Service bulletin A21040A

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

Service News - Rearview Mirror Mount Spring Replacement - The rearview mirror mount spring has a new design. Per regulation requirement, the mirror is designed to breakaway in the event of a crash. The mount spring must be replaced anytime the mirror is removed from the windshield. The mount spring for the rearview mirror is a one-time use item. Upon installation, a new mount spring must be torqued to the specification noted in Service Information.
