Does it rain in Germany?!?
Well sure enough today it rained and after 20 min they started to chatter again. AAAAAAAHHHH. How can it be they can design such an otherwise great car but can't figure out how to make wipers work properly.
I wish the wipers were as good as say a chevy cobalt!!

You may have thought of this but, just in case, is it possible there's a coating on the glass (perhaps for shipping purposes) that they forget or neglected to clean off? Sometimes vinegar will do the trick. Just a thought.
The window wipers are actually extremely advanced in these vehicles. They even change their angle of attack every few wipes!
Try claying the windshield (it sounds weird but I've done it on some of my cars that chattered and it works.) Lots of contaminants can collect on the windshield (shipping, VPC, dealer, etc..)

Also 303 windshield wipes work pretty well if it ever happens again (and it will over time.)
I almost lost my martini when I heard the "extremely advanced" comment

In my book, no matter how complicated you make something, if it doesn't work as well as the basic design it's a step backwards...

My rain-sensing wipers are a great little tech goodie that I can brag about, but considering they go off sometimes out of nowhere, and smear dirt all over my windows, I don't mind "keeping it simple" and doing the all so hard task of flipping the stock myself when some rain starts coming down.
If I do remember correctly though, in its defense, it does adjust its speed, etc. according to the rain-fall, which actually is very helpful and appreciated.
BTW, I've always applied your last line to the SBC braking system on my car. Sure in actuality it's extremely advanced, in essence superior to conventional systems, etc. But the mere risk of any failure and unreliability make it a big step backwards, especially on something as life-saving or potentially detrimental as a braking system.

But another GLK owner told me he clayed his windshield as previously mentioned and followed up with a Rain-X treatment. Problem solved w/o a trip to his dealer.
