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 Toyota Sienna all wheel drives have a suspension or drivetrain issue that causes tires to wear to chords on inside edges in 10 to 15,000 miles.vehicle came with runflat, bridgestones br380runflats and dealer replaced at 9,000 miles due to severe wear with2256017dunlops, now at 28,000 no tread left inner, and require replacement again after 9 months of driving obviou sly problem is not the manufacter of tire but something in deseign of truck or AWD system, Toyota should recall, this issue cost approx1400.00 in tires for one set and apparently will only last a year, Toyota should be accountable for this tire wear issue issue and either retrfit vehicle a suspension drivetrain fix that will not wear tires, it should be noted that I have 2 of the same vehicle with exact same problem, on both Toyota replaced the 1st set of tires at under 11,000 miles and basically said too bad it's not Toyota problem by the time 2nd set were worn 10,00 mies later.
