PT-25.8.5 : Charge Port Functionality & Cold Weather Performance

[Maquis]

I would agree. I am having to launch the app to manually unlock much more than I had to in the past.

That is unrelated to walkaway lock.

I have read the release notes as well; however, the reality is - WAL worked before update. WAL barely works post update.

Updates have affected all kinds of things not mentioned in the release notes.

This update failed to install for 4 days. It finally completed yesterday (13 Feb 26), but my scheduled charging times and target location data in the app are no longer there. The Welcome Lightning also stopped initially. I'm not sure what other issues,, if any, have resulted. Anyone else's update have something similar?

I have scheduled an appointment with the dealer as those first four failed attempts were attributed to the 12-volt battery power not being at a high enough power threshold (80%). I'm not really sure what they should check for now since the update finally completed.

I had a similar experience. Update failed several times over a few days, each time giving the 12V battery low message.

After the first time the auto update failed, I put it on the battery tender and charged up the 12V battery and then tried manually clicking update now on the center screen. Failed. Tried again. Same result. Left it on the charger overnight so it would be fully charged for the auto update at 2:00 AM. Next morning, same thing. Failed. Low 12V battery message even though it was fully charged.

After a couple days of this, a message popped up on my app saying it was trying to do the update and it gave some tips to try to help it succeed. Things like truck must be off, etc. One thing caught my eye. It said all doors must be closed, including trunk, hood, etc. I realized that when I had been putting the charger on the 12V battery, I had been leaving the frunk (hood) open with the charger leads going in to the 12V. That night, I again put the charger on it but this time I closed the frunk on the leads, and that time it worked. So, the frunk must be closed if you're going to leave it on a charger.

It did erase my charger settings, but it did not erase my radio station presets, as others have reported it doing.

I can not get this update to take for the life of me. Must have tried a few dozen times by now. Never had an issue with updates until now. I tried putting it on a 20 amp 12v charger and a tender (separately). No dice. 12v is showing 14.4 volts and car scanner is showing 100% SOC. I had a couple soft dtc codes (air damn no communication and I didn’t calibrate the PCM for the larger tires I put on). Remedied them but still won’t update. Just had a sync update for Sirius radio a few days ago and that went through no problem. Tried turning off the headlights and unplugging my comma.ai. All doors, frunk and tailgate closed. Nothing. I’d hate to have to send it to the dealer for something so minor.

When I initiate the update it does the 2 minute countdown then shows “preparing to update” for a couple seconds before the screen goes black. Truck turns on fine and no warning or reason for failing is shown on my phone or truck.

I’m open to any suggestions.

I’m open to any suggestions.

Been there. Hook up a tender that puts out 13.5+ volts, not a smart charger, early in the day. Tender should be downstream of BMS. Then in the afternoon, turn truck on, but turn HVAC, radio, headlights off, and run truck for 6 hours. Have to also disable shutdown timer. After 6 hours, turn off truck and close all doors. See above about frunk being closed also (tender leads wont get crushed). Let the auto update attempt at 1am.

Also unplug all 12V addons like dash cams, comma, obd dongles. Keep PAAK and key fobs far away (can turn off BT on phone also). Don’t try to monitor anything, leave the truck alone on the tender.

This is the max effort, clearly not everyone needs to do this. If it fails, start earlier the next day or get the battery checked and replaced if needed.

I’ll give it a go. Thanks!

The problem with WAL is that it’s some sort of proximity situation. It needs to be time based like GM has had for years. Last door is closed and truck locks in 10 sec. Period. Makes no difference how close or far you are with the fob or phone. The way it is now. Sometimes I can be right outside truck and it locks. Other times I can walk a football field away and truck never locks. It’s always been very unreliable and never consistent.

I’ll do you one even better. How fucking hard is it to show whether the truck is locked or unlocked in the ap? Why are they updating dumb shit instead of fixing something this simple?

Goddamnit! Don’t get me started on the app interface.

Just like some other folks, mine will NOT update this PT-25.8.5. Always getting the Low Battery message. Been hooked up to the battery maintainer overnight. Battery showing full. Try to initiate the install manually. No go. Battery too low message. Getting real tired of this crap. All doors closed, frunk closed, no accessories plugged in, etc.

Just got the update, it erased saved charging locations and set the default charge to 100%, groan.

This is the second time that has happened to me with an update, $%*@!$^&@#

And one can't just add them back in easily, one has to have a charge session at the location first!

Why, Ford, why!?

So,...rather than leave my truck sitting at 100% for too long, I drove around to get it down to 90%, then I hooked up the PPOB to the house and ran it for...lost track, let's say 12 to 14 hours, to get it down below 80%.

I then set a one-time charge to 80% and plugged in the FCSP, and as soon as the charging began, I was able to use the app to add the location (home) back in and set the time (after 1am) and percent charge (80), and the charging stopped to wait for tonight at 1am.

What a pain in the butt...

If I had a dime for every time I had to screw around with some computer related update that fudged things up, I'd be a rich man...now I have that problem with my truck.

Is there a way to save the charge location data so it can be reloaded easily I wonder?

As for the update not installing due to battery issues a lot of folks as having...

After you replace your battery under warranty, set it up for regular battery maintainer hook up to top it off as often as possible - I have mine plugged in all the time when parked and not being used - the new battery should last longer if you do that - lots of threads about it.

Also, see this link from the Mach-e forum about the different ways to charge up the battery to get OTAs, maybe one will work for you:
