Common questions
How serious is the powertrain problem on the 2012 Acura MDX?

At what mileage does the powertrain typically fail?

A quarter of owners report trouble before 15,100; a quarter make it past 87,534. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain 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.
