Just got my a 2015 SL and wanted to take in to the local dealer to get the TCU upgraded from 2G to 3G. The dealer rep told me to about the modem recall and told me to bring it. Got to the dealer and in about 20 mins was told that it was done. I was really surprised that it was done so quick. The rep told me that it was just a programming that was needed. I asked the rep, so does that mean that I have the 3G modem and the rep told me again that all I needed was the programming. I get into the car and try to connect and no go. I call Nissan EV customer support they checked things and tell me the dealer is wrong and they have not upgraded it to 3G. They just disabled the already disabled 2G modem which was part of a recall. I go back in and the Nissan agent explained it to the dealer. Dealer acknowledged the mistake and is ordering the 3G TCU. Took about an hour and half to get this resolved. Now have to wait for the dealer to call me back, sigh, smh.
