I too have had trouble contacting the 4x4 Garage in Canberra. I am waiting on door locks and also a door seal problem to be fixed for the front passenger door. I sent a few emails and left a phone message with the service manager. Eventually they got in touch last Monday.
Unfortunately, the fix for the door locks is still in limbo, with a redesign in the works apparently. I, and others, are apparently on a list to be contacted once the fix is released. No ETA at this stage.
The front deal seal is retaining water between the outer and inner seal. Apparently, according to the service manager, there has been talk of a redesign of the door seals, and this is the reason for the delay. However, none of the other doors have the same issue, so it looks like a trip into the dealer for them to figure whether the seal is just in the wrong place and covering the drain holes. Anyway, hopefully it is something simple and can be remedied quickly while we wait for the door locks.
