Why is this 2000 mile new car jerking and stuttering at steady low speeds?

What is your question?

While driving at steady low speeds of 20 to 35 mph and tach between 1400 to 1600 the car starts jerking and stuttering. Just a weird jumping motion. Moving down on the gas and bringing tach up above 1600 rpm will stop it from happening. Very noticeable and annoying. Took car into Chevrolet dealer. Duplicated the problem and then told me nothing wrong - "it's normal". Nonsense. This is a brand new 2019 1.5 turbo with 6 speed trans. 2200 miles.

What makes this problem better or worse?

Happens all the time.

How long has your 2019 Chevrolet Equinox had this problem?

Last week.
