interesting tid bit on the prius stalling problem

I found this on yahoo forum prius-2G
It is a story I never read before and thought I would bring it to this forum to kick it around. Anybody have any comments?

Last night on the way home from work, my wife's Prius just died. She
had a fully charged battery on her screen, which suddenly went to
zero. The dashboard was showing a large red triangle with
exclaimation mark and a red car image appeared in the upper left hand
corner of her data screen. The bottom line is that a vital switch,
which is located at the bottom of the transmission, became shorted out
with water. The "fix" for this issue, according to Joseph's Airport
Toyota, was to "pack the switch with grease". According to JAT, the
car is "fixed", but I'm concerned about what will happen as soon as
the grease deteriorates. Clearly, according to Toyota, the switch
should not have been exposed to the weather. It should have been
enclosed or housed in some way. They also confided that this problem
is and has been the number one problem with Prius cars dying on the
road, suddenly. In my experience, this switch seems to be the only
weak link in the engineering of this automobile, but, due to the
dangers of the car stopping suddenly, it should be a recalled item
with a more permanent fix than a glob of grease.

anybody know where this switch is located and can it be waterproofed with silicone?
Thanks for your input.
