Recently found out that my windshield has been leaking. Didn't notice it until after it was washed. Have been told by Kia Canada, that hand washing your car in considered to be "external forces " and may not be covered under warranty. I'm not a happy camper. I have only had this car 6-8 weeks. There was tree sap on it and that's why i had it washed. If hand washing your vehicle voids the warranty, i should have been told this. Very disappointed!!
