Forrest Gump 9

I have this problem with my car for the last two years (may be even longer). Everytime I leave my car transmission in Comfort mode, next day the car would be death. As off the batteries would be total drain, but the car would start right up on a jump. Only in C mode. I can leave in S mode for a week and nothing would happens.

The first time I thought it was due to the cold in the winter months. But about three months ago that happened again. I just tested that theory again last week. Thank god I drive my car in S 99.9% of the time. The dealer/Indy have no ideas what going on. Just wondering if anyone else have the same problem.

That's really odd. I'd like to know the cause
