“Harmonic vibration “
#51
I was strongly considering a C43 in 2018..In the end although I was getting a great price I decided on an Audi A4 Premium Plus with all the goodies. I'd read just to much BS with these C43 cars. I also was not a fan of the staggered tire setup and RFT ( no other choice) My Audi with sport package has a square 18" setup and a real spare tire. Shame after looking at these forums, I don't think I'd ever consider a Benz. Shame cause they do look nice, and in the demos I've taken the cars were nice.
Got off topic there for a sec, but I’ve owned BMW, Audi, Corvette, and now Mercedes and the Audi comes in dead last even when I had an R5R and not an A4. But it’s all about what you like personally man, but I wouldn’t base you’re opinion off these forums. Most of the things you read are problems every car runs into with the exception of these cars having more bells and whistles that can break on them. It’s bound to happen. Buy a Benz.. let your girlfriend/wife buy the Audi lol

Newbie
Bought new in Nov 2019. First noticed around the 1k mi mark, now at 4600 mi. doesn’t get better or worse with time and mileage. More of an annoyance.
Car is also in to address the MB command app issue, no data uplink from car to server. Render the mobile app and website services useless. Dealer says they in contact with MB USA to do a software refresh.

Yep my experience has been similar. They replaced my driveshaft once and after a few months the vibration came back, albeit intermittently. It's still very annoying when I notice it.
In addition, my driver side blind spot monitor light is on probably 80% of more drives. They've removed the bumper once and "switch around cables" no fix. Then they complete replaced the rear driver side sensor.. no fix. They've also replaced my HUD entirely as one day it decided to have a giant black circle appear.
Next month i'll be taking it back a third time for the blind spot monitor issue, but to be honest i'm almost to the point of dumping the car and going back to a trusted GTI. I never should have gotten rid of my MK7. 3 years and 0 problems on the car.

One more with this issue, harmonic vibrations when coasting. Late '16 model, bought it used in Feb. with 38k km. For me it's not very bad but it's noticeable, especially when the car is not warmed up. Once it's warmed it is barely noticeable, but I can still feel it. Also I haven't felt it so much since I've changed to the winter wheels which are 18" instead of the summer 19" - both sets are AMG C43 original rims with RFT. After I've read a few threads on the topic I won't even bother taking it to the dealer (it's still under warranty), it's not worth the trouble. Besides I don't think it's going to stay with me for too long, it's really not what I was expecting / hoping at all.
Same here mate, same here - from so many points of view. ![Frown](https://mbworld.org/forums/images/smilies/frown.gif)

i have same exact problem with my 2011 c300
when cold it shows up more and i get that rough shift from first to second in sport mode that goes away when warmed up (there is a thread about that in amg section)
but i also get this stumble at low rpm light acceleration.
at some point looks like the degen mechanic of previous owner filled the .9 tramsmision with red fluid instead of blue.
it was very bad when i picked it up almost not driveable
after draining fluid and replacing with blue it drives alot smoother.
but i still get the same rpm stumble and still get the bump during cold drive.
