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.

2007 Toyota Prius Owner Comments

problem #1

Mar 182007


  • Automatic transmission
  • 8,983 miles


Cause: Flat tire in the front left or front right of the vehicle. The front left demonstrating the most severe hazard failure: The traction control system engages regularly due to a discrepancy between the spare and normal tire size. Traction control cuts power to the drive wheels and cannot be overridden, causing vehicle to lose speed in non-deterministic manner. Vehicle is not responsive. Condition is worst during the first 40 miles driven on the spare tire but consequently improves due to learning inside the car computer. Unfortunately, vehicle is most dangerous when the driver has the least control over the situation. Correction: None, the manufacturer claims the vehicle is operating as designed.
