Service bulletin SB72-40

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 Cascadia vehicles built from November 25, 2013, the drain holes at the bottom of the cab doors were enlarged to improve drainage during the e-coat process in the manufacturing plant. The larger holes allow more cold air to flow through the doors, most noticeably in extreme cold conditions.
