As a UK Nissan Leaf owner I’ll explain, they basically have given up on existing customers. They don’t really care about us anymore. The app works okay and does the bare minimum but it is clunky and slow. They have a new app for all models over 2019 or 2020 and it works better and is significantly easier for them to update and maintain.

The 3G service in the UK will go first as the 2G service provides a lot of emergency failover. The 2G network has around 10 years of service left and even then will probably be left on longer.

They want rid of as many old app users as possible so they can save money on server and development costs, the problem is that even modern 2018 Leaf version still uses the crappy app and have 3G cellular which will fall back to the 2G side when the 3G goes (before the 2G cellular is fazed out) so to blame it on 2G is disingenuous as they still have to support the app for the 3G models and still have to use those on the 2G network as the 3G will go first. I looked at upgrading the module to a 3G or 4G but there is no point because even if you do that they are pulling the app functionality for the car rather than the signal.

There is an ODB add on by open vehicles that will restore the service and is actually loads better but is a bit of a janky hack. https://www.openvehicles.com/ we may do this if we really miss the functionality and desire a £250 solution with a £2 monthly connection fee. We shall see.

So Nissan maybe not evil. But certainly not being honest and transparent.
