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 breaks fail to work for a split second when the car hits a bump and brakes are applied. With the car slowing down and the brakes are applied, if I hit a bump, the brakes will stop slowing the car for about 0.5 seconds and the low traction light will blink.

Traction control on the Toyota Prius does not work properly. When traction is lost on a wheel, instead of transferring power to the other wheel, the traction control system completely disables power to both wheels for approximately 1/2 second. This is dangerous if you are trying to merge into traffic at an intersection and the road surface is anything other than dry asphalt or concrete. Fyi -tire condition is not a variable as the vehicle contains 4 winter tires with less than 200 miles of use. The tires are inflated per the recommendations on the door placard.

I have a Toyota Prius 2007 that has trac ( traction control). It has caused me to slide off the road and lose control on any slick surface. I have a patient who just totaled her Prius on an icy road and she had been having the same problems with loss of traction due to trac.

I was almost smashed by a snowplow today because my 2007 Toyota Prius' trac traction control removed all power from the front wheels thus bringing me to a dead stop in a busy intersection. This occurred on snow/ice. There is no excuse for losing power to the wheels even if they are spinning. The vehicle "sensed" that one wheel had spun and proceeded to progressively shut down power to the front wheels. I nearly wet my pants when this happened in front of an on-coming vdot snowplow. This was a near crash/death/injury incident. It happened over and over again all day. I search the internet later about it and found this: Toyota's response is at the bottom of the article. I think they are downplaying a bigger issue. A simple search on the internet and you can find story after story just like mine. Toyota needs to fix this.
