Prius “hiccuping/jolt” when going slow.

Hi! Does anyone know what this issue might be caused by? I don’t know a lot about cars so I’ll try to explain the best I can. For lack of a better way of explaining, the Prius does this weird “hiccuping/jolt” thing when driving at slow speeds. It’s hard to describe but it’s almost like the jolt you see from defibrillator shock (sorry for the bad example). I’ve also noticed it’s having trouble accelerating. Thanks for your help!

 

I don’t know how to edit the post so I’ll post an edit here.

The jolt I’m describing lasts for like a second. It’s not ongoing or anything. Just a quick hiccup/jolt then drives normally.
