Three problems related to other fuel system tank mounting have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
Was smelling gas inside and outside of car. Upon inspection discovered the gas tank is leaking. Reading recalls discovered gm is only replacing tanks on vehicles made at certain factories and only in certain geographical areas. With the amount of vehicles affected gm should have to replace them all without discrimination. This vehicle has been nothing but a money pit for me and has been the worse car I ever owned based on repairs required to keep it going.
I just gased the Chevrolet Trailblazer and was driving down the road and we could smell gas did not think much of it because we just got gas then the check engine light came on it was a po442 code evaporative emission control small leak detected so I have been smelling gas off and on and keep getting the po442 code. So I go buy a vent valve solenoid and put it on clear the code I notice gas around the intake pipe on the gas tank so I take a closer look and its broke half way around the filler neck and this is a recall on certain VIN #s but mine is not included in this recall I think it should be when you are dealing with fuel and the amount of fuel that can leak out this can be a fire hazard for sure I think gm needs to step up and take care of this problem on all vehicles that have this problem instead of picking an choosing certain VIN #s.
I own a 2004 chevy Trailblazer. I purchased it used from a dealer in December of 2010. I notice since I have owned it that there is something wrong with the gas gauge. It will show a decent amount of gas in the tank then by the time I get out of my driveway it is showing empty. It will go up and down all the time. I know I am not out of gas, because I make sure to put gas in every day because I am not sure what is in the tank because of this problem. I was going to take it to a machanic to have them look at it and fix the problem. Since seeing that an investigation is being done for the same exact problem, I decided to write here first. I am requesting that the years investigated also included 2004, since it is the same problem that is being investigated by your agency.
