    Default Forester sucking dust

    I did a few hundred kays of very dusty roads and the inside of my Forester (2020 2.0) is covered in a layer of dust. Anyone else experienced it? I could see clear dust lines on 3 of the doors rubbers where it appears to have taken it in. Any idea on how to appreach the matter with the dealer?

    They can easily adjust the latches to make a tighter fit, just have a chat with them.

    Do you use the Forester's air conditioning function on recycle or fresh air?

    Thanks I have to say the buying and ownership experience was great so far and I am sure it will continue from the dealerís side. Just wanted to see if itís common and or at least fixable

    Recycle. Worst is on the side plastic of the rear foot wells where you could clearly see is a entry hot spot

    Driving on dirt roads with windows closed and vents on recirculation ? Iso intake from outside and fan on ?
    Old problem.

    This is the problem. You need to get fresh air into the car. On recycle the cabin tends to be at lower pressure than outside and sucks dust through every little crack. Especially the back doors.

    Put it on fresh air and at higher fan speed than normal. You pressurise the cabin slightly and the dust will be a lot less.

    Always use from fresh on dusty roads.. Never recycle. It applies to any vehicle. You have to maintain cabin pressure

    Nou gaan jy die naweek al die paaie weer moet ry om seker te maak die "vars lug teorie" werk inderdaad. Look on the bright side!

    Dealer said the same thing about the air system. Apparently there was a bulitin about it as well although he did say mine was particularly bad

    Thanks everyone

    I don't buy the fresh air etc story. My Forester is a 2006 and I have not had this issue even though I have done a lot of gravel with it. And I just leave the climate control on auto

    Well itís on record now anyway. The road that caused most of it is close enough to ride up and down to test. Previous trip we had no issues and did 100s of kms on very dusty roads

    Happens to many vehicles, not just the Forester.

    Recirc function actually causes a slight vacuum or low pressure inside the vehicle. This then sucks any available dust past the door seals.

    Weird, but a known issue.

    It isn't about "fresh air". It is about positive pressure inside the car. Auto setting is only likely to recirculate air for a few minutes after start-up. After that it will have the air inlet open and fan running - thus creating the positive pressure.

    sunroofs, especially in tip mode also create a vacuum effect and aggravate dust ingress.
