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.

2001 Toyota Sienna Owner Comments

Sienna 6-cyl

  • Automatic transmission
  • 54,525 miles


At 54,525 miles, the check engine light came on. It was diagnosed as "replace air/fuel sensor B1 S1." Failure caused excessive damage because the sensor fused into the rear exhaust manifold. Diagnostic testing $ $49 sensor replacement part $227.52 " " labor $150 rear exhaust manifold $154.21 rear exhaust manifold gasket $29.27 repair was not done at a Toyota dealership. I am reporting this so that Toyota will change the design. Failed part should not damage surrounding structures. Suggest recall on this part if Toyota continues to use this design.
