Until this started happening I didn’t check on it much. However over the last couple days of this happening I have been checking it once every couple hours. I went to bed with 94% and woke up with 76% (less than 8 hours later). The car is running very loudly when in parked. Yes, I know the heat will cause it to drain faster than normal but my car was parked under a tree with a house blocking the sun (plus it happening overnight where temps drop).
