Nissan probably screwed up your car when they changed the starter.
Rereading your OP, I have noticed the same thing a couple times with my car. If I drive home from work (engine warm), turn off the engine, and then immediately restart it (eg if I don't like how far I've pulled into a space and need to move the car), there is a <1sec knock when it restarts.
My guess is the A/F ratio is 'off' with such a quick restart and the car/ECU quickly fixes the issue. I don't know if it's residual fuel, time needed for the injectors to reset and start working, etc.
I NEVER get a knock when I cold start the car or wait a few minutes before restarting.
