Backed my car a bit down by driveway to line up to pull in to my side of our garage. Driveway is very slightly sloped away from our house. After backing up I put it in D (and D was indicated on the display) and pressed the go pedal. Nothing. Except the car rolled backwards. Pressed down for D a couple of more times and same response. Put it in P and then back to D and this time it worked normally.
