Ya as
@R Veloster N already stated that to me is a warranty job take a picture send it into your service manager and say it just fell off while driving they will either ask you to come in for it to be replaced or they will ship you one out or even better collect it and fit it yourself, if you do end up fitting it yourself you will need to use a 3M Primer adhesive promoter as without using the 3M adhesive promoter it will only fall off again. So take all the residue glue off as it is firm plastic same shape as the N make sure you clean it back to the plastic then apply the 3m primer adhesive maybe give it two coats wait 10 minutes for it to dry and once you apply the new N symbol the VHB tape that will be on the back of the N emblem once that VHB tape makes contact with the 3m primer it will be nigh on impossible to remove without using considerable force so either whoever applied it did not use the proper procedure.
