I guess the plastic trim around the seat bottom cushion gets more stress with normal use than the Acura engineer expected. A piece of broke off mine this weekend, after 9 months of ownership. It is at a mounting point just above the seat control switches. The broken part of trim has a curved tab which clearly is intended to support the trim on the square metal loop below. I think from repeatedly leaning to the left to reach the open door and close it after getting in, more pressure than anticipated transfers to the plastic, stressing this mounting point.
If I have the part replaced under warranty, I don't want to have it break again after similar use.
I am wondering if I am the first of our members to experience this problem, and if it is known to be a defectively weak part or a recognized design issue.
