VEHICLE STARTED MAKING HUMMING SOUND WHILE ACCELERATING AT LOW SPEED. NOTICED A LEAK OF VERY DARK FLUID THE FOLLOWING DAY. TOOK IT TO MECHANIC WHO DIAGNOSED THE ISSUE AS A LEAKING PTU (POWER TRANSFER UNIT). I'VE LOOKED INTO THIS AND THERE APPEARS TO BE A ISSUE WITH THE DESIGN ON THE SEALS. IT APPEARS TO BE A PREVALENT ISSUE WITH FORD EDGE/LINCOLN MKX THAT HAS NOT BEEN ACKNOWLEDGED/CORRECTED BY FORD. I'VE ATTACHED A LINK SHOWING NUMEROUS COMPLAINTS AND SOME EXAMPLES OF PEOPLE LOSING POWER/ACCELERATION WHILE DRIVING. HTTP://GOTACLASSACTION.COM/15796-2/. *TR
PTU (POWER TRANSFER UNIT) WHICH IS A NONSERVISABLE UNIT FAILS AND HAS BEEN ON NUMEROUS VEHICLES. THIS FAILUR HAS THE POTENTIAL OF CAUSING A SERIOUS ACCIDENT DUE TO IT POSSIBLY LOCKING UP AND CAUSING A VEHICLE LOSE OF CONTROL. I DRIVE ON THE HIGHWAY AND DIDN'T NOTICE AN ISSUE UNTIL I SLOWED DOWN TO GET OFF WHEN I HEARD A GRINDING NOISE. TRANSMISSION SHOP TOLD ME I WAS LUCKY MINE DIDN'T LOCK UP.
TRANSMISSION SLIPPING,THEN SLAMMING INTO GEAR. LIKE EVERYONE THAT HAS THIS PROBLEM, AND THERE ARE MANY FORD EDGE AND LINCOLN MKX FORUMS ON VARIOUS WEB SITES HAVE BEEN COMPLAINING ABOUT THIS PROBLEM. TAKE IT TO THE DEALER AND THEY CANT FIND ANY PROBLEM. OR THEY SAY IT IS NORMAL, ARE THEY FOR REAL...IM TAKING THE TSB INFO TO THEM THIS WEEK AND SEE WHAT THEY SAY. DONT THEY EVEN READ THESE TSB REPORTS? HERE IS FIVE THAT I HAVE FOUND SO FAR. TSB 10-21-2 10-9-9 11-5-6 11-12-10 SB-21430 NEVER SEEN ANYTHING ON THE SERVICE WRITE UP ABOUT THESE TSB ISSUES AFTER I PICKED UP MY MKX. THEY RESET THE COMPUTER AND SEND YOU ON YOUR WAY AND IT WILL RUN FINE FOR A THOUSAND MILES AND START THE SLIP AND SLAM AGAIN. IT WILL NOT HAPPEN ALL THE TIME AND THAT IS THE PROBLEM WHEN YOU TAKE IT BACK TO THE DEALER FOR SERVICE. WORKING WITH FORD CUSTOMER RELATIONS CENTER ON THIS ISSUE. *TT
