During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.

As you come to a complete stop or go under 5 MPH, the vehicle's oil gauge will go all the way down. Once you accelerate, the oil gauge goes back to normal. When pumping gas into the vehicle, the gas pump will reset as if the gas tank is full but the gauge shows it's half empty.

I own a 2004 chevrolet trailblazer ext and just like the thousands of others mine has a defective gas tank filler on the top of the tank. It's a known bad part feom the factory. Mine has had a hole for a while now. It can literally leak over 10 gallons of gas a day if you fill the tank to full. Even if you don't the smell of gas in and around the vehicle is terrible. My check engine light is on because of it. It runs like crap because of it. What's more dangerous than spilling gas everywhere you go!? Some people have had chevy pay for the repairs on there 2004 trailblazer. Look it shouldn't matter what your VIN# is or how many miles at this point (I just hit 150,000) the gas tanks on these vehicles are faulty, they're dangerous, they're exspensive. I surely dont have $800-$1500 laying around to fix a part that is known and proven to be bad. We all know tbey are bad, chevrolet knows it, the federal safety agency knows it. The kicker is you cant even find used gas tanks for these things to save money. Every single one is junk or already replaced one that was junk. It is completely crazy that the owners of these vehicles where never probably taken care of in regards to this issue with the gas tanks
