I got all the warnings, yes. I got ~ 400 meters with turtle mode, before it died completely.
I am not sure that I see an issue here. With elevation issues freeway speeds heating etc I can and do see ranges as low as 65 miles on a full charge. So at 80% and having driven 60 miles I would ha e to say that that would be near normal.
This was basically a round trip and the driving behavior did not change significantly between the trip to and from the airport. Same roads, same speeds (55 MPh on I5), same temperature and NO heater on. The total freeway driving part of the trip is ~ 14 miles (i.e. 28 total). And I have not driven 60 miles on 80% charge, more like 54. And about half of it at freeway speeds.
The problem is really that the last miles are the ones that count. Even the difference between e.g. 60 predicted and 58 until empty means you need a tow truck. In my case it was 60 predicted and 38 actual miles and that is not acceptable. I understand that one should not take the DTE to seriously, but overestimating range by 50% is bad. Given all the implications, Nissan should change the algorithm to underestimate by a 10% margin.
Another bad feature of the range estimation is this: If you switch to ECO mode, the DTE goes up, even if you are on the freeway and there is no difference between ECO and D at all.
