Seat Issues?

Hey Everyone,
My truck has 500 miles on it, and every bump no matter how small or how big, it sounds like something is hitting my floor board(clunking noise bouncing up and down) unless pushed all the way to the back. As for my driver side, my left rail does not lock in, in all positions. So on acceleration or braking, I can feel slight movement from the left side. Any ideas, suggestions, issue has been brought up before? Thank you in advance.

 

Just take it to the dealer, bumper to bumper warranty 3/36

 

Very true. Hopefully it’s something simple.

 

Mine does that too. The left side never fully locks. So it'll push forward or back during braking and acceleration
