Owners who gave an odometer reading reported it at a median of 57,580 miles; half of them between 25,000 and 84,000. 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.
