Drivers in the District of Columbia also paid the most on average for parts at $261.60, where the most frequent repair was to replace a catalytic converter, accounting for 6.3 percent of recommended repairs in the district. Drivers in Michigan paid the least for parts at $194.43.

One factor, according to CarMD, was a rise in the number of mass air flow and catalytic converter repairs.

CarMD’s state ranking of repair costs was derived from an analysis of needed repairs identified for model-year 1996 to 2017 vehicles between Jan. 1, 2017 and Dec. 31, 2017 that were reported to and analyzed by CarMD’s team of technicians. The repairs were related to a vehicle’s OBD2 system. CarMD did not report on problems that were outside the scope of a vehicle’s OBD2 system.
