I have a 2013 IS 250 and just recently noticed that on the bottoms of both side of the backseats don't have enough leather cover and thus showing yellow foam (near the seat belt locations). Does anyone else noticed this?

 

Well I would think your is250 should be under warranty ! So I would go to the dealer and see. Or there could be a recall !

 

Notice the white line. It seems like not enough leather to cover the foam but I did the best to cover it up. The other side has the same issue as well. If someone sit in the backseat it would reveal the foam.

 

No, haven't noticed this on my 2008. Take it in to the dealer and ask them to fix it.
