OEM blades are starting to show lines. I've had them for a year, and within that year they worked flawlessly for the handful of times I actually used them. Wondering if u all went with the OEM inserts or went with another system altogether. Where I live it never rains, but pours when it does. My wipers spend most of their time cooking in the sun.
Starting with my 2015, which I had until earlier this year, I replace just the inserts. I had the original wipers the whole while and saw no reason to replace them. I'm going to do the same for my 2023, whose original inserts are still doing fine. Have you tried cleaning the inserts to see if the lines will go away? I live in the Pacific NW where it does rain a lot.
