After noticing strong gasoline odors in car and in the garage, the check engine light came on. According to diagnostic test run by dealership, this is the result of a leak in evac system. While researching, noticed other owners having same problem. Called GM, advised no recalls issued for this problem. GM offered no relief. Expressed my disappointment with rep since this problem could lead to very serious consequences thing the problem was caught since could have led to fire had there been an accident or an incinerator nearby. My cost to repair the manufacturers defect is $1600.

Service engine light illuminated due to leak in evac system according to diagnostic test. Smoke test showed leak to be at weld where fill spout tube is attached to fuel tank. Gasoline fumes were present were present from the vehicle. Was infonmed that tank would have to be replaced ala cost of $1200. Did some intemet research and found that GM had a tsb addressing this problem (campaign #05012), but it only applied to 2002 ext models. Since this is, in reality, a fire safety issue, I feel GM should also include other models with the same problem regardless of age or milage. Updated 01/20/11

Fuel neck leaks on gas tank on my 2003 Chevy Trailblazer purchased it from a local dealership on 08/14/10 with 107782 miles on it. We keep it in our garage and (that is also where people go to smoke) shortly after we got it home we noticed a gas smell in the garage so we started looking at it and noticed it. Long story short we took it back to the dealership and they told us the fuel neck was cracked and the purger tank was bad. They tried a silicon on the leak which did not work so they say the tank needs to be replaced. Noticed that others where having the same problem. Called GM to see if they would in any way cover the repair of an known issue, and was told that since I bought it used and it has over a 100,000 miles they would not do anything! now the dealership does not want to do anything, and are mad because I called GM. Then I did a carfax today and notice there is a mileage issue.

Fuel tank leaking at filler neck. Leaking gasoline and very strong smell of gasoline. Notified GM after getting fixed. Admitted there is a problem but no recall available for Texas. We were never notified of the problem. Very thankful it did not catch on fire.

Safety problem with seal where the filler neck meets gas tank. This seal cracks. Gas spills out this seal when fueling and emits a strong gas odor when engine is on or off, more so when car is running. From my research this is a wide spread problem but only ext models are eligible for free replacement but the problem is not limited to ext models. Same defective parts are used on non ext models. Cost to repair is $1400! this is a health concern and fire hazard due to fumes escaping vehicle

I own a 2003 Chevy Trailblazer ls model. The gas tanks leaks where the filler neck connects to the tank. This is a known issue on 2002,2003 and 2004 models. I asked GM for assistance with the tank replacement ($1400) because this is a well known issue with this vehicle. Request was denied because I don't have a history with GM dealerships as in previous purchases. My VIN number did not fall into the special authorization that was issued in 2007 for this issue.

I own a 2003 Chevy Trailblazer V6 ls. I always noted the presence of an odor of gas especially when filling up my vehicle, it grew progressively worse over a two year time frame. Then in July of 2009 the check engine light would come on and go off. I noticed gas dripping from the underside near the gas tank! finally evidence of a leak! a very strong smell of gas and took it to my service garage. The examined the problem and told me I needed a new fuel pump assembly. They repaired it to the tune of $680 dollars. 4 weeks later I was back, still smelling gas. They had to drop the tank again and replace the assembly unit gasket. I think this may be a wide spread problem not just limited to me.

I have owned a 2003 Chevrolet TB ltz and for the past several months I have been smelling a gas leak somewhere but I could not identify where. Recently I found that it was leaking around the neck of the pump where it was corroded and the seal failed. Now everything work well including the gas pump and I have been reading that this problem has been existing on 2002 Trailblazers and later. My TB has 106,000 miles on it and unfortunately out of the warrantly period but this is definitely a safety issue. I am just glad the truck did not start a fire, especially when my family was in it or it was parked in my attached garage. Has there been any recall on the gas tank. I have never been advised by Chevrolet except for the filler neck which I really don't think was a problem at the time with my TB. Please help!

2003 Chevy Trailblazer check engine light came on. Dealer said the gas tank has a crack in it and is not found to be a recall item. We believe this is a safety issue and should be something the manufacturer should warranty under recall.

The contact owns a 2003 Chevrolet Trailblazer. While driving approximately 40 mph on normal road conditions, the check engine warning indicator illuminated on the instrument panel and remained lit until the engine was turned off. In addition, the contact noticed a small amount of fuel leakage whenever the fuel tank was filled to capacity. The driver fills the fuel tank halfway in order to avoid leakage. The vehicle was taken to an authorized dealer for diagnostic testing and they stated that the failure was related to a hole in the fuel tank. The vehicle was taken to an independent mechanic for a second opinion and the same failure was confirmed. The vehicle has not been repaired. The failure mileage was 75,000 and current mileage was 107,000.
