Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

My check engine light came on. After linking to the computer I had a code # P0442. After I, and my mechanic inspected the vehicle, we found that the gas tank was cracked and leaking. I had to replace the faulty gas tank, for an expensive fee. I called Chevy, and to sum it up, I was left to work this problem out on my own, with no financial help from GM.

Service engine light came on. My private mechanic found it to be code P0440 indicating the fuel evaporation system had a problem. Initial inspection found nothing but upon performing a smoke test of the fuel system, the fuel inlet nozzle on the fuel tank was found leaking. Only fix was to replace the tank. Total cost was $2200. I notified GM and was told they cannot do anything since the vehicle is out of warranty. Fuel tanks should not be leaking, especially when they are only 4 years of age. Many other similar complaints on this website show this to be a common problem with this vehicle. A recall to check all fuel tanks should be done before someone is killed over this poor design/quality issue.

2003 Chevrolet Trailblazers 3-4 weeks ago my service engine soon light came on and I took it to the dealership who showed me a leak at the junction of the gas tank and the hose from where you fill up the tank. The service man tightened the clamp. The light came on again and I took the TB back and was told the connection was cracked and that the tank had to be replaced. I haven't been in an accident, haven't run over anything etc to cause this. I am having the tank replaced--
