I filled my gas tank on my 2003 chevy trailblazer ext. And got a gas smell, shortly after the check engine light came on. There is a leak in the fill and fuel pump area I guess. I was referred to see if there were any recalls for this defect and came across this. The garage did a temp. Repair with silicon that only lasted 3 weeks. Now the same thing is happening. I would have to change the entire gas tank to fix this issue.

Began to smell fuel from the rear of my 2003 trailblazer ext. I had received a letter from gm stating the filler neck some times cracks and would be fixed without cost. I took the vehicle to my dealer, they dropped the tank and said the fuel module was corroded and they would replace the tank but want 625.00 dollars to replace the fuel module. And will not release my vehicle. I told them to put it back the way it was and they said they can't.

I have a 2003 trailblazer with 73,000 miles on it. Just recently we are smelling gas fumes really bad to the point it makes us sick and is also hard to deal with one car having to be dropped off at work, etc. I have 3 children and have parked the vehicle because number 1, I feel like this is a big safety hazard for my children and number 2, I cannot afford to repair this after reading all the comments on the internet ($900.-$1000. To repair). It sounds like there are a lot of people dealing with the same thing. Can you tell me where to go with this situation? Am I suppose to contact gm, and if so are they doing anything about this problem? Thanks, sandy nosker

I detected a strong gas smell and took the truck to be repaired. I was informed that the fuel pump module was leaking due to being rusted out. I took it to the dealership (jeff wyler). They agreed to cover the repair of the gas tank and the labor (due to a special warranty due to other fuel leak problems), but would not cover the cost ( $454 + tax) which was the part that was the cause of the problem. The assembly of this part is unpainted medal and rusts very easily (most other company use plastic assembles to prevent this very problem). The location of this part makes it almost impossible to wash, in order to remove any salt or other corrosive elements. I do not see a way that I could have prevented the rusting of this part. I believe this is a design defect that chevy should have to correct, due to the fact that it could have very easily cause a fire to the vehicle due to the amount of fuel/vapor leaking.

2003 chevy trailblazer ext ? Smelled gas, no visual sign of leaking, smell got continuously worse and could smell in the cabin. Then you could see gas dripping from the tank. Had to have the fuel sending unit replaced. This is a very serious problem and we were fortunate that no one got hurt. Feel this is a poor design for the vehicle and it should be recalled before someone gets seriously hurt or killed. This failure occurred around 46,000 miles.

Several times happening in the outside vicinity of my vehicle I could smell gasoline. Took my vehicle to the dealer and described my problem to them and expressed my safety concerns about the gas smell. They advised me my vehicle should not be driven until they could inspect and diagnose the nature of the gasoline smell. Dealer inspected and found the fuel sending unit and line to be corroded on top of the gas tank and it was leaking fuel onto the tank. Dealer in process of replacing fuel sending unit with a new unit. Cost of repair quoted at $840 dollars. Dealer gave me a discounted quote "to help make things right" of around $340. Vehicle is a 2003 chevy trailblazer with 65,000 miles. Seems unacceptable to me for a 4 year old vehicle to develop a problem of this nature.

I have a 2003 chevrolet trailblazer ext. The "service engine soon" light came on. I took it in to a chevrolet dealership. It was found that the gas tank was leaking gas and the tank would not hold pressure thus causing the light to come on. The tank was leaking where the filler neck attaches to the tank. The dealership service director stated that the the crack was clearly a defect and was not caused by damage or misuse. Because the vehicle was out of warranty he stated the repair would be at my expense and would be approximately $750-$800.00. I phoned chevrolet customer assistance and filed a complaint. After they communicated with the chevrolet district service rep. They concluded that gm warranty would not pay for the repairs, even despite the danger and liability involved. They did suggest that if the dealership would approve, to have them do it at the dealership cost. The gm customer assistance rep stated that my only other form of arbitration was through the better business bureau. As of this date the repairs have not been made. I have found quite a number of trailblazer owners on the internet who have had the same problem and have had to pay to have the repair made out of pocket.

I have a 2003 trailblazer ext. Just got it from my in-laws, only 21k miles on it. Gasoline vents on the ground when filling the tank full. The check engine light remains illuminated. I counted more than 20 complaints just like mine on the federal safety agency complaint list. Example odi id numbers are 10191706, 10190967, 10188345, 10187405, 10186556, 10185694, 10184336, 10183773, 10182724, 10182384, etc. I assume it is a cracked filler neck. I called gm customer service. They seemed helpful and gave me a case number, but advised me to go to a gm dealer for an official diagnosis before they can proceed with helping me further. No promises at this time. I assume I'll have to pay for the diagnosis. This is a dangerous malfunction, it causes fumes, odors, and puddles of gasoline beneath hot vehicles.

I own a 2003 trailblazer and recently I began smelling large amounts of fumes and fuel spilling onto the ground when filliing the gas tank. From my research, I've found that based on the symptoms listed above a manufacturer's defect on the gas tank was honored on the 2002 model trailblazer but was not being issued on the same design flaw on the 2003 model. It was stated that this was not a safety hazard which is hard for me to come to terms with. Gm has stated that it would cost $1200 to be repaired at the customer's expense which is just unacceptable since this is the same problem carried over from the 2002 model.

I own a 2003 chevy trailblazer ext. I began smelling gas, and soon after noticed it leaking from my vehicle. After taking it into my local dealership it was found that my fuel module and gas lines needed to be replaced because of corrosion. Because of the word corrosion it then voided being covered under my extended warranty. The SUV sat at the dealership for 5 weeks because of a national backorder on the fuel lines. So, with having no vehicle rental would not be covered because it was not warranty work. I was stuck with a $900.00 bill on a vehicle that was three and a half years old.

My 2003 chevy trailblazer ext, check engine light came on. Took it into the dealer and said the code it was putting out was p0440 evap leak small. After further investigation there is a small fracture on the gas tank where the filler neck meets the tank itself. I have read of many similar problems of 2002 and 2003 trailblazers. This seems to be a safety hazard. Although they said no fuel was leaking out of ours, it was leaking vapor. Vapor seems more dangerous than an actual fuel leak.

I own a 2003 chevrolet trailblazer w/ 69016 miles. My service engine soon light came on so I took it into bill heard chevrolet where the veh was purchased to check the reason for the light. I was advised by the service manager that this was due to a leak in the gas tank and that the repair would cost approximately $1000. I took the vehicle home to have a second opinion done and do further research on the problem. I have found doing a google search that this is a common issue with the 2002-2005 chevr trailblazer. So I contacted the dealership and they stated that their have been no recalls and that gm is not anticipating to have one. This is a fire hazard and major safety issue. How can this not be recalled?

Since july 2006, mileage 49,000, we have had our check engine light come on many times for the same code. After many trips to the garage, and many things replaced, on jan 31, 2007, mileage 55,802, the dealer told us that I should not drive it home as it could be a fire hazard as there were cracks all over the top part of the gas tank by the filler hose. A new tank was put on and cost came to $832.74. I spoke with customer service at gm and they said gm would do nothing for reimbursement. Since then, I have seen many vehicles posted on the web that have had to have there tanks replaced. If this is a safety concern and fire hazard, why is this not becoming a recall, and why is gm not being held responsible for any of this? I don't think a vehicle with 49,000 miles on should have to have a tank replaced. Thanks for your time.
