I got in my 2012 to go to work but the ready light wouldn't light. Acted like my foot wasn't on brake.
Took my ICE to work. I was concerned about Leaf's reliability.
Thanks to the posts here and other topics I was able to troubleshoot my issue.
First I tried a reboot / reset by disconnecting the negative cable. While I was waiting the 10 minutes I measured the 12v battery. Got about 9 volts. Tried to charge it but the needle gauge on charger was erratic. I put the cable back on and tried to start but now got a Can't find the key fob message.
12 v battery is no good. It's failure is not common. Normally one can charge a weak 12 volt back up to 12 volts. How long it holds the charge determines how quickly it needs to be replaced. This one was partially fried. Getting a jump was impossible.
Next day go to AutoZone and buy the best one they got. Duralast Gold with 5 year . Ended up getting a $20 rebate.
The guy at AutoZone gave me a funny look when I wanted a 12v battery for my electric car.
Installed it in the Leaf without any issues. So nice that the terminals are not all corroded in the Leaf.
Runs great now. I swear I'm getting better range.
