We left yesterday on a planned 450 mile road trip from LI to my son's house near Pittsburg, PA. As this is the first EV we ever owned, I had range anxiety before we left. We charged to 100% and set off for the EA station in Bloomsburg, PA. We arrived with a 15% charge remaining and initiated charging. After a few minutes, I noticed we were only charging at 50kW. We have charged many times at other EA stations on LI and always start charging at 125kW. After about 20 minutes, a message came up on the charging screen that said " this function is unavailable". I could tell from the EA app and the Car-Net app that we were still charging so we just let it charge. After about an hour and 15 minutes, charging stopped at 80%, which I had set before we lost the screen. We set off for Bedford, PA. We had no speedometer and no mileage GOM on the small screen. The charging screen still said "this function is unavailable". The Car-Net app still showed state of charge and mileage remaining. I had a speedometer app on my phone that we used. Odometer on the status screen was also blank. We arrived at Bedford and initiated charging. It started charging at 127kW and ramped down from there. We charged to 80% and set off for my son's house. We still did not have speedo or GOM. We arrived safely, still with the same issues. I tried turning the car off, locking, then unlocking, getting in and securing seatbelt, restarting the car, but the same issues were there. It was getting late so I didn't want to start disconnecting the battery and doing a reset so we left it for the morning. This morning I went out, got in the car and all issues were gone. Everything seems to be normal. To say the least, this is the most interesting car I've ever owned.
