If completely different framed blades are missing the same spot, your actual wiper arm may be slightly bent. It sounds like pressure is not being equally applied. One solution is to go with a frameless design. I have PIAA Si Tech. Besides the quality blade itself that actually leaves a rain repellent after use, the frameless design ensures equal pressure along the entire length of the blade. Uneven pressure along the arm is the most common cause of missed spots...especially if swapping in new blades doesn't alter the coverage.
I put in the entire arm not just a wiper refill.
By frameless, do you mean the like the Rain-X Lattitude? It's strange that this should be an issue with a car that's only 1 year old without any snow or ice to deal with.
