In owners’ own words

The primary failure is in the Engine/Powertrain system and Knock Sensor Detection System (KSDS), causing 6 identical sudden engine stalls (OBD-II code P1326) from 09/2000 to 06/2026. Additionally, severe excessive oil consumption was documented during 2 of these diagnostic visits, showing deep-seated engine issues.

The engine is burning the oil faster than normal. There are no oil leaks. Called the dealership and they said it’s an oil consumption. I got an oil change March 3,2023 and my oil pressure light came on last Friday April 14,2023 as I was driving I pulled over and there was completely no oil in the car.
Well below the 5000-mile mark for an oil change, multiple times between multiple oil changes my oil light would come on. I would be at a stop light and the oil light would come on as soon as I start going again. Checked the oil when I got home and there was barely any oil on the stick.
The engine is leaking oil in my garage. The car has 50,000 miles and is constantly loosing oil. It is 100% dealer maintained, and is current on all scheduled service

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 2019 Hyundai Sonata?
No recall campaign is filed under this heading for this model year. A bulletin is not a recall: it carries no federal duty to repair for free.
When do engine problems show up on the 2019 Hyundai Sonata?
Owners who gave an odometer reading reported it at a median of 81,000 miles; half of them between 32,000 and 126,000. 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.
