Yesterday, while pulling away from a light, my 07 Prius lurched as if the
brakes had been put on, had no acceleration, and several dash lights came on
(Red triangle with an exclamation point in it, the check engine light, the
yellow circle with an exclaimation point in it, and the VSC light).  No
brake warning light was on.  From a stop, it took over a mile to reach 45
MPH.  The gas engine was running but the gas pedal had no effect on
aceleration, though the engine was reving quite high.  After having sat for
2 hours in 50 degree air, the car ran and accelerated normally, though all
the dash lights were still on except for the the yellow circle with an
exclaimation point in it, and the VSC light.

Any ideas what this is about?

When I started the car after sitting overnight in 45 degree air, there were
no warning lights on and the car drove normally.  I took it to the dealer.
they were able to down load 2 trouble codes, both with an un named component
in the hybrid system.  but since the car had no problems when they saw it,
they couldn't fix anything - Toyota wouldn't let them return an expensive
part that was not "defective".  Now I am left with driving the car till it
breaks again.  Fault codes aren't enouh - What a system - Thank you Toyota!

The dealer wasn't very forthcoming, saying only that it was a very expensive
part of the hybrid system and was covered under warenty.  When it breaks
again, I'll fill everyone in.
