1) Water in doors
It seems that the doors are not draining rain water that gets inside. Nissan made a small adjustment to the door seal at the bottom of the door to try to fix this but it is still retaining water
2) Tapping/knocking at rear especially when braking or turning left
We mentioned this at the service and they adjusted the handbrake. This seemed to fix it for a couple of weeks but the noice is back.
The car is booked in for these issues on 25th April.
