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 NHTSA 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

Let me begin with stating that my 2004 Trailblazer has had its service engine soon (ses) light on for well over a year due to a large evap leak (code P0455). As a result, I have taken it to two mechanics, had the purge solenoid valve replaced twice, had a plethora of smoke tests and all other tests done, with no resolve. I received a letter from GM (dated a year before) just a couple weeks ago stating that "some 2004 model year Chevrolet Trailblazer vehicles may contain a fuel tank inlet check valve (icv) that could fracture.. a fractured icv could allow fuel vapors to pass through and droplets of fuel to accumulate on the side of the fuel tank". the letter goes on to describe that GM will repair the icv if the condition occurs within 15 years the vehicle was originally placed in service or 150,000 miles, whichever comes first. My Trailblazer has been in service for 12 years, however I just passed 155,000 miles. Had I been notified around the time the letter was supposed to arrive, I could have easily taken my Trailblazer to the dealership and had this repair done with no qualms. However, because I have passed the 150,000 mile mark, GM refuses to cover this repair. This is extremely upsetting considering the obvious safety risk presented with "droplets of fuel accumulating on the side of the fuel tank". when speaking to a GM representative this morning, I was told to take my car to a dealership and this would be an out-of-pocket expense. Considering the safety issue, I want my Trailblazer to be repaired and covered by GM as it should be for all Trailblazer and Envoy owners with this problem.

My vehicle is in the GM special coverage adjustment program number 07099 and is under the GM spl coverage pgm update 14423. I was notified that the icv could fracture and create an 'engine service soon' light. That light was activated in February. I took it in, it's the icv. They said they'd replace the fuel tank as soon as they could get parts. They still don't have the replacement -- and say it could be may or June. Meanwhile the 'check engine' light could be on for icv -- or it could be another problem. With dripping fuel out in the open, it's a safety hazard -can't be used on a trip and can't be sold/traded as it's defective.

In 2014 I noticed a strong odor of gasoline on a regular basis coming from my 2004 Chevy Trailblazer. I had my local garage look at it and was told the fuel tank assembly was compromised and needed to be replaced. Mileage at the time of repair was 124,000 and cost was almost $800 parts & labor. Looking online I noticed many other owners of the same make/model dealing with this issue.
