Service bulletin 20CSA-01
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
Customer Service Announcement for a policy change regarding Detroit Service Information Bulletins (SIBs) will now have a 60-day expiration, starting on the release day of the bulletin. The intent of a SIB is to notify the service network of a major change to one or more service procedures. Do not save SIBs nor reference them for repairs, as they are uncontrolled and never updated.
The document
The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
