This has been known for years now and the literal graveyards of scrapped engines in both Kia and Hyundai dealerships prove it. Their machining is piss poor too. I have seen camshafts literally worn out even with proper oil changes (almost seemed like they forgot to harden the damn thing)
The fuel pipe coming out is nothing new, I have personally seen a ton of sportage/tucson/sonata/elantra with the quick connect clips not locked in on the fuel lines on brand new cars rolling off the truck, A horde of them having coolant leaks at the thermostat housing due to assembly line error.
A literal cancer of all Kia/Hyundai cars is that they cannot figure out how to get the windshield sealant dispenser to work properly at the assembly line. They leak like a sieve because the sealant was runny or bunched up from being too stiff.
