Remote Start Issues Post-Update

[Astrotrain00]

For the first year, the remote start in Ford Pass worked awesome. Ever since the last OTA update however, my truck seems to enter the battery saver power down mode overnight at much warmer temperatures than before (one night of -15C now compared to multiple nights of -30C before) and, as a result, won’t connect with the remote start through the app. Anyone else experiencing a similar issue and found a work around? Would be nice to be able to actually use the remote start feature when it’s cold…

Mine just started this yesterday. I have a '25 Flash. It's been in the negatives here (near Flint, MI). 2,500 miles. It's a Job 1 Flash bought in Sept.

Two nights in a row. Pretty much since app update 6.5. I plug in, early evening, and then an hour or so it loses the connection because of battery saver mode. In the morning I have to take my daughter to daycare or go to work and this is just a nightmare in these temps. I'll look at the fob option, but I feel as though I shouldn't have to.

I am always plugged in when not driving. Today I put around 100 miles down and it was fine out and about. Remote started and no battery saver until I got home. I park and charge outside.

What are y'all's thoughts? Should I have a dealer check it out? Is it latest software? 12v going bad from maybe sitting on the lot? Just something we have to deal with in the cold?

I’ve got an appointment this week for them to check out and (hopefully) change the 12V battery. Reading some other threads that seems to be the common source of similar issues for others. Will update once I get it back if that was the case for mine too.

Oddly enough, my door keypad stopped working and passenger side window is acting up all within a week of the battery saver issue developing. Not sure if they are all related but definitely seem to have had lots of issues appear right after that update.

Weird. Let me know what they say. I made an appointment for Weds., but it's contingent on a loaner.

How did you end up programming this? I’ve tried probably 20 different options from other threads and no luck. The closest I get is it says “Key Program Failure” at the last step so at least it’s recognizing the fob exists

I had to try many times. I’m going by memory, it was a year ago, I recall deciding that the Ford instructions weren’t quite right and that the buttons on the FOB needed to be pointed in a specific direction when in the slot and that the amount of time in the slot needed to be shortened. I kept trying with slight variations in timing and it finally took. I programmed extra keys on my 23 Lariat 5.0 too and had the same issue - same variations worked in the gas truck too.

Battery passed the test so they didn’t end up replacing it. Not sure what to do now except continue to monitor. It hasn’t been as bad for the last week or so even with the weather being very cold. Going to try to get the remote start fob programmed again as that’s all I really care about from the app anyways

Thinking that is what's going to happen to mine, too. I'll probably go the fob route as well. Since it has warmed up a few degrees, it seems to be working as intended now.

I was wondering if some insulation around the 12v would make any difference in extreme temps? Something like this: https://a.co/d/0fsVLQI

Might wind up doing both just to be covered (pun intended).

Good suggestion! I can’t see the insulation making it any worse and, for the cost, definitely worth a shot. I’ll probably try the same

Following up on this for those interested.

Yesterday, after a few days of it working properly, I had the Battery Saver mode enable again.

In the intervening days, I purchased a 3rd party fob from Amazon with the remote start option.

I programmed it on Tuesday and used it on Friday a.m. It worked perfect. Truck started right up from the new fob. Took all of 30 seconds to program.

I haven't yet wrapped the 12v. Someone somewhere (here or Reddit or Facebook) also said they got theirs to 'wake up' by hitting the unlock and lock button on their OEM fob. That would then allow them to use the app.

Hope that is helpful.
