I fully understand that and I agree, however this is not an issue with my 2014 F150 or 2014 and 2016 Fusion, nor any GM or Chrysler product I've owned. I honestly don't think this is due to water coming past the weatherstripping - as it popped up again once it got cold out this winter and I had not had a car wash in over a week. Normally I'm getting it washed every 2 or 3 days - it has no effect on the doors not wanting to unlock or not. And yes, the moonroof is "designed" to leak. I added some caulk to ensure the water isn't streaming into my truck but maybe a drop or two.
Recall 17S33 does not apply to any vehicle that had TSB 16-0155 completed. I had the TSB done - the recall is the same thing except it has updated parts. It consists of changing lock rods and adding water shields to the latches. TSB was done at the end of last winter - naturally with it being warm out until recently the doors/latches worked perfectly. I've since had all water shields replaced, they were redesigned for the TSB and they do look much improved. New latches put on the rear doors and new latches on order (backorder) for the front doors. The rear doors have been fine - but it's been a week, so time will tell. No ETA on latches for the front doors. Absolutely love the truck and I've only dealt with the door failing to latch shut once. That is a major safety issue. I have had the failing to unlock fairly often and is more of a hassle than anything, crawling thru the back to open up a front door. PITA and should not be happening on a $50,000+ vehicle. I have spent more time than I care to dealing with my dealer over this issue (they have been great but their hands are tied by Ford). I've resorted to taking videos of me unlocking the doors in the morning so there is no issue with them not being able to duplicate my concern.
I had hoped the recall would work - but given the responses here (https://www.f150forum.com/f118/2015-frozen-door-latch-tsb-recall-poll-status-402319/), it has not worked for many. Many have had latches replaced and that also is not working and now that latches are on national back order who knows. Ford has the means to get this issue figured out and resolved - but are they willing to spend that much $$$. That I don't know.
