I have a strange oily residue on my rear window and lift gate of my 2009 Ford Escape, but I should mention something first...
I brought my car in for a recall related to the transmission. They said they took care of it, but, they said I was also down 3 quarts of transmission fluid. I just bought the car 2 months earlier. So I don't know why it was that low in the first place. They filled it up.
In any case, after I brought the car in, I drove on the highway for a couple of hours at about 65/70 mpg. I noticed an oily residue all over the back of the SUV. I thought it was just weird and someone splashed something on it. I washed it off the best I could but noticed it was very oily. I brushed it off and didn't think of it much, until again I took another highway drive for a couple of hours and again oily residue. I washed it off at a rest stop and kept a close eye on it while driving some more, and it started building up again. So something is going on. I brought it back to the dealership and explained all of this. They said they put it on the lift and looked at everything and didn't see anything wrong. Obviously something is wrong, so I need to "prove" it and I plan on driving it early tomorrow morning to build up the residue again and then bring it to them.
Sorry for the longwinded posting, but any idea what this could be? It seems extremely likely it has to do with something they did. When doing some searching online I found a couple postings that sounds pretty related and they said it was a crack in their transfer case. Any ideas??? It's driving me crazy and i want to know real bad what is causing this, so any ideas at all would be greatly appreciated.
Thanks!!
