My parents recently bought a 2011 qx56, they traded in their 04. my father was complaining about water pooling by the joint of the wipers and not draining. I live 3k miles away from them so I haven't seen it personally. Is this common? i can't remember if the 04 had the same issue, but I have a vague recollection of it occurring in the 04. any input would be appreciated.
