NHTSA Complaint #11494327 — 2017 LEXUS NX

I stepped out of my car in our condo complex after parking. and turned off the engine only after i stepped out completely. vehicle starts rolling. I opened the door so wide, in panicked jumped back with right leg pressing on the break/ turning engine , shift gear to park, as i have no control over the door. As i am trying to hold on the steering wheel and doing all the actions mentioned above , the door swung hard with my leg on it while the car is in rolling motion. It did stop , almost hitting the parked pickup car. damaged the door and the front fender. Dont recall exactly what happened, it possible that i may have turned it off while it is in drive (?) but vehicle is not moving. Lexus a luxury car made it too convenient with auto parking brake , doesn’t not have a safety feature to prevent roll off accident when vehicle is at full stop and engine turned off.(unlike prius). Repair estimated at $3,000-$5,000.
