2018 Nissan Rogue has persistent sluggish rocking at low speeds (1000 rpm, ~10 mph) that seems like a CVT issue but cannot be diagnosed or described effectively.

Existing diagnostic methods and forums don't help because the issue is hard to describe and no one else reports it, leaving the owner without a solution.
