2024 Lyriq – High Voltage Message

I experienced “Service High Voltage Message” on 2 trips today during moderate rain and fog. Subsequently, later today while driving to the Dealership for service on a dry road the message did not appear. Dealership seemed to have heard of this problem and mentioned a major software update. A different representative at the Dealership mentioned the word “sensor”. We are fortunate to have a very capable Dealership, however; I am sure they as well as the the Engineers at General Motors are still learning.

Last month, on the coldest day of the year, I got the Service High Voltage message and no heat in the car. When I took it to the dealer, they said it was probably the heat pump and they were on back order until the end of March. The dealer had the car for about a week when they called and said the car was fixed.
When I picked it up, the paperwork said it was low on refrigerant. When I asked why it was low, they said it wasn’t really low. Seems like typical service double talk. Should have pushed for a better answer.
Not at all confident that this is not going to happen again.
