I got the recall letter today. It does mention throttle pedal cover in addition to the floor mats. I too don't want an inferior pedal cover replacement. From looking at the U.S based Ghibli forum, some say you can't tell the difference its just a little bit smaller, but one contributor said it was much cheaper looking!
I would like some definitive information, and I can't imagine how the mat fixing could fail looking in my car.
