The long story: took my Murano (Mo) into the Smith Nissan service center because my newer battery was going dead by setting overnight. They ran diagnostics on it in the morning, I called up there in the afternoon, because they never called, to see what they they found. They then explained that the A/C compressor was draining the battery and needed to be replaced and it would be 1000 dollars. It did not make since to me on how this could be the case so I drove up there to see if they could explain the situation. At the service center I was told the same story, I then asked how it that possible seeing that the compresor is belt driven and does not run from the battery? He then said well it's the A/C clutch that is pulling the power. Ok, but it should not have access to power when the engine is off. He said, no it has power all the time (after running to talk to the "technician", I use that term loosely. I just took the car home because it had shady written all over it, for someone that has any common sense when it comes to electrical systems, I ended up getting a 2nd opinion from a local car guy and he found it was a simple relay (or electronic switch) that turns the part on as needed. It was simply stuck in the on postion, which explains why the battery was running dead. Long story short: Nissan was trying to charge me 1000 dollars just to replace a simple 30 dollar part, that or they are that incompetent they don't have a clue what they are doing at our expense, grasping at straws if you will. Whatever the case, stay away from this stealership Smith Nissan. If you must go to a dealership try Fayetteville or Tulsa.
