2006 Lr3 water in passenger floor

[mariderrick]

Sunroof leak onto passenger side of truck...alarms system going off randomly..
key fob not locking/unlocking,,battery dead.
I towed to dealership they advise to file water damage claim with insurance company now dealer and insurance company think my truck is a toal loss.
I don't believe this since this is the first sunroof leak and only on the passenger side....Please help me someone
