Steering Column problems of the 2003 BMW X5

I purchased the vehicle used, I have had it for about 5 months and have had some serious problems (steering column, window regulators, engine, and coolant leakage). I see where these issues seem to be consistent with the vehicle, but am having a hard time getting the recall work done. I can's afford to spend a lot on this car, but I feel like I may have more than I bargained for. My extended warranty is not paying for much !!! help.
