The Company I work for bought four new 2009 Lt cobalt and each has had the steering column replaced at about 7k to 10k miles. The powering steering stops working making turning into parking spots (repetitively very hard). The steering wheel itself just does weird stuff and then the car needs repair. Other little things stop working too. Like the light showing what gear in, does not work. The head rest is in a awkward position too. Many people that sit in the seat immediately notice the head rest hitting their head in an odd way.
The xm radio is nice. The Onstar service is nice too. The get up and go on the car is good.
