Just bought a 2019 Mazda 3 2.5L Skyactiv G and realized afterwards that it has cylinder deactivation. Should I be worried and is there anything I can do to help keep it reliable.

So far there have been 0 complains I know of about cylinder deactivation on that car.

Unlike so many other cylinder deactivation systems - this one seems very solid.

All known 4th gen Mazda3 issues so far have to do with either turbo engines or electronics.

1) If possible, turn VCM off. 
2) Drive it in sport mode, if it has it. This may prevent VCM from kicking in. Not a guarantee, but make it less likely. 
3) Keep up with your oil changes. Top off oil more frequently. If you plan on keeping the car, make sure it has the right oil, and enough oil, to help protect the deactivated cylinders. It’s not a panacea, and it doesn’t really solve the problem, but it may help a little. May.
