What's wrong with engineers now days?

I am more disapointed in the enineering its self. Take the 3.8 V-6 in my 2010 Jeep unlimited. What a shitbox and most other people who own one think so too. I have heard plenty of people who have under 50K talk about how it burns oil. Lifter tick when you start it up after it sits for a couple hours. I wont get started about the power. I have always loved mopars but my jeep makes me think I should buy somthing else when I go to buy a new rig.
