Yipe. Seized engines. In their most profitable vehicles. And the cost of replacement engines is non-trivial, like a seat belt latch would be. Hyundai could tell Mary what a long running issue with engine oiling issues costs.
I wonder if the engines seize because they burned all their oil? Oil burning, from new, has become a common thing, in several brands of cars. People aren’t used to checking their oil all the time, like I did with my Thunderbird, 50 years ago.
