Service bulletin 12-233-18R

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

This bulletin announces a design change to the front and rear door body flange weatherstrips in response to concerns regarding the doors being somewhat difficult to close fully. The new parts make closing the doors easier while maintaining a tight seal against air and water intrusion and reducing outside road noise levels in the cabin.
