New Kia niro rolls back on inclines in drive after removing foot off of break and right before pushing the accelerator pedal in stop and go traffic, on paved, city streets. Never had this with other automatics. New Kia niro jumps forward/accelerates sharply while in drive while driving slowly (1-3 miles per hour) up an incline. This occurres on paved, city streets.

I accelerated to 65mph.I set the cruise control. 2 seconds later I see that I am accelerating. I press cancel at 72 mph. I press the cruise button again, turning off the cruise, then on again. Slow to 65, press the - set and it immediately starts speeding up. Second report. 4th and 5th time to happen. Dashcam recorded events.

When pressing the resume button the car has acceleration wide open throttle well beyond the set speed of the speed control. Most of the time the resume does nothing but set a new speed, the current speed.
