Nissan’s stance is that this is an environmental issue and that though i do wash my undercarriage regularly there is no proof that the owner before me did… Though i have maintenance records. Nissan states i am the only complaint that they have received yet i have found ten or so in different online forums. All front passenger where the ac condenser drains. ALL service shops that looked at this van that were NOT Nissan affiliated told me that this should be a manufacturer issue. That if it was just a maintenance/environment issue it would be more of the undercarriage and not limited to the same spot in all of the 2004 vans.
