The telescoping feature on my 2008g35S sedan passenger seat leg support section is no longer working, and is stuck in the "out" position. Any way know how to fix this or lock it into place so that it is closed?

 

it is a manual lever so try pushing in the thigh extension into the seat while wiggling around the lock/release lever to get it to lock else you might have to look underneath the seat to see if the locking mechanics are loose or broken
