Service bulletin SF638
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
Field Service Campaign for Side Guard Assist. Certain vehicles, ordered with the optional Side Guard Assist (SGA) feature, were shipped with non-functional short range radar (SRR) sensors due to shortages from the sensor supplier. The non-functional SRR sensors will be replaced with the new functional sensors.
