The driver's side sun visor is not secure against the head liner when in the up position. On uneven pavement, the visor moves quite a bit. It appears as though it may drop down in front of the operator if a large enough bump in the pavement is encountered. The visor has been replaced twice and it is still necessary to insert a folded napkin/cloth between the visor and the headliner to keep it stationary. At this time the vehicle has 1375 miles on it. I first noticed the visor movement on the drive home from the dealership (after purchasing it (new)). I'm concerned the constant movement will eventually allow the visor to (unexpectedly) drop down from the up position obstructing the driver's view of the road in front of him/her. I am working with Nissan to get the problem corrected. The passenger side sun visor doesn't appear to have this problem.
