Welcome to the forums.
As for the lifter issue, yes they happen, but I doubt it is as bad as most forums, or you tube, make it to be. When it come to reviews, or items like that, remember more people will complain than praise. Just take care of your truck, and perform required maintenance when do, and enjoy it. There are some that will suggest different way to lessen your chance of having it, but for myself I just follow the owners manual, for maintenance and go from there. And, knocking on wood, to date my engine has been fine for the last 80K miles...can't say the same for the transmission (but I have the 6 speed, not the 8).
When it comes to the Uconnect I can't help you, came after my truck (in fact my truck came with no Bluetooth or anything until I changed out the head unit for a Sony). There have been a few threads on here lately describing issues with new phones, that may be of help.
Enjoy your new truck, they are nice.
