While similar events were described four years ago at http://www.mynissanleaf.com/viewtopic.p ... 9&start=10
, my recent experiences have seriously upset my faith in the safety of EVs. I have owned and driven a 2014 Leaf 39000 Km over nearly four years, during which its quick and reliable acceleration had given me confidence in performing certain maneuvers, such as quickly merging into a traffic stream, or turning left through a gap in opposing traffic. Now I am experiencing occasional random total loss of torque during rapid acceleration, occurring usually one or two seconds after applying the increased power and lasting about a second, and sometimes repeating, then resuming full normal acceleration. I normally drive in Eco mode and often also in B mode. I live in eastern Canada with temperatures near freezing.
This is, as I said, occasional and random, and is hard to replicate. A dealer might never encounter it, so I am starting to take it seriously enough to try to analyse the circumstances when it does occur. I am also starting to drive more conservatively when in traffic (sort of spoils some of the fun of driving an EV).
Edit on Sun Feb 24, 2019 2:41 am:
Two months and two thousand kilometers later on the same car and driver this has not happened again!
So why it happened (about five times) last December is still a mystery. The last time was particularly bad as it occurred twice during the same acceleration while moving into a traffic stream ahead of another vehicle --- very upsetting at the time and leading me to post this notice the same day. I continue to drive more cautiously in traffic as a result.
