Power Steering Light On problems of the 2006 BMW 330

I just had my 2006 BMW 330i repaired due to a steering wheel lock warning light which appeared on the odometer causing my car not to start. This occurred when I was ready to leave the parking lot at my job. The car would not start and the red steering wheel lock warning light was on the odometer. The shop replaced the battery and ibs sensor cable. I drove the car for one day without any warning signal and when I adjusted the steering column by releasing the lever, the yellow steering wheel lock warning light lit up on the odometer. The repairs cost me $1,391. 82. This car also was in the shop due to a recall on the airbag on the steering column. A local BMW dealership replaced this part two months before this problem with the steering wheel lock occurred. What other problems will I have with this BMW series? I believe BMW should refund my money for these repairs.
