In owners’ own words

On July 11, 2022 I was driving home when the MIL warning started flashing on my dashboard, and then my car began to stall. I was able to drive the car home and then have it towed to a local shop, who said that my oil was nearly gone and refilled it.
Engine seized and turned off unexpectedly and would not restart for hours. When it did start up a few seconds later it turned off again without driving this time. The battery, gas and oil were fine. It is now very very noisy and undrivable. There was a light ticking prior, but nothing concerning or I haven't heard most cars do.
The connecting rod bearing in cylinder 1 is bad and I noticed online alot of other models were listed with the same problem but not my model. My engine block needs to be replaced. Car has not been inspected by hyundai but just a licensed local mechanic because the dealerships said it would be months before they can look at it
So took my car for a recall at Hyundai which it was related to a camp 966 engine monitoring. The car has been turning off multiple times so took it to them and they told me it needs a new engine at only 60,000 miles on it
At 77,000 miles, with immaculate care taken of the engine with regular maintenance (and only 2 weeks since the previous oil change), the engine failed at the end of an 11.5 hour road trip and left me stranded on the side of a busy highway.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre engine problems common on the 2018 Hyundai Elantra?
They are documented: NHTSA holds 173 owner complaints naming the engine on this model year (52% of everything owners filed about it), and 53 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the engine on the 2018 Hyundai Elantra?
No recall campaign is filed under this heading for this model year (there are 1 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do engine problems show up on the 2018 Hyundai Elantra?
Owners who gave an odometer reading reported it at a median of 40,000 miles; half of them between 12,000 and 77,000. That is when reports cluster, not the life of a part.
What does NHTSA's "Engine" heading cover?
The engine and its cooling system. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
