Electrical System problem #1

The rubber sealing around the lift gate failed on the vehicle and water seeped inside the vehicle and entire bottom of the vehicle underneath the floor board thereby damaging the electronic components, engine wire harness and headliner thereby rendering the vehicle was beyond repair. This issue led to mold to grow on the roof liner inside and on the seats which caused breathing issues for me and my family. This put our safety at risk! after talking the vehicle to authorized Mercedes Benz dealer in san jose CA I was told that this is a known defect with the vehicle about which Mercedes Benz inc is well aware for years and has not fixed it or recalled vehicles having this safety issue. I had purchased this vehicle from Mercedes Benz of pleasanton on 6/10/2015 as certified pre owned (cpo) but I was not informed that this safety issue existed. I was informed by Mercedes Benz of san jose that the vehicle could not be repaired as mold would pose a health hazard for the occupants and the vehicle was deemed to be beyond repair and totaled. I had also purchased extended warranty at the time of purchase in 2015 but the dealership did not honor it for repairs.
