It probably did nothing for the European owners of C-Zero's and Peugeot iOn's because I don't think they came with remotes like the stateside iMiEV's do. I did read somewhere that Mitsu was aware of the issue with the remote not functioning correctly with some brands of EVSE's, so I'd feel pretty confident that the next software upgrade will indeed resolve these problems - No promises of course, but since it probably wasn't considered a big enough 'issue' to recall all North American cars to the garage for, it probably will be addressed the next time they have the service computer hooked to the car for any reason
