Mercedes-Benz GL450 water intrusion in battery compartment and driver's side floorboard affecting radio and air conditioning on Mercedes-Benz GL450

Some Mercedes-Benz GL450 owners report experiencing water intrusion issues that can adversely affect the radio and air conditioning systems. These problems often stem from incorrectly installed air conditioner drain hoses, which can lead to water leaks into the passenger compartment. Owners have noted that water entering the driver and passenger side foot wells may cause corrosion and short circuits in electrical components, significantly increasing the risk of fire. Additionally, the water leaks can create potential air conditioning issues, which may result in short circuits and pose further fire hazards. In some instances, water intrusion has been reported in the spare tire wheel well, potentially causing the vehicle to stop moving. It is crucial for owners to have any suspected water intrusion diagnosed and repaired by a qualified technician to prevent further damage and ensure the proper functioning of their vehicle's systems.
