I have a parasitic draw. I drive the car home, park it and turn off the car. I hear a high pitch humming sound coming from the engine bay (when car is parked and turned off).  The high pitch humming sound will be stop after a few hours.  I hooked a voltmeter and saw that something is pulling power 2.5amps. I started checking fuses: 1. Removing fuse 86 sounds stops power draw stops  2. Removing fuse 90 sounds stops power draw stops 3. Check interior fuses nothing would stop the power draw.   Any thoughts on what can be causing power draw?

I caught mine failing I got out of the car and notices the dash lights were still on. I waited long enough to let everything time out and shut down but the dash lights were still on. I started and shut it down and the dash lights went off. I think there is a software issue but I doubt Ford cares

I think that's a good idea and similar to the approach the I took.  

if you have a new ptu, like r and r, it may be a good idea to do it at 3k for break in period. 

Just bought a quart of Redline 75W85 GL-5 for the PTU and a quart of MT-LV 70W/75W GL-4 for the RDU. Planning on doing the first fluid changes on the 2024 ST somewhere between 10-15K. I know this is a bit early, but after all the horror stories, seems like a good idea. Peace of mind too. 

Are there any 2019 Ford Edge rear defogger wiring diagrams?

Replacing the IMPA did not help. Tell me, what if I connect this heating to the rear window or mirror heating?

Yep. Search:   site:fordedgeforum.com whatever you want to search here

i was having the same problem with my 2007 ford edge. i changed those sensors out in my transmission and not even 3 weeks later it wouldn't crank at all  It's like it threw it's timing chain 

"Sometimes..."?  I think most times.  The search functionality on these forums is just not very good.  Not just this forum, but almost all forums I visit.  I have never had much luck finding anything on any of the forums I am on.  But your advice about using Google is spot on.  It even sometimes brings you to the very thread in a forum you were trying to find!  Very frustrating.
