Brought X to dealer for Oil change, now has leak (not oil).

[NoCoX5]

Brought my X into the dealer on Tuesday for an oil change. It's been driven about 20 miles since. Noticed a wet spot under the vehicle a few days ago but wrote it off as just the wet roads because the fluid was clear and wasn't oily and no odor. Well that is until I walked out there this morning and there is a 2 and a half foot diameter puddle underneath the passenger side just inside and slightly behind the front wheel.

Any ideas what this could be? I haven't found the source of the problem yet.

Thanks.
