# Service bulletin SSM 50274

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

Some 2021 Bronco Sport vehicles may exhibit a hiss or rattle noise while driving. This may be due to an internal issue with the manual park release cable.
