I don't know if the newer ones are different but a customer of mine has a 2013 Armada that I have done all the service on since brand new. About 150K on it now and it has had 0 issues with the engine, transmission, or any of the drivetrain except one CV axle that wore out because the boot got torn. Still starts up and runs like brand new. All that has needed replaced on it over the years is a starter, leaking power steering line, front wheel bearings, ball joints and control arm bushings. Very impressed with it for the most part. The 5.6 liter V8 has plenty of power and still runs like brand new.
