Re: 2009 4 Cyl Oil Leak
There is a bulletin regarding a leak in that area, but I don't have a link. The bulletin number is #08-06-01-017C which is a leak at the rear A/C bolt hole mounting bracket because of porosity in that area. It is an easy fix for the dealer since you are under warranty, but they would have to put oil leak dye in the oil and clean up the leak area. Then you drive it for a while and bring it back so they can narrow it down and fix it. It is fixed by removing the bolt when it is cooled down, clean out the hole, and then apply teflon pipe thread sealant to the bolt and then reinstalling.
The only other leak I have seen on these engines is the o-ring on the filter cap wears out and starts leaking, but that leaks in a different area than you described.
