“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 . …”
