Recently reported FUEL SYSTEM, GASOLINE problems on 2003 Chevrolet TrailBlazer EXT

Nhtsa 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. *tr

Ses light came on. dealership had no apps brought to mechanic. code was for fuel emission leak. replace gas cap. week later code ses came on again. brought back to the mechanic, said fuel tank is cracked. called chevy and was told there was a recall but not my vin..... *tr

There is a strong odor of gasoline vapors coming from the rear of the vehicle, a crack can be seen in the neck of the fuel tank. when filling the vehicle, fuel spills out of the tank from the crack. the fuel gauge cluster in the dash doesn't work. the blower on the a/c unit doesn't work on the highest (5) level. also, the fan clutch went out causing the car to overheat severely. the fan does not engage, causing the water pump shaft to become damaged. also, the rear driver side window quit functioning, despite buying an expensive new regulator and replacing it. having researched the issues, i find that i am among hundreds, possibly thousands of unsatisfied people with the same problems. *tr

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. *tr

Where the gas filler neck connects to the gad tank this area develops a crack allowing gas to leak from the vehicle and during filling up to a couple quarts of gas can run onto cement by the pump, also strong gas smell in the garage.. this also triggers the check motor light. according to internet postings other trail blazer owners are experiencing the same problem. *tr

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. *tr

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. *tr

Tl* the contact owns a 2003 chevrolet trailblazer ext. the contact stated there was a massive fuel leak coming from under the vehicle. the contact noticed the leak as the vehicle was idling. the contact turned the vehicle off and had it towed to the dealer. the contact stated that the vehicle was at the dealer but he had not spoken with the dealer to determine the diagnosis of the failure. the manufacturer was notified who advised that when the dealer inspected the vehicle, then they would contact him. the contact filed a complaint with the manufacturer. the vin was unknown. the failure mileage was 185,000. the consumer stated the fuel tank, fuel mount, and fuel lines were all replaced for $2000.00. if the vehicle had set on fire it would have exploded under the driver's seat. updated 08/20/2012 *js

Had to replace fuel tank because filler neck cracked due to being brittle had to replace fuel pump due to top rusting out and causing a gas leak i received a large bill to replace these parts and expected them to last longer then 8 years. *tr

I have a 2003 chevy trailblazer ext the fuel pump module has started to corrode, i knew something was wrong because of the strong odor of gasoline inside the vehicle and further investigation showed a leak of gas also.this is in addition to our gas gauge not working for the last 3 years. upon talking to multiple rep's, gm claims they sent out letters in 2007 alerting the consumer to a potential problem. i am the second owner of this vehicle. i purchased this vehicle in september 2005. gm stated that letters do get lost in the mail, when i stated we were not made aware of this situation. i was never informed of this potential hazard waiting to happen. gm claims the service bulletin had parameters of 10 years or a 120, 000 miles which ever comes first. i have been in contact with the rep several times, and have not been successful. i do have 149,000 plus miles on this vehicle. i took the truck to the local dealership, they were claiming nothing has ever been documented on this type of vehicle. this is when i did my own research and found the service bulletin as mentioned above and the complaints of this same problem all through the internet blogs. it seems we are not getting anywhere and would appreciate some condsideration from gm and taking part of the responsibility for this problem. we had our children in this car when the gas was leaking out, what if it would have caught on fire? i would like to contact our regional representative for gm. *tr

I have a fuel line leak and my husband got on-line and saw that there is possibly going to be a recall. i called chevy and the guy told me that there is a possibility of "special coverage" for this. he asked me my mileage and the vin number then put me on hold. then he came back on line and told me that my trailblazer was 10,000 miles over the limit for the coverage. i think this is ridiculous. it's only 7 yrs. old and i don't think that mileage should have anything to do with it. it's a safety hazard and i have 3 children that are passengers in this vehicle. so therefore i have no vehicle until this is fixed and the cost is so outrageous that i have no idea when i'll be able to get it fixed and i have no way of getting myself to and from work and i'm going to have to try to rely on other people to take me to and from places. i think this problem should have absolutely nothing to do with mileage of a vehicle and that chevy should fix this. i have read on-line of alot people having the same issue with their trailblazer. *tr

I, along with many others are experiencing major problems with the instrument panels on our chevrolet trailblazer. my mother traded hers in because her speedometer was going out. but my problem is much worse, my whole entire dashboard is out. my gas gauge doesn't work, my speedometer doesn't work, my oil pressure doesn't work, my thermostat doesn't work, nothing works. my cruise control acts up too. *tr

Fuel smell inside and outside of vehicle. *tr

I have a 2003 chevrolet trailblazer ext and it has started to smell like gas is leaking. after some research on the internet i have found this is more common in these vehicles than i would of thought. i have contacted my local dealer and a part is being ordered, but i would like to make sure that it will be at no cost to me to have this repaired. i understand it can fall under a special policy adjustment or tsb# 05012. this is a big safety hazard and would like to know that someone is making sure this is fixed so that a leak will not put any families at risk. *tr

I own a 2003 chevy trailblazer xlt, when i fill the tank up and park on a hill the tank leaks gas out from the top of the tank or the top of the cup that connects to and goes into the tank. i have a steep driveway and now i notice that i leak gas when i am on a full tank and parked on a steep hill...i have 3 boys ranging from 2, 4 and 14 and they all smelled and saw the gas. *tr

the service engine light was coming on and we had diagnostic done and was told that it was the gas cap. we replaced several time. everytime i drove or rode in my vehicle i smelled gas and i would get a horrible headache. my husband took my vehicle to get an emission test done we were told the fuel tank was cracked at the neck and leaking gas. we had it repaired nov 6, 2009 after we had been told of this. the shop that repaired my vehicle said they were shocked it had not caught on fire. there was evidence this had been going on for a while. probably when we were told the gas cap was loose is when it started, and that had been over a year before. *tr

Re: special policy adjustment-fuel tank inlet check valve fracture #05012. about 2 weeks ago i started to smell gasoline in a very strong way in my 2003 chevy trailblazer ext and had this checked out and was told that my gasoline tank neck was cracked. this apparently is a recall but i was told my vehicle had too many miles and would not receive a new gas tank. i have 3 children and the smell was very overwhelming this has to present some type of danger while driving. my vehicle is no longer under warranty and my auto mechanic can obtain a gas tank from a dealership for $600. the total cost of repair is $800. is it possible to receive some type of reimbursement for this clear and present danger from a defect that is not my fault? *tr thank you, denise randall

I am filing a complaint against the 2003 chevrolet trailblazer. i took my car into the mechanic because to see why the service engine light was on. he stated in that is was the evap system, meaning gases are leaking from my car. he stated in that its a common problem on these models because the hose attached to my gas tank causes the rim to crack and gas leaks through the crack everytime i fill up my car. i inquired having it fixed. in some many words he stated the only thing i could do is to replace the gas tank, but part (the hose) has not been modified from the original, so basically i will have the same problem. he showed me where the gas tank was moist from gas leaking. i am fortunate to have not been in an accident yet. however just to know that i have gas leaking from my car is enough to have me concerned. i would appreciate if someone can look into this problem. thanks *tr

I am the owner of a 2003 chevrolet trailblazer ext, i purchased the vehicle new from gm. in the last year my ses light has been coming on, i took my vehicle to an auto parts store and they analyzed my vehicle to read the code causing the ses light to come on. i had a leak in my fuel tank emissions system. they recommended i replace my fuel cap to fix the problem. over the past year and after replacing the fuel cap, the problem would go away for a month or so and they reoccur. i took my vehicle in for a system check of the fuel system. my mechanic performed a smoke test on the fuel system, they told me they found a fracture on a weld with the fuel tank, furthermore they said there was problems with the chevrolet trailblazers with faulty welds on the fuel tank. i searched the internet and found auto forum board stating gm has known about this problem for a while. talking with a co-worker about my problem, he stated he owned a 2003 trailblazer and recalled receiving a notice from gm about this problem, he gave me a copy of his notice where the notice talks about fracture of a weld on the fuel tank and chevrolet providing owners with an extension of repairs for 10 years of ownership or 150,000 miles. i never received a notice from chevrolet about this program. i called the chevrolet customer assistance center, where i told them what happened with my vehicle; i also told them i had 167,000 mile on my vehicle. they told me they first needed to verify the crack by a gm dealership mechanic. they also told me i had to pay for the fuel system to be check and there might be some consideration for them to pay for the repair if it was indeed a crack in the fuel system. the crack was confirmed by the chevrolet dealer, but they told me since my vehicle had over 150,000 miles they would not pay for the repair of my vehicle. the fuel tank is a static system, it should not wear out, i feel gm designed a faulty product and should repair this crack at their cost. please help me. *tr

Check engine light came on at approximately 56,000 miles, diagnostic check was performed by the dealer. findings: gas vapor pouring from the seal, corrosion and moisture. need to replace the gas tank. *tr

Smell of gas developed around vehicle at all times. had it looked at and nothing was found. brought it to another shop and they dropped out the fuel tank, finding the top of the tank wet with fuel and the connection rusted. the solution was to replace the fuel pump and parts. *tr

About a month ago i started to smell gas vapors when i drove my car. one day i was on the highway and a person next to me honked his horn and told me that he saw gas leaking under my car. i was near pep boys and pulled in the parking lot. i shut my car off and looked underneath it. i saw a lot of gas dripping from under my fuel tank and falling onto the ground. i went inside pep boys and told them the problem. it was nearly closing time so i left the car overnight and called for a ride home. pep boys called me the next morning and gave me an estimate of $270 just to drop the tank and look at what may have caused the leak. they said it was likely a bad fuel pump or bad fuel lines. i asked them another estimate on how much it would cost to fix my gas leak. they said it would cost around $600 to $800 to fix my car if the fuel pump or bad fuel lines were really the problem. i told them to not work on the car and said that i would pick it up. so i towed the car back home and pulled it into the garage. this is the first time that my car has leaked gas. the next day i took off the fuel tank to check where the leak was coming from. when i looked at the top of the tank, the fuel pump was corroded and there was gas on the outside of the pump. also when i took the tank off, the filler neck hose was cracked and was not connected to the gas tank. i called a junk yard and ordered a fuel pump for $150. i also called my local dealer and told them my issue. they said that my car had too many miles on it and was not covered by warranty anymore. since the dealer could not help me, i called general motors customer service and issued a safety defect on my vehicle. they said that there was a extended special coverage on my vehicle that might cover the repair. i called another dealership and i am waiting for them to call me back. right now my car has been in the garage for almost a month. the only ...

Tl*the contact owns a 2003 chevrolet trailblazer ext. the contact stated that whenever the vehicle is filled with fuel, the sensor that indicates the tank is full fails to work. as a result, gasoline overflows and leaks from the tank outside of the vehicle. since december of 2008, the vehicle has been repaired four times, which included a fuel tank assembly and tank replacement. the vin was unknown. the current and failure mileages were 55,000.

I have intermittent smell of fuel coming from vehicle; consistently declining mpg; ses light coming on; taken it to the dealership after having received a letter stating that there was a fuel tank or pump issue; they diagnosed that the filler neck was cracked a nd leaking but stated that it wasn't part of the repairs from the letter and said it would cost a $1000 to replace my fuel tnk and then they would replace the fuel pump module for free. *tr

Began to smell fuel from the rear of my 2003 trailblazer ext. i had received a letter from gm stating the filler neck some times cracks and would be fixed without cost. i took the vehicle to my dealer, they dropped the tank and said the fuel module was corroded and they would replace the tank but want 625.00 dollars to replace the fuel module. and will not release my vehicle. i told them to put it back the way it was and they said they can't. *tr

Strong gas fumes and check engine light comes on -reads an evap code. *tr

2003 trailblazer ext, began to have strong odor of gasoline after operation. no signs of visible gas noted under vehicle. problem persisted, (approx 1 month) and gasoline became obvious in liquid form dripping from bottom of tank and framing of vehicle. vehicle taken to local mechanic and fuelpump/modulator changed and problem resolved. *tr

I filled my gas tank on my 2003 chevy trailblazer ext. and got a gas smell, shortly after the check engine light came on. there is a leak in the fill and fuel pump area i guess. i was referred to see if there were any recalls for this defect and came across this. the garage did a temp. repair with silicon that only lasted 3 weeks. now the same thing is happening. i would have to change the entire gas tank to fix this issue. *tr

I detected a strong gas smell and took the truck to be repaired. i was informed that the fuel pump module was leaking due to being rusted out. i took it to the dealership (jeff wyler). they agreed to cover the repair of the gas tank and the labor (due to a special warranty due to other fuel leak problems), but would not cover the cost ( $454 + tax) which was the part that was the cause of the problem. the assembly of this part is unpainted medal and rusts very easily (most other company use plastic assembles to prevent this very problem). the location of this part makes it almost impossible to wash, in order to remove any salt or other corrosive elements. i do not see a way that i could have prevented the rusting of this part. i believe this is a design defect that chevy should have to correct, due to the fact that it could have very easily cause a fire to the vehicle due to the amount of fuel/vapor leaking. *tr

I have a 2003 trailblazer with 73,000 miles on it. just recently we are smelling gas fumes really bad to the point it makes us sick and is also hard to deal with one car having to be dropped off at work, etc. i have 3 children and have parked the vehicle because number 1, i feel like this is a big safety hazard for my children and number 2, i cannot afford to repair this after reading all the comments on the internet ($900.-$1000. to repair). it sounds like there are a lot of people dealing with the same thing. can you tell me where to go with this situation? am i suppose to contact gm, and if so are they doing anything about this problem? thanks, sandy nosker *tr

I recently had my fuel tank replace now i hear knocking and i understand that the fuel pump have been damage because of this. gmc needs to look into this as a recall. *tr

Fuel leak. *tr

Fuel system fuel pump module had corrosion and leaked gas, had to replace.

Several times happening in the outside vicinity of my vehicle i could smell gasoline. took my vehicle to the dealer and described my problem to them and expressed my safety concerns about the gas smell. they advised me my vehicle should not be driven until they could inspect and diagnose the nature of the gasoline smell. dealer inspected and found the fuel sending unit and line to be corroded on top of the gas tank and it was leaking fuel onto the tank. dealer in process of replacing fuel sending unit with a new unit. cost of repair quoted at $840 dollars. dealer gave me a discounted quote "to help make things right" of around $340. vehicle is a 2003 chevy trailblazer with 65,000 miles. seems unacceptable to me for a 4 year old vehicle to develop a problem of this nature. *tr

I have a 2003 trailblazer ext. just got it from my in-laws, only 21k miles on it. gasoline vents on the ground when filling the tank full. the check engine light remains illuminated. i counted more than 20 complaints just like mine on the nhtsa complaint list. example odi id numbers are 10191706, 10190967, 10188345, 10187405, 10186556, 10185694, 10184336, 10183773, 10182724, 10182384, etc. i assume it is a cracked filler neck. i called gm customer service. they seemed helpful and gave me a case number, but advised me to go to a gm dealer for an official diagnosis before they can proceed with helping me further. no promises at this time. i assume i'll have to pay for the diagnosis. this is a dangerous malfunction, it causes fumes, odors, and puddles of gasoline beneath hot vehicles. *tr

I have a 2003 chevrolet trailblazer ext. the "service engine soon" light came on. i took it in to a chevrolet dealership. it was found that the gas tank was leaking gas and the tank would not hold pressure thus causing the light to come on. the tank was leaking where the filler neck attaches to the tank. the dealership service director stated that the the crack was clearly a defect and was not caused by damage or misuse. because the vehicle was out of warranty he stated the repair would be at my expense and would be approximately $750-$800.00. i phoned chevrolet customer assistance and filed a complaint. after they communicated with the chevrolet district service rep. they concluded that gm warranty would not pay for the repairs, even despite the danger and liability involved. they did suggest that if the dealership would approve, to have them do it at the dealership cost. the gm customer assistance rep stated that my only other form of arbitration was through the better business bureau. as of this date the repairs have not been made. i have found quite a number of trailblazer owners on the internet who have had the same problem and have had to pay to have the repair made out of pocket.
