 About a year ago a very irritating whining noise in the car cabin was herd. Went to dealership and they said it was the power steering pump and it was "normal" I have owned the car 24 months and the first 12 months no noise existed. Another 12 months of driving and the whining appeared and is getting louder every day. This is not normal and makes my drive very unpleasant. I now hate my Altima and Nissan has had hundreds if not thousands of complaints about the power steering noise and refuses to do anything. I will never buy  another Nissan. Update.. I have owned the Altima almost 3 years now and still have the noise and still Nissan has done nothing even though it is still under warranty. Now I have brake noise after 30,000 miles and again they did nothing.
