I'm on my 3rd set of Wipers already and streaking is back again. Both wipers are creating streak lines in the exact same spots. Originally the dealer chalked it up to wear and tear after 45 days of ownership but then replaced on the house after he knew that wasn't going to fly with me especially given the identical streak marks on both sides. Once the new wipers are installed they seem to work fine for a month or so and then streaking comes back again on both sides. I'm pretty sure that the windshield is not warped or bowed so I can only conclude the wipers are failing somehow after a short period of time. Anybody else seeing lines??
