THE VEHICLE WAS TOWED TO A FORD DEALERSHIP AND THE DIAGNOSIS WAS THAT THROTTLE BODY NEEDED REPLACING. THE SERVICE COST ME $503 PLUS TAX. *TR

At what mileage does the cruise control 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.
