Owners of Nissan Leaf electric cars have accused the firm of "dumping its pioneers" after it announced its app would stop working for older vehicles.
It added: "Owners will, however, still be able to use key features such as Climate Control Timer and Charging Timer directly from their car's Navigation System."Affected drivers have told the BBC of their disappointment - in part because mobile network operators will not be phasing out 2G until the end of the decade."I would have expected at least six months, 12 months, something like that to arrange alternatives. This is a key feature of the car that's going away.
David Morris, who has a 2014 Nissan Leaf, received an email on Wednesday which said his app will stop working next month."Would I buy another one again, from this manufacturer, if they're not going to support it for a long term? Not sure," Mr Morris said.Though this issue affects a relatively small number of drivers, experts predict many more vehicle owners will encounter similar problems in the future.
He also pointed to broader trends within the industry, such as some car manufacturers starting to charge a monthly subscription fee for access to extra features such as apps.
