Service bulletin SSM 50743

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 2021-2022 Bronco Sport vehicles built on or before 22-Feb-2022 may exhibit a hiss or rattle noise while driving. This may be due to an internal issue with the manual park release cable. If the noise is eliminated when the cable is disconnected from the transmission, install a new manual park release cable assembly. Refer to the Workshop Manual (WSM), Section 307-05 > Automatic Transmission External Controls > Removal and Installation.
