I've got white string coming out from my rear seats between the seam of the back part of the seat and the part that you sit on. Not sure if this is a part of the seat or something that was left over that they didn't remove.

 

Simply a mistake. Do as my wife does with itchy labels on her clothes and cut it off as close to where it enters/exits the base material and be done with it.

 

That is from the clear plastic seat cover when the car is shipped. The string is around the edge of the seat covers. The dealer didn't remove it properly..

 

That's for the rear passenger. Instruct them to pull it when you determine they become a back seat driver. Instant ejection.

 

I have the same string in mine. But it only shows up once a month. Car drives heavy and bloated after. It handles a little erratic for a week or so. I usually just park it until it goes away.

 

Lmao these two answers are funny

This is correct, I had my car delivered with all the plastics still on and I removed them myself. That white string is a pain to remove and it took me some time, the person at the dealer removing it probably got frustrated and just tried to stuff the string back into the seats. You can just carefully pull it out.

 

I agree. haha!
