Problem with battery drain on my 22 Silverado Highcountry. Plus problems with the adaptive cruise control.

Battery drain after sitting in the garage for 4 days.  Accessories would come, but wouldn't shut off. Adaptive cruise control says temporarily unavailable.  Checked windshield and cleaned it,still not working.

Mine does the same, it's been back to the dealer 2 times for a draw test, replaced the battery, no issues found, they feel it's normal. I gave up, when I drive my other car or go away I just put a Battery Maintainer on it.

Took my truck in yesterday. They the same thing, it was the battery. They replaced the battery and said everything else checked out fine...only time will tell.
