general problems of the 2016 Nissan Leaf

On Friday, November 1, at about 3 pm, the brakes failed pulling away from the curb in a forward direction after loading equipment into the vehicle. Really stomping the brakes as though they had a fluid problem did get them to engage. I think the problem occured again backing out of my driveway prior to Monday the 4th when I fixed the problem. Again, really slamming the brake peddle got the brake to engage. You may look at the vehicle if you wish. On Friday, I was at a large senior center party and there were many pedestrian with limited mobility near the exit. An out of control vehicle could have been very dangerous. I applied experience from internal combustion engine (ice) vehicles with brake problems and that fortunately worked, but brake fluid was not the problem and there is no clear documentation of the problem in the owner's manual. This problem is an ev problem. I can't really take the vehicle to the dealership because they have failed to perform warranty service and refused to do so in the time required by MD law. To determine the cause of the problem, I checked the brake fluid level which was normal, brake wear, which was little, checked the owners manual in detail (nothing clearly stated) and then searched the internet. By Monday the 4th, I had seem a reditt post that said a dead cell in the 12-volt battery could cause a confusion in the vehicle between the regenerative braking system and the hydrolic braking system. There had been some odd behavior at startup. The dash info would flash up with missing numbers then come on normally. And, at shutdown a few time, the lights left on buzzer would sound even though the lights were off. I checked the 12-volt battery voltage and it was low, about 10 volts consistent with a bad cell. I ordered a napa battery said to fit the vehicle, and replaced the defective battey which seems to have fixed the problem. The napa store confirmed a bad cell in the old battery. No clear warnings of the problem showed.

Drove home at 7pm mild day (65-70 degrees). Stopped the car and turned it off for an hour. Had to leave home at 8pm. Turned on the car and backed up the driveway. Tried to stop but break wasn't working. . Pressed all the way that abs started trickling. Used the hand break to stop the car. Turned off the car and turned it back on. This is when I noticed all the dashboard lights are on including break and abs and had the same break not working issue. . Pulled the car into the driveway slowly and turned it off till tomorrow morning. . Started the car tomorrow morning and everything was back to normal and driving without an issue.

The Nissan Leaf was being driven on a 35 mph road in a hilly area. While going approximately 25 mph on a downhill curve coming up to a red light the driver applied the brakes and they did not engage with normal pressure. The driver then pushed the brake peddle all the way down to the floor before the vehicle begin to slowly stop causing the vehicle to go 10 feet past a red light into an intersection. The driver drove out of the intersection and tested the brakes again with the same results. The drivers spouse arrived to test the vehicle and verified the same results. The only way home was a very steep down hill so tow truck was called to pick up the vehicle and bring it to the Nissan dealership the tow truck driver also verified the brakes were not engaging when he loaded the vehicle on the flatbed. When the vehicle arrived at the dealership and unloaded from the tow truck the brakes started working. The dealership tested the vehicle and verified the brakes passed inspection. Feeling unsafe to drive the vehicle the owner tried to convince the dealership to test more. They were not able to reproduce the issue. The owners reported to Nissan of America customer service. Nissan of America said they had not heard of this type of issue and that if the dealership couldn't find anything there was nothing they could do. Since the dealership and corporate can not fix the car and do not want to further investigate the vehicle was towed to the owners house where it now sits unused.

No brakes at startup. No previous problems. Drove 20 miles night before. Brake pedal went to floor while backing out of garage.

Brake stopped working while I was driving on san thomas expressway in santa clara city in California; I immediately switched to "park" and also used manual brake, eventually I managed to stop it; since it's blocking a lane, police came and towed the car to the dealership. Mileage is estimate since the car is still being repaired in the dealership.

I haven't had an accident due to the brakes not working, but I have had similar issues that others are reporting. I've learned to not follow close at all. Mine is only at low speeds that I've noticed the lack of brakes. Seems random, cannot determine a specific speed or conditions that are common. It has happened since the beginning. Only at 13700 miles currently.

My 2016 Leaf sl was damaged in a fairly low speed collision during heavy office rush traffic (around 7:30am in the morning). When the car in front of me suddenly stopped, I also braked hard. At that time I heard abs like sound but the car did not actually stop, it kept on going and hit the car in front of me. I was too stressed out at the moment therefore I did not have time to think. Later on, I spent some time searching internet with search queries like 'Nissan Leaf brake problem' or 'Nissan Leaf did not brake' etc. I found multiple mentions of experiences very similar to mine. If you perform google search, you will see what I mean. Is there a way to look at the Leaf onboard data to see what may have happened?.

Car lost all break capabilities as I approached a traffic light. Brake pedal was loose and car would not engage breaks, loud crack sound on first pump before break was lost. Since I was going at low speed (30mph) I could employ manual break to stop vehicle. Break remain in failure state till on hour later when it seem to have returned.
