Reoccurring CAM and lifter failure

I bought the truck with 112,000miles on the OD 2-3 years ago. Ran great for 60,000 then heard lifter tick around 172,000 tried additives but the damage was already done, flat spotted a cam due to roller needle bearing failure. Replaced cam and lifters, on start I heard the same ticking that was there before I replaced cam and lifters. Checked clearances on everything valves are fine, push rods fine, rings fine, main/cam bearings fine. Will Chrysler just not admit they have too much of an aggressive planned obsolescence design, because they can’t afford to fix them all and instead, we will have to throw parts at it the whole life of the truck? Is this a common concern you hear?
