I don't own one yet (I'll be getting the Hybrid when I do), but from everyone's description of the problem, I can't imagine that the engineers designed it to work the way it does. Something is wrong.
I would agree. Buyers of cars are well informed about cars and how they should drive etc. It would seem to me very unlikely that the engineers at Toyota would 'design' a car with a problem like this, when the news of a problem can be spread so fast among owners to see if the problem is common or not. As this problem is so obvious to some owners, there should be prompt response from Toyota. Class action law suits, safety actions, bad publicity, can be very expensive as we all know (for lots of different kinds of products). This is not the kind of problem like the Takada airbags where no one new until years after the faulty airbags were installed, How much did that cost??? Keep reporting and providing information to the buying public.
