So I had a code 36 error pop-up on me about two weeks ago, I got all the cables but I haven't had time to hook it and get screenshots yet. I noticed after charging it up to about 75% then riding it down to about 60%, I put it away. A few days later I checked it and the battery was down to around 35%. I thought maybe I was wrong and had actually ridden it down that far, but mis-remembered. I did the same thing the other day, this time after riding it down to 25%, I made sure that I charged it exactly to the halfway bar. I just checked and it's down to 35% again. They key was not in it at all during those times. Has this happened to anyone, or is this typical of a code 36 error? This all started happening after a code 37 showed up after the winter, if that has anything to do with it.
