I would say lack of ventilation, needs air flow.

There's not much the builder can do but there are things you can do...

Condensation happens when warm wet air meets a cold surface - the air cools and is unable to hold as much water as it could when warm.

And you say "especially when we bring the cars in wet."

The moisture on the car evaporates in the heat being given off from the engine and exhaust and the resulting wet air meets the cold windows and you get condensation - a perfectly natural physical reaction and to be expected in the winter months given the circumstances.

How do you stop it?

Let the car cool down before putting it away. Don't put the car away wet. Leave the garage door open for a while to let any warm air out. Provide some ventilation if you can - do the windows open? Buy, borrow or rent a dehumidifier and get rid of any lingering moisture in the garage.

This is not a matter for the builder - just the modification of your current routine. It will not be much of an issue in the warmer months.

Good luck...
