I have a 2011 defender XS, I've had since new so hasn't been abused. I have a problem with my drivers door, the inner framework is cracked and broken, Landrover have said its down to wear and tear...... Really it's only 4 years old. They won't replace the door but have offered to have the door welded but won't offer a warranty on the repair. I know the door is aluminium but I'm not a fat bird so would you expect this to have broken???
