Dealer reported that moisture entered a waterproof enclosure that houses the brake modulator. Water entered thru a drain hole from the cowl and bypassed a plate meant to keep water out. Once effected by moisture the modulator shut down all functions of the car including the engine while moving. BMW blamed it on partial submersion of the modulator but car was never effected by water/submersion and the dealer agreed that their was no evidence of that and could not find anything to support that condition. Upon repair dealer went to great lengths to try and seal compartment and install diverter that was replaced in the repair to prevent reoccurrence. This is a very dangerous condition that appears to be a manufacturing defect in manufacture on a very limited number of cars made by BMW for this specific model. Owners need to know that the conditions experienced have a much different effect on safety due to the hybrid design than a standard non hybrid car.
