Next steps for P1E00 and U2619 - U2624

Gen 2, 2018 still under BECM warranty. Traveling at highway speed MIL illuminated. MIL cleared on restart, read codes OBDlink. Listing shows P1E00 confirmed along with U2619 through U2624 and P1E00 as pending. Currently planning a highway test in the direction of my Chevy dealership. Will the service BECM under warranty if codes are not persistent? I could not find anything in forums related to U2619 through U2624 - possibly something other than BECM?
