. I later took the vehicle to wolf chevrolet (now defunct dealer). A diagnostic was done and it was determined that the gas tank must be replaced with a cost of $1192. And the SUV is considered "too dangerous to drive". I then went to another automotive establishment and was given the same diagnosis. After taking in consideration both estimates and my need for transportation, I contacted gm and spoke with a customer service representative who informed me that I needed to take the vehicle to a certified gm dealer. I took the vehicle to lou bachrodt in cherry valley, illinois and was given the same diagnosis. Afteri relayed the iinformation to the gm rep, he said that due to the age of the vehicle and the mileage, gm would not be able to offer me any compensation. He suggested I phone lou bachrodt and see if they could assist me in the cost, the service technician gave me the same statement; age and mileage. I am writing because from all indications this problem is not only prevalent in my SUV but after doing research, several 2004 chevrolet trailblazer owners have experienced similar problems. It is my belief that chevrolet gm should take ownership for all or some of this problem.

Due to a service engine soon warning light and smelling gas inside my vehicle, I took my vehicle to my local mechanic. He stated there was a crack in the neck of my fuel tank. The tank needs to be replaced. He also stated that this is a common problem with trailblazers. I looked up any recalls. Found special coverage adjustment - fuel tank inlet check valve fracture#07099a. I called a local dealer who confirmed that was right. However my VIN # does not fall under VIN #'s listed. The dealer called a local gm rep. And I was offered 40% covered by gm meaning I would have to cover the other 60%. I do not understand why only some VIN#'s are in this and not all of them. It seems that this a problem that is very common in these trailblazers. I do not feel safe driving my family of 5 around in this trailblazer with a fracture fuel tank inlet check valve and the strong smell of gas in the truck and risk of fire from gas leaking out. This should be a recall item so that those of us that have trailblazers not with in the VIN #'s covered can get this fixed and be safe. Chevrolet/gm should step up and make this a recall this is a huge safety issue.

My vehicle is currently parked in my family's garage, as I am experiencing a strong gas smell. There is no visible leak, but I do not dare to transport my children in the vehicle until I can find what the gas smell is originating from.

The ext. Manifold on my 2004 trl blazer has a leak in the maifold body. The vehicle has approx. 120000 miles on it. This should be a recall item for manufacturing defect, but gm has not as of yet, issued a recall. It is a costly repair, as well as a safety concern, given that the exhaust fumes can enter the passenger compartment of the vehicle. I have owned many gm vehicles overtime, and never seen this before.

The fuel tank is leaking. The fill tube separated from the tank and is leaking fuel onto the tank. There is a strong fuel odor as well. Called chevrolet they stated that vehicles are only being repaired for this issue in northern, eastern and midwestern states. Stated they will not fix my issue though it has the same issues covered under the special coverage, due to my geographic location.

I own a 2004 trailblazer ext with the i6 and I've been getting strong smells of exhaust fumes inside the vehicle do to a faulty exhaust manifold that is cracked. It seems that it happens to 90 percent of the trailblazers with the i6 motor. Come to find out that the exhaust manifold is on national back order which tells me that gm should do something about this seeing that it's hard to drive around with the windows up and the heat on. Not only is it a safety hazard but it's also an emission issue.

My wife's 2004 trailblazer ext service engine soon light came on in late september 2009. She had been complaining of a gasoline smell after filling the vehicle. I had the obdii code read and it was code 0440 evaporative fuel system - small leak. I was told to replace the gas cap, and it did not remedy the problem. I then found out that the 2002-2004 trailblazer ext had a known problem with the gas tank filler necks developing cracks and causing the ses light to come on and gas to leak when the tank is filled or near full. I contacted chevrolet, who stated that out trailblazer is not in the VIN range of trailblazer ext's that were covered by a special notice that allowed the tanks to be replaced under a special extended warranty. The replacement cost is $900+. This is a known problem with 2004 trailblazer ext, outside of the narrow VIN range that chevrolet will admit to. All 2004 ext's should be included in the extended warranty. Our vehicle just turned 60,000 miles.
