My fuel tank has a hole in it. I have filed a previous complaint with the federal safety agency and also with gm. An the federal safety agency worker helped me a lot and when I called gm and chevy back I was told several times someone would get back in touch with me. I have tried to get it fixed but no one is able to help. I have tried many places for used fuel tanks but everyone says that the envoys and trailblazers that they have all have the same exact issue. I cannot get any help from gm or chevy.

Starting about a few weeks ago my 2004 chevy trailblazer ext has reeked of unspent gasoline, and this smell consumes the entire interior and exterior of the vehicle. The vehicle also has small leak below reservoir which appears to be leaking unspent fuel. Chevy offered a "special coverage" to correct this issue (corrosion on top of fuel tank reservoir), however it only covers vehicles under 10 years of age and under 120k miles. My vehicle is under that mileage, however this repair will not be covered due to age of vehicle (mine was assembled in march). This issue is a major safety concern, as any small spark could cause this vehicle to ignite. I cannot continue to drive my vehicle, and feel this needs to be rectified before it causes catastrophic loss (either building or personal).

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.

I began smelling gas from the vehicle and noted that there is gas dripping from around the gas tank. I contacted my mechanic and was told that this is the third trailblazer he has seen in 2 weeks with the same problem. Chevrolet advises that there was a fix which was good only until 120,000 miles. How am I supposed to know to take it and have it fixed before 120,000 miles if I am not notified by gm? This obviously is a serious safety issue involving the trailblazer which gm is aware of but has thus far resisted recalling.

We were doing our normal fill-up (truck was off) and after we filled it up & turned it over, the fuel gauge shot way over the 'full' mark. Every time we turned the vehicle on, the fuel gauge was reading differently, I have no idea how many times it was right. The oil pressure and battery charge gauge have also been giving false/sporadic readings as well. After much searching, I found the root cause of this to be a very common problem not only in the trailblazers but the tahoes and several other of their vehicles (the instrument clusters are faulty). Given the expansive nature of this issue, and the potential dangers of not knowing your speed, fuel level, oil pressure or rpms, I'm having problems seeing why this isn't a recall already. It seems to happen more in the 2003-2006 models more than others from what I've found as well.
