I noticed the braking defect soon after taking delivery of my Leaf. Similarly to the other respondents, the continuance to braking after the pedal has been released occurs at any speed and without warning. I have had it happen at parking lot speeds, on the freeway, and at all speeds in between. I have been unable to discern any particular situation that seems to 'cause' the phenomenon. I have expressed my concern about this to two separate Nissan dealership service representatives (at downtown Nissan of los angeles, and universal city Nissan) who both said it was the first they'd heard of the problem. Neither seemed inclined to look into my claim in any way. The fact that a serious freeway collision has been reported along with several other less serious occurrences detailing the same problem indicates that there is indeed a problem. Is Nissan waiting for people to be killed because of this before they do something about it? I really love the car, except for this braking problem, but I really hate Nissan for ignoring something potentially life threatening until someone is seriously injured or killed.

While braking lightly and not sudden to turn into a shopping center, the Leaf applied full brakes and did not release the brakes until the car was going about 10 mph.

I was on the freeway traveling appropriately 65 mph. The vehicle to the right and in front of me suddenly swerved in to my lane and braked hard in front of me. With no place to go on either side of me, I was forced to brake fast and hard. The ABS kicked in as expected but once I had decelerated to a point where I knew a collision was not imminent and took my foot off the brake, the car continued breaking very hard. It took the better part of a second with my foot now completely off the brake before the brakes actually released. In this time, the car behind me was not able to stop and hit me hard, causing injury to two people in the car who were not belted in. This accident would have been avoidable if the Leaf had not failed to decrease the braking effort when I released pressure and then ultimately took my foot completely off the brake pedal. It felt as if something like the brake assist function was malfunctioning...

When driving at 60 mph down the freeway, I hit the brakes hard to avoid a collision with the car in front of me. I decelerated to about 30mph while veering to the right to avoid hitting the other car. To inform the rapidly approaching car behind me, I tapped my brakes about 4-5 times a second to flash my taillights. At that point the brakes locked up and my car rapidly decelerated even though I had removed my foot from the brake pedal. After about 1/3-1/2 second, the brakes released and I was able to regain control of the car and continue driving. After checking online forums and my local ev group, it turns out that two other people have experienced similar braking behavior where the car decelerated rapidly even though the brake pedal was not pressed.
