I think people just have to remember that this is not a widespread problem that this is a very isolated issue and when people come to these forums they typically have problems they're trying to work out so you'l see all the brokens here ... It's like walking through the service shop at Ford with nothing but broken Fords that's all youl see, not representative of all Fords... Starting in the 17 Pacificas is the 3rd generation pentastar 3.6 were all of the top end bugs have been worked out and don't have the lifter ticking and rocker arm troubles for the most part anymore compared to the 1st and 2nd gen 3.6. People's engines that are going out at 70,000 miles could have been from many issues, low coolant levels, late oil changes, using the wrong oil or Weight oil, driven to hard, towed something to heavy etc.. Many variables all contributes.... These 3rd gen 3.6 motors are one of the best proven millions of miles and for the unlucky few where it blows a motor it's unfortunate but it happens.. Theoretically it has to happen to someone sometime.....Its not just pacificas.. anything using the 3.6 liter gas engine is suspect. The biggest issue is poor hardening of the rocker arms. You can hear a "tick, tick..tick" that sounds like a bad lifter or exhaust leak. Mine died in my 2015 TC at 60K miles. Took out the entire engine which was replaced under warranty. The service writer didn't even bat an eye when I pulled in. Knew exactly what it was without opening the hood. Took a month to get a new long block. The trans died 20K after that. I had extended warranty and I think after 2 months they are finally giving in this week to OK the work to fix it.
