Connectivity Dead - 2024 F-150 Lightning Lariat

[tearitupsports]

No apples allowed, so no carplay, but I do use Android Auto all the time and to your point, it was working wirelessly while the rest of the connectivity was dead, meaning that the WiFi hotspot that the sync system sets up was functional.

I do use Alexa in the truck on a regular basis, but none of this seemed to cause the crash.

I have had it crash more often when using Alexa than any other time. Sometimes it crashes mid song. Other times it is the exact moment it changes from one song to the next. I am actually going to try disabling Alexa during one of my tests and see the results. The kids will hate that, but it only works about half the time anyway.

Well golllly [/gomer]

If I'd actually gone out to look like I just did on my coffee run, snapped a photo!!!

I stand corrected.

Updated chart, so the 8/9 ... and so on are covering multiple systems on the one large fuse.

So after pulling fuse 32 and going on one trip of about 2 miles, the modem was locked up again when re-starting the truck. Interestingly enough during that time I received the karaoke 10.1.0 OTA.

I believe this is why I say that fuse 32 is not a reliable solution though. I believe there is something else going on that the fuse just doesn't take care of. I have gone ahead and pulled all 3 connectors off the modem for about a minute. The next time I will pull both fuse 8/9 and 32 at the same time and see what happens. If that doesn't fix it, then I will pull the whole battery terminal, as I should be up to date on software after the 10.1.1 update.

Here is a pic confirming the problem, even though I already knew what was going to happen. This is the charging location app. For reference this is at home parked in wifi zone. If the modem was working it would show the wifi icon with full signal and the up/down arrow icon.

Sadly - I really think a 10 mm wrench and pulling the negative battery cable is a much quicker and easier solution.

Welp, not sure where I am now. I woke up this morning to receiving the 10.1.0 update for Karaoke and Public Charging, but now I can't operate the vehicle from FordPass. Lock, Unlock, and enable HVAC all fail, but it seems to know where it is and reflects the correct-ish SOC. Other connectivity features in the vehicle work (Alexa, Charging Stations, etc).

What you are describing are Bluetooth issues and have nothing to do with the modem issues we have discussed. I would turn off Bluetooth on your phone and back on.
I can say for sure the mechanism is different because I can have none of the connectivity working but the app still works for lock/unlock etc if I am within Bluetooth range.

this update is wierd too in that the new features didn’t appear right away (last night). This morning though they were there and working. Just turn your truck off for a while if possible and see later in the day the status. Hopefully it will reset everything else back as well.

Climate controls are not tied to Bluetooth. I can initiate climate start/change well away from Bluetooth range of my truck.

Yes they all work outside of Bluetooth range as well but that will be consistent with the rest of the connectivity features. I guess they need to clarify how far from the truck they are trying these. There is also a case where connectivity works but the truck will have terrible cell service and things that require a feedback loop won’t work.

This is not a Bluetooth issue. If I am standing within site of the vehicle, I can operate all of these features. I'm in my office and the vehicle is parked the the parking garage 2 blocks away, it is using the internet and its modem. I use the HVAC feature most days to cool the vehicle before I get to it and now it's not working.

Where I park my truck I normally show 5 bars of signal strength and I've never had an issue until the modem lockup issue appeared. Of course the cell carriers could be having an issue today in the area or other interference. I have tried a few times today and won't give up. The anomaly is that it has transmitted it's correct location and correct SOC, so either some info is communicating or the communications were disrupted after I parked this morning.

The communication issue can be intermittent. It certainly can ping its location to the ford server and then cease to work further. I have seen that many times. I wonder if you were to start the truck now if the other communications would work. Having things work at random times has been the norm for me.
I have turned off Alexa right now and seeing how it does. I have a whole other thread somewhere from a couple months ago how I think the Alexa app is causing the issues to be worse or more frequent.

Help! Truck modem stops working/freezes up a lot, especially when using built in Alexa service with music (long post)

I do use Alexa functionality to run scripts to shut off lights and set the thermotsat in my house. The family just loves to turn on every light and leave them on (again, I realize I have become my father), but I stream Pandora through my Android Auto and don't play music through Alexa/Amazon Music.

Even in my home where we have an Echo in every room, we use Pandora "Alexa, Play Pandora". I never thought to have the Alexa app in the truck play music just because of my pattern with Pandora. I can possibly use it trying to play Amazon Music through Alexa in the Lightning as a litmus test to see if I can get the modem to lock up completely, but I don't believe it is a contributor in my case.

I'll be checking all of the connectivity in the truck as soon as I leave work to see if it is just an anomaly, if maybe local cell service is on the fritz, or maybe just the app doesn't like me anymore.

I've been trying the remote connectivity for 2 days for Lock/Unlock/HVAC and no go. Everything else has been working though. Connected Nav, Alexa, Charging Stations, Location, and reflecting correct-ish SOC.

So, I went ahead and unplugged the modem and plugged it back in.

Bingo, remote features started working again.

It seems to be yet another failure mode. Not being able to start my HVAC is a minor inconvenience in the grand scheme of things, but it's still something I'd like working as advertised in my brand new $80,000 truck.

@PrimeRisk . I have not used my Alexa app within sync for a week now, and have had no modem issues at all! I just used alexa/amazon music on my phone via carplay instead.
Interestingly enough the amazon music app on the phone locked itself up a couple of times where I had to re-start the app to get it working, but it had nothing to do with the truck.

I am going to re-enable the wake word and start using it in Sync a lot over the next couple of days to verify how fast the truck modem locks up.
