Need Input:Road vibration/Shake
Dealer fixed and I've Been driving it around for about a week and the shake and wheel vibration from the blown mount is definitely gone BUT I feel like at around 80mph (my commuting speed in comfort mode) the ride is not as smooth as it was or should be. Seems like there is some vibration/shake still, it's definitely not the same as before but just wondering if any one else has the same feel at 80 and if it's all in my head because of the the motor mount shake and its normal road feedback.
Any input is appreciated, debating on taking it back have it looked over again but wanted to see what everyone else is experiencing.

Do you feel it in the steering wheel as a speed specific vibration might be a wheel balance problem.
Also, I wouldn't trust the dealer to tell you if the wheel is bent or not. It can be slightly bent on the inside of a wheel and impact the vibration. I had something similar with my ED1 wheel.
I think I'm going to take it to a tire shop, have them take a look at the wheels, check balance and what not.
Next time any of you are out and about, could you make a mental note if at 65-80 mph cruising if you notice any vibrations or if it seem just as smooth as 35-40mph.

I debated taking a new on on a test drive just to see if its the same

Normally a wheel balance problem will be smooth for a while and than vibrate and then smooth out again as you go faster. A good tire shop is the place to go.

I had a similar problem and 3 of my rear left wheel bolts were loose. like two three turns loose.
All the other ones were loose too but not as bad as my rear left wheel.

The Mechaninc explains the "dynamic motor mounts" and that they are just stiffening up at high speeds.
I explained that I know how the mounts work and that obviously the AMG is a performance not a comfort model and is made to ride more stuff than the other C class. They are going to double check the balance and everything but are "pretty sure" it's just the car characteristics.
So, if anyone could just take a few minutes next time you're out and cruise at 75-80mph on a nice smooooooth road (in comfort mode no music) and see if you feel any shake or vibration at that speed. The vibration I feel is pretty obvious and definitely not feed back from the road (it gets worse the smoother and new the pavement is).
I would greatly appreciate it. If they say it's good and you say you feel it too then I'll forget about it and go back to daily driving life.

It does not sound normal at all. (not like mine) If you are driving down a smooth road and continue to go faster does it start smooth and then start to vibrate and as you go faster the vibration goes away???
This would indicate a wheel balance problem.
Feel the tire and see if you find any intermittent cupping as you feel around the tire tread. Yours might not do that yet as it does take a while to cup but still might be a balance issue..

It's a smooth ride right up until about 65, then at 80 it's really obvious. Even my phone sitting in the cup holder makes noise from vibrating against the holder. At higher speeds I can really tell it I smooths out but it doesn't seem to.
It supposed to be done today so we will see. And I'll check the tires myself too if it's still there.
Thanks for the input, Asking a fellow AMG is a little easier than driving to anothe dealer and test driving a 2016 and going through the "lets talk numbers". I'll let you know how it plays out.
Thanks for the input!
Estimated to get it back in 6 days....
Makes me little weary knowing that the miss it the first time, especially when I told them that's what I thought it was and they said it wasn't.

I am unaware of this wheel / tire insurance? What does it cover, cost, and how long? Deductible? With how expensive these wheels are if it's offered when I get my delivery I may opt for it.

I'll let you know what they charged me.

Not sure what the price of new rubber and wheels are, it might be worth it might not. Mine was transferred from previous owner so I never did the math to see if it was worth it.

The fixed it and covered everything. But they always lead with "we will have to submit it to the warranty claims and if it does not qualify you will have to pay xxx amount"
I guess my next option is to take another AMG out to feel the difference.
It is a most likely a bent rim. I had the same issue, sent through everything and it was a rear rim. And I don't even recall hitting a pothole of any sort!!
with the ED1 rims it is easy to tell... Talk a look from far away, the red pinning will look off Eve so slightly. If it is an outside bend.
Get it repaired. New ED1 wheels are 2200CAD and I waited 2 months and never got one. If you are looking for a place and are OK with shipping Greens Wheel repair in Surrey BC, Canada is the best in the business.
Best of luck.
