I found this bolt under driver seat today. Looked in parts catalog and could not find any bolt similar to this for seat assembly. The closest bolts are 3 bolts on each side that will hold the seat adjustment panel to the seat itself. (4) but this bolt does not have a ring attached and has a non threading on the tip. Didn't look further cause I did not want to disassemble the trims to investigate - The bolt has letter "C" etched to it. It does not have any thread seals so I don't think it is an important bolt. I rather not to go to service center with all this Covid Surge. Should I be worried? Any guess what it may belong to?? P.S. I have been to SC 4 times in past for other issues. So they may have left a bolt from past inside the car.
