    All,

    Does your Prius v make a servo or motor noise when you approach the driver's door and unlock it via the smart key (no key, touch only).

    My car makes the noise for at least 5 seconds and it is coming from the drivers side engine compartment. It only does it the first time I approach. It doesn't do it if I reenact the approach a second time and unlock.

    Not a problem, I'm just curious.

    It's the brake accumulator pump. The Prius uses an electrically powered brake booster, which it charges in anticipation of your use.

    Even freakier is I noticed one day I came into my garage after a few hours I think it was and the car was making some very strange sounds--not the servo one. I looked into it around here and found out that it was also normal.

    That's the Prius language . . . Prius-ese . . . but some don't realize that it's their Prius talking to them. Soon there'll be a TV show about it. The Prius whisperer.

    LOL - thanks for the laugh!

    I have also noticed this noise and good to see confirmation that it's all normal for a prius. Have the car for less than a month now and noticed it the first week, but I assumed it was normal.
