  1. TSB 25-2048: Sync 4/4A General System Performance, Stability, and Intermittent System Reboot, etc.

    If you go into the vehicle menus and go to phone list, just turning off and back on the icon for CarPlay will re-connect and fix the audio. I think that is quicker than resetting the whole sync system.
  2. TSB 25-2048: Sync 4/4A General System Performance, Stability, and Intermittent System Reboot, etc.

    Do you have the latest version of the app on iOS? If so you need to completely close and restart the app.
  3. TSB 25-2048: Sync 4/4A General System Performance, Stability, and Intermittent System Reboot, etc.

    So I am very interested in seeing if anyone is successful getting a dealer to fix this. The only updates I have not yet received are 10.3 and VC 1.4, but today I still had Carplay wireless go out (was connected but no volume). The normal quick procedure fixed it like always, but I would like to...
  4. Absolute proof it’s an Onboard System issue -- modem not FordPass

    What do the icons on the top right of your center screen show? Assuming you have wifi turned on, when the truck is stopped you should have the Wifi symbol, and the up/down arrow icon. If the truck is moving then you will have cellular bars where the wifi icon was. They switch back and forth...
  5. 2023 Lightning Lariat - Heater Not Working

    I ended up having to add about 3.5 quarts total until it finally has a steady level. My heat has now returned to really good levels. That being said mine got progressively better each quart I added, so you may have a secondary issue. When it was bad I could feel my heat cycling on and back...
  6. 2023 ER Lariat Heater Went Out Just as Winter Hit

    Last follow up on this issue. I have now added about 3.5 quarts of coolant over the course of 4 different fills. It seems I had a lot of air to work out of the system after the battery was replaced back in May 24. It finally is staying at a constant level in the reservoir so I am confident...
  7. 2023 ER Lariat Heater Went Out Just as Winter Hit

    Update: I got the coolant and added about 1/4 gallon to get it about halfway between min/max. Ended up needing to drive about an hour and when I got home it had forced out the air. I was back down to where nothing could be seen. Added about another 1/4 gallon now to get back topped up, and...
  8. 2023 ER Lariat Heater Went Out Just as Winter Hit

    Thank you! So this appears to definitely be my issue. Coolant reserve is completely empty. Hope filling it up doesn't break my home integration system. Ordered the correct one off Amazon for same day delivery.
  9. 2023 ER Lariat Heater Went Out Just as Winter Hit

    I am sure I could research to find it, but does anyone have a quick response to what is the proper brand/type of coolant to use? I am pretty sure I have this same issue. I can hear the coolant sloshing around most days. I did have a battery replaced about 2 months before I really started to...
  10. Connectivity issues

    If you want the DIY method, you can unplug and replug the cable on the modem directly. This does involve removing the trim behind the rear passenger seat to get to it.
  11. Connectivity Dead - 2024 F-150 Lightning Lariat

    @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...
  12. Connectivity Dead - 2024 F-150 Lightning Lariat

    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...
  13. Connectivity Dead - 2024 F-150 Lightning Lariat

    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...
  14. Connectivity Dead - 2024 F-150 Lightning Lariat

    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...
  15. Connectivity Dead - 2024 F-150 Lightning Lariat

    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...
  16. Connectivity Dead - 2024 F-150 Lightning Lariat

    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...
  17. Connectivity Dead - 2024 F-150 Lightning Lariat

    No it really is one large fuse. There is nothing that actually says 8. It really should say 8/9.
  18. Connectivity Dead - 2024 F-150 Lightning Lariat

    It is a 2023 MY, although it has an october 2022 build date. Upon looking at the actual fuses it seems that fuse 8 and 9 are the same physically.
  19. Connectivity Dead - 2024 F-150 Lightning Lariat

    So I had my modem locked up all day, and just went and pulled fuse 32, which reset both my radio and my modem (it seems). I will say my comment on pulling fuse 32 doesn't work goes back to before I had fixed my battery voltage sensor, which I do think contributed to some of the issues. I will...
  20. Connectivity Dead - 2024 F-150 Lightning Lariat

    I don't seem to have a fuse 8. The Fuse box goes 4,5,7,9,11, etc.
