I felt alignment out of spec and had the system checked. They replaced 3 bolts and said it's done but I still got the same problem. Figured out that E-Class "drifts" more than normal becuase of light steering. Common occurrence.

Front tires needed replacement after getting worn out from the inside edges due to bad alignment. It is a repeat "feature" - the car seems to eat either the front set of tires or the rear one. Driven 8 miles daily. No harsh turns or breaks whatsoever. But the issue keeps on coming up in 8-10K miles. And its either the front set or the rear. Car is always dealer maintained and all reports show alignment as correct and other components working as required. IF anything is off, i get it replaced immediately. This is my wife's daily driver and I don't like her or kids stranded on road side so I maintain it religiously.

I will record noise since it is still making noise at this time. Not repaired. Windshield reservoir appears to be leaking. Had to fill 3 times in less than 6000 miles.
