Deadmilenko,
I just had this happen to my wife's 99' LX470. It started while we were in Florida for Spring Break back in March. It was just a small crack so I thought I would take care of it when we got back to St. Louis. The day we arrived home, this part failed completely on the driver's side passenger door. Now there's a big hole in the door. A closer look at the passenger's side back door and it is about to fail also. Is there an after market plate available? This will be a hard part to "weld up" and the interior door metal looks like it is Aluminum but maybe not. This is a bit of a design flaw in my opioion and the local Lexus dealer is just scratching his head. HELP! what do I do?
