Car was okay a week and a half ago when I stop driving it.

What is your question?

I started the car up a week and a half later and all my dash lights came on,( breaks, be careful breaking, airbag malfunction, alt, 4x4 etc ). BMW Rep said, its cold outside and I need to drive it to recharge the battery. I drove 30 minutes and it started feeling like I was loosing power steering power. Then my car speeds up and steer better if I don't stop at a light. I took it on the expressway and it drove okay, but those lights stayed on. What could it be? I never drive far and the battery isn't two years old. Everything in this car is factory only.
