Hi all, I have a 2018 LS500 with massage function. The air bladders maintain pressure however I hear an air hissing sound which seems to be air escaping on inflation. I have looked online and it seems that I will have to replace the full cushion as the bladders are integrated within the cushion itself. Air is escaping from both the backrest cushion and the bottom cushion. Did anyone have a similar experience ?
