Each time at start up I get a message "Service needed soon" on the dash, 2017 CTS-V
No oder messages, no fault code. Oil shows 45%. What am I missing?

Is it just reminding you that your oil life expectancy is below 50%? I'm sure a dealer could scan that for nothing if you talk to a service advisor.

OBD scanner. Get the codes.

Does it say "Service needed soon" or does it say "Service Vehicle Soon", if it's the second it might be this GM To Reprogram Cadillac CTS Active Safety Control Module (gmauthority.com)

It says "Service Vehicle Soon". This sounds exactly like what is going on. Thank you
