Problem Description and Possible Solution
A fluid leak may be noted from the axle area. Red fluid is from the transmission. Brown fluid is from the power transfer unit (PTU). Leaks are commonly from the axle seal and/or PTU cover seal. Leaking seals should be replaced as necessary.

I'm leaking gear lube and have to replace the PTU at a cost of $2000.
MY 2008 LINCOLN MKX IS ALSO LEAKING RED FLUID. I PARKED IT IN THE GARAGE AND THE NEXT MORNING WHEN I WAS LEAVING TO GO TO WORK I NOTICED A PUDDLE OF RED FLUID IN THE GARAGE SO I CHECKED THE TRANSMISSION FLUID. IT WAS EMPTY SO I ADDED MERC-V TRANSMISSION FLUID AS RECHECKED. IT LOOKED OKAY THEN I LOOKED UNDERNEATH MY CAR AND THE FLUID I HAD JUST PUT IN WAS JUST POURING OUT OF THE VECHICLE AS FAST AS I HAD PUT IT IN. SO I DECIDED TO LOOK AT MY WARRANTY TO SEE IF IT WAS COVERED AND NOTICED IT WAS NOT COVERED DUE TO THE MILEAGE. AS MUCH AS THIS VECHICLE COST YOU SHOULD NOT HAVE THESE ISSUES WITH THIS MILEAGE.ONCE I GET IT FIXED, I WILL GET RID OF IT. I HAD A LEXUS AND DIDN'T HAVE ISSUES WITH IT UNTIL IT HAD 120,000 MILES ON IT.
FROM WHAT I HAVE BEEN READING I AM STUCK PAYING FOR THE REPAIRS AND FORD IS NOT GOING TO ISSUE A RECALL EVENTHOUGH SEVERAL INDIVIDUALS HAVE HAD THE SAME ISSUES. I WILL NEVER BUY A FORD AGAIN. THIS WAS MY 1ST AND WILL BE MY LAST.
My MKX has 84000 mi and I noticed black oil dripping on garage floor. Needs new PTU. Dealer said it was on backorder. He called around and found one. Must be a common problem if it's on backorder. I was thinking of trading next summer. One strike against Ford products. The Jeeps are looking better.
PTU is leaking. Out of warranty. Was told it would be $2000 to fix. Why isn't Lincoln addressing this issue on a $50,000 car!!
Power transfer unit leaking
Okay, I have an 2010 MKZ AWD but I'm sure it is very similar to the MKX. Long story short: PTU replaced at 39,000 mi (still under warranty) and now they told me I need the PTU replaced AGAIN and it is only at 82,000 mi but it is NO LONGER UNDER WARRANTY. What ever happened to Lincoln? They used to make great cars. I had a 1991 Town Car and it had almost 200,000 mi on it when I sold it. Now I wish I would have kept that car.
I have to replace the PTU, $1350.00
We are leaking oil from what the dealership claims is the differential. The seal has been replaced but there seems to be some gunk or burned oil stuck inside of the differential which is causing too much pressure. The dealership doesn't know if they can flush the differential without removing it and they want me to pay for a replacement. This vehicle is too expensive to have these problems at such low mileage.
Brown fluid leaking from ptu
I take my MKX in for regular 5000 mile oil changes and tire rotation which means I make appointments every 6 weeks. Most recent visit on 4-8-15 I was shown leaking and partially destroyed PTU on the dealer's lift. Cost to replace was approx $2000.00 . Dealer had spare which leads me to conclude there are many such repairs necessary.
I drive about 40,000 mles interstae each year and this company owned car is in top condition. Like the wheel bearing problem on my earlier MKX, I have to believe this is an engineering or assembly problem and needs Ford's immediate attention for this luxury car.
Otherwise this is a great vehicle; superior to any Jeep I had in the past.
Leaking fluid and whinning as I go down the road. I bought this hoping it would be a good one. Mmmmm not so sure now.
Transfer case aluminum cast housing completely broken into fragments / destroyed. Appears as though seal(s) failed in recent -20 f cold weather. Nearly impossible to get to, much less notice any fluids stains on snow / slush covered roads so I could have fixed before catastrophic failure. Absolutely horrible design, should be recalled warranty. Lincoln / Ford, when we are told there is over a month wait for replacement part as it is a common failure, I would of hoped you would have fixed this for your customers. Thanks for using your crappy seals that cost me a $4,000 repair bill, I hope you get stranded on the highway as well and enjoy the same feelings I did due to your poor design and customer care.
noise from r.f. wheel dealer confirmed RTU
We bought our 2013 MKX pre-certified with 20K from Gateway Motors and they did not disclose that the PTU had been repaired at 13k. We drove the car approximately 2k and the PTU and entire transmission needed to be replaced while we were stranded on our way down south. After 3 weeks it was returned to us and the Lincoln rep. was attentive and helpful, but we were very displeased that the dealer did not let us know about the pre-existing repair. I just noticed this week that we have fluid stains in our drive and after placing plastic down to see what the fluid is----it is transmission fluid leaking (red). So here we go again, with needed repairs for the leak and we have 25K on the MKX. Beware.
last service 5000 miles ago all was fine, this time it has PTU leak, brake booster needs replaced, power steering leak ....plus front brakes & rotors which have less than 20K miles on them. They are covering the brake booster because of so many issues with that but the rest comes to a whopping $2800 bill. I think the lincoln service is ripping me off
Mine went out and to replace this part is over $1500. This should be a recall. It is also a fire hazard.
Oil dripping from both sides of the car
During routine maintenance I was notified by the lube technician that my front differential was in need of service. Said Ford recommends every 60,000 miles. LOL
He showed me the fluid, really it was like grease, that he had obtained by removing the fill plug. That alarmed me enough to research the front differential and found it has no drain plug and Ford says the fluid is lifetime. My dealer says they can't flush the "gel" from the inside with multiple fluid changes.
