Service bulletin SB-26-18-001

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

On some Model S and Model X vehicles, the compression gap of the HVAC drain funnel seal is wider than intended, which may cause water ingress. Inspect the sponge area of the HVAC drain funnel for water ingress. If water ingress is present, rework the HVAC drain funnel seal.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
