Hi everyone 

I have a 2016 Mercedes-Benz A200 with 57000 kilometres on the clock 

I recently encountered an issue where the car starts shaking at high speeds (between 120-140km/h or 75 - 80mp/h). 

I took it to the dealer and they mentioned my rim was buckled. I got that fixed and also balanced all the tyres and done a realignment. My tyres are also in really good condition. 

After doing all of that, my car still shakes at those speeds. I seem to feel it more when I go uphill as well on the motorway. 

I mentioned all of this to the dealer and they keep telling me that they don’t know what the problem is. 

Any help would be really appreciated! 

Thank you!
