Hi, Ive noticed there is quite a lot of moisture inside the glass of my sunroof and around the edges due to the ice and snow on the roof, has anyone noticed this on their car and is it something I should bring up with the dealer or is it normal? Its no dripping on to the seats but its def wet around the edges. Thanks

It's called condensation. If you park outside and the conditions are right, there is probably nothing you can do other than wipe it away.

Yes it most likely condensation. As you live in quebec you likely know how to get rid of it but I will throw this out anyways.

As you sit in the car and breathe, not good to stop doing that by the way, you exhale moisture. The car is warm and the air can hold more moisture (relative humidity). When you get where you are going and stop the car and leave the humidity is trapped in the air that is 50-60F in the car. As the car cools off from sitting there the air can hold less moisture and it will condensate on the outside windows, around the sunroof because that is where it is the coldest and freeze or stay wet if not cold enough to freeze.

Enough with the grade 4 science lesson, here is a trick that will help you get rid of it. First make sure you minimize it in the winter by always using fresh air in the cabin and not recirculation. Second when you have finished picking up those four sweaty teenage boys from practice and dropped them off, open one of your back window just a crack and leave it open when you park the car over night. This will allow the colder much dryer air from out side to enter the car and soak up some of the humidity and equalize out the humidity in the car to whats outside.
