I am looking for some guidance. I have a 2011 leaf and it's in good condition. It was running well but then it suddenly stopped responding one day. I remember seeing 12 miles left on the battery. I thought the car was out of juice, so I charged it overnight. But there was no lights on , no beeping and dashboard/console seems dead. The car doesn't respond to remote keys. I have to manually unlock the car. I left it alone for couple days, and gave it another try but no luck at all. The car seems totally dead. I looked at the battery and charging port cables connected to the battery. I couldn't spot any issue or wear/tear.
Any suggestions on what's going on and what should I do ?
