When was the last time the battery was used/charged?
I had a second battery to my drill and it deep discharged through lack of use and wouldn't recharge.
The Cambridge – Ontario, Canada site are manufacturing the 2022 NX. Not sure if that will just be the LHD version and the RHD (UK, Japan) versions still produced in the Kyushu and Tahara plants in Japan. Hopefully just a teething problem
Many models are, IIRC all RHD models are made in Japan, whilst many but not all LHD models are made in North America.
