The data is provided by CarMD's nationwide network of technicians.

Honda, Ford, and Chrysler rounded out the top-five most dependable brands.  That said, among the top-ten ranked automakers,Ford vehicles were the cheapest to repair, with an average cost of $309.55. Nissan vehicles earned the dubious distinction of being the most expensive, at a price of $430.83.
