The drivers side wiper leaves a streak at drives eye level during most rain events. My dealer has replaced the wiper 3 times but this has not fixed the issue. My dealer has verified this is happening and verified this happens on all Porsche Cayenne vehicles of this age and model. According to fmvss 104 and sae j1903 the area a (drivers viewing area) must be 99% cleaned. This streak is an arc about 2" tall and the full length of the wiper travel. Changing the speed of the wiper system does not eliminate the streak. This has not caused a crash yet but I feel it may in the future.
