Actually I know it is cut. It was not molded this way. The edge is too rough.
For those of you who checked the area near the drain plug, is it a hole in the underpan you used to get access to the drain plug, or was it a section that was recessed in the undertray.
In the owners manual there is a picture of the undertray when it shows where the drain plug is. In the picture, the undertray has two holes in it near the back. My undertray only has the left most hole. On the right I can see where the hole should have been but it is now missing about 1/3 of the circle so it is now a recess.
Also if I removed the drain plug oil would not get on the undertray at all since there is nothing there that the oil would hit.
Thanks for responses.
