Has a bad gas smell leaking gas somewhere

The federal safety agency action number : pe07014 occurred on my vehicle around november 2014. The problem presented as p0442 cel and odor of gas after parking in garage. Gm has indicated because the special consideration allowance has expired, despite the low mileage they will do nothing. This vehicle was purchased new in august 2003. I do not understand why gm was not compelled to issue a safety recall due to the risk of gas leaking. I would appreciate assistance to get gm to minimally provide defective parts replacement, due to the know manufacturing defect in the gas tank.

This is my second complaint due to a second problem with the fuel system. Vehicle was taken to dealership for gas leak, which turned out to be caused by 2 different, well-known fuel system problems. Gm offered no solution to either problem because I'm 3 months outside of the extended warranty. My total bill for both leaks was $1,500. Both leaks are known safety problems, as referenced in bulletins 07099 and 07076. I was told the vehicle should not be driven because of the leaks. Gas tank replacement is not what I consider normal a maintenance item. It is a known problem and these tanks need to be recalled.

Fuel leak on top of fuel tank. This is a known safety issue, and an extended service/warranty was added to fix this problem. The dealership said the vehicle should not be driven as-is. I did not receive notice of this warranty. Gm refuses to offer any more than a 10% discount, even though 3 months prior this same defect would have been fixed at no cost under the special warranty coverage. I was willing to split the cost 50/50, but no other options were deemed acceptable by gm. My vehicle is under the 120,000 mile cutoff as specified in the extended service, but 3 months out of date. Being this is a known problem and severe fire hazard, I feel gm should offer a better solution and at the minimum a reduced cost repair.

In the past 3 years vehicle had gas odor upon exiting vehicle upon use. Until recently, fuel started leaking profusely when vehicle was running. General motors issued extended warranty due to many complaints regarding this issue. We being the original owner of the vehicle were never sent any information regarding the extension of any factory warranty regarding this issue. After contacting general motors about this issue, they stated that the vehicle is beyond the year and mileage of the extended warranty. If we would of been notified by gm about this problem with leaking fuel tanks we would of resolved this issue when we started smelling the fumes a few years back when the extended warranty would of been in effect. After contacting gm and speaking with a representative, they refused to honor the warranty. Gm neglected to contact and inform us of any extended warranty that applied to our vehicle regarding this issue. We feel that this problem with the fuel tank is a safety issue that could be a potential fire hazard causing serious injury to anyone inside or around the vehicle. We are going to file a written complaint with general motors. Please let me know how you feel about this situation. Thank you.

I began smelling gas from the vehicle and noted that there is gas dripping from around the gas tank. I contacted my mechanic and was told that this is the third trailblazer he has seen in 2 weeks with the same problem. Chevrolet advises that there was a fix which was good only until 120,000 miles. How am I supposed to know to take it and have it fixed before 120,000 miles if I am not notified by gm? This obviously is a serious safety issue involving the trailblazer which gm is aware of but has thus far resisted recalling.

Due to a service engine soon warning light and smelling gas inside my vehicle, I took my vehicle to my local mechanic. He stated there was a crack in the neck of my fuel tank. The tank needs to be replaced. He also stated that this is a common problem with trailblazers. I looked up any recalls. Found special coverage adjustment - fuel tank inlet check valve fracture#07099a. I called a local dealer who confirmed that was right. However my VIN # does not fall under VIN #'s listed. The dealer called a local gm rep. And I was offered 40% covered by gm meaning I would have to cover the other 60%. I do not understand why only some VIN#'s are in this and not all of them. It seems that this a problem that is very common in these trailblazers. I do not feel safe driving my family of 5 around in this trailblazer with a fracture fuel tank inlet check valve and the strong smell of gas in the truck and risk of fire from gas leaking out. This should be a recall item so that those of us that have trailblazers not with in the VIN #'s covered can get this fixed and be safe. Chevrolet/gm should step up and make this a recall this is a huge safety issue.

I have a 2003 chevrolet trailblazer ext. On 03/07/2013 it started to leak fuel while parked in the garage, I took it to beardmore chevrolet in bellevue,nebraska to have it checked out. Service writer told me there have been problems with the fuel tank filler neck cracking and leaking along with the fuel pump leaking and pooling fuel on top of the tank, they informed me that gm had a service letter out that covered full replacement of tank,pump and lines at no charge for 10years or 150,000 miles, I have 81260 miles and an in service date of 03/26/03 so I was 10 days out of warranty on the repair. Dealer called gm for me and got approval to repair the trailblazer with me paying 500.00 of the 2200.00 repair. I took the deal as they could have just denied the whole claim. So people if you smell fuel of have a wet fuel tank get it to the dealer asap. Gm helping with the bill is better than nothing. I was also told the new parts were all updated and I should not have the problem again.
