One problem related to brake loud noise has been reported for the 2013 Nissan Leaf. The most recently reported issues are listed below.
The issue: from parked and powered off I apply the foot brake and power on - put in gear (forward or reverse) and go - apply brakes and there isn't any (as in none) - panic - push pedal harder while panicking - pedal rapidly pulses as it sinks several inches to the floor boards and all four tires suddenly lock-up and the car skids. All the while making a loud noise that shakes the car and sounds like a drywall screw gun that has sunk the screw all the way in. Every warning light on the dash lights up (all of them). I had this issue several times 11 months ago and took it into the dealership. The second time I brought it in the issue was somehow resolved however the dealer said they couldn't find a problem. Now a year later it's happening again.
