So I just got a new C300 and the wiper blade on the driver side shudders when it reaches the top and then as it comes back down. Been back to the dealership twice regarding this. All they do is clean the windshield and tell me not to put any wax on the screen or avoid car wash places that put wax on the screen. The first time they apparently replaced the wiper blades. I took the GLC we have to the same car wash place and the older CLA I had as well. Never had an issue with wax building up on the windshield in any of those other cars.
Anyone else have this issue with newer MB cars?

Reason: Adding video file of issue
This is a common problem; my 2018 suffers horribly from it. Its been back to the dealer multiple times; adjusting the wiper angle and polishing the glass did not resolve the problem. I recently had my windshield replaced due to a rock crack and the problem is 90% gone; I believe that someone else on this forum thought the windshield might be contributing to the problem. It's shocking that MB has known about this issue since day 1 and has done nothing to resolve it with the newer models.
I had the same problem when I bought my '16 CPO. Dealer futzed around with it a couple of times but never resolved the problem. I had to replace the windshield (with a non Mercedes one) due to a rock strike and the problem disappeared.
Try the Bosch wiper blades. They worked for me.I tried everything to mitigate the issue and nothing worked accept these new wiper blades. I thing the Mercedes wiper blades might be really sensitive. Thankfully I haven't had the issue with these wipers yet.
Complained directly to MB because it would do this in the rain too, and sent a note up to NHTSA as well. Mainly because it would skip during the down swipe in the rain.
This “executive referral manager” contacts me Friday and Monday morning tells me it’s a issue with grime building up on the windshield - BS. They gave me some special white cleaner from MB to use. Used it on Tuesday and today on the rain still having the same problem.
Checked the link, will they work for a 2019?

Went to parts geek and found these, might try this after I hear back from that woman at Mercedes once she gets the message that her well researched fix didn’t work.
Although my leased 2017 C300 coupe goes to MBFS in a couple of weeks, I figure I might as well chime in. Had dual wiper blade chatter from the first day I got the car. MB adjusted the blades' windshield angle on a supposedly super machine, changed the blades, scrubbed the windshield, and finally replaced the windshield...all to no avail for the full 3-yrs of my lease. Obviously a problem that MB doesn't take too seriously as they have yet to find a fix.
My 2016 CPO has no issue with wiper blades chattering. I think they replaced the blades as part of the CPO process. I assume they used Mercedes blades, quite possibly made by the same people that make Bosch, but maybe not. I have used Bosch on other Mercedes and on a 3 series BMW. They have worked flawlessly. Give them a try-it's not a pricey strategy.
I had the same chattering. What’s worked for me is using an alcohol swab and cleaning the rubber piece that contacts the windshield. I don’t know if this will work for everyone, but it worked for me. Prob needs to be done once every couple of months
This is a very wide ranging problem with the W205 (have the issue on my C400 as well). There is an inherent problem with the stock windshield and / or the wipers which MB have tried to fix by adjusting the wiper arms or using intensive glass cleaner - neither of these are generally effective. I've switched to Bosch Aerotwins based on a recommendation on here and it helped a bit, but the chattering still persists in light rain. Will try Aquapel next, but personally think a recall campaign is probably warranted as it's definitely a safety issue.
BTW here's a comparison of the wipers - Aerotwins on the left, stock on the right (the bodies are thinner and less rigid).
How come my blade looks different than the Bosch wipers thst is “supposed” to fit my c300. The top is mine and the bottom is Bosch. I can’t find the wiper that’ll fit mine
I hope my experience will help others with this extremely annoying matter...
After bringing my 2018 C300 to the dealership several times over a span of 4 months, they replaced the blades 4 times, and even installed a new set of arms, yet the vehicle still had horrible wiper chatter in light rain. This last time (today) they cleaned the windshield with a special MB cleaner and said the chatter was due to grime/wax buildup. This worked... for now.
They gave me a bottle of the cleaner and a microfiber, and said every so often clean the windshield with this, and this only. DO NOT take the car through an auto car washer, do not put RAIN-X on the windshield, as the wax from the car wash, and/or detergent from RAIN-X will cause a buildup on the windshield that when mixed with rain water will cause the wipers to chatter. This is what they gave me, as of now I do not have any wiper chatter at any wiper speeds.
After about 2 years of this problem, and even with the MB windshield cleaner, I still HAD the issue. I am happy to announce that I've found a long lasting solution.
