My 20115 Leaf S is 3 weeks old with less than 700 miles.
I was descending an 8% grade hill in B mode with a sharp bend at the bottom. As I went to apply the brakes, the pedal went to the floor and B mode cut out. The car was now rolling down the hill and accelerating under gravity with no brakes and without B mode slowing the car. I was expecting to hit a brick wall at the bottom of the hill when suddenly, after no more than two seconds, the brakes and B mode came back on and I safely stopped. I was a bit shaken and felt very unsafe driving the car although the problem didn't recur and I haven't been able to reproduce the problem on similar grade hills. When I told my wife, she said that the day before she was going down a hill in B mode when B mode suddenly stopped working although the brakes were OK. B mode later came back on although she couldn't remember exactly when.
On reflection after the incident, it was as if the whole computer/electronics momentarily shut down and then rebooted. I didn't notice if the dash lights went off or not.
That was yesterday and today I took the car to the dealer today. After an hour or so I was introduced to a mechanic described as the only Leaf qualified mechanic they had. He said he had driven the car and there was no problem. I asked if he had driven the car in B mode downhill. Incredulously, he asked what B mode was! I asked if he had pulled the diagnostic codes and he said there was nothing recorded. I told the service manager this mechanic was not qualified to work on the car since he didn't know about B mode and they produced another mechanic who did know about B mode. We went for a test drive together but could not reproduce the problem. As the problem is intermittent, who knows when it could recur or with what consequences. The car is now with the dealer for further diagnostics.
I'll update this thread if I get anything useful from the dealer.
