Extended warranty fuel tank filler leak known issue with Chevrolet which affects other parts such fuel pump, fuel module, etc Chevrolet has been aware of this issue since 2007 and I just got a call from a senior advisor from Chevy stating that the "replacement part" is not going to be in until April.I find this unacceptable since I am driving around with a gas leak. The sa first started off, well we understand you are complaining about the part being back ordered. No I am mad because if they sent out letters to consumers, don't you think you should have the part in to fix the issues with the Trailblazer" Chevy is dragging its feet to fix its own warranty that it extended to consumers. The longer I drive around with this leak, the longer others parts such the fuel pump, fuel module, etc will fail and Chevy should cover these parts also. How does Chevy expect me to drive around for 5 months with a fuel leak"

Fuel tank has tiny crack at the where the tank is welded together and gasonilne and or gasoline vapors leak out causing the check engine light to come on. GM has issued special coverage warranty for vehicles that have up TO150,000 miles or 15yrs old whichever comes first. Vehicle has 160,000 miles on it and they will not pay for repairs that should actually be a recall since it is a safety issue that is affecting millions of vehicles

Code 440, smell of gas on different occasions from the gas tank area. Replaced gas cap & purge valve. Smell continues. Not sure what is factor for the smell, yet it has gotten stronger. A few times I have smelled the gas while driving, , tho, most times it is upon exiting the vehicle it is most notable.

On August 26, 2015 we purchased a 2003 Chevrolet Trailblazer from wali's auto sales in enola, pa. It had 93,907 miles on it and appeared to be in good condition with a clean car fax. We traded in our 1996 Chevrolet Suburban and received $1700 in trade in value purchasing the Trailblazer for $5722.70 including tax and transfer fees. Brakes and ball joints had been replaced prior to our purchase along with a transmission line. We took the vehicle for an alignment as soon as we purchased it. We drove the vehicle approximately 200 miles and then on September 17th left home with intentions of driving the vehicle to stowe Vermont. At 11:30 am on the morning of September 17th (approximately 2 hours into our trip) the vehicle lost power and brakes close to scranton, pa. The engine caught fire and within 7 minutes the vehicle burned up. The VIN number was not readable. The scranton fire department responded along with Pennsylvania state police and the forty fort police. We have a copy of the fire report. The vehicle was towed by a local tow company. My wife and I escaped injury. We had liability insurance through state farm which covered towing and fire company expenses. Wali's gave us a 30 day warranty on the vehicle and has acknowledged since the incident that there is a warranty on the vehicle but is not forthcoming in allowing us to submit a claim to their insurance company.

I bought a used 2003 Chevy Trailblazer 6cylinder 4W with those156000. Well shortly after buying it I had my windows rolled down in a drive thru and smelt gas. I didn't think much of it until a few weeks later I noticed that I had a leak of some sort and it had the gas smell but within another week my gas mileage per tank of fuel went down drastically and I noticed I had puddles under my vehicle instead of a few drips now. The smell of gas is overwhlming it gives me headaches when I drive. I'm afraid it's going to start a fire. It constantly drips gas now when I ddrive you can seexa trail leading to me. I wish I nevercwould have bought it. It's so unsafe for my children with glad leaking out.

I have filed a prior complaint and the number is #10695487. I contacted General Motors and have never been treated so terrible in my life. The person on the phone told me to either take it to a dealer ( with no help from GM to check it) or get over it and hung up. I am still having the fuel leaking and with no help from GM I will not be able to fix it. I would like to have it fixed because in my mind it is a defect on GM part and they do not want to own up to it. Please help with this issue.

I have a 2003 Chevy Trailblazer and it started to have the smell of gas and a dip from the fuel tank. I was wondering if this was a fix that would be covered by General Motors. I have only owned this vehicle a year and live on a very limited income. I love this vehicle and do not want to have to part with it but I need a vehicle to go to doctors and hospitals for medical issues. Please help in getting this fixed.

Gas has been spilling off the gas tank metal flange where the intake hose attaches too. Chevrolet dealer does not recognize this as a recall. Apparently a fatality needs to be directly link to this problem before this issue is address.

Service engine light illuminated due to leak in evac system according to diagnostic test. Dealership confirmed leak to be at weld where fill spout tube is attached to fuel tank. Strong gasoline fumes were present coming from the vehicle. I was informed that the fuel tank would have to be replaced at cost of $1300. Internet research revealed that GM had a tsb addressing this problem (campaign #05012), but it only applied to ext models. Since this is, in reality, a fire safety issue, I believe GM should also include all models with the same problem regardless of age or mileage.

Trailblazer

Put vehicle in park and stayed in drive. Shut vehicle off and put on park however still in drive and now will not start. Since I work on vehicles I looked at transmission linkage and found cable came off transmission linkage. Plastic clip broken. Looked on line and found transmission shifter cable repair clip for $14.99. Since it was special order I went to dealer and was told there is no repair kit and that they have plenty of shifter cables in stock $75 went ahead and ordered aftermarket part special order 2 days and today 3 days later was told out of stock and none available til December. Coincidence or is this a common problem? I'm afraid someone will not know or realize vehicle still in drive when shifter moves to park and not moving shifter linkage at transmission.
