Service bulletin B640520

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.

During assembly, the cover of the fresh air intake was not fully seated when the screws were tightened. This cover can then leak condensation out through the existing gap.
