2016 Subaru Legacy jerking from dead stop? Only in auto mode.

Have a 2016 Subaru Legacy at 79k miles, had CVT service done to spec with OEM fluid at 70k miles, and has been running super duper smooth. Today driving, only from 0-20, doesn't happen from 5-20, the car has a jerky acceleration in auto mode and revs bounce up and down between like 1.8k and 2.2k during. I am at a loss for what it could be and figured I'd ask all you. Second owner, still got a bit to pay on this car so I need it to last me a fair few years. Could budget $100 or $200 for repairs, but not until next week.
