Carrier/rack problems of the 2012 BMW 528

So I bought a BMW, then a lot of condensation and water got into a headlight and it messed up the wires and my turn signal stopped working. Ordered a new one and the same thing started happening, I got another one and the light isn't working again. Ive had multiple mechanics, BMW, etc look at my car. Come to find out the way the car was built, vibration off the road often creates cracks or micro fissures, that make moisture get into a headlight and people have complained numerous times. I don't have enough money to continue buying new headlights if this a manufacture problem. Especially in this pandemic. People will rather not use their turn signals and mess their connectors up then replace it and I don't blame them. These need recalled. Moisture doesn't get out until you take off the headlight and you need to take off the bumper to remove the headlight.
