2015 Acura TLX cruise control problems

When I am at a complete stop with my foot on the brake, it feels like someone is bumping me from behind to make the car go forward. Or another way of saying would be that the car is trying to accelerate when my foot is on the brake. Also, when accelerating, it feels at times like there is not enough gas and then the car starts speeding up. The transition is not smooth. I was told by the salesperson it was a shifting issue and the car needs to warm up.

Tl* the contact owns a 2015 acura tlx. The contact stated that the vehicle experienced abnormal jerking between gears, abnormal acceleration when starting, and abnormal shifting while driving 45 MPH. The vehicle was taken to a dealer where it was diagnosed that the transmission fluid needed to be replaced and the shift point software needed to be updated. The vehicle was repaired but after 500 miles, the failure recurred. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,500.
