OK, we're the proud owners of a new 2008 Prius, Pkg 6. We love everything about it. We have one question: My wife drove the car about 75' and began speaking with a neighbor for a few minutes. The car was idling during this time and, all of a sudden, there was a fairly large clunky noise. Is this a normal function? It hasn't happened since that time. Thanks a lot.
When the engine (ICE) has not fully warmed it tends to shudder when shutting down and starting up. This usually goes away after about 10 minutes of driving.
