84 owner complaints to NHTSA about the 2015 Nissan Leaf cite service brakes, 76% of all 110 complaints for this model year. NHTSA also lists 1 recall on this component.
“The electrically-driven intelligent brake unit failed on my 2015 Nissan Leaf. The brakes became inoperative: when pressing the brake pedal there is a loud compression/grinding noise and the pedal goes nearly to the floor with little braking force. The failure appeared suddenly after charging the vehicle; it had been working normally before. The vehicle had to be towed to a Nissan dealership. The dealer diagnosed codes U1000 and U110D stored in the ABS module for lost communication with the intelligent brake module, performed an inspection, and confirmed the intelligent brake unit failed. The dealer quoted $5,131.10 to replace the unit, which approaches the value of the vehicle. This is the same electrically-driven intelligent brake system that was the subject of safety recall 16V119000; the NHTSA VIN lookup shows zero unrepaired recalls for this vehicle, indicating the recall remedy was previously completed, yet the unit failed catastrophically anyway. This failure mode is widely reported by other Leaf owners. Loss of braking without warning is a serious safety risk. The vehicle and failed component are available for inspection at the dealership.”
“The contact owns a 2015 Nissan Leaf. The contact stated that while reversing at an undisclosed speed, the brakes failed to engage while the brake pedal was depressed. The brake and master warning lights were illuminated. The failure had occurred on several occasions; however, the contact stated that the vehicle recently failed to return to normal operation. The vehicle was taken to a dealer where it was diagnosed that the brake module booster needed to be replaced. The vehicle was not repaired. The contact researched and was made aware of NHTSA Campaign Number: 16V119000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was notified of the failure. The failure mileage was unknown.”
“The car was parked in a parking lot, and when we turned it on and pulled out of the space, the brake light, ABS light, and other warning lights came on and the brakes went soft. We pulled back into the space and tried again, thinking it was a fluke and heard a strange noise coming from the car when it started. Again the lights came on and the brakes did not work. We had it towed to our normal mechanic and then to the dealership when the mechanic was unable to figure out what was wrong. The brakes looked to be in good repair. The Nissan dealership was unable to reproduce the problem and found only old codes in the system. The codes listed on the receipt were FFD high key cycle counts, C118A, U1000 (ABS, EV/HEV), P3195, B29C1 However, after I saw similar complaints related to the battery in this car and told them about it, they found that the 12V battery was leaking. They replaced the battery and flushed the brake line to be safe, but did not charge us the diagnostic fee since they were unsure if they fully fixed the issue. I had recently felt like the brakes took more pressure than normal (all the way to the floor) to stop on the highway once recently and so did…”
“This is the third time my brakes have failed while driving, which seems to have something to do with the 12-volt battery. At least at first, I disconnected my 12-volt battery and reconnected it; this fixed the issue, at least for a while. The other day, I was driving down a road near my house and the brakes failed right before I came around a bend. I had to quickly press the e-brake to slow down, or I would have run right off the road. This is definitely a dangerous issue. Please issue a recall for this because I've noticed many other people complaining about the same issue—the same sound, feeling, and symptoms. It appears the brakes are malfunctioning due to a communication error, or a low voltage issue to the brake computer systems?”
“Was driving the car in a neighborhood setting only going 20 mph, ABS light turned on the dashboard, traction control light or some other light regarding traction came on as well, brakes failed. Had to use parking brake to stop the vehicle.”
“While driving normally, yellow brake warning lights came on but I arrived home without incident. Next time I drove, the warning lights were all off, but suddenly the brakes failed almost completely. I pushed the pedal to the floor and heard a grinding/clicking sound, and barely any stopping power. I was only going 25 mph, and was able to stop after 5 seconds of high foot pressure. At the same time, red brake warning light came on. I was able to get the car home very slowly, and strangely I had adequate braking power for the remainder of the short trip (although red and yellow brake warning lights remain on). I am happy to provide the car for inspection. This was extremely dangerous to the nearby pedestrians because I could not have stopped the vehicle had one been crossing in front of me. Had this happened at highway speeds, my passenger and I would have been in great danger, as would have other vehicles.”

Nissan North America, Inc. (Nissan) is recalling certain model year 2013-2015 LEAF vehicles manufactured November 19, 2012, to July 31, 2015. During very cold temperatures, the relay inside the electronic brake booster may freeze, requiring the driver to exert more effort to slow the vehicle down.
