Picked up my new GL350 yesterday and it is gorgeous......but driving home anytime above 60 i look over and the passenger seat is shaking. Not really bad but i can see it moving and i have stuff in the seat and its moving alittle..........i'm used to Lexus which are the bet riding vehicles made but was wondering if anyone else has this happen?

I've never owned a diesel and i realize they vibrate more but dont think a bucket seat should move at all.

 

I have a 15 350 gl too. Picked up last week. That's got nothing to do with being diesel. Does not happen in mine. Love the massage seats

 

I sent you a PM.
