2017 ram 2500 broken manifold bolts

Has anybody said why there is such a problem with the bolts failing. I have an 05 Ram with 5.7 and no manifold exhaust leak, also have 102,000 miles on it. With all the problems with these new trucks, only lease them, and since it's just a matter of time that they will breakdown, dump them back to the Mfgr.. And now with all the computer BS in them there almost impossible to fix. If it's heating up and then cooling, engines have being doing that since day one. Or is it another case of trying to save a dime and use inferior parts.

Newer engines generally use 8mm or 5/16" manifold bolts. Just not enough meat in them. Not all will fail, but enough it is a problem. For those that fail, a warranty repair of removing the affected manifold to get the broken bolt out, replace all the bolts on that side with a new gasket is peanuts compared to the cost of the steel they saved. Most seem to get past the warranty period so it is not their problem.
