Dodge Journey

I do have one question for you all that have these. I notice when the wife starts hers up it has a loud whining noise, not pulley or belt, but a engine noise. Always on start up, Even when we bought it I thought it seemed kind of noisy. After its run for a few seconds it seems to quite down. Has anyone else noticed this.

Ours is very quit on start up, my sister-in-law also has a Journey (13) and no noise from it either.
