cazort:

I can't give you any "official" explanation, but my 03' has always done this in the 5.5 years that I've had it.

It's normal. Don't worry about it.

I'm not 100% sure, but I have always assumed the fan is cooling the electric motor after the car stops, and there is no air flow from the moving car, to avoid damage to the motor windings. I would let it run and shut off on its own.

Hope you like the car. I know I've been VERY happy, even though my IMA light is starting to come on at 172K.

One of the best investments I ever made...
