Toyota has plenty of failures but sudden acceleration isn't one of them. I do thank that scare for letting me buy a Prius really cheap though.
I would have gone with engine sludge.
Vehicles affected include:

The Tacama truck frame recall was also quite notable, but I was thinking of more recent examples.
I am also very convinced that there was in fact a sudden acceleration problem. Some people died, just like the GM ignition.
