At what mileage does the engine typically fail?

A quarter of owners report trouble before 55,114; a quarter make it past 99,800. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
