I have a New Leaf 40kwh registered in September 2018. I've just received a recall notice from Nissan asking me to bring the car to a Nissan dealer to have a software update to rectify a potential safety issue with the Automatic Electronic Breaking System. That's all fine but in the same letter it also says they will be replacing the Lithium Ion battery earth plates. Surely the earth plates are not connected to the AEB system? Is there another issue with the battery which they are not disclosing? What's this all about?
