Some customers may notice water entry into the front combination lights (as shown below). This is due to poor sealing where rain or other water can enter inside the light. To eliminate this concern, the shape of the front combination light has been changed to improve sealing ability.

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.
