A quarter of owners report trouble before 37,000; a quarter make it past 80,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. 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.
