Noisy Windscreen Wipers

I am also having the same issue with a 2016 GLC 300 in the US. I've been to the dealer 6 times and have had multiple calls with MBUSA representatives. So far all they've done is replace the wipers and polished the windshield. All were temporary fixes.
They claim the jutter is due to a dirty windshield which I don't believe as I have 2 other cars parked in the same location with no issues. They also replaced the wipers while it was raining and I made it 10 feet out of their service bay before the issue came back. At that point the windshield was clean and the wipers are new.
I'll post any updates I get. So far I've been dealing with this for 3 months and I'm glad to know I'm not alone.
What I can't live with though is that the windscreen jet wash on the front doesn't work. I can spray that back window but when I push the button in on the stalk of the wipers it just moves the wipers and no water comes out. I assume that's how you're supposed to spray the front windscreen??

My GLC doesn't have this problem, however, the squawk is somewhat common both in the US and Australia.
Don't believe M-B has found a good fix.

Maybe it is part of the A service. I don't know.
But maybe MB knows there is an issue?

do you have prepaid maintenance through MB? If so, all the new plans include wiper blades.
have done the rubbing alcohol, replaced blades twice, etc
running out of thoughts...




How is it that the weather affects MB cars more than any others ? Clean the windshield with MB approved solution?! Total BS. I have driven 10 different cars in the last 2 years and Never experienced this problem. Never cleaned the windshield either. I don't think the rain falls differently. No excuses MB needs to fix it.
