First off, I'm calling it door moulding while the dealer report calls it Weather Stripping and breaks it into "door side weather stripping" and "body side weather stripping".
Personally, weather stripping and moulding and gaskets can be extremely interchangeable so it's difficult to call it the official name and I hate sounding stupid! I've always purchased the Workshop Manual for each car I've owned, they're SO worth their weight and I really prefer the actual book to the CD. Books are easy to just flip through and see what catches your interest. Only problem is, on a 2016, the books would be super expensive (just a guess). I totally forgot, I still have the books for my 2006 Explorer and 2008 Expedition. I'm not mechanical BUT what I like them best for is it shows the best way of opening panels, access doors and the like without destroying the panel or clip. They come in handy in SO many ways. So after this posting, I need to put my service manuals for the '06 Explorer and '08 Expedition on eBay.
Anyway, call it what you will - I'm talking about the spongy strip that goes around the inside of each door to seal against the body whilst closed as well as the spongy thing that goes around the door entry of the car itself to seal against the door whilst closed which, to me anyway, is more like moulding. At the bottom of the car-body with the door open, there is another seal - and this one is more like the type in your house on the floor part of outdoor door jambs, just a "hump" of raised rubber to press against the bottom of the door when closed. To me, that's more like weather stripping - but hey, I'm not mechanic, no carpenter, I just buy the stuff at Home Depot to reseal windows!!
My car is under warranty for awhile so I don't need to worry just yet. But, aside from one of the door mouldings they replaced, I totally forgot the passenger front door moulding (spongy one!) was pulling apart where it comes together right in the middle of the door entry point - where it will get kicked and stepped on (both ends meet and terminate by slipping around a small "tube" to keep them in place - this is the one on the car itself, not the door. Really bad placement for a starting and terminating point for the moulding. It did pull apart and I've tried to slide one end back around the tube but the moulding/gasket/weather stripping/whatever you wish to call it has shrunk a bit so it's a tight fit.
My original plan, which I desperately need to start, was to have pen/paper in the car at all times and write ALL the little (or not so little) quirks and issues so that next time I go into the dealer for service I can just go through and get it all done in one shot. This current time around threw me for a loop because I wasn't planning on going in - when my Low Charge warning started, it went directly from work to San Tan Ford where I promptly forgot most of the things in my head!
As much as I love the Explorer - and I've wanted to upgrade from the Edge for a very long time - I've got to say that of the now 5 Fords in a row I've purchased, this definitely is the most disappointing. Don't get me wrong, I love the features, love the way it drives and handles - but as for Quality Control....can't say I'm thrilled for such a new-ish car.
