noisy water pump on all the time?

It's not normal. Time to visit your dealer for warranty service.

 

You have the North America car so it could be the coolant heat storage (thermos) recovery pump, but I'm afraid I think it's more likely to be the brake accumulator pump. Get this checked out immediately.

If you're repeatedly braking hard, or the battery is very well charged, you could be using more friction braking than normal and it's having to run more often to build up the pressure.

 

Hi Super...,

A whiring sound is normal from the left front during the first few seconds after starting up, and then after turning the car off. But if it starts to surge and screech, then its time to go get the coolant heat recovery system pump changed. If you open the window and hear the sound coming out of the front of the left front wheel well, that is it.

You might be confusing the braking system hydraulic pump - this will pump on and off during driving. It also makes a soft whiring sound. This pump will be active especially if your doing allot of slow speed braking (below 7 mph) or are not maintaining a good following distance, and need to really punch the brakes, or are driving over rough surfaces (anti-lock brakes kick in and disable electric braking). Its common to hear the brake pump as soon as you put your foot on the brake, after the car has been sitting a while, before the car is even turned on.
