Official summary
Some vehicles may exhibit a white powdery dust (1) adhering to the inner surface of the headlight lens causing a poor appearance. This is caused by the edge of the lens support part interfering with the inner lens of the headlight under a strong vibration during driving, scratching the inside of the inner lens. As a result, the resin powder adheres to the inside of the headlight lens. To eliminate this concern, the support rib location of the inner lens has been changed to prevent the interference.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
