I’m afraid this condensation issue might be yet another ‘characteristic’ ! This time of skodas generally rather than just the Karoq. I suspect a lot of us suffer from it at this time of year.
My Karoq windscreen (and driver and passenger door windows) has started being very misted up in the mornings now. But not as bad as yours. If it’s actually running down the windscreen that’s a lot of damp and may indicate a separate issue. I carry a wet dog and a wet jacket and I can keep it clear (after the initial morning wipe down with an old towel) by running the ac which I have running all the time.
My Octavia used to do it too at this time of year and I seem to remember the octavia forum used to have a ‘my windscreen is full of condensation today’ thread. A bit like the first cuckoo of spring.
