GLS 400D Rear Twitches on small bumps under Passenger's left rear

[Akif]

hi Guys. First time posting here. I have bought a GLS 400D which is 2021 model (20 plate) only done 27000 miles by one owner (ex-****nal football player). it is a good car overall but I have noticed since buying that at times over small bumps, the car would twitch to the left mostly. The bumps are usually the ones under the rear passenger side wheel. I have not noticed any slights come on when this happens (like the stability control etc). The tyres are brand new and wheels seem all perfect too. As I bought from Mercedes themselves, it is approved and still under original warranty but also confirmed by them that it is never accidented. I have had it checked once by the dealership though they say that the engineer drove it and didn't notice any twitch over bumps. i drive a lot with my family in there, usually 6 people and don't want to take any chances if there is something wrong with the suspension.

my question is :

1. Has anyone else who owns a GLS 2020 model onwards has noticed something similar by any chance?
2. Can someone offer some advice on what may be causing this and whether I can explain it differently to the dealership to have it rechecked?

Cheers

Akif

Hi Akif!

I have exactly the same problem as yours with GLS400d 2021. Car has 20000km on clock. I've sent it to two different dealers and they can't find anything wrong. Did you found something?

Thank you!
