Probably not. A predictive "fuel gauge" for an EV is a tough nut to crack. Just ask the manufacturers who've been trying to solve the problem for years in forklifts and golf cars. There is no really good battery equivalent of a float in an ICEV's gas tank. Voltage? Nope, too unreliable and variable. Watt-hours? Better, but total available capacity depends on too many other factors, so all you know is that you've used x amp hours, not how many you really have left. When it comes to estimating remaining range, the problem gets even more difficult. Maybe Tesla does it better. I don't know, I've never driven one. But I can tell you that it's a non-trivial problem. It sounds like Nissan didn't solve it well, but I can't imagine what reason would they have to deliberately do it poorly. If they wanted to sabotage the car, there are many more effective ways to do so.
