Tl the contact owns a 2004 Chevrolet Trailblazer. The contact stated the he noticed a fuel odor emitting from underneath the driver's side of the vehicle. The contact also stated that the fuel mileage had also decreased when driving the vehicle. The contact took the vehicle to have an evap smoke test performed on his vehicle. The result of the test discovered that a crack had formed on the fuel neck that connects to the fuel tank, which was the cause of the failure. The contact then spoke with j. B. A. Chevrolet (7327 ritchie hwy, glen burnie, MD 21061) where he was informed that there were no recalls on the vehicle for the failure. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 126,432.
Two years ago check engine light came on. Code was gas cap. Replaced cap twice, no improvement. Mechanic then found small leak in neck of fuel tank. Rapid leak, worked fine for two years. Now, on December 7, 2010, check engine light on again. Found that fuel tank filler neck is broken and leaking again. Required a new fuel tank installed at cost of $750 +.
2004 Chevrolet Trailblazer lt leaking gas & fumes where filler neck joins tank. Have learned online that there are many people having the same problem. Dealer and gm will do nothing to help me pay for the repairs. I paid $1350. 00 to have a new gas tank installed. This must be a defect. I had my vehicle checked several times for the service engine soon light in the past. One occasion was the fuel cap and on another they could find no code. This should be covered. They know they have a problem. My extended warranty ran out 26 days before this happened. Thank you.
My wife's 2004 Trailblazer ext service engine soon light came on in late September 2009. She had been complaining of a gasoline smell after filling the vehicle. I had the obdii code read and it was code 0440 evaporative fuel system - small leak. I was told to replace the gas cap, and it did not remedy the problem. I then found out that the 2002-2004 Trailblazer ext had a known problem with the gas tank filler necks developing cracks and causing the ses light to come on and gas to leak when the tank is filled or near full. I contacted Chevrolet, who stated that out Trailblazer is not in the VIN range of Trailblazer ext's that were covered by a special notice that allowed the tanks to be replaced under a special extended warranty. The replacement cost is $900+. This is a known problem with 2004 Trailblazer ext, outside of the narrow VIN range that Chevrolet will admit to. All 2004 ext's should be included in the extended warranty. Our vehicle just turned 60,000 miles.
My 2004 Chevrolet Trailblazer 4wd has 41,000 miles on the odometer. Recently the service engine soon (ses) light became illuminated. Personal inspection of the vehicle revealed a small crack in the plastic fuel tank. The crack was located at the "weld" or joint where the plastic fuel fill pipe connects to the tank. This fill pipe also houses the fuel tank inlet check valve (icv). As my vehicle was past the three-year - 36,000 mile warranty period I attempted to glue the leaking crack. This held for a few weeks, the ses light went out and there was no odor or appearance of gasoline leaking from the area. Eventually, though, the leak returned, evidenced by the ses light illumination and gasoline leaking from the repaired area. Another repair attempt was made and is currently under observation. This exact problem appears to be detailed in general motors document id# 1985459; subject: special coverage adjustment - fuel tank inlet check valve fracture #07099 - (06/07/2007). This referenced document only pertains to 2002-2004 Chevrolet Trailblazer ext and GMC envoy xl, both longer wheelbase models than my standard LS model. Upon my discovery of this manufacturer known problem with this vehicle model, I took my Trailblazer to the local Chevrolet dealer today. The service consultant said he was not familiar with my problem and was unable to access the computer database for any relevant documents for my vehicle. He did take a copy of the above referenced special coverage adjustment document and promised a return call tomorrow.
Service engine soon light came on. Took it to auto zone and computer diagnosis was evap emission leak, small. Code:p0440. This happened twice over 2-3 week period. Replaced gas cap, that was not the problem. Light came back on. Took to dealership garage, I was told that I had a significant leak in my gas tank, at the filler neck, would cost $900 to fix it. Thing is, I had been driving this car around for over 3 weeks with my 2 small children in it with the possibility it could have caught on fire! how scary is that? dealership said it was not safe to drive due to possibility of catching fire. Contacted gm consumer service, awaiting their return call. They didn't seem interested in helping me. I know previous yrs (2002, 2003, and early 2004 models) have the same problem and was covered by gm or were recalled. I have never received a recall notice. I think it is suspicious that I have the same problem as previous yr models and I have only 85,000 miles on my car.
"service engine soon" light came on. Took it to dealership. Was told that the fuel cap was bad and there was a crack in the fuel tank. Replaced both parts costing $946. 73.
Around 50k miles the service engine light came on. I took the vehicle to the dealership. I was asked if I had recently got gas, when I replied yes, he told me to tighten the gas cap and the light would go if in a few days. The light did go off but the mechanic never documented anything about my visit. Several weeks later the service engine light came on again. Thinking that it was the same situation I tightened the gas cap and did not go back to the dealership. This time the service engine light did not go off. I took the vehicle to an independent garage to get it checked out and the result was a malfunction in the fuel system. Often times I smell gas vapors especially after fueling. Recently I was parked on a hill and gas was dripping from my tank. Local dealerships act as if they have never heard of the problem. My warranty has expired.
Check engine light came on three times within the first month and a half I owned the used 04 Trailblazer. It seems common from what most people posted on the internet that this problem occurs anywhere from 35 - 55k miles. The gas tank would constantly release an odor and I would get dizzy every time I drove the truck. I took it in to the dealer and they said it was just a leak in the gas cap and that it needed to be replaced. Once the warranty expired (one week later), the s. E. . Light came on again and the dealer service department stated that there was a crack in the neck of the tank and that it needed to be replaced. I picked it up today after it was replaced and totaled to $1,430. Gm knows about this problem and hopefully the letter that I have written to them will solve this issue and that I will either be reimbursed or compensated somehow for lost work and interest paid on this bill.
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.
The contact owns a 2004 Chevrolet Trailblazer. While driving at various speeds, the check engine light illuminated and the message center informed the contact to tighten the gas cap. When he attempted to tighten the gas cap, he noticed a thin crack in the filler neck. When he fills the gas tank, there was some leakage from the crack of the filler neck. The contact has taken the vehicle to the dealer, but it was not serviced because the warranty was expired. The current mileage was 34,000 and failure mileage was 33,000. Updated 04/22/08. The pipe to the gas tank was composed of plastic. It has a crack about 1/2 inches long at the gas cap area, thus allowing vapors to escape the tank. Updated.
2004 chevy Trailblazer. Gas leak where the filler neck connects to the tank. I have seen many, many of these on the forums. Gm has a bad design here.
I have a 2004 chevy Trailblazer and from day one I've had problems with gas overflowing out of my vehicle when pumping gas in to it. I'm not trying to top off the tank, at the first click I stop pumping and gas overflows outside of the vehicle all over my car, my feet and legs and the ground. Sometimes I don't even get the warning click that it's full. It doesn't do it all the time so when I've taken it to my dealership they say they can't duplicate the problem. I've met other Trailblazer owners at the pump and they say they have the same problem. This doesn't seem safe or environmentally sound. I have had the vehicle for 4 years and have tried many different gas stations/pumps.
When filling up with gas, it spews from the tank when gas nozzle is removed. It does not matter how much gas is in tank & happens even when tank is not being topped off. Also when filling, you must constantly reposition the nozzle because of gas build up in tank line will inadvertently cause pump to turn off. This has happened on numerous occasions, however last night was the final straw, Trailblazer had a quarter tank of gas, after pumping in less than a gallon, nozzle/pump started its clicking/auto shut off. I removed the nozzle to reposition it as usual & upon removal of nozzle gas sprayed (like spraying from a hose nozzle)from the tank as if under pressure. I was completely covered with gas from the waist down, I'm not talking about a light spray but soaked through my clothes to the skin with gas. Based on the amount of gas left on the ground I estimate that 2 or 3 gallons sprayed from the tank, the only way it was stopped was by putting the cap on. Although not seriously injured I am now covered in a rash from the gas from the waist down.
I have 2004 Trailblazer and I have had the gas line replaced and adjusted several time due to unable to fill up with gas and I again took it back now they want to replace the gas tank . This is an on going problem and the warranty has just went out and I am still having these problems it will work for a few months then it wont let you fill it up any more and I have to continue ta take it in.
The gas tank always overflowes when filled. It is hard to position the nozzle into the filler neck so that gas flows without holding the pump handle and repositioning several times during the filling process. The oveflow is not from trying to top off the tank either. It happens when the tank is not even full. I have had the vehicle into the dealership more than five times for this and for electrical/battery problems in less than one year. No correction has been made.
2004 Chevrolet Trailblazer fuel filler inlet overflows upon tank fill-up. This condition occurs at fill-up when pump handle is set on automatic shut off, or when shut off occurs when manually filling. This condition is repeatable, and happens regardless of what gas station is used. This condition was reported to a local Chevrolet dealer. Their fix was to replace the inlet filler hose to the tank. This fix was unsuccessful and the condition still exists. Currently attempting to schedule another service appointment.
Every time I fill up the gas tank (tried 10 different pumps at 10 different gas stations) the autoshut off on the gas pump does not work quick enough. Gas overflows out of the tank and spills on the ground. Something wrong with the design of the Trailblazers fill up tube? I am not trying to "top off" the tank either.
I purchased a 2004 chevy Trailblazer in September 2003. Within 6 months of purchase, the check engine light came on. Dealer said it was a computer error and reset the computer. Approximately every 6 months thereafter, check engine light came on and dealer said each time it was evaporation caused by not tightening gas cap appropriately. Dealership changed owners and new dealer reset the computer once (saying gas cap not tightened appropriately), the second time found a hole in hose that comes out of the gas tank and repaired it. Upon the third time with new dealer occurring 12/01/2010, we are told there is a crack in the nipple of the gas tank and want to replace the gas tank. I feel recourse from the manufacturer is due since obviously the problem existed upon purchase of the new vehicle.
