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

problem #1

Mar 012004

Sienna 6-cyl

  • Automatic transmission
  • 39,000 miles


Failure code P1155 "air fuel sensor failure" at 40K miles $282 for just the sensor. The vehicle is less than 3 years old no help offered from the dealer with cost of repair. From my research on various bullitens, I find that Toyota has had numerous problems with thier sensors. The part number of my faulty part 89467-41040. I own two 2001 Toyota vehicles and all service oil changes provided at dealer ships. I had two GM's and because I had my service provided at the dealer they took care of things like this out to 50K miles. Attitude like this will push me back to GM next time. I think it's about time to swap back because I am upset with Toyota's attitude!
