Which year/model or engine? Worth noting many car manufacturers have struggled with timing chain issues on at least one engine. VW struggled with it on more than one engine, BMW, I’m pretty sure there was even a Honda or Toyota engine that had a weak timing chain system at some point. If they actually stopped making the engine because of it, good on them, because other manufacturers (especially VW) definitely don’t. Other Hyundai engines have rock solid reputations. One bad experience is called an anecdote, and it’s not a good reason to discredit a brand.
