    I wouldn't doubt it. Who knows how many production changes have been made since the third generation Prius was introduced over a year ago.

    Over the years I have bought early production automobiles and discovered that numerous "under the hood" production improvements were made in the several following years even though the vehicle appeared nearly identical over a several year period. After that experience with several automobiles, I vowed never to buy another early production automobile.

    I wonder if the change is a response to these problems with stuck parking lock:

    Regular cars have a manual lock override.

    BTW, what is a silicon type vs mechanical type? Semiconductor vs electrical one?

    I have no idea, this terminology is used by techdoc. My understanding is that they replaced the transistor/thyristor circuit with the standard coil and contacts relay. There is also some software change for instrument panel to display additional message instead of a simple beep code - "N" shift lever position related.
