Default Weird issue surging

2017 coupe automatic, 10200 miles.

This has happened 3 times now, and enough that it concerns me.

The selector is in the Sport setting.

The issue is as follows: I am driving along 25 - 40 mph and stab the throttle and immediately let off (like if someone cuts you off right after you start to accelerate) and within a second later, the engine surges and the car leaps forward, almost like lag. The surge is enough to cause concern about maybe hitting someone.

If I am driving and press the pedal to the floor , it shifts and accelerates just like you would expect.

Has anyone seen this?

I'm not an expert, but I would believe it has something to do with the programmed delay in the drive by wire throttle

I have seen similiar behavior with a quick stab on and off the accelerator at low speeds. My conclusion: it's normal and don't do that.

With 8 gears it takes a moment to dig down to the right one. Then you let off the throttle. This is def a driver error issue.
