Steering Rack And Pinion problems of the 2005 Chevrolet Classic

For a couple months, I have been noticing a noise when I turn left with my 2005 chevy malibu Classic. I went to my repairshop and they said my steering fluid was low, but they couldn't find a problem. Today, I visited the same shop and they found that my steering rack and pinion needs to be replaced immediately because I am running the risk of it locking up while driving and being unable to turn. I have done some searching online, and apparently this is a very common occurrence with my vehicle. Losing all control of steering is a very serious hazard and I believe general motors should be held accountable for this defect. Thank you for the work you do.
