| Power Train problems |
The car stopped responding to accelerator pedal and eventually stopped in the middle of the road just before a hill. Haven't noticed any error messages and instrument panels seemed normal. Switched off power and then turned on again, the car worked normally. I am going to bring the car to a service center but it seems hard to find an appointment.
Car goes into turtle mode, losing all power. Has happened a few times, each time has been coming off a highway or heading up a steep hill and then travelling at low speeds. When car is turned off and on, codes reset. I have a reader for the obd, it is showing fault p2138 000a ev/ hec acc pedal pos sens 1,2, err evc-196. As power is completely lost, this could easily cause an accident. Once reset the car acts like normal. Every instance has happend with a battery state of charge of over 30%.
My 2015 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. 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.
