I purchased a 2005 Prius about 1.5 months ago. I love the car. But it seems that when I first turn it on and drive a short distance after the gas engine has started and then turns off I can feel it. It is like a bit of a slight shudder in the engine. Is this normal?

That is normal operation...

Without having a technical explaination to back me up, I find that the car usually only shudders upon ICE shutdown when the vehicle is just warming up or hasn't been running very long. As soon as it has run a while I find that ICE shutdown is a lot smoother, but it is always noticeable

Actually, without any form of "ICE" running light indication it is difficult to know just when the ICE is operating. The "MFD" only gives a partial indication and it's difficult to observe. I believe the "ICE" operating light would have been the best and first modification Coastal Dave should have persued.

I've noticed this also... particularly the first in-operation shutdown after starting up in the morning. Anyone know why?

It's just cold. The engine shuts down much more smoothly after break-in and when the engine's warmer.

I've noticed the same thing when the ICE is cold (isn't ice suppose to be cold?? ) I notice this at the first red light I reach. The motor is running, and then kind of "jumps" around in what seems like an attempt to shut down. Sometimes I can feel it "jerking" around like it wants to shut down, and then smooths out as if it decided it would rather be running.

Once the ICE is warmed up, this does not seem to be a problem.

I agree though; a light indicating the ICE is running is way too important. Coastal Dave has been teasing us for way to long with his "teaser" page showing the device!
