Twice, a ‘service high voltage’ error light has come on and it has said it impacts the ADAS and safety systems and the acceleration of the vehicle. The light disappeared after a short drive, but the heating system stopped working. The first time, we took it to the dealership and they reset the system and the heat came back a little, but seems to struggle under 32 degrees, and especially sub 15/20 degrees. The second time was this morning — the heat is barely working at all. Very frustrating for a vehicle under 2000 miles.
