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.

Jan 31, 2011 - 2006 Scion Xb with appx. 38,000 miles stalled on the freeway at 65 mph with no apparent cause. I was able to safely coast down an exit ramp and waited appx. 5 minutes before restarting the car. It performed perfectly after that. After looking into it on the internet and realizing that I am not the only one who has experienced this problem, I have now contacted the dealership and am awaiting a response. No corrective action has been taken to date.

This is the second time my 2006 Scion Xb has accelerated when I stepped on the brake. This time it happened when I was going uphill about 30 miles an hour. When I stepped on the brake, the engine accelerated and began racing. I was able to brake to a stop, but the only way to get the engine to slow was to turn off the ignition and restart the car. As with the previous incident, it's impossible that I was accidentally stepping on the accelerator, since I used the brake to bring the car to a halt. It was scary the first time. It was scary this time too.

Engine: On Wednesday February 12, 2010 my 2006 Scion Xb, while driving on the freeway at approx 70mph. My engine shut off - no power - none!! no warning - just shut off!!! -while driving on the freeway. Aside from vehicles attempting to avoid hitting my vehicle and attempting to also avoid hitting others- I could have been killed and this complete engine failure while driving could have killed others as well. Of course I was over my warranty for this partcular coverage by approx 1,000 miles. Guess what the Toyota dealer took care of the issue, which they stated was the "crank sensor". they seeemed hesitant to fully provide an explanation, which of course I want and need as I am very hesitant to drive the vehicle. There has to be some sort of warning, you can't just be driving and have your engine shut off, engine won't turn-over, no steering, very little braking ability! I am very concerned, very - the warranty for this type of service was expired, although the car was repaired by the Toyota dealer service department and I appreciate this more than you know. I asked for answers and their lack of communication/information concerns me.
