S, like i said, battery was at 4 volts and i had to jump it to start it [my first EV/EV jump] i had to jump it two more times that day then i got a new battery, however, the 'old' battery was only a month old. as another data point, i did need to fill up one tire several times as it had a slow leak, carmax also fixed that, but i might have been using the 12 volt too much?

What model LEAF did you buy? S, SV or SL? What symptoms have you had?
