Windshield Wiper anomaly
I just took delivery of a GLK 250 BTC, which so far I am very pleased with. I'm coming out of an ML 350 BTC, and I like it better so far.
I do however have one oddity that is a bit annoying. I noticed that during a moderate rain, the drivers side windshield wiper drags water about 1/3 of the way back across the windshield. I read some older threads on this (2010?) and was wondering if there was ever an official (or unoffical) fix for this. Seems that if the problem has been around for this long, they would have resolved it by now.
Anyhow, thanks for any input anyone can provide.

Thanks for the input !!
It's a combination of the windshield angle and speed. If you slow down, gravity will take over and the water will just run down. I only noticed it when going around 70mph, give or take 10 mph.

Your statement about it being hardly noticeable is not my experience. Next time it rains moderately I'll try to catch some pics or a video.

It doesn't prevent the little band of water being pulled back by the drivers side wiper though, but it may reduce it. I can't do a comparison because i Rain-x'd my windshield right from day 1.
Perhaps one of those little wings that clip on the wiper might help elimate that low pressure area behind the wiper.

in hard rain and snow. I would like to hear from other people having this problem so that we can get MB to do something about it.

The windshield angle makes it prone to pitting and rock chips (our GLK is just over a year old and already had one windshield replaced, this new windshield is 2 weeks old and already cracked and ready for replacement again).
This latest go-around had the dealer replace our wiper blades because they were quite damaged from the pitted windshield.
I'm going to go another year with this and if I can't get a process down to solve the issue, we'll be getting rid of our GLK as the issue occurs directly in the drivers sight line and it's quite a safety issue when it's really muddy outside.
