 Purchased this car used - have had two weeks and am having steering problems.  The car refuses to travel in a straight line - the nose of the car wanders back and forth requiring constant steering corrections.  Just did research on the web and discovered that this is a COMMON PROBLEM with Optima's from the 2011 - 2014 range.  Contacted the dealership and they can't get me a service appointment until a week from now.   I am so disappointed - this is my third Kia and I feel like I've bought myself a headacheUPDATE TO ORIGINAL REVIEW - Three weeks after purchase, we had an accident with this car (which had nothing to do with the steering problems) - I have raised my overall review of the car, as it performed well in the crash and kept my family from being seriously injured
