You can read the recall notification on the Keystone website.
The list of VIN's for affected trailers is there as well as the details concerning the recall.
Here's the model/VIN information on the recall:
2020 Cougar Models: 22RBS, 23MLS, 25RES, 26RBS, 26RKS, 27RES, 27SAB, 27SGS, 29BHS, 29FKD, 29RLD, 30RKD, 31MBS, 32RDB, 32RLI, 34TSB

If you have any questions, Keystone RV is closed and their "normal response" is always, "Contact your dealership for any information"... So, if your trailer is in the VIN range, contact your dealership for information. If your trailer is not in the VIN range and you're concerned about "behind the scenes correspondence", your dealership should be able to coordinate any answers you might need.
ADDED: The date of the recall is October 25, 2019. If your trailer was manufactured on December 4, 2019, I'd suspect that Keystone had already changed the assembly line to eliminate the issue on "trailers made after 10/25/19.
