Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Gas gauge reading is incorrect. The gas gauge reads 3/4 immediately after a fill-up and then reads empty soon thereafter.

The fuel gauge does not work properly. It sometimes indicates there is more fuel than there actually is in the tank. Sometimes it shows it is empty when it is not.

The contact owns a 2004 Chevrolet Trailblazer. The contact was driving approximately 30 mph when the check engine light illuminated. The vehicle was taken to a local repair shop where the fuel cap was replaced. The failure recurred within one year. The vehicle was diagnosed and again, located the failure at the fuel cap. The contact stated that the failure recurred three times in which each time; the fuel cap was replaced as the remedy but to no avail. The vehicle was then taken to an authorized dealer and he was advised that the fuel tank exhibited a hairline fracture. The vehicle was then taken to the independent mechanic for repairs in which the fuel tank was replaced. The manufacturer was contacted and a complaint was filed. The VIN was unavailable. The failure and current mileage was unknown.

Check engine light came on; has come on recurrently since (code P0442), which indicates leak in fuel evap system. Analyzed by independent tech and powers-swain Chevrolet (a GM dealer) verifies fuel tank inlet check valve fracture. GM's resolution to date is refusal to act due to age/mileage of car. GM has a recall for same defect on long body 2002-2004 models. Their campaign 07099A is part of their recall. I have seen many other Trailblazer fuel system problems on internet sites. This defect allows fuel vapor (possibly ignitable) to escape in the vicinity of electrical connections. There needs to be a recall on this defect, regardless of age/mileage of vehicles.

On my 2004 Trailblazer, my wife complained about gas fumes in the car. I noticed gas streaming from around the top of gas tank. I dropped the gas tank down and noticed the leak was streaming from one of the metal lines exiting from the fuel pump. The corrosion was so bad I only had to lightly push on the metal line and it broke into. If my wife didn't smell the fumes this could have burst into a fire if it eventually sprayed onto the exhaust system.

Chevrolet Trailblazer has check engine light on. I can smell gas when vehicle is in garage. Looked underneath and found a crack in the fuel tank filler hose flange. Called Chevy and found there is a service bulletin, #05012 and tsb 07076. Chevrolet told me the same problem has been found and fixed on models as the Trailblazer, but my vehicle would not be covered. The reason is my vehicle is registered in Tennessee and is not on the "corrosion list of states". I did not see the difference as there are vehicles documented having the same problem as mine.

2004 Chevrolet Trailblazer ls 4.2 I6-ses light went off while driving. Took it to autozone and the scanner read code P0455. Had a mechanic look at it and he found a crack on the gas tank at the neck where it connects to the filler neck.this repair runs into the hundreds of dollars which I do not have. I haven't even finished paying off the car yet. I researched the problem online and have found quite a few Trailblazer ownerswith the exact same problem.

2004 Trailblazer gas gauge does not work. My husband filled the truck up with gas and next morning the gauge went from E to past F and does not read anything now. This is the 2nd sensor to go out. The RPM sensor also went out a year ago. Talked to the dealer ship, they said to contact NHTSA and let them know. I read online and there are several complaints about the sensors going out and GM knowing they have issues.

2004 Trailblazer, been having issues from 30K miles on with check engine light and they kept telling me bad fuel cap, after about a doz or more new caps now leaking filler tube. Found out this is the cause of the check engine lights. Fuel can leak out and cause a fire not to mention damage to the environment. 2004 ext versions were recalled but not the ls why"?? in Wisconsin and when checking the internet found hundreds of complaints with the same issue. How long will it take before action is done with this problem? does someone need to die?"

Fuel sending unit stops sending correct information to the fuel gauge causing improper fuel level reading which lead to inadvertently running out of fuel in middle of the highway. Fuel gate will stay at 1/4 full the entire time. With a full tank of gas the gauge still reads 1/4 full. The operator has to guess how much gas is left in the tank.

  • 94,931 miles
I have a 2004 Trailblazer lt with 94,931 miles and am the original driver. The check engine light came on 2-3 years ago and I have taken to several different mechanics to diagnose with no success. In June 2010 I took into the local Chevy dealership for 100K service and was told I had a cracked fuel tank filler neck which I had to replace at a cost of ~$1000. This fixed the check engine light as well. Chevrolet is aware of this fuel tank issue and denies there is an issue with any model except 2002-2003 Trailblazer ext's and GMC Envoy XL models under tsb 05012. In reviewing the NHTSA website it is apparent the scope of this problem goes beyond these models. The local dealership advised they were aware the Trailblazer models had issues with the fuel tank but referred us to General Motors as there was no tsb from GM for this model. I spoke to 3 separate people at GM customer assistance who advised they would investigate and came back within 3 business days and denied any responsibility. I questioned GM about the numerous occurrences of cracked or corroded fuel tank filler neck issues and referenced the NHTSA website. They advised the NHTSA website, where many of these cases are documented, is not a GM recognized website for this type of issue and was essentially told they (GM) ignored complaints from this website. I was advised by the GM rep nothing else would be considered and when I asked for someone "higher" at GM to speak with was told they couldn't provide anymore information. When asked for the corporate address and CEO info I was told they wouldn't give that information out but I could look it up on the internet. Bottom line is Chevrolet does not stand behind their safety claims or vehicle issues and I feel compelled to have this documented on the NHTSA website.

1. there is no event that led to the failure, rather it is a crack at the gas tank neck, which is covered on document 07099A for the Chevrolet Trailblazer ext, however I have the Trailblazer lt which suffers from the same symptoms. 2. as it is a crack there is fuel leaking as well as fumes into the vehicle cabin. 3. GM does not want to cover the cost to fix the replacement of the fuel tank and labor as covered for the Trailblazer ext.

My gas tank always reads empty and the fuel light is always on. Occasionally after a fill up, it will appear that I have a small amount of gas, but soon returns to empty. For the last 6 months or more I have had to reset my mileage trip gauge every time I fill up and watch the mileage so I don't run out of gas. This is extremely inconvenient. Also, one night about 2 weeks ago, my speedometer was reading 20 miles an hour more than the speed we were traveling. Even after we stopped completely, the gauge read 20 mph. The next day it was once again normal and has been since, but this was very strange.

My 2004 Chevy Trailblazer will not accept gasoline. I had a 1/4 tank left and went to a gas station. To my surprise the vehicle would not let me fill the tank. I was first told that the vent might be dirty then a cylinder in the gas tanks system might have failed. The mechanic found a bulletin that said I had to replace the fuel tank filler upper pipe and lower hose because of vapors filling up inside. I paid for gas that ended up all over the ground instead of in my tank. I called the dealer to find out that a bulletin is different then a recall so they were not entitled to pay for it. I purchased in 2009 and GM knows about it but will not recall it. What if it explodes in the gas station from the vapors. Who's fault would it be then. I had no idea and would never buy a Chevy again. First I had a problem with the check engine light coming on when the gas cap was not put back on right and now I can't even get gas. What good is a vehicle if you can't use it. I am still paying for it. As soon as it paid for I will be trading it in. The dealer gave me a smo about a 3 year 36,000 mile warranty. When I bought it had 62,500 miles already on it. Why should I pay for something they knew was a problem but won't recall. Please recall this vehicle. In reading the bulletins for this vehicle I found that there are problems with the electrical system, the air bags, the fuel system, the transmission, speedometer, etc. How many problems do you need for one vehicle or are they waiting for someone to get killed over it. The bulletin says that a small amount of fuel may spit back out. Well that is a lie. All the fuel in the 1/4 tank spilled out on the ground and I paid for the gas I could not get in the tank. GM is no help, dealer is no help. The only one that was straight up with me was the mechanic. I am going to hate to see the bill for this one. My tax dollars at work. I agree why should we bail out the auto companies when they don't care what kind of vehicle they produce.
