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.

My brand new Toyota Sienna has produced hum noise at around 2500 RPM as soon as I pickup the new van. I have the dealer and the regional reps looked at and they found the noise and they also told me that all the Toyota with the same engine have the same problem. I was told they will not fix it. I filed multiple complaints with Toyota but received the same result! I like to know if you can do anything about it. Thanks! *updated 12/12/07 updated 12/12/07
