Noticed condensation in driver's side headlight approximately 4 years ago. Has never dried out. Bulb in driver's side headlight went out and had to be replaced twice in the last year. It is now out again and headlight housing is holding water. The blinker still works but not the high and low beams. This is a safety issue when the bulbs go out. Picture uploaded of what it currently looks like.
Passenger side head light, build up of moisture in the sealed unit, results in loss of headlight beam, degraded over 50 - 75%. Unable to access headlight inside where moisture accumulates to wipe clean. Dealer claims only solution is another assembly (problem will probably repeat). Safecar shows a tech bulletin, Nissan claims it will dry, this is not the case and it degrades. This is a safety issue as the moisture and water degrades the vehicles headlight. Customer unable to access a sealed assembly.
