general problems of the 1998 Toyota Sienna

What happened to the prius in California the same did happen to us back in 1999 with our Toyota Sienna van. My wife was driving on I-5 in oregon. She pressed the gas pedal to overtake a car and then when she pressed the brake to slow down the brakes didn't work. She drove into the hwy median fence to stop the car. When we contacted Toyota, they didn't admit any fault with their car (the same what they are doing now) and told us it was our fault that we do not know how to use their brakes. We have several cars but we didn't have a problem with other cars. I didn't buy a Toyota after that crash but I am also worried who else the part supplier has been supplying parts to.
