This right here. I had a '12 Ram 1500 pre UConnect, a '14 Ram 1500 with the 8.4" Nav, and a '16 Ram 2500 with the 5.0 Uconnect. The '12 is the only one that work worth a damn. The UConnect on the '14 and '16 gave me nothing but trouble. The UConnect on the '16 was so problematic, I went through three warranty units in three months and either got defective units from Chrysler, or they did the same thing. After a month long wait for the fourth and nothing but excuses, I said the hell with it, dumped it, and bought my current Chevy. Best vehicle decision I've ever made. Between the issue with my Ram, and a huge issue I had with FCA corporate with my wife's '16 Charger, I'll never own another Chrysler product ever again.
Having said all that, it's going to take some pretty extreme incentives to get me to trade my '17 for a '19. It's nice, but lack of major improvements in the engine department have me underwhelmed.
