Service bulletin Bulletin 51H9

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

The paint drain hole on the front left of the underbody was not sealed due to a change in components. As a result, water may enter the vehicle interior at the front left through this paint drain hole. The underbody must be sealed on the affected vehicles and a check must be performed to determine whether water has entered the vehicle/underbody.

The document
