2018 E300 jitter/vibration after 65+
Thanks for the thought.
I dropped off the vehicle at service over the weekend, for them to inspect if it may be a mounting and balancing issue or a bent rim. I also asked them for a e300 loaner just to see if another one drive like this. Lo and behold, i notice the same vibration.... I had at least 7+ benzes in my lifetime, but i never felt this before.... does your e300 drive the same? I start to feel it in the gas pedal, and in the steering wheel and overall. Is it coming from the new 9speed transmission at higher gears?
I got this e300 exclusive a month ago. When I got my car there was noise form front of the car sounds like “thung~~~”, so I dropped twice since I got the car, but they said they have not have any solution from MB headquarters even they agreed there was the noise.
and today, while I drive my car on the highway 60 to 65 mph, the car started vibrate and shake, at the first time, I could feel through steering, and my wife who sit passanger seat felt too.
I called dealer and he said my car will be drop at service in next week. I hope they can fix it.

any idea what the service is called for the harmonics testing? I've done PICO so far...




so another thing that i'll just have to live with...




the promised to actually test drive it at 130km to try & figure out what the problem is..
the wheels are definitely properly balanced & i doubt very much it's the type of tires that cause it.
But could it be the driveshaft maybe? - A friend of mine told me it's quite a common problem with mercedes as they are rearwheel drive…?
On mine, I had been waiting for the weather to warm up before taking it into the dealer to try once more for a fix. Decided to try a new dealer here in MA, for fresh eyes on the problem, and also happened to find one that has a great stretch of smooth road nearby for an easy repro. I think the issue is slightly more prominent in warm temps, and after the car has done some prolonged highway driving, so when I drove w/ the foreman I actually drove it for 2 straight hrs before hand to make sure it was obvious. Anyway, new guy picked up on it right away. He put new words to the vibration, saying felt like when you put your hand on a washing machine that's on the spin cycle, and then that comes and goes cyclically.
As we were driving around he was hypothesizing about the 19" runflats, like others here have mentioned, saying they're often the problem, and vehicles are increasingly made lighter w/ less inherent vibration dampening mass... But he drove a '19 demo car, felt no vibration, then put that car's 18" wheels onto mine and felt the vibration. So he's escalated to MBUSA. I'm really glad to have someone who can quickly and consistently feel the vibration himself. Now just hope to find a root cause and not here "it's within spec".

This is absolutely great news from your end. On another post I mentioned I drove a 2019 with 19's RFs and it drove amazing and I believe they corrected the issue in the MY19s, So by comparing your car to a MY19 must be easier to tell the difference.
Having a foreman actual believe what your stating is half the battle and it seems like you got there, now if there will be plausible resolution is what we can hope for. Please keep us updated! Btw your E class is a MY17 correct?
I really wonder if all MY17s and 18s have this issue or if its just a few of us who are more sensitive or its the roads that we drive on!

Getting closer and closer to calling a lawyer. Anyone know about jurisdictional issues, if I want to bring action against MBUSA for selling me the car like this and not fixing under warranty?
