Service bulletin TSB23-540-001

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

This service bulletin is about certain vehicles equipped with 92 inch or longer roof mounted light bars that could experience fracture of the light bar mounting brackets, as well as provides instructions to replace the light bar bracket with improved bracket design.
