l just bought a brand new 2007 Hyundai Santa Fe. We recently had a big downpour in my area. Every time l go to drive my vehicle now, there is a fog on all the inside windows that takes 5 - 10 min. to go away using the defroster. This has never happened to me in any of my other vehicles, and l wanna know what is causing this, and how to fix it! The vehicle is brand new, and l do not think this should be happening.

water is seeping in from somewhere l now because this happens with convertibles something is wrong with your car maybe a window seal

You could have them check the seal, but more than likely this is normal, especially if your car is kept outside or driven in the early morning. Try turning on the recirculating air feature on your air conditioner and see if that does not solve your problem.

It would be wise, to read the section on your Manuel open it and read what it says on defogging. If that wo not wo not work take it to the dealer and have them give you an explanation.
Good luck.
