NTB03074J2021-05-10. Service bulletin. EXTERIOR LIGHTING. SERVICE INFORMATION Occasionally customers may notice water vapor or fog in the headlamps.

Nissan?s new vehicle limited warranty does not cover physically damaged (cracked or broken) headlamps. All current headlamp assemblies are vented to the atmosphere (not sealed). - This is necessary to allow for expansion and contraction of air from temperature "variations" (warmer or colder) without damage to the headlamp. - Moisture in the air sometimes "travels" into and out of the headlamp assembly through these vents. - Certain environmental conditions may cause moisture to condense. - The fogging/cloudiness should disappear over time when the headlamp is in a dry environment. See this bulletin for further detail.
