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

53530 \- Service Update Bulletin. Certain vehicles may have a condition in which either left side, right side, or both tail lamps could develop cracks near a locator pin on the bottom surface of the tail lamp housing due to the type of lubricant that was used. Cracks could allow water to wick into the housing, appearing as moisture on the inside of the lens. Dealers will replace both tail lamps, using an approved lubricant, and water test.
