How many people are noticing there air bag seam becoming more prominent due to the heat? When I picked up my car back in February, my airbag cover was smooth. Now after many months you can see and feel the airbag seam going down the middle and around the Porsche crest. This problem exist only on the sport wheel. The base carrera and multifunction wheel with the triangular center section does not have this problem. I am trying to get Porsche to replace the cover with the leather wrapped one, since the cars I have seen with leather wrapped air bag do not have this problem.
