Hello,
I just wanted to add to the body count mine started two days ago. I will be attempting the fix this weekend. Thank you guys for all the great advice. I’ll update with progress.

 

Hello Ford.

Do you have any idea when Corporate will release a fix? Following this thread and others that appear on this site it's hardly a one-off issue.

Thank you

 

I did the reset two times in a row completely shutting down the truck in between each one as I read to do on the Fmod forum or whatever it's called, then I was able to upgrade to the newest version of sync from the previous 22251 with Cyanlabs. So far so good but I'm not holding my breath

 

Was this bug introduced with 3.4.22251 and newer? Or is only 22251 affected but newer and older are OK?
I'm still on a slightly older release and want to make sure I do NOT move up to a version with this bug...

The crazy part about this is that dealers are charging people hundreds to thousands of dollars for an APIM swap to fix this, when it is fixable in software, and 100% caused by Ford.

 

I've read through this entire thread digesting as much as I can. What I've come to understand is that the bug was first introduced into the 22251 build but reports from others is that it still also exists in newer builds. Lastly, there is no software fix from Ford yet but rumor is that it's coming in October timeframe. This last statement corroborates that the bug would still be in builds newer than 22251 (I've only seen 1 newer build number so that may be the only other "infected" build number aside from 22251 that exists in the wild today).

I skipped 22251 and went to 32088 manually. 32088 does not seem to have this issue.

 

Well My son stopped over. I tried the downgrade USB and it resarted after about 30 secs. so nogo.
Gonna have to do the jailbreak method.
Well an edit!!!
last ditch effort. I tried remove gracenotes from cynlabs.. Did this and then tried downgrade USB. It loaded and went down to 3.3. Did a master reset and tried loading 3,4,23088 It would not start . Tried my old usb 3.4.22251 and it would not start.
Did a master reset again and when Updates screen popped up I hit yes. and then it started to update. I hit dont update after the downgrade. Well removed the 3.4.22251 stick and inserted 3.4.23088 usb and it started and showing reformat in process. Keep you all posted.



Edit--- UPdate completed to Sync 3.4.23088
I turned off auto updates for now. Unitl confirmed no otehr issues. Dont need this happening again on 4 vechicles.(well 2 fixed so far. 2 more to go) The reformat takes some time.
not sure if I got lucky or. what.
I used cynlabs
Created removed gracenotes USB ...did procedure
Then mater reset and turn on updates.
Inserted downgrade USB from cynlabs next. Reverted back to 3.3(this only took about 10-15 mins)
Master reset and the inserted full 3.4.23088 with reformat. (this took about 45 mins. Actaully trk turned off due to batt saver. So let it idle and it took off right from reformat process(was scared there for a sec) I was in the house and came out and everything was off. . Few mins earlier it was only about 50% done so knew it failed. but it continued once I started the trk.
let it idle untiul complete.
Also have maps 22 my street now displays.
Hopefully this will work for others. I did not jailbreak etc...
these 2 trks had all the same symtons....delays , no memory, back up camera problems, asking to tun on updates each time.
one more trk to fix, I will post back if goes good or bad.

 

If techno-geeks can fix this (read as a compliment)
Then why the hell can't ford corp do the same?
the procrastinating paranoid, "who is gonna sue me" tie wearing, sit behind the desk, that don't know ****e... why cant they fix this?
FoMoCo created the problem, they should fix it.
One more!
to reset the Sync each time you are in your truck/car. THIS IS DISTRACTED DRIVING What kind of law suit will ford have on their hands?

 

I just picked up a pre-owned 2020 XLT a week ago (Blue Advantage Gold CPO, so it has a 1 year bumper to bumper warranty). Realized after the menu and screen prompts showed up a few times, there might be something wrong. Glad I found this thread! Mine has the same host issues, and also forgets my phone each time.

 

good thing I didn't hold my breath, doing the same thing as before again.
