The windshield wiper blades on my 2012 V are fairly new, about 1 year old. They make a terrible noise as they do their job, like the blade is not flexing as it moves across the windshield. The noise goes away, remarkably, at the highest wiper speed. The windshield was treated with Rain-X this past summer. I guess, despite their not being all that old and don't get that much sun exposure since the car is garaged most of the time, that the blades have gotten "old". But I thought I'd see what people recommend doing here? Assuming I have to replace the blades can someone recommend the best ones for the V? Thanks.
