Service bulletin 09-011-18-3448

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some customers may complain of condensation/fog inside the front (headlamp/headlight) or rear (taillamp/taillight) combination lights. The recent new models have been fitted with a clear lens which can cause the symptom to be more noticeable, however, it does not affect the performance of the light. This condensation/fog is a natural phenomenon that occurs when there is a fairly large temperature difference between the inside and the outside of the light housing. It is normal for very small water drops to appear incertain locations on the light units where the air is stagnant (condensation), making the lens look whitish (fog). This happens mostly in the corners and narrow spaces, and will typically clear during warmer ambient temperatures, or when the lights have been on for some time.

Recalls for the same vehicles and component

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.

Other bulletins for the same vehicles and component
09014162022-06-06. Service bulletin. White Milky stains on inner surface of headlight lens
09-014-16-3132a2021-01-28. Service bulletin. Some vehicles equipped with LED or Discharge type headlights may exhibit white milky stains on the inner sur-face of the headlight lens. Some customers may complain of the poor appearance. This concern is caused by gas that emits from a gasket in the lamp unit. The gas adheres to the inner surface of the headlight lens and reacts with the anti-clouding coating and moisture in the air to create white milky stains. The gasket material has been improved to eliminate this concern.
