Gadgetjq Posted February 26, 2020 Report Share Posted February 26, 2020 (edited) The most commonly mentioned oil leak source for the 3.5L engine on Edge forums seems to be the oil pressure switch. The switch is located below and behind the alternator so you might want to look around that area to see if it could be the culprit. If it is, here's a link to a video showing how to get it out and replace it. Jump to about 10:30 into the video to get to actual location information.

Christine the Edge Posted March 6, 2020 Report Share Posted March 6, 2020 (edited) My 2013 Edge (awd) had oil leaking and terrible smell in cabin, too. This turned into visible fumes within a few days - coming from the hood (car was also lurching. I don’t understand why, but all happened simultaneously). The PTU - power transfer unit - had melted. I’m just joining this online group for the first time and looking for answers. The PTU melted 2 more times after it was fixed the first time. Finally, the shop also found the rear differential axle was broken. That caused the melting? I do not understand these mechanical parts, and now I’m trying to learn. The car was in 3 shops over a 103 day period (third time was because then waited on back order of the axle for a month and a half). It has been an utter nightmare to me. Worst. purchase. ever. What I don’t understand is how the shops messed up so badly . Is there not a standard procedure for failed PTU, and if the repair work does instantly fail (within 4 hours after the first fix; within 20 minutes after the 2nd), isn’t there some sort of legal obligation from Ford to guarantee their work? I called up through corporate as high as I could get (will keep trying), and basically Ford does not stand by their product. They offered $250 towards my car rentals, which totaled more than $3,800 over a 4-month period. The woman who had been helping me and seemed to have empathy suddenly was in a different department after the holidays, and all my correspondence seemed to disappear. The guy who took over for her emphasized that the $250 was a “goodwill gesture” and was a huge huge a-hole (I’m not giving his name out, but I have everything documented). *The warranty covered, yes, but I paid for that warranty, so I paid to fix all of that (btw the mechanical failure occurred in the 3rd week that i owned the car). Sorry, I need to put all this in a forum specifically for the PTU. But I hope to warn you... make sure they get it right, or at least in less than 100 days. If that bad smell and oil leak are similar to mine, it sounds like the PTU. (The smell was so terrible on the 2nd time melting that everything in my car smelled so bad that it had to be aired out on a balcony where I was supposed to be having a lovely weekend trip. And i had to throw away food!) Good luck to you!! Edited March 6, 2020 by Christine the Edge 1 Quote Link to comment Share on other sites More sharing options...

That caused the melting? Yes, a failed rear axle differential will cause the PTU to fail. The PTU drives the rear differential. Any binding or resistance will put tremendous load on the PTU. However this is the first I've read of anyone reporting their differential failing. The PTU in the 1st gen MKX's and Edges certainly have a history of failures. Mine failed at 193k if I remember correctly), and was replaced under warranty. But I've never had any problems with the rear differential. Wonder what caused it to fail. My sympathy on the very bad luck you had on yours. The good news is, after you get by this you'll have a great car. Quote Link to comment Share on other sites More sharing options...
