After having my Karma wrapped 85% in Xpel and my windows tinted I got to drive my car for the first time in three weeks. My wife and I drove in sport mode with a full charge for 45 mins on a flat interstate without any issues. After having lunch and on the return home I noticed that the ICE was laboring. I also noticed that my electric miles had gone from 47 to 25 and I had not used any electric. My car has been unplugged in the shop for 2 weeks but it was fully charged and gassed up when I dropped it off and when I picked it back up. I brought it home last night and charged it all night before leaving. Before now I have not had any issues. My diagnostic says that my high voltage battery has failed and bring it to the dealer. Is ok to drive it back 2 hours away? I hate tow trucks, but I do not want to burn myself or the car up. Did I do something wrong leaving it unplugged? Is it okay to plug it back in to my home?
