The Intelligent access of rear passenger side door stopped working. Intelligent access for the rest of the doors work. It's a 2020 Expedition Max XLT, 42000 mileage. Please suggest what I need to look into. Thanks in advance.

Check for any loose/unplugged cables under seat. Does it make any noise when you push the button ?

Try replacing the battery in your key fob as a first check as well. It's possible the fob battery is weak.
I had that happen to me before. The issue was that the battery in the vehicle was low on charge/weak. Does your start/stop still work? If you have noticed that hasn’t been doing it’s thing it’s a possibility that the battery is weak. On one of the menus I think the one that has your speedometer and assorted other things you can check your start/stop status and see what it says there. Mine did it during COVID when we didn’t drive that much and lucky for me the dealer replaced the battery under warranty.

My auto start/stop is turned on but it doesn't work. Weird thing is intelligent access for the rest of the doors work. Like others mentioned replacing the key fob battery may fix the issue. I have ordered the batteries from Amazon which will be delivered tomorrow. Will try that first. If that doesn't work then will have the main battery checked. Thanks to all for the quick response. I am glad that I have joined this forum of nice people.

Your vehicle is showing the classic signs of a dying battery. One-by-one the systems in the vehicle are shut off to preserve whatever charge remains in the battery. If you were to put it on a trickle charger overnight, the intelligent access will probably work again. Maybe even the Auto Start Stop, but probably not. Consider that to be a plus. If you install a new battery, all will work again like before.

I replaced the key fob battery but no luck. It may be the main battery that's failing.

I went to AutoZone to get the battery checked. They said, the battery is good but needs to be charged. Currently at 64%. They told me to take the battery out and bring it to AutoZone and they will charge is for free, usually takes 2 hours. Does trickle charger do the same? I never used trickle charger.

I lived this as well about a year ago. Battery was still under the three year/36,000 mile warranty. I had it to the dealer three times. My biggest concern is that the interior lights would go out in under a minute instead of the 10 minutes designed. The dealer paid for a rental car for five or six days to “run diagnostics“. I told them I thought it was the battery as I could charge it and it would work for a few days. They kept saying the battery checked normal. They spent more on the rental car then they would’ve spent on two Batteries. I bought a new interstate at Costco. All issues solved.
Hi All -
I have similar issues here. I bought a used 2018 model (Navigator) and the original battery worked but was weak enough that it was disabling some functions (I learned that here in this forum). The drive modes and ASS were disabled.
I charged the battery and drive modes were enabled. The IA "twitched" (seemed to try to function but did not fully) when I opened the door. ASS was not enabled.
I changed fob battery and put a new battery in the car and now have ASS but still no IA.
I have these codes:
B1337:01 - R/F Door external antenna
B1336:01 - L/F Door External Antenna
B1382:15 - R/F Door handle proximity sensor
I called my local dealer and they can't even figure out what parts I need but will charge me $200 to scan the codes and have service tell them what parts.
Any ideas from this thread on where to start? I'm wondering if the handles themselves have the antenna/sensor and are not working but I'm not sure.

Agree totally with Going_Going_Gone and Leadfoot17. Local auto parts store said the battery health was ok, but only at 39% charge. My little NoCo charger eventually kicked off with a "Bad Battery - Will Not Hold a Charge" indicator. A new battery solved all of the issues: IA on the passenger side, start/stop, radio shut off after 2 minutes instead of 10 minutes after engine stop. From what I've read, resetting the BMS is optional, but I did.
