Brakes failed upon starting the car. Multiple warning lights on the dashboard (brake, ABS, traction control, and brake system) resulting in total brake failure - cannot stop the car with normal braking even while just putting the car into drive/reverse from park. Started happening ~3 weeks ago. The only thing that stops the car is the emergency / parking brake. If pressing the brake pedal all the way, just before hitting the floor there is a loud popping / grinding noise and the parking brake (?) engages. The first time, turning the car off/on fixed it. We took it to our local Nissan dealer, they said "could not find the issue in their system" and said it was a "fluke" and wouldn't happen again. Happened again a few days later and turning the car off/on didn't help, and the car was stuck in our driveway. Tried replacing the 12V battery, which fixed the issue temporarily. Happened again a few days after that and had to get it towed back to Nissan.* they found the issue in their system and think it's the "driven intelligent brake unit" and costs $2600+ to fix. They also say the "main engine harness" may need to be replaced for some reason as well, costing another $2400+. have contacted Nissan usa, they told me they don't have a record of this being a problem with Leafs (even though there are dozens of complaints on here) and refuses to provide assistance. This brake system is *extremely unsafe* for the driver & passengers, and everyone around it. My kids could have been near the car when it started moving on its own even though I was pushing the brake pedal. No one needs to die or get gravely injured because of this faulty system.

My car was parked in the driveway of my house. I turned it on like I do normally and I then I see the red brake warning indicator lights and the ABS warning indicator lights on the dashboard. I didn't think too much of it as I was rushing to get somewhere. My driveway is sloped down so when I put it on drive, I had to step on the brakes. I noticed it didn't work as I depressed it all the way down. Then I quickly used the emergency brakes since my car was slowly rolling down. My car is 3 years old, has about 35,000 miles and has never been in an accident. This was the first time this happened.

I was driving in somewhat heavy traffic in an urban setting at 25mph when, unexpectedly, I had great difficulty applying the brakes to stop at an intersection. It took considerable effort, including swerving, to avoid hitting the vehicle in front of me, and I pulled into a parking lot as soon as I was able, again having great trouble stopping. The loss of control of the brakes felt like I was skidding on snow or ice, despite the fact that it was a fairly warm August day. There was an accompanying loud, unpleasant sound coming from the brakes when I stomped on them. I had also noticed that a number of warning lights on the dash had come on all at the same time when the problem started. After coming to a complete stop in the parking lot, I turned the vehicle on and off many times, and each time, there was a low but clearly audible thrumming sound, plus a vibration I could feel in the brakes. The sound was particularly surprising to hear, given that the vehicle is otherwise an extremely quiet (100% electric) vehicle. After attempting to restart the vehicle about ten times, I decided to leave to wait for awhile before attempting to start it again. After about 20 min., I started the vehicle without trouble and cautiously drove it home on largely empty side-streets.
