Service bulletin GCUS-3-863

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

17118-Service Update. Certain vehicles may have been built with a front bumper lower fascia molding that has only one tow hook opening when the molding should have two tow hook openings. This condition inhibits the ability to install a second front tow hook. Dealers will replace the front bumper fascia lower molding.
