Loose seat bolts..
On my 2011 Compass the driver's side seat started rocking about a week ago. Finally got to looking at it and one of the bolts that mounts the seat/chair to the rail sliders was loose. Naturally it took a star or torques bit? Anyway the size needed for my rig was a T-45. Had to buy a whole set today as I was away from home and didn't want to risk my safety in an accident. I will need ti get some blue thread lock ti prevent this from happening again. Just thought I'd share the info.
