- 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.
