As I think this should probably be the main thread on this (although several others seem to be popping up --- note to forum admin to consolidate maybe; didn't see a reference number on the email from Nissan though) thought I would post here as I just called my local dealer and as I have Friday and Monday off may bring in the car then if they have the part in question (if they do, the tech they have is a really great guy who should be able to show this thing to me and I can snap a quick photo); we have snow out here during the winter months (like --- now!) and I can remember a similar 'update' to a '98 VW New Beetle TDI that I had that required something similar --- think I recall that it affected the MAF which of course EV's don't have, but in any case it was a 'snow screen' that prevented snow from clogging the engine --- don't know why the LEAF would really require this perhaps they've had some cars getting packed up snow in the engine compartment --- highly unlikely in the warmer states of course. As to the other software updates, will be curious as to what they'll 'fix' --- we have however on only one incident where we parked the car, left it 'on', but it was in Park and I locked it. This can happening with such a quiet car (saw that someone testing a Lexus CT200h did the same thing on a road test). A better interface to Carwings is just a nice to have, a better GOM would be an improvement so we'll see. Hopefully Nissan has provided this part (although I see someone already posted that it may have to be ordered) before notifying the LEAF customers but we'll all see soon --- BTW, dealer is McGrath in Elgin, IL (outside of Chicago).
