Rear door not locking

You might have the broken pin problem someone reported they had on the drivers door when picking up their new car.

WB - that would have been me! Yes - pin had snapped in the locking mechanism in the door which needed replacing. Took a couple of hours to replace and been fine since.

On further investigation, I have noticed that the lock lever inside within the door handle looks faulty. In the unlocked position, the lever does not come out as far as the others. Looks faulty. Prob needs replaced.....

Should have bought a coupe

I had the same fault with both rear doors on a Discovery 3. First time was under warranty, turned out to be a losse cable connection. It took them some time to find the cause as it wasn't a known problem. Second time not under warranty was the locking motor in the door.
I not saying it's a know problem, but each time they ordered a new catch/motor ready for when the car was in the workshop.

I could of purchased a coupe but my busy life prevents me from waiting a week to get into the back seats

Been to dealer. Most helpful. Either problem with latch or cable. Both parts ordered anyway and will be here tomorrow. So when they take the door trim off tomorrow, they will have the parts ready if required. It does lock now, however, the latch does not sit proud when open like the other latches. Probably the cable.

Pretty happy with dealer response...

I have never checked if the other doors actually lock when I lock the car. Might check them now.
