You will have to search the internet to find out about it, or experience the problem like I did. Can't find in Nissan recalls in their site either. I am talking about if you have the key fob within 1 inch of your Cell phone, and you receive a call, the key is usless and you are stranded unless you have a spare. The dealer did not tell me about it either. I read an article where some dealer says it only effects some cars?? Anyway when I went to the dealer to get mine replaced (after my wife had to bring me a spare), they told me that it would be 2 weeks to get a new one. I whined and they drove to another dealer in town I guess. Anyway my wife will not drive the car because she fears she may be stranded if she forgot and put the phone in her purse with her key. I cannot believe that Nissan could not have a backup plan. You cannot use the key in the key fob slot either the thing is usless. The car drives great though; just a really stupid design flaw.
