I bought my 2016 Leaf back in May. Had a trouble free summer and fall. In the last few weeks since the weather turned cold I have had the same issue twice. In both cases I had been driving using accessories, heater, wipers, lights. Parked, turned car off, returned shortly and when starting got warning lights, brake and red main warning light. Had the green "go" but car would not shift out of park. Brake pedal went to floor. In the first instance I was able, after several attempts, to get the car into gear at which point the brakes required a lot of pressure but did eventually work. I checked, and the brake fluid was low, at the min mark. Topped it up and still initially had warning lights/poor pedal response, but lights went out when I started driving and brakes went back to normal. Had it checked at the dealer, no problem with braking system. The second incident was this week. I had been driving with heater, heated steering, heated seats, and radio on, stopped to pick up my mail, and when I got back in the car and turned it on I had a repeat of the first experience. Got out, checked brake fluid, it was fine. Walked around the car a couple of times, got back in, started up, all was normal. Taking it to the dealer tomorrow, but my dealer doesn't have a lot of Leaf experience so would like to get some feedback on this forum. I'm hoping it's a battery issue, less expensive! What say you?
