Wipers are terrible.

I have a 2009 Chevy Traverse. The driver side windshield wiper leaves of three inch strip of half wiped window every time it wipes them. I have tried a couple of different brands and all came with the same results. Has anyone found ones that worked well for them?

Have you replaced the complete arm or just the blade? Arms can lose spring tension and not keep the wiper blade firmly on the glass.

It is one piece. No springs.

Perhaps I'm not being clear.

Blade Refill: The rubber strip which contacts and cleans the glass.

Blade: The rubber strip and its support or frame connecting the blade to the arm.

Arm: The rotating member connected to the wiper shafts at the cowl.

I'm 99-44/100% certain the arm has spring tension, and if it's below spec the blade can skip.

Like many newer vehicles, the arms may be different for each side.
