2006 Chevrolet HHR • 66,000 miles

This has been a on going problem, when we park the car overnite in the garage and the next morning we need to jump start it to get it going and its will start the rest of the day. This only happens when the car is parked in the garage. It has a brand new battery. I took it to a mechanic he could not find a
battery drain when he checked the electrical system. He said its probably the BCM on the car causing the problem. I spoke to a dealer he told me it was not the BCM, before I take it to a dealer and pay a lot, looking for suggestions. Thanks
