Yes, everyone agrees that a full disassembly and cleaning would be the better plan. However, you can have it vacuumed and refilled ten times for what that costs and end up with the same results, a PTU that lasts forever. So just have the fluid replaced until it comes out clean and then start spacing your fluid changes accordingly. If you have money to blow then by all means go for the full toothbrush cleaning.

Fair enough. It looks like the 2015 had an option for a temperature sensor, I wonder if it is for the exact function you stated. Hope the one I'm looking at has it!

I hate to start an argument with a Moderator when I'm the new kid on the block but lets say that it is a tolerance issue and the fluid is gold until it overheats. Then that leads me to the question if why is it overheating under normal operating conditions? Ford is still at fault for a bad design right? They need to engineer it so that it withstands standard use. Whether that requires a different air foil design to cool the unit, different fluid to withstand the heat or completely different components; it was still their responsibility. If this were a rare case where a 22 year old was using his AWD edge in an 8 hour rally race and burned his PTU that argument would be valid, but not when its this common among the average users its hard to not start pointing a finger at Ford. I agree, only an idiot would do something that costs them a lot of money in repairs... such as admitting fault and having to repair hundreds of thousands of cars? Corporations have time and time again stepped on consumers to their benefit. Martin Shkreli, Wells Fargo, VW emissions are a few recent ones that come to mind. Ford may not have initially tried to push a product that was crap but sure havn't stepped up to address it!

Oh boy, the saga definitely continues.

JLK, at least it looks like the 2017 should have a drain plug to make your life easier. Follow the links above and check your engine type and you can like confirm via schematic but I would be surprised if they added it to 2015 models and then took it away.

Initially I would not have said it was a scam. But in my opinion when a company produces equipment for at least 7 years in a row with a design that is known to fail from the inability to service it, then they charge $1500+ to repair it when it would have lasted indefinitely with a couple of oil changes, I call it a scam. It would be one thing if they changed it in 2008 or 2009 or something but they didn't, they chose to continue producing a flawed design. And now it appears they have finally recognized the issue in 2015 based on the above schematics.

Thank you for your help samirmta, I'm still new to the being a home mechanic. I'm so use to calling them a power transfer unit after reading all of this wonderful information that I couldn't find it initially but I guess ford refers to them as a power take off. Looks like they completely redesigned it in the 2015 year based on your schematic and the PTO schematic I was able to find under the VIN I'm looking at. It appears they have added a drain plug. Also if you have the hot weather package you get a vent tube and temperature sensor..? I still don't see a service interval in the owners manual though, so I guess the breather tube will just be one more thing to unclog when the oil eventually turns to sludge on the unknowing owner.

I am looking at buying a 2015 Ford Edge Sport AWD and I just spent the night reading this thread and researching the PTU issues. This is an incredible thread and I would like to thank all of the people that took the time to contribute too it. I can't find much related to the PTU and 2015/2016 models but I did find a couple of posts that hinted the 2015+ model now has a PTU drain plug from the factory. Can anyone confirm this? Obviously no mechanical part can be expected to last forever but this PTU issue is an outright scam. If not for the ability to mitigate it with P.I.T.A fluid changes I would be walking away completely from the Edge. Are there any other glaring issues with the Edge besides the PTU problem?
