2013 NISSAN LEAF with 24000.0 miles

I charged the Leaf the night before and went downtown. It was winter in maine and around 10 degrees. After going into a store and coming out when i started the car and put it in d the brakes didn't work. I slammed the pedal down to the ground but it didn't seem to do much. I almost hit the parked car in front of me but i put the emergency brake down and luckily stopped. I turned the car on and off but the problem was still happening. The brakes made a weird clicking and electronic noise. I turned the car off for about 5 minutes to call aaa and when i turned it back on it worked. I've done some research and this has happened to other owners. There was a voluntary recall (P5327?) which was already done on the vehicle but this still happened. My Leafspy app showed the dtc codes of C118A 0109 abs e-driven int brake system brc-124 and C1A61 0109 brake motor power supply br-46. I took it to the dealership and they said that power wasn't being supplied to the brakes. Dangerous! They did not really have a fix for it other then put in a $2300 part and then do more tests.

2013 NISSAN LEAF with 29000.0 miles

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.
