I can understand some of those happening, but some consistency would be nice. My 2016 TH premium Beats audio has 9 (8 and sub) speakers. Now the Beats premium audio has 6 and a sub. Some THs came with matching wheels on the spare, some didn't. The rubber cover for the fuel door is not there, then it is, then it seems to be gone again. Some users can use the armrest usb to play media, some can only charge with it, and no one has been able to figure out why. It has nothing to do with 5.0 vs 6.5 either.It's called a "running change". Jeep is not the only manufacturer of cars or any other item to do this. Lots of factors come into play. Design not quite right, supplier not ready, blah blah blah.
Maybe because this is my first new vehicle and I've been keeping somewhat up to date on things, I am not used to this, but lack of a manufacturer being consistent on the same make, model, and year vehicle drives me nuts and I lose faith in a company like that. If two people order the same options on a vehicle, I would expect that both armrest USBs work as media players, the matching spare is there, and they have the fuel cap/cover. Regardless if they were built a few weeks/months apart. Or maybe it's just because I wanted the matching spare and the armrest to work as media player but didn't get it that is also drives me a bit batty.
