enigma-2

If the dealer states that they can't change the fluid in the PTU and a new PTU must be installed, know that another dealer may be willing to change it. Also, most if not all transmission shops will change it. (Fluid has to be pumped out of the fill hole).

Ford requires the PTU and rear axle fluid to be changed after driving through a flooded street. These are vented assemblies and water will reduce the lubricating properties by q very large margin.

I believe that I would clean the FOB contacts first, just to eliminate the FOB. The fact that the car takes the programming and then doesn't retain the programming indicates that the RKE may be bad in the car. I don't know if would help or not, think I would try pulling the RKE fuses for a few minutes and see if it resets the unit.

The coils fail because the plugs were not changed. The gap grows too large, this requires more and more current to fire across the larger gap and this extra current heats up the coils over the safe operating temperature. When they get too hot, they fail. The PCM fails when a coil (or coils) fail. As the plugs were never changed, there are other areas to be concerned about. Change coolant, PTU lubricant (if AWD) and transmission fluid. Less important are brake, power steering and rear axle fluids. Wouldn't hurt to take a peek at the air filter, cabin air filter and seat blower filters (if you have seat cooling).

Its not a design flaw, nor should it be considered ad a recall item. It's a failure of thr owner to perform the routine maintenance of changing the plugs at 90,000 miles. When you replace the plugs and coils, you should be ok with the PCM. Usually it's the feedback from a defective coils that causes additional load on the output and the PCM fails. If it hasn't failed currently, it should be OK (no one can really tell without doing a lot of tests on the unit).

Common failure. I replaced the fan assembly on my 09, last year (still under extended warranty). You are going to need to replace the fan assembly (consists of both fans, support platform and fan controller). Whether you do it yourself (15 minutes, but you will need to get the car in the air), or have a garage do it, go with Motorcraft. Aftermarket have reported problems. Motorcraft runs about $220 w/o tow pkg, $260 with factory tow pkg.

Aftermarket panels are often made from a lighter gauge steel and not always made from galvanized steel. That being said, this aftermarket hood looks interesting: https://www.amazon.com/dp/B01MA3YLJ3/ref=cm_sw_r_cp_apa_Icr5zbH270ZHD

Any possibility the battery in the "new" FOB is dying? No way of knowing how long it sit at the sellers store front. Just a few bucks to rule this out.

X2 on everything Paul said. The only part I would add to, is servicing the transmission. Under "severe" service, the maintenance manual states change fluid at 30,000 miles if (1) pulling a trailer, camper or rooftop carrier, or (2) excessive idling or all local trips (think taxi). Basically, if your uncertain as the the service history, its best if you change ALL fluids.

May have been too much for the PCM.

Look at all the ratings shown on tirerack.Com. https://m.tirerack.com/tires/TireSearchResults.jsp?tireIndex=1&autoMake=Ford&autoYear=2016&autoModel=Edge+FWD&autoModClar=Sport&width=265%2F&ratio=40&diameter=21&sortCode=61028&skipOver=true&minSpeedRating=V&minLoadRating=S#0 Igor the winter tires and look closely at the OEM tires.

One word: Bondo. Seriously, here are the measurements taken off my 09 MKX. Length along drivers side, from top-of-cowl to chrome trim: 29-1/2". Width at cowl: 63-3/8" (straight line measurement, not along curve). Width at front (seam-to-seam, straight line, not along curve): 63". Length at center, top edge-to-chrome): 31".

FYI you can use a MirtorTap harness that plugs into the mirror's power connector to power a camera or radar detector. Takes only a few minutes to hook up, powers on when the car is started and disconnects on the power delay circuit (15 minutes or when a door is opened).

My 09 was leaving the radio on after I open the door. I sprayed silicone into the ignition cylinder and so far it hasn't reoccured. (But it's only a band aid I imagine).

My 09 MKX Maintenance Manual requires plug change at 90k. Sooner you change plugs better chance you avoid PCM (and future coil) failure. (Pay me now or pay me later...)

The short answer is yes. When the dealer connects to the IDS website, they use the car's VIN to retrieve it's specific "as-built" values. From this starting point, they can easily read any unauthorized changes. If they make changes (must be authorized to do so) they will also change the VIN database for your car, with the master at Ford/Lincoln. They are unable to make changes which were not allowed for your VIN. I was asking about my dealer turning on the backup camera on my car (the 2009 MKX did not come with a backup camera for the domestic models). Tech said he knew HOW to do it, but was not authorized to do so because my car did not allow this as an option for that year). One point to consider yiu must consider that making ANY changes can void your warranty in many unrelated areas of the card mechanical or electrical sysyems. For example, turning on the backup camera in my car could void my radio, amps, sync & navigation systems extended warranty. (Which at this point expires in a week). Installing a tune could void your cars complete engine and control systems and possibly more. (Tunes are specifically listed in the warrany statement as killing the car's warranty).

Single or dual controls?

Quick question. Do you know if your plugs have been changed? If you don't change the plugs around ~90k or so, the gap gets too wide, forcing the coils to draw too much current. Higher current cause heat and the coils fail. From only a guess, I would think the problem lies with a coil that's failing, not the PCM. When circuits fail, it's usually not intermittent (but that's not a hard, fast rule). Coils drawing extra current will fail intermittently, before then fail permanently. These types of failures are almost a lack of maintenance.

Some Ford extended warranties have "conditions" associated with them. On my current EW I have a $0 copay if I have it serviced at my local dealer. However if I take it to any other dealer, there's a $100 copay. That may have been what you were thinking of.

Try calling the SYNC support team (Monday-Saturday, 8:30am-8:00pm EST). United States: 1-800-521-4140. Canada: 1-800-387-9333.

Change dealers (even if you have to drive further, it's usually worth it). If you have an extended Warranty any dealer will honor it. It not, it doesn't matter. https://m.yelp.com/search?find_desc=Ford+Dealership&find_loc=Walnut+Creek%2C+CA .

2007 driver mirror assemblies are going for ~$120 on Ebay. As just the housing is cracked and everything else is ok, you could just add a couple of chrome covers and be done with it. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F251433133250

OEM LEDs work, LED bulbs have a lot of complaints, as not being a nearly as bright. Seen some new LED bulbs that feature several LED elements to get around the hot/cold reflector problem. Haven't read any unbiased customer descriptions about actual experiences yet. I don't believe alot of bs out there concerning LEDs. When it comes to this stuff, I'm from Missouri. Best light is HID conversions, but they do project more glare to oncoming drivers. Phillips are the most cost effective conversion.

Could have had your local dealer hook up their IDS computer and change the Power Point timeouts from 15 minutes to always on. Don't know what the electrical draw of a wireless charger is, certainly more than a wired charger, but you might take the other responder's answer and calculate the total draw overnight. Take into consideration cold weather when battery capacity is half that of summer. Think I read where a Galaxy 8 came with a 25 watt charger. That's a 2 Amp rated charger. Jus saying ...
