New Lexus Owners Club member seeking advice on water leaking into cabin of my 2007 RX400H. Love the car dearly but recent heavy rain in Sydney resulted in a large amount of water getting into the cabin causing the hybrid battery to fail. Is this a common problem with the SUV because it has happened before but not to the same extent and seems to be worse when the vehicle is parked in our drive on an incline front to back? Any advice appreciated.
