I have a 2011 Nissan versa Hatchback, recently whenever I first start the car there is a single click sound coming from the brakes, at every stop and when I start driving again, there's that single click, it's driving me insane! I've read somewhere that it's the ABS doing a self check, but it never did it before, only after I recently have my brakes done, I've checked the brakes again, and they said everything is ok, why didn't it do it before? Who knows...good luck to you. By the way, you and I and many others are experiencing this, with all types of Nissans not only the Versas.
