Unusual rattle after dealer service

Hey y'all.

I took my 24 ND to the dealer for an oil change/tire rotation and to fix the TCS recall earlier this week. Since then, I've noticed a rattle noise coming from the front passenger side. Usually, it happens going over bumpy surfaces.

I've called and set up an appointment for them to check it out, but I wanted to know if anyone else here has had a similar issue. Also, how firm should I be towards them if they charge me for the fix, if necessary?
