My truck is a 2015. Although you have to trim the piece a little, it worked like a charm.
Although not the same vehicle, see this link for where I had to trim / modify the bracket

From what I understand, in 2015, Chevy tried to fix the issue by welding tabs to the seat bracket where the seat cushion attaches to the front seat bracket bar. it didn't fix the issue. Therefore, the fix is listed for a 2014 only. Modifying the piece per the link above allowed me to use it on my 2015.
Obviously, I cannot guarantee that it will work on later years, I think its worth a try for only $6.
Its very simple to install just trim with a dremel, clip it on and zip tie it. Don't bother with all the other items in the TSB I posted in the earlier post.
BTW - I am not taking credit for this. Just passing on what I found out and tried after my dealer refused to do anything to fix it.
