Our LEAF went for its first service at the famous Fred Coupe last month, and while it was there I asked about the software update that Nissan had just released to fix the grabby brake issue. It couldn't be applied at the time due to some of their equipment being faulty, so it went back last week and the update was applied. I have to say it has fixed the issue. The car now stops smoothly and queueing in stop-start traffic is no longer embarrassing! It's certainly worthwhile calling into a dealer for the update if you have the grabby brakes problem.
