Thank you. I checked at the dealership and after rotating, etc I still notice it occasionally at a steady 25-26 mph speed.
I took my OB Sport back to the service tech regarding the vibration when keeping a constant 25 mph speed. It seems this might be “characteristic” of the 1.5 liter when it goes from 3 to 2 cylinders and they suggested I drive it in Sport mode. I tried this and it does work. Nice to have a solution that doesn’t cause a repair at least.
