Will Hyundai's Theta-III 4-cylinder engine be safe, especially with the bearing rods?

I personally had a 2015 Hyundai Santa Fe LWB and never had a problem. I think it is mainly due to the fact that it was V6. The cases for fires that is caused by engines of the V6 is rare. What's riddled with the problem is, the 4-cylinder ones. Especially with the Theta-II engines. They stall, catch fire, the pistons gather debris, make clicking sounds, and the bearing rods snap. It's all because of the poor bearing rods. They snap like crackers. They are not designed to withstand high pressure.
But I am hopeful that Hyundai is aware of this and make safety improvements on the upcoming Theta-III engines. Because V6 and V8 is slowly being phased out in Hyundai/Kia models, and we are stuck with these 4-cylinders.
I know many will doubt, but I also know that Hyundai is not stupid to keep this under the rug. In South Korea, many execs are caught by the authorities due to this faulty Theta-II engines.
And for these folks who tell me not to get a Hyundai, don't tell me to do so. Like I stated earlier, I owned a Hyundai and never had problems. I love Hyundai, and will buy them again... just not 4-cylinders if they're faulty (Most likely V6 that is sold in big SUVs and large sedans).
