Hi all, I'm at my wits end with my new Nissan Leaf that I had delivered in May 2020. Within a few days I was getting 'Key System Fault' error messages, which occasionally would prevent me from putting the car into gear. Over the months I've also had 'Service EV System, No Power' (despite having full charge), which wouldn't let me put into gear or turn off the car, 'System Malfunction' and 'System Fault'. It's been into the Nissan dealership four times, each time they didn't know what to do so had to have Nissan Technical advising - one time they replaced the main CPU, the most recent time they replaced the door locking system. Supposedly they can never replicate the faults when they have it in the dealership, yet as soon as I get the car back the faults are straight back. Nissan Technical have supposedly never seen this issue other than a car in Europe which was solved with the door locking system replacement (which hasn't worked on mine). Other than the 'Service EV System, No Power', you can usually clear the faults by pressing OK but it comes up pretty much daily, meaning there's obviously an issue somewhere. They're intermittent, don't always happen on the second+ trip of the day, most often first thing in the morning but not every time and the key issue comes up before even turning the car on.
