UPDATE OF ISSUE ON MY 2023 PREMIUM AWD:
Background: At the time of 1st service attempt of issue, Ford dealer had said they couldn't communicate with camera module at all and ordered a new part. Due to some weather issues on West Coast part was delayed several days, but was received at dealership about a week after ordering.
Solution:
Dealership needed the car for about half a day in total to verify condition again and replace the camera module. Here is the text from the service receipt:
1 - LJ8Z*3G590*D MODULE - DRIVER STATUS MONITOR
AUTH CODE: 8544
PERFORMED ROAD TEST, VERIFIED CONCERN, CRUISE CONTROL IS INOPERATIVE. PERFORMED QUICK TEST, FOUND U2018:51 IN CMR. FOUND PPT L. L1 U2018 RETURNS, YES. L2 REMOVE FRUNK PANELS TO ACCESS BATTERY, ATTACHED CHARGER, PERFORM PMI OF CMR. PROGRAMMING FAILED, ATTEMPTED TO PROGRAM AGAIN, PROGRAMMING FAILED A SECOND TIME, INSTALL A NEW DRIVER STATUS MONITOR CAMERA MODULE. REMOVED LEFT FRONT DOOR WEATHERSTRIPPING, ACCESSED CMR MODULE, REPLACED MODULE, PERFORMED PMI, PERFORMED POST REPAIR ROAD TEST ON THE INTERSTATE, VERIFIED ALL BLUECRUISE FUNCTIONS WORK.
I took the car on an approx. 350 mile trip right after this repair, first half (approx 175 miles) was in heavy rain and I couldn't get BlueCruise to engage at all, or even get the notice that BlueCruise was available. Driver Assist functions did periodically work (hands on wheel self-driving). I don't recall BlueCruise before being so susceptible to rain, but return trip had only periodic very light showers and BlueCruise available and worked well about 80% of time. Driving was all on I-5 corridor between Seattle and Portland - I've not attempted BlueCruise anywhere between these points previously so I can't verify what part of the BlueCruise outages may have been due to mapping fidelity itself of the software vs. environmental effects (rain) vs. some other weird bug.
Summary: Still sounds like the Driver Status Monitor module was truly bad, but unknown what was root cause. Replacing module at dealer appears to have solved the issue. Total cost $0.
I'm happy to have BlueCruise back online of course, but I'm still wary of what was the cause of this and whether or not the OTA update specifically dealing with the driver camera had anything to do with it.
I will say that after the first cross-country trip in the car, having BlueCruise available was a game-changer for managing fatigue and improving overall driving experience. Nice to let someone else drive for a little bit
