These cars like to be driven a lot. Short trips like you are doing are not great for any vehicle.....however, you have to do what you do. There are so many power drains on the car as it sits (security, etc) that reduced battery charge is a common problem. Many of us have trickle chargers, but I don't use mine unless I am going to letting it sit for several weeks. Your battery may not have been fully charged when you got the X3. Get the shop to make sure you have a fully charged battery now, and try to drive it longer distances.

Sorry, not much help.
