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.

What owners say
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.
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.
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.
I started having problems with the fuel gauge swinging between full and empty then my check engine light came on. I've been told that I need an whole new fuel pump assembly and that the fuel tank will have to be dropped to replace it. I've been just setting the trip meter and filling it up every 250 miles because the fuel gauge now just stays lit on empty all the time. I don't have any problems with it running, starting, etc. So I'm assuming that it's just the sensor that is out. 2006 chevrolet trailblazer ext.
On several occasion over the past year my fuel gauge in my 2004 chevrolet trailblazer lt has read inaccurately leading to breaking down due to the vehicle running out of gas while the gauge was still reading at least 1/4 tank moments before the engine stalls. On all occasions I was driving on the freeway the gauge showed 1/4 tank and then all od a suddenly dropped to e with the fuel warning light coming one. Within a few miles of this sudden drop and the warning light coming on the engine would stall due the vehicle being out of gas. I have complained to my local dealer on several occasions and all they have offered to me is to replace the sending unit, which in this model is integrated with the fuel pump at the cost of almost $800. This seem wrong to me. Now that I have read that this seems to be a problem on these types of vehicles I am even more upset that the local dealership told me my issue is an isolated issue and they have never heard of any problems with the fuel gauges in these vehicles.
Erratic fuel level readings on fuel gate. Once this started it was regular and would read full, empty, partially full regardless of actual fuel level. Replaced fuel pump module and level sensor. Old part is not still available. I am reporting this because I heard there is an investigation I had a 2006 chevrolet trailblazer extended 2wd we had no safety issues as we discovered it was not working and monitored miles driven to prevent running out of fuel.
The fuel gauge on our 2006 chevy trailblazer has failed along with the check engine light coming on resulting from numerous codes. The entire fuel pump/filter/sending unit has to be replaced and the vehicle wont pass and inspection without it. Gm needs to recall this vehicle for this problem and refund owners who have spent money fixing the problem.
Like thousands of other owners (since this happens to the gmc envoy too, so it's not just a chevy issue), one day the gas gauge works fine, the next it reads empty after filling it up. However, as a bonus, the friendly check engine light now comes on randomly to let me know the fuel gauge isn't working. I've had the codes read by two different places and this is the only error recorded. I now have to use the trip meter to "guess" when the truck needs filling up. Since it's going to cost me several hundred dollars I don't have to fix it, I'll just have to live with the inconvenience. In massachusetts, like many other states, they do an emissions test by plugging into the vehicle's computer. Well, since the check engine light has come on at some point, the computer says "not ready" and the vehicle fails the test. You have to wait until the light goes off and then drive about a week before the computer resets itself. However, without fail, the light always comes back on just before taking it back to get re-inspected, thus resetting the whole process. I've had this happen for the last 3 weeks in a row regardless of number of days/miles driven. Another week and another tank of gas wasted. So, in order to get the car to pass inspection, I either have to get real lucky with the check engine light or have the repair made. Since this issue prevents the vehicle from passing the state inspection, it should be considered a safety/emissions concern and all vehicles recalled to repair the combination fuel pump/sending unit. If gm doesn't consider this a concern and recall the vehicles for this repair, then they need to have the vehicles recalled to have the check engine light stop coming on so the vehicles can pass state inspections.
Own a 2006 chevrolet trail blazer. Have run out of gas three times because the gas gauge does not read. The car is full of gas, but the gauge still reads empty. Have run out of gas on main roads and caused traffic jams. Will cost over $1000 to repair the fuel pump.
