I am a 2017 GLS550. I noticed this strange excessive body sway left to right while driving on slightly uneven road or going over small bumps. Anyone feels that too?

Bumping this, I have the same issue. Any takers?

2017 GLS550 and yep lots of sway over bumps in comfort mode, a lot less in sport mode.

Yeah, I wish there was a way to get our GLS450 to default to sport mode...

I have a 2018 S560 with about 40k miles and running on non runflats 20inch wheels. I replaced my runflats thinking it would resolve the rear end swaying when I hit a small bump or pothole. Did anyone have a solution to this issue ? In sport suspension mode the swaying is there but very slightly reduced.

It sounds like what you are experiencing is tram lining which is typical of wide sports tires. Deflating tires to normal load helps a little bit (see fuel flap tire pressure sticker).
