It's a documented issue but not catastrophic. 10 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.

At what mileage does the engine typically fail?

Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.

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.
