I am not sure what it is called, but I remember reading some people's posts about how the plastice peice under the car would fly off. I just checked my pARTS AND SERVICE INVOICE and it is called Under Body Panel. When I went to pick up my car he said that it was recalled. I never got any call or letter in the mail about the recall, so I just wanted to inform you all to ask your dealer about it when you go for your next check up! Good Luck and Drive Safe!
