Took delivery recently of my new MX and all checked out good, except after driving it a bit now the driver's seat has become pretty loose. Upon each acceleration/deceleration (not hard even) it rocks a little forward/back, like slight tilt, feels like a quarter of inch maybe or so. On top of that, when it does it, it also makes a little "mouse like" squeak, over bumps, leaning to touch the touchscreen usually, slowing in traffic, etc. Lots. Anyone else have this issue? I have a service appointment on 9/26 to address it, but going on a roadtrip soon and was curious if there is a short-term temporary fix that is possible in the meantime until then... Thanks!
