I was driving 35 mph on at least 4 seperate occassions when my I applied my brakes, they completely failed. I took it back to Toyota and they kept it for 10 days, flushed the brake lines 4 times, replaced the master cylinder, charged me $600 and made me sign a form saying the van was unsafe to drive because they have no idea what was wrong with it.

I drive about 5,000 miles a year, in the beginning of 2012 I was told my brakes did not pass the state inspection. At this time I had around 20000 miles on the van. The reason of the reject was rust on the rotors, it was so bad and the rotors were so thin and of a poor metal, they could even be worked on. I had to replace the rotors and pads on all 4 wheels.

During a recent trip to Alabama from Virginia, our 2008 Toyota Sienna suddenly accelerated while pressing the brake pedal instead of braking. Both times, we were approaching moderately heavy traffic. My wife went to apply the brakes to slow the van. Instead of braking and slowing the vehicle, the van went into full acceleration mode. The transmission downshifted and started applying full throttle. The first time we thought we were going crazy. The second time, both my wife and I watched as her foot applied the brakes and to our amazement, the van started accelerating again! luckily both times, my wife took her foot off the brake pedal and reapplied once the van stopped accelerating and the brakes worked then. I haven't had time to take this into the Toyota dealer yet. We are still under a 30 day warranty with carmax, so I have communication out to them to see how we should handle this situation. I thought this Toyota sudden acceleration story was exaggerated. Now I've experienced it myself.

Could not stop after my ABS brakes locked up then were soft/absent, drove up on the center median, got back on the road attempting to go around the car infront on the right side couldn't due to other traffic then went back to the left got back up on the median. My passenger side front bumper corner went under the other driver's driver's side rear bumper corner lifting her car up into the air causing it to fall on top of the passenger side of my hood and front right fender crushing them, resulting in over 10000 dollars damage. No one was seriously hurt and neither car's airbags deployed.

On day of the accident, it was snowing and road conditions were icy and slippery. As vehicle was going around the bend, driver noticed cars were stopped at a signal. Driver could not stop vehicle in time to avoid a crash since ABS brakes locked all the wheels and the car was sliding and so driver swerved to avoid crashing into other cars and hit a tree head-on. Vehicle sustained front-end damage. Air bags did not deploy.
