When the 12-volt battery failed on my 2015 Nissan Leaf, the car would still turn on and would move forward without pushing on the accelerator. The brakes did not work either. This happened to me both in a grocery store parking lot at night and then the next morning on a residential street. Similarly, when it turned the car on in my driveway, I put it in reverse, and the car moved without me pushing on the accelerator and the brakes did not engage when I pushed on them. The car behaved this way 4 times, including once for the Nissan dealership service worker who had to pull the car forward in the line of cars waiting to be serviced. After Nissan replaced the 12-volt battery, the problem disappeared. Several Leaf owners have told me to report the problem, because it is a safety concern that the car can move but the brakes do not work when the 12-volt is failing. I called Nissan to notify them of this problem but did not get a response beyond a call from consumer repairs saying she would make a note of it.

I didn't drive the car for a few days and the 12v battery died. So I disconnected it from the car and hooked it up to my 12v battery charger. When it was fully charged, I reconnected it and started the car. Both the yellow and red warning lights were on as were the brake, abs, and vdc lights. I started backing up in the driveway and as soon as I pressed the brakes, strange noises came from the front of the car. I slammed on the parking brake to stop. I tried backing again and noticed the brakes only engaged when the pedal was pressed almost all the way down. While troubleshooting, I noticed removing the vdc fuse stopped the sounds. Also the brakes are now usable, but require much more force on the pedal than normal. The trouble codes are c118a and c1a61. (abs e-driven int brake system brc-124 / brake motor power supply br-46) after an expensive diagnosis, the Nissan dealer determined "diag. Used consult. C1a61 current code motor power supply. Checked fuses ok. Electrically driven int brake unit harness and connections ok. 12v present to module. Brake unit internal shorted due to suspected surge. Rec replacing 12v battery and unit. Further testing may be needed. . . . . Estimate to replace 2817. 00 parts and labor. Part is from the factory. " I have seen many other Leaf owners write about this kind of problem and believe it may be a common defect. I also don't know why it wasn't covered under the warranty.
