I've been charging my MS at home using the UMC for about a year now without any issues and the SvC checked the cable during the annual inspection, but a few days ago charging was interrupted and the car warned that there was a charge cable failure. I had to unplug the UMC from the wall and replug it as well as replug it into the car. All seems to be fine now, but I was wondering if this is anything to be concernd about or maybe the unseasonably hot weather may have had a role in this issue.
