While I agree with the first two responses that it's no big deal, it needs to be fixed by your dealer under warranty by replacing the vinyl strip and not stretching it this time when installing it and then re-caulking the ends. I would not be satisfied with just a dab of caulk to fill the holes.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
