Now I'm confused.. are you saying there is no thermostat on the 2019 that looks like the image I added, and only this part that you mentioned?This so called “engine coolant control valve” mentioned in the TSB is the “electrical thermostat” been implemented on the 2.5L along with newly added cylinder deactivation since 2018 CX-5. It’s served as the old mechanical thermostat functional wise for better control and efficiency. Unfortunately it also becomes a first-year problem just like the EPB on 2016 CX-5.
You should call MNAO directly and tell them this new engine coolant control valve should be covered like old mechanical thermostat under powertrain warranty, no ifs or buts.
