This has happened to me twice so far on my 2024 lariat ultimate. It only happens when it rains. It seems after I start the truck and drive and park. Everything works fine again. I personally think it has to do with the connectors that hang down next to the spare tire on the driver side in the rear. These connectors are just hanging vertically, allowing any water to drip down the connector and possibly into the connections. I feel there are a million other ways they could have secured these connections up and out of the way where they are not hanging down. At least put a rubber boot around the plug for extra weatherproofing.

If it continues to happen at each rain, I will have to bring it in. Seems no reason for this to be happening.

Scheduled next Friday for dealer to look at it

Took it to dealer today. Took about an hour. They got it working but said I needed to bring it back because there were 5 modules that needed a reprogramming. They were having internet trouble due to storms I assume. They couldn’t get all of them. At least the handles are working now.

Proximity Auto Unlocking
 

I have had an issue where I approach the SD and randomly once in a while it unlocks without even touching it. It doesn’t give me confidence when I drive in or out of my garage with my secondary vehicle.

mine does the same thing occasionally 🤷🏻‍♂️

DITTO!!
It has not done it in a couples of months now. So who knows....

I still need the dealer to program the other 5 modules they were talking about. Ford cares stepped in and I am finally going to get my right hand power stroke door badge replaced. Dealer told me it was 1 degree high on one side. I stuck my own digital degree meter on it and it is 4 degree higher. Ticks me off on a new truck. I’ll have it done when I get that fixed.

My door handles did not work yesterday. The truck woke up, the lights turned on, the mirrors and running boards deployed when I approached, but the door handles would not unlock the truck (MY24 F350 Limited). I tried touching the inside of the door handle and pushing the lock button on the door handle and it did not unlock the truck. I had to unlock the truck with the key fob. I was out of town for 5 days and this was the first time I tried to drive the truck. I ran some errands and drove about 20 miles total making multiple stops and the door handles did not work at any of the stops. This morning my door handles are fully functional. This has happened a couple of times (2-3) since I took delivery of my truck in December.

I am having this same problem with my 2024 F450 lariat.
I will drive the truck and then when I get to where I am going and shut the truck off and open the door, none of the lock or unlock buttons on the key fob, inside of door or the door handle work. I also cannot open my tailgate. Everything else works except anything that has to do with locking or unlocking the truck.

I let it sit for 2-3 hours, everything is back to normal. Until the next time I drive it.

I am driving it to the dealer tomorrow and will post an update as soon as they figure it out.

Hi there. Feel free to send us a DM with your vehicle's VIN and mileage and we'd be happy to look into getting you assistance with your key fob concern.

my exact situation...why isn't a video of it failing good enough? So frustrating. Mine are 100% cold and wet sensitive to the point I have to use the fob. I've owned a lot of super duties and this 2023 is the first I've experienced the issue so I know exactly how they are supposed to work.

I have this issue intermittently, as well. I also haven't figured out what makes my doors unlock as I approach the truck sometimes but not others.

It's also pretty irritating that the rear doors do not unlock when you grab the handle - our 2019 Expedition will lock/unlock on all four door handles.

I truly believe it has something to do with battery voltage and or over the air updates. Mine has not done it in a while but I have not had any updates in a while either. My truck was also stationary for about a week and everything worked fine. My belief is the truck goes into power saving mode during an update and it never comes out of it. It takes X number of starts or time after start(s) and it will exit that mode.

I use my truck daily and the problem recurs often.

I also asked about the update that would "fix" the main screen from returning to the same or default screen...no luck, wait for an update to be pushed. Really? We know there's a fix and it's now April 2024 and I'm driving a 2023...when exactly is that coming? :-)

I had this problem occur again today. I drove 70 miles, exited the truck and tried to touch the door lock and it did not work. I locked the truck with the key fob and then tried to unlock it with the door handle. Did not work. I tried it multiple times and the door locks did not work. I was away from the truck for about 45 minutes and when I came back to drive home, everything worked fine. There is definitely an issue with the proximity and door handles.
