The car jerks when activating cylinder deactivation, does anyone have an idea how to prevent or alleviate this?

I would like to know as well. I have a 2025 Mazda3, only 5k miles. The transmission at low speed jerks quite a lot.

I have noticed the slight jerk basically at speeds of 20 all the way to 70 MPH under the right conditions. Best way I have found to alleviate less 4-2-4… is use sport mode and manual mode to lock in the gear of choice for desired speed and RPM. Observe the deactivation screen and “learn” how to drive to avoid deactivation, that alleviates most of the toggling between deactivation cycles.

Are you 100% sure that is what is causing it? Are you watching it on the infotainment screen to confirm?
