After closing driver's power window, the window motor sounds like it's not quite finished the job, if you hit the up button on driver's window again, the window motor still makes whirring noise for a second, you can repeat this up to 10 times before window motor stops making noise. Minor annoyance, but none of the other 3 power windows do this. Dealer says everything checks OK, had it checked twice. They say it's normal. I say it's not normal if the other 3 windows don't do it.
