The visor on our 2011 nissan sentra 2.0 s blocks the view of our rear view mirror. we cannot use our mirror safely with the visor down. we have not taken to dealership to have checked. we have not had any crashes or injuries in our vehicle because of this, but it is very nerve wrecking trying to back out without being able to see. it has been this way since we purchased this vehicle and continues to be a problem even today. *tr
