Hi,

I bought 07 Prius package #5. I have drive about 50 miles and runs great.
I have noticed that on regular interval the battery makes a noise (like a trrrrrrrrrrrrrrrrrrrr) for 1-2 secs or so and then goes away. Mostly it happens when I apply brakes, I drive for few minutes without applying brakes and then apply the brakes I would hear that noise for 1-2 secs. I checked with the service department, but they say it is normal. It is hard to belive if that is the case. Does anyone hear such noise. It does annoy me.

-Thanks

Sachin
