Any Nissan Leaf Owners having problems with brakes?

I have read that some people are having problems with Nissan Leaf brakes.

One owner said he noticed the braking assist displaying a mind of its own. He said sometimes he would just tap the pedal and the brakes would apply much more than the pressure he was applying. Other times the brakes would apply normally but then do not immediately release after they would stop pressing the brake pedal.

Also, is it true that the Nissan Leaf has an automatic braking feature on it?
