Filed May 30, 2018 · Electrical · 177,000 miles · TX · fire

One by one things have been going out and not working. First the car would not start all the time with the key, then the A/C stoped working, next was the fuel pump, then the injectors. I checked everything it could be. I was driving with my kids down the highway when my car just died lost power steering so it was hard to get off the road fast. I got it started and was driving and it did it again. I was able to finally get it home when it would not start again. After some research online found out this car has issues with the fuse box itself under the hood. I opened it up just to find the wording that connected the pins was broken in numerous places and had started to burn up in the box.

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.

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.

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.

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 way to fix it is to buy a new gas tank for $500.

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.

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.
