On the left front head lamp, I checked into this and found that alot of work would have to be done - looked like most of the bumper would need to be removed. I took the vehicle to the dealer and was quoted 1.5 hrs labor to change the lamp.
I called Nissan to voice a complaint about the design of the car that would require this much labor to change a headlamp bulb. They were not very sympathetic and even mentioned that "this was life" - "the design was good" - etc.
On the right front head lamp, the bulbs are easier to get to with no removal of plastics required.
I am thoroughly disgusted with Nissan concerning this.
