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.

2004 Chevrolet Avalanche Owner Comments

bought this used.. should have known, but 1 owner, great shape with light wear as for a 2004 goes. had it only a couple months when the engine light came on. had it checked by 2 different places with the little box thing they hook up. both said it was a sensor within the gas tank, maybe. said there were 2, one of which was bad. so had it replaced, light came back on, so they replaced it again, light cane right back on, so they replaced the other one, light is back on.. this time the auto lace took it all apart, checked everything, making sure the seals, pressure what ever else they look at is good. 2 days later, came back on.. so still have an engine light on, and no one can tell me why or get it to go off more than a week..

any ideas.. it doesn't stop here, but that'll be another issue.. :)
